Mac For Acer

Posted on

For those who want to install Mac OS X Snow Leopard on an Acer Aspire One D250, this tutorial has been optimized for you. This tutorial can work on other sys. Acer Spin 5; Acer Nitro 5 Spin; Acer Aspire 5; HP Pavilion Wave; MORE: Alexa on Windows 10 Hands-On. How to Use Alexa on a Mac. If your machine doesn’t run Windows 10, you can’t download Alexa.


As many before me have done and many after will no doubt attempt, installing Mac OS X on a non-Apple piece of hardware is often a challenge where I suspect more fail then succeed.

I personally have successfully achieved this more than once and have sought to document the process that I succeeded with in as much detail as possible so that those attempting this can also succeed and hopefully contribute to this article by sharing their experiences.

This guide is all about getting Mac OS X onto your Acer Aspire One netbook (but could be used for many different netbooks potentially). I’m using the A150L model which has 1GB RAM and a 120GB hard disk but any of the Aspire Ones should work perfectly without deviating from any steps in this guide.

In this guide I’m installing from an 8GB thumb drive but you could use an external DVD drive and boot from DVD instead.

I will document this guide with as many screenshots and as much detail as possible and perhaps even a screenshow or two for the really tricky parts.

If you run into problems, there’s a massive community out there willing to provide suggestions or alternatives so just leave a comment and see how it goes!

And finally before you get going, good luck and hopefully in and hour or so you’ll have a (practically) fully functional Hackintosh!

What You’ll Need/Required Downloads

OK, here’s your shopping list.

Hopefully you’ve already got most if not all of the hardware and just need to download the software.

  • 1 x Acer Aspire One or your choice of Intel/AMD SSE2 hardware
    • You’re gonna wipe the drive on this baby so make sure there’s nothing you want to keep on it’s hard drive
    • We can however preserve the restore partition during this procedure so you can restore the AA1 to it’s original Windows or Linux preload if you like.
  • 1 x USB Thumb Drive (minimum 8GB)
  • 1 x working MAC to create the bootable thumb drive
    • It’s also possible to create the bootable thumb drive using Windows but I haven’t documented that yet!
  • 1 x blank DVD (optional)
    • This is only required if:
      • you have problems creating the USB Thumb drive and receive errors when Restoring the iDeneb ISO file to the thumb drive or
      • you would prefer to boot the Acer netbook using a DVD and an external USB DVD drive
  • 1 x DVD burner (optional)
    • If you need the blank DVD as above then I’m assuming you also have the DVD burner, right?
  • 1 x ISO File
    • iDeneb v1.1 10.5.4 – Universal for Intel/AMD with support for SSE2
      • I cannot provide you with a download link for obvious reasons but you shouldn’t have much problem finding it. (Googling would be a good start.)
      • When you’re downloading this save it to your Mac’s Desktop so we can get to it easily when required
  • Chameleon Bootloader
    • Download here
  • Diablo’s iDeneb 1.4 Tools
    • Download here
    • Download here
  • PC_EFI V10.1 Bootloader
    • Download here
  • ShutdownSound
    • This is used to fix a kernel panic when shutting down the AA1 when running on batteries
    • Download here
  • IOSDHCIBlockDevice.kext
    • This is to enable the Card Reader (SD)
    • Download here
  • Some patience, a little intelligence and a pinch of nerdiness

Stage 1 – Creating Bootable Thumb Drive

Pre-requisites For This Stage

  • ISO file downloaded and on the desktop
  • Working MAC booted up and at the desktop
  • USB Thumbdrive inserted
  • Chameleon Bootloader downloaded and extracted to a folder on your Desktop
  • PC_EFI V10.1 Bootloader download and on your Desktop
  • downloaded and Extra folder extracted to your Desktop

Steps For This Stage


  • You are following these steps at your own risk.
  • You can and possibly will destroy all data on the netbook at some point in this install so back it up if it contains valuable files!

Step 1 – Partition The USB Thumb Drive

  1. Open Disk Utility
    • Click Go > Utilities > Disk Utility
  2. On the left side, select your USB Thumb Drive
  3. Click the Partition tab on the right
  4. Under Volume Scheme select 1 Partition
  5. Click Options button
  6. Select Master Boot Record > Click OK
  7. On the right, enter a name for your Volume – I’m using MacBoot
  8. In the Format drop down field select Mac OS Extended
  9. Click Apply button
  10. When asked Are You Sure?, click the Partition button if you are sure.

Step 2 – Restore The ISO File To The USB Thumb Drive

  1. Still in Disk Utility, click the Images menu and then click Scan Images For Restore…
  2. Browse to where you saved your ISO file (mine’s on the Desktop), select it and click Scan
  3. At this point, one of two things will happen:
    • Your scan will be successful in which case you can proceed below when it’s complete
    • You will get an error message saying Unable to scan “filename.iso.” (Invalid Argument). If you get this error message then skip down to the Troubleshooting section at the bottom of this page.
  4. When you scan is complete, highlight your newly created partition on your thumb drive on the left hand side of Disk Utility
  5. Click the Restore tab on the right
  6. Drag your thumb drive partition from the left side (mines called MacBoot) into the Destination field on the right
  7. Drag your ISO file from the Desktop (or browse for it if you prefer by clicking the Image button) into the Source field on the right side
  8. Select Erase Destination checkbox
  9. Click Restore and Restore again

At this point, one of two things will happen

Your Restore process will chug away happily for a little while (enough time to get a coffee, believe me) and you can continue with the steps when it’s finished


You will receive an error message such as: Restore Failure. Could not find any scan information…If you get this error message then skip down to the Troubleshooting section at the bottom of this page.

Step 3 – Make The Thumb Drive Bootable

  1. If you haven’t already done, close Disk Utility but leave your Thumb Drive inserted
  2. Open Terminal. You can find this in Applications > Utilities
  3. Type diskutil list and press enter. You will see something similar to image below.
  4. Take a note of the number of the disk under the IDENTIFIER column as circled in red below. As you can see, mine is 1 (One) (i.e disk1 and disk1s1)
  5. Now you need to change directory into the i386 directory which is inside the Chameleon directory that you extracted to your Desktop. You can do this by issuing the cdcommand and typing the remainder of the path which would be something like:
    • cd /Users/your_username/Desktop/Chameleon-2.0-RC2-r640-bin/i386
    • Tip! A quick and easy way to do this in Mac OS X is to type cd and then simply drag the i386 folder (yes using your mouse) right into the Terminal window and releasing the mouse button. It will fill in the correct path for you. Isn’t Mac wonderful 🙂
    • When you’ve entered the correct cd command, hit Enter.
  6. Now enter the following commands and be sure to swap the items in red with the correct ones from your system as discussed in step 4 above and press Enter after each. You may be asked to enter your password. Just enter it and press Enteragain.
    • sudo fdisk -f boot0 -u -y /dev/rdisk1
    • sudo dd if=boot1h of=/dev/rdisk1s1
    • sudo cp /Users/your_username/Desktop/boot /Volumes/MacBoot
  7. Close Terminal
  8. Back on your Desktop, you should have downloaded and extracted
    • If not go back to the “What You’ll Need” stage of this article and download it.
  9. Now copy the Extra folder (a simple drag n’ drop is fine) from the Desktop into the root directory of your Thumb Drive
  10. That’s it! Mac OS X Bootable USB Thumb Drivecreated.
    • Make sure it looks similar to the image below. The most important of folders being highlighted in red.

Stage 2 – Booting From The Thumb Drive & Installing OS X

Pre-requisites For This Stage

  • Bootable USB Thumb Drive (or bootable DVD if you prefer) has been successfully created

Steps For This Stage

Warning: You are following these steps at your own risk. You can and possibly will destroy all data on the netbook at some point in this install so back it up if it contains valuable files!

Step 1 – Boot Up & Begin Install

  1. Make sure the netbook is switched off but connected to mains power.
  2. Insert your USB Thumb Drive into the Acer Aspire One
  3. Switch on the netbook
  4. When you see the Acer splash screen press F12
  5. When presented with the Boot Menu, select your USB Thumb Drive and press Enter. It should be list as USB HDD: …
  6. Now you should see the Acer booting from the Thumb Drive with a nice Apple boot screen. Let it boot as far as the language selection screen
  7. Select your language and press Enter
  8. At the Welcome screen, click Utilities and then Disk Utility
  9. In Disk Utility, you should see your Acer’s hard-disk in the left pane. Mine is partitioned into two partitions, one for the OS and one for the recovery partition. In this guide I will leave the recovery partition intact.
  10. Select the larger of the two partitions (mine’s name disk0s1) and click Erase tab on the right
  11. Select Mac OS Extended in the Volume Format field
  12. Enter a name for your partition
  13. Click Erase.. button and the Erase again.
  14. When complete, quit Disk Utility (Alt+Q)
  15. Back at the Welcome screen, click Continue, Agree
  16. At Select a Destination screen select the partition/volume you just erased and click Continue
  17. At Install Summary screen click Customize
  18. On the Customize screen select iDeneb Essentials and Netbook > Acer Aspire One A150
    • Note: These options will be different depending on the iDeneb release you are using. Try to get the very latest!
  19. Click Done
  20. Click Install
  21. Get Coffee

Stage 3 – Post-installation Steps

Pre-requisites For This Stage

  • Diablo’s iDeneb Tools downloaded and on another USB Thumb Drive so we can transfer it onto the Acer

Steps For This Stage

Step 1 – First Boot After Install

  1. On the first boot after the installation process is complete you will see the words Darwin boot. If you miss them first time don’t worry, just power off and back on again. When you do see them press ANY key. (don’t ask me where the ANY key is Homer)
  2. Type -x and press Enter
  3. Mac OS X will now boot in Safe Mode. Enter personal information, skip registration
  4. Select keyboard preferences
  5. Create your user account and password
  6. On the Acer, when you have reached the Mac Desktop for the first time, insert the USB Thumb Drive with Diablo’s iDeneb Tools on it
  7. Copy or (depending which one you downloaded) from the USB Thumb Drive to the Desktop and extract it by double clicking the file. You should now have a folder on the Desktop.
  8. Open the folder and double click DoNotSleep.mpkg. Follow the install steps until completion.
  9. Now double click GMA950.pkg. Follow the install steps until completion.
  10. Now copy OSX86Tools from the folder onto your Desktop.
  11. Delete the folder.
  12. Remove the USB Thumb Drive and restart the Acer Aspire One

Step 2 – Enabling Quartz GL using OSX86Tools

  1. After the restart when you are on your Desktop in normal mode, double click OSX86Tools
  2. In the top left of the window, click Enable/Disable Quartz GL
  3. Enter your password if prompted
  4. In the next pop-up window click Enable Quartz GL
  5. Restart the Acer Aspire One

Step 3 – Repair Permissions

MacMac address for acer chromebook
  1. After the restart when you are on your Desktop in normal mode, double click OSX86Tools
  2. Place a checkmark in the Repair Permissions check box
  3. Click OK to the confirmation
  4. Restart the Acer Aspire One

Stage 4 – Wireless (WiFi) Card


As far as I can tell, this is a lottery and depends what Wireless card you got with your model of Acer Aspire One.

My Acer Aspire One is the AOA150-AW and it comes with the Atheros AR5BXB6 and it does NOT work no matter what I do.


So, this stage will document the steps you need to take to replace the wireless card with a reliable, known compatible card for Mac OS X. Believe me, this will save you hours of wasted time, frustration and heartache and for a meagre few dollars.

You can get a reliable Mac OS X compatible card on eBay very cheaply!

Prerequisites for this Stage

  1. Do some homework (i.e. googling) and find a card that will be reliable and stable in your netbook. A good place to start is by checking the HCL on osx86project. Here’s the link: Hardware Compatibility List.
  2. If you were to ask me what card I recommend, I would choose the BCM94321MC by Broadcom. This Wireless card is shipped by Apple in some of their Mac Pro’s and is the one I use and it has never let me down once and required zero effort to install. Literally plug n’ play (oh how MS does that sound!)
  3. When you have found your card of choice, ordered it and opened the box you now need to get under your Acer Aspire One’s hood and replace the card. Here’s the instructions:

Steps for this Stage

  1. Turn your Acer Aspire One upside down and lay flat on a solid surface
  2. Remove the battery
  3. Under the battery, remove the three small screws
  4. Carefully peel back the two black rubber feet to the left and right of the battery area
  5. Remove the screws that are under the black rubber feet
  6. Remove the three screws at the opposite side of the case i.e. towards the front of the machine
  7. Flip the AA1 back over and open the screen
  8. There are three plastic tabs at the top of the keyboard – Above the F2, F8 and Pause/Break keys. Carefully, push these tabs inward with something small and pointy and at the same time gently lever the keyboard upwards by getting under the Esc key.
  9. Once you raised the keyboard enough to get under it properly, gently go around the edges and release the whole thing. Be careful not to lift it too far as there is a ribbon cable beneath it connecting it to the netbook’s motherboard.
  10. Once the keyboard released, lift the small black tab on the ribbon cable connector. Release the ribbon cable. Set the keyboard aside.
  11. Release the small black tab on the tiny ribbon cable connecting the mouse pad.
  12. Remove 6 screws. 2 on the left, 2 towards the middle and 2 on the right.
  13. Once removed, you need to gently leaver the main casing off. I did this by getting my finger under the left corner and working my way around.
  14. Once removed, the wireless card is at ooo 6 o’clock-ish… it’s the little card with two wires stuck onto it and it has one screw. Remove the screw and disconnect the two wires. They should just pop off easily.
  15. Now reverse all steps to install the new card you have.

Stage 5 – Card Reader (SD Only)

Pre-requisites For This Stage

  • downloaded and extracted to your Desktop

Steps For This Stage

  1. Open Finder and browse to
    • /System/Library/Extensions
  2. Locate the file IOSDHCIBlockDevice.kext and move it to the trash (enter password if requested)
  3. Now drag the file IOSDHCIBlockDevice.kext (the one you downloaded from above) from your Desktop into the /System/Library/Extensions folder
  4. Click Authenticate (if asked)
  5. Enter your password (if asked)
  6. Click Applications > Terminal
  7. Enter the following and press enter:
    • sudo chown -R root:wheel /System/Library/Extensions/IOSDHCIBlockDevice.kext
  8. Enter your password (if asked)
  9. Shutdown
  10. Insert an SD card
  11. Start your AA1 and your SD Card should appear mounted on the desktop

Disk Utility Error Message – “Unable to scan “filename.iso” (Invalid argument)”

If you receive this error then try creating a DVD from the ISO image that you are trying to scan.

You can do this by clicking the Burn button at the top of Disk Utility, inserting a blank DVD, selecting your ISO file from the Desktop (or wherever you have it) and clicking Burn.

This will create a DVD version of your ISO file. This DVD will be bootable and if you have an external DVD drive you may plug it into the Acer Aspire and forget about the thumb drive.

Alternatively, if you want to continue with the Thumb Drive option then finish burning your DVD, go back up to Step 2 above (Restore procedure) and instead of dragging your ISO file in to the Source field, drag the DVD drive from the left side and continue the rest of the steps.

If it still doesn’t work then create a new ISO File from the DVD you just made by clicking the New Image button in Disk Utility and then when that’s created drag this new ISO File into the Source field instead during the Restore procedure.

Disk Utility Error Message – Restore Failure. Could not find any scan information. The source image needs to be imagescanned before it can be restored.

If you receive the above message it means you need to scan your ISO or DMG file before performing the Restore procedure.

You can do this by clicking the Images menu, clicking Scan Image for Restore…, select the image click Scan.

When it’s finished, try the Restore procedure again.


Between mid October 2019 and mid February 2020 everyone in the Army was migrated to use their PIV Authentication certificate for Email access. You no longer use the Email certificate for Enterprise Email or any CAC enabled websites

Mac users who choose to upgrade (or already have upgraded) to Mac OS Catalina (10.15.x) will need to uninstall all 3rd Party CAC enablers per AND reenable the built in smart card ability (very bottom of macuninstall link above)

If you purchased your Mac with OS Catalina (10.15.x) already installed, you can skip the uninstall part above and follow the instructions below.

6 'high level' steps needed, follow down the page to make this a painless systematic process

1.Is your CAC reader 'Mac friendly'?
2.Can your Mac 'see' the reader?
3.Verify which version of Mac OS you have
4.Figure out which CAC (ID card) you have
5.Install the DoD certificates
5a.Additional DoD certificate installation instructions for Firefox users
6.Decide which CAC enabler you want to use (except for 10.12-.15)

Step 1: Is your CAC reader Mac friendly?

Visit the USB Readers page to verify the CAC reader you have is Mac friendly.

Visit the USB-C Readers page to verify the CAC reader you have is Mac friendly.

'Some, not all' CAC readers may need to have a driver installed to make it work.

NOTE: Readers such as: SCR-331 & SCR-3500A may need a firmware update (NO OTHER Readers need firmware updates).

Information about these specific readers are in Step 2

Mac acer monitor no signal

Step 2: Can your Mac 'see' the reader?

Plug the CAC reader into an open USB port before proceeding, give it a few moments to install

Step 2a: Click the Apple Icon in the upper left corner of the desktop, select 'About This Mac'

Step 2b: Click 'System Report...' (button)

Step 2c: Verify the CAC reader shows in Hardware, USB, under USB Device Tree. Different readers will show differently, most readers have no problem in this step. See Step 2c1 for specific reader issues.

Step 2c1: Verify firmware version on your SCR-331 or GSR-202, 202V, 203 CAC, or SCR-3500a reader. If you have a reader other than these 5, Proceed directly to step 3

Step 2c1a-SCR-331 reader

If your reader does not look like this, go to the next step.

In the 'Hardware' drop down, click 'USB.' On the right side of the screen under 'USB Device Tree' the window will display all hardware plugged into the USB ports on your Mac. Look for “SCRx31 USB Smart Card Reader.” If the Smart Card reader is present, look at 'Version' in the lower right corner of this box: If you have a number below 5.25, you need to update your firmware to 5.25. If you are already at 5.25, your reader is installed on your system, and no further hardware changes are required. You can now Quit System Profiler and continue to Step 3.

Step 2c1b-SCR-3500A reader

If you have the SCR3500A P/N:905430-1 CAC reader,you may need to install this driver, as the one that installs automatically will not work on most Macs. Hold the control key [on your keyboard] when clicking the .pkg file [with your mouse], select [the word] Open

Step 3: Verify which version of MacOS do you have?

(You need to know this information for step 6)

Step 3a: Click the Apple Icon in the upper left corner of your desktop and select 'About This Mac'

Step 3b: Look below Mac OS X for: Example: Version 10.X.X.

Step 4: Figure out which CAC (ID Card) you have

(You need to know this information for step 6)

Look at the top back of your ID card for these card types. If you have any version other than the six shown below, you need to visit an ID card office and have it replaced. All CACs [other than these six] were supposed to be replaced prior to 1 October 2012.

Step 5: Install the DoD certificates (for Safari and Chrome Users)

Go to Keychain Access

Click: Go (top of screen), Utilities, double click Keychain

(You can also type: keychain access using Spotlight (this is my preferred method))

Select login (under Keychains),and All Items (under Category).

Download the 5 files via links below (you may need to <ctrl> click, select Download Linked File As... on each link) Save to your downloads folder

Please know... IF You have any DoD certificates already located in your keychain access, you will need to delete them prior to running the AllCerts.p7b file below.,,,, and

Double click each of the files to install certificates into the login section of keychain

Select the Kind column, verify the arrow is pointing up, scroll down to certificate, look for all of the following certificates:

DOD EMAIL CA-33 through DOD EMAIL CA-34,

DOD EMAIL CA-39 through DOD EMAIL CA-44,

DOD EMAIL CA-49 through DOD EMAIL CA-52,


DOD ID CA-33 through DOD ID CA-34,

DOD ID SW CA-45 through DOD ID SW CA-48,

DoD Root CA 2 through DoD Root CA 5,

DOD SW CA-53 through DOD SW CA-58, and

DOD SW CA-60 through DOD SW CA-61

NOTE: If you are missing any of the above certificates, you have 2 choices,

1. Delete all of them, and re-run the 5 files above, or

2. Download the file and install each of the certificates you are missing individually.


Error 100001 Solution

Error 100013 Solution

You may notice some of the certificates will have a red circle with a white X . This means your computer does not trust those certificates

You need to manually trust the DoD Root CA 2, 3, 4, & 5 certificates

Double click each of the DoD Root CA certificates, select the triangle next to Trust, in the When using this certificate: select Always Trust, repeat until all 4 do not have the red circle with a white X.

You may be prompted to enter computer password when you close the window

Once you select Always Trust, your icon will have a light blue circle with a white + on it.

The 'bad certs' that have caused problems for Windows users may show up in the keychain access section on some Macs. These need to be deleted / moved to trash.

The DoD Root CA 2 & 3 you are removing has a light blue frame, leave the yellow frame version. The icons may or may not have a red circle with the white x

or DoD Interoperability Root CA 1 or CA 2 certificate
DoD Root CA 2 or 3 (light blue frame ONLY) certificate
or Federal Bridge CA 2016 or 2013 certificate
or Federal Common Policy CAcertificate
or or SHA-1 Federal Root CA G2 certificate
or US DoD CCEB Interoperability Root CA 1 certificate

If you have tried accessing CAC enabled sites prior to following these instructions, please go through this page before proceeding

Clearing the keychain (opens a new page)

Please come back to this page to continue installation instructions.

Step 5a: DoD certificate installation instructions for Firefox users
