Built-in iSight cameras: iSight’s built-in cameras are currently not working properly on some machines. It’s likely to work but know before you install it, your iSight camera may not work.

Trackpad (MacBook 5.2 only). The trackpad in MacBook5.2 is not fully supported in High Sierra. Although it works and is fully usable, High Sierra detects it as a normal mouse, preventing you from changing some trackpad-oriented settings.

Macs that use the Broadcom BCM4321 (BCM94321) WiFi will not have functional WiFi when high Sierra is launched, and support for these modules has been discontinued since macOS Sierra. This usually applies to MacPro3.1, MacBook5,2, MacBookPro4,1, iMac8.1, Macmini3.1, and MacBookAir2.1 computers. Please note that not all of these machines will have an unsupported map. It is just a list of machines that are known to come with this card in some configurations.

You can find out that you have an unsupported card by opening System Profiler (click on Apple’s Mac’s System Report) and click on Wi-Fi in the Network section. Note the value for the map type field.

Below are ID Wi-Fi modules that don’t work in High Sierra:

  • (0x14E4, 0x8C)
  • (0x14E4, 0x9D)
  • (0x14E4, 0x87)
  • (0x14E4, 0x88)
  • (0x14E4, 0x8B)
  • (0x14E4, 0x89)
  • (0x14E4, 0x90)

FOR EXAMPLE, any ID not listed above (0x14E4, 0x8D) is a supported card and will work great in High Sierra.

How to install macOS High Sierra on unsupported Mac? 5 Easy Steps with Patch file

1. Insert your USB drive (remember at least 16GB), open the disk utility, and format it as OS X Extended (Journaled). For reference, follow the snapshot below:

2. Open the previously downloaded “macOS High Sierra Patcher” utility and find your copy of the macOS High Sierra Installer program, usually a macOS installer that is usually used to download into the Applications folder. For reference, follow the snapshot below:

There should be a window that the utility successfully checked the application macOS High Sierra Installer. Click OK. For reference, follow the snapshot below:

3. Then select the USB drive in the drop-down list on the right and press the “Start Operation” wide button. For reference, follow the snapshot below:

4. When the installation flash drive is ready, it is necessary to load it from it. To do this, turn off the Mac and turn it on again, holding the Option (Alt) button and select the macOS High Sierra. For reference, follow the snapshot below:

Note: Follow steps 5 and 6 if you want to do a clean installation. If you already have experience installing macOS, you can skip these steps and install the High Sierra operating system on that previous version of OS X, after which an on-site update will be performed.

5. Once the installation program is loaded, open the Disk Utility from the utility menu or double-click it in the utility window in the bottom left corner of the screen.
For reference, follow the snapshot below:

6. Select the drive or section you want to install macOS High Sierra on and click Erase, then select Mac OS Extended (Journaled) or APFS. When you format the entire disk, make sure you select the GUID markup.

  • Use APFS for 2009 models and later, will work, as on macOS High Sierra.
  • It’s a good idea to use APFS only if you’re installing High Sierra on an SSD drive.

If you have a Mac that didn’t initially support High Sierra (and therefore can’t download from the APFS volume initially), please note:

  • If you use APFS, you won’t have a Recovery HD.
  • If you decide to use APFS, the loader will be installed by the utility later, as the built-in software of these unsupported machines does not support the loading from the APFS volumes. This is not exactly a native (native) download method, but it won’t cause any working High Sierra. The demo process of such a download can be seen below.

7. Next, install the MacOS High Sierra as usual on the desired volume.

It should be noted that if you install the operating system on an officially supported Mac model for any reason, then at this stage, the installation is complete, and you don’t need to do 8-11 steps. Just reboot your Mac.

8. Once the installation is complete, restart again by holding the Option (Alt) key and select the macOS High Sierra again. Once downloaded, open the “mac OS Post Install” app. For reference, follow the snapshot below:

9. You’ll open a window from the top in the “Choose your Mac Model” section of the drop-down list to choose your Mac model. Once you’ve selected the Mac model, the optimal checkboxes (ticks) will be marked automatically for your model. You can also tick other ticks of your choice you don’t need them.

10. At the bottom of the Select Volume section in the drop-down list, select the volume you just installed on Mac OS High Sierra and click “Patch.” When the utility installs all the patches, you select click “Reboot.” The Mac can rearrange the cache within minutes before restarting.

If the system doesn’t work properly after the restart for some reason, download back to the installation drive, re-start “mac OS Post Install” and select “Force Cache Rebuild” before restarting. In most cases, this is not necessary.

11. After the restart, your Mac should be loaded into a fully operational operating system macOS High Sierra.

For more information:

High Sierra installs the “Patch Updater” program in the Application/Utility folder when you install The Mac OS Post Install tool. This program will alert you when new patch updates are available for your machine and ask you to install them. If you don’t have Patch Updater installed, but you want to install it, you can download and install this program, click on the link and unpack the archive after downloading it.

Reinstalling patches:

During the macOS High Sierra update, some of our fixes may be overwritten. You can reinstall these fixes with a click to update the patches. To do this, open the Patch Updater app and select “View Installed Updates” or use the “View and Show Installed Updates” menu in the menu line.

To re-install one of the patches, click the right button on it in the list and select “Re-install…”. You can also click “Re-install All” to reinstall all installed fixes at once.


System updates, such as 10.13.1, should be installed as normal if “Software Update Patch” has been tagged in the mac OS Post Install tool or you installed it later using InstallPatchUpdater. If for some reason, updates don’t show up or are installed incorrectly, you need to reinstall the software update fix with the Patch Updater app.

If the system doesn’t start properly after the update is installed, you’ll need to download the corrected install volume and re-start the fix after installing it on the High Sierra volume. Make sure you choose “Force Cache Rebuild” before the reboot.

What you need to create a bootable installer

  • A USB flash drive or other secondary volume formatted as Mac OS Extended, with at least 14GB of available storage
  • A downloaded installer for macOS Big Sur, Catalina, Mojave, High Sierra, or El Capitan

Download macOS

  • Download: macOS Big Sur, macOS Catalina, macOS Mojave, or macOS High Sierra
    These download to your Applications folder as an app named Install macOS [version name]. If the installer opens after downloading, quit it without continuing installation. To get the correct installer, download from a Mac that is using macOS Sierra 10.12.5 or later, or El Capitan 10.11.6. Enterprise administrators, please download from Apple, not a locally hosted software-update server.
  • Download: OS X El Capitan
    This downloads as a disk image named InstallMacOSX.dmg. On a Mac that is compatible with El Capitan, open the disk image and run the installer within, named InstallMacOSX.pkg. It installs an app named Install OS X El Capitan into your Applications folder. You will create the bootable installer from this app, not from the disk image or .pkg installer.

Use the 'createinstallmedia' command in Terminal

  1. Connect the USB flash drive or other volume that you're using for the bootable installer.
  2. Open Terminal, which is in the Utilities folder of your Applications folder.
  3. Type or paste one of the following commands in Terminal. These assume that the installer is in your Applications folder, and MyVolume is the name of the USB flash drive or other volume you're using. If it has a different name, replace MyVolume in these commands with the name of your volume.

Big Sur:*



High Sierra:*

El Capitan:

* If your Mac is using macOS Sierra or earlier, include the --applicationpath argument and installer path, similar to the way this is done in the command for El Capitan.

After typing the command:

  1. Press Return to enter the command.
  2. When prompted, type your administrator password and press Return again. Terminal doesn't show any characters as you type your password.
  3. When prompted, type Y to confirm that you want to erase the volume, then press Return. Terminal shows the progress as the volume is erased.
  4. After the volume is erased, you may see an alert that Terminal would like to access files on a removable volume. Click OK to allow the copy to proceed.
  5. When Terminal says that it's done, the volume will have the same name as the installer you downloaded, such as Install macOS Big Sur. You can now quit Terminal and eject the volume.

Use the bootable installer

Determine whether you're using a Mac with Apple silicon, then follow the appropriate steps:

Apple silicon

  1. Plug the bootable installer into a Mac that is connected to the internet and compatible with the version of macOS you're installing.
  2. Turn on your Mac and continue to hold the power button until you see the startup options window, which shows your bootable volumes and a gear icon labled Options.

  • Catalina: /Applications/Install macOS Catalina.app/Contents/Resources/createinstallmedia

  • High Sierra: /Applications/Install macOS High Sierra.app/Contents/Resources/createinstallmedia

R/osx: Reddit's community for users, developers, and hackers of Mac OS X – the desktop operating system from Apple. Mac OS X is no longer being called OS X, and Apple is not promoting Sierra with a version number either (however, it is internally identified as OS X 10.12).Now it’s simply macOS Sierra – in keeping with iOS, tvOS, and watchOS. MacOS Sierra was released on Sept. 20, 2016 and officially requires a supported Mac with at least 2 GB of system memory and 8.8 GB of available storage space.

While the yearly major macOS update system is free to install, it is still limited to Macs that Apple deems compatible, and every year a generation of Macs essentially becomes obsolete. This is despite the fact that Apple is eager to emphasize that macOS is a widely compatible operating system.

As it happens, there are still people with close to ten-year-old Apple desktop computers still in use on a daily basis, likely performing a range of lighter tasks.

Which Macs Don't Support High Sierra

For some reason Apple doesn't want to allow these Macs to run its latest operating system, currently macOS 10.13 High Sierra. This leaves the following Macs on macOS 10.11 El Capitan:

  • MacBook Pro – late-2009 or earlier models
  • MacBook – late-2008 or earlier models
  • MacBook Air – 2009 or earlier models
  • iMac – late-2008 or earlier models
  • Mac Mini – 2009 or earlier models
  • Mac Pro – 2009 or earlier models.

These machines are considered obsolete and vintage by Apple. The company defines vintage products as those that have not been manufactured for more than five years but less than seven years ago. Obsolete products are those discontinued more than seven years ago.

How to Install macOS High Sierra on Unsupported Macs

Though Apple doesn't support the above hardware officially, someone has thought about sharing the love for these older machines. A developer known as DOSDude1 has written a patch that works on Macs with the Penryn architecture. Using this still imposes certain limitations, but at least makes it possible to install macOS High Sierra on the following Macs:

  • Early-2008 or newer Mac Pro, iMac, or MacBook Pro (MacPro 3,1 and 4,1, iMac 8,1 and 9,1, MacBook Pro 4,1, 5,1, 5,2, 5,3, 5,4, and 5,5).
  • Late-2008 or newer MacBook Air or Aluminum Unibody MacBook (MacBook Air 2,1, MacBook 5,1).
  • Early-2009 or newer Mac Mini or white MacBook (Mac Mini 3,1, MacBook 5,2)
  • Early-2008 or newer Xserve (Xserve 2,1, Xserve 3,1).

If you happen to own any of the Penryn Macs mentioned above, the macOS High Sierra Patch Tool written by DOSDude1 will make running the latest software possible. But remember, with High Sierra you will also migrate to the Apple File System, and it is highly recommended that you first disable SIP because it may prevent the patch from working at all.

Installing the operating system on any of these Macs will require some technical knowledge, so it is not recommended for novice users. Also, a backup of your data is always a good idea in case anything goes wrong.

While there is a full step-by-step tutorial and video tutorial available on DOSDude1's website, it’s good to get a summary of the basics, which start with downloading the macOS High Sierra Installer app from the Mac App Store:

  1. Format a USB drive as Mac OS Extended (Journaled) via Disk Utility.
  2. Open the macOS High Sierra Patcher tool, navigate to the High Sierra Installer App, then select your pen drive and click “Start Operation”.
  3. Boot from the USB drive by holding down the option key after reboot.
  4. Install macOS normally, reboot back on the installer drive, and then open the “macOS Post Install” application.
  5. From the options, select the Mac model you own. This step is important, because it contains the optimal patch for that specific model.
  6. Click the “Patch” button, and after the process has finished, click “Reboot”.

The Reason Not To Install macOS High Sierra on an Unsupported Mac

As you may have already experienced with other types of officially unsupported machines, the probability of having issues is much higher. The same applies in this case, too, since the macOS High Sierra Patcher will render your iMac 8.1 Broadcom Wi-Fi chip useless for certain models.

Macs that use the Broadcom BCM4321 Wi-Fi module will not have functional Wi-Fi when running High Sierra. Another issue that has been highlighted by the developer is that the trackpad in the MacBook 5,2 isn't fully supported in this version of OS.

These are just a few of the possible issues that could arise, and this is before even mentioning the various potential software errors that you can run into by using out-of-date hardware. Without getting the proper knowledge beforehand, you'll need to revert back to the previous state of the Mac, which won't be an easy process, especially not without a Time Machine backup.

For the first time since Apple released OS X 10.8 Mountain Lion in July 2012, Apple has dropped support for a number of older Macs that had supported OS X 10.8 through 10.11 El Capitan. No MacBook and iMac models prior to Late 2009 and no MacBook Air, MacBook Pro, Mac mini, and Mac Pro models prior to 2010 are officially supported by macOS Sierra, although workarounds have been developed for most unsupported 2008 and 2009 Macs.

Mac OS X is no longer being called OS X, and Apple is not promoting Sierra with a version number either (however, it is internally identified as OS X 10.12). Now it’s simply macOS Sierra – in keeping with iOS, tvOS, and watchOS.

macOS Sierra was released on Sept. 20, 2016 and officially requires a supported Mac with at least 2 GB of system memory and 8.8 GB of available storage space. (We recommend at least 4 GB of RAM.)

Officially Supported Macs

All Late 2009 and later MacBook and iMac models are supported in macOS Sierra, as are all 2010 and newer MacBook Air, MacBook Pro, Mac mini, and Mac Pro computers.

Hacking macOS Sierra for Unsupported Macs

Hardware requirements for macOS Sierre include a CPU with SSE4.1, so it cannot be run on any Mac with a CPU prior to the Penryn Core 2 Duo. In theory, it should be possible to get Sierra running on any Penryn or later Mac. It may be possible to swap out the Merom CPU in some Macs for a Penryn, which would then allow Sierra to run.

Sierra can run with 4 GB of system memory, but as with all recent versions of OS X, more memory will allow it to run even better.

Colin Mistr has published a macOS Sierra Patch Tool, which currently allows you to install and run macOS Sierra on the following officially unsupported hardware:

  • Early 2008 iMac or later
  • Mid 2009 MacBook (white) or later
  • Late 2008 MacBook Air or later
  • Early 2008 MacBook Pro or later
  • Late 2009 Mac mini or later
  • Early 2008 Mac Pro or later

Note: If you have the Early 2009 Mac Pro and have installed the firmware update patch so it identifies itself as MacPro5,1, you can run the standard installer. You do not need the patch tool.

You will need a USB drive 8 GB or larger and Mistr’s patch tool, which is linked on his page. WiFi does not function on these unsupported systems if they have the Broadcom BCM4321 WiFi module:

  • Late 2008 and Mid 2009 MacBook Air
  • Early 2008 and Mid 2008 MacBook Pro

The new Universal Clipboard lets you copy on one device and paste on another – whether it’s a Mac with Sierra or an iPhone or iPad with iOS 10.

Tabs are almost everywhere in Sierra, and they work much as they do in your browser. Third party apps will also be able to use tabs.

Apple Pay is now part of macOS, not just iOS.

If you have an Apple Watch, Auto Unlock will authenticate you and log you in automatically when you approach your Mac.

Optimized Storage can store infrequently used files in iCloud while keeping them immediately available any time you are online.


Apple developers can download an early pre-release version of macOS Sierra today, and a beta version will be available to users in July. The full release is scheduled for Fall 2016.
