It is better than macOS 10.15, Catalina, due to its powerful improvement and new features. However, Apple dropped various Mac versions, making installation of macOS 11 on unsupported Macs almost impossible. In this article, you will learn about the compatible devices and how to install macOS 11 on older Mac or unsupported devices. So I began to search. And was I reassured by the dozens of Mac-afficionados already running the macOS Big Sur beta1 on their unsupported MacBooks and Mac Minis. Well then, with all those people already installing the beta on their unsupported Macs, I started to work on it for mine. But I would rather buy a second generation silicon mac to truly take advantage of the new OS features and remain on Catalina (or HS) for everything else. Or just bootcamp your old unsupported mac to windows 10 as the main OS and macOS as secondary to bring out some of its latent potential to 2021. I could not get it to properly install on imac 9,1. A: If your Mac had official support in macOS Catalina, it will be able to be patched to run Big Sur with minimal issues. If your Mac was unsupported before the release of macOS Catalina, support remains to be seen as graphics acceleration may not be feasible (as before with Mojave and Catalina) at this time.

This article will help you install macOS High Sierra 10.13.x on your Mac with macOS High Sierra Patcher. The article will be useful to owners of outdated Mac models but quite workable today.
Also, Mac models’ owners officially supported by the macOS High Sierra operating system may face the fact that installing the system imposes a new APFS file system, which may be undesirable for the user for various reasons. For example, some owners of Mac Pro 5.1 or Mac Pro 4.1 models installing macOS High Sierra 10.13.6 (the last build) can install the operating system on the Mac OS Extended (logging) section and not apply Patch.

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.
Install macOS High Sierra on unsupported Mac: What you’ll need?

How to install macOS High Sierra on unsupported Mac? 5 Easy Steps with Patch file
Install Macos On Incompatible Mac
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.
Update:
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.
