Updates

MacOS Sierra (version 10.12) is the thirteenth major release of macOS (formerly known as OS X and Mac OS X), Apple Inc.' S desktop and server operating system for Macintosh computers. The name 'macOS' stems from the intention to uniform the operating system's name with that of iOS, watchOS and tvOS. Sierra is named after the Sierra Nevada mountain range in California and Nevada.

Before going to upgrade there are two important points that you should know about that, the first one checks your Wifi compatibility, because some of Mac have Wifi which is unsupported in the macOS Mojave. Attempting to install Catalina on an unsupported Mac is in no way supported by Apple, and you are doing so at your own risk. MacRumors cannot be held liable for any data loss or damage as a result. I did this by using a supported Mac to install Sierra. Nothing odd here. Then, I downloaded @parrotgeek1 's ZIP (attached to my post) and ran it on the drive with Sierra installed on it. You should just be able to plug the drive into an unsupported Mac and use Option+boot or Startup Disk to boot from it.

Important Notes:

Using APFS is REQUIRED in Mojave in order to receive system updates via the normal Software Update method. If you choose to continue using macOS Extended (Journaled) as your filesystem type, you will NOT receive System Updates via System Preferences. If you are not using APFS, you can follow the 10.14.1 installation steps below.

After applying ANY system update via Software Update, re-applying post-install patches using your Mojave Patcher installer volume will most likely be necessary. If you install a software update and the system fails to boot afterwards, this is what needs to be done.

How to install os sierra on unsupported mac

10.14.6

10.14.6 can be updated normally via Software Update if using an APFS volume, and will need to be patched using an installer volume created with Mojave Patcher version 1.3.2 or later after installing.

10.14.5

10.14.5 can be updated normally via Software Update if using an APFS volume, and will need to be patched using an installer volume created with Mojave Patcher version 1.3.1 or later after installing.

10.14.4

10.14.4 adds new changes that ARE NOT patchable by the post-install tool of Mojave Patcher v1.2.3 and older! Before updating to 10.14.4, you you will need to use the latest Mojave Patcher version to create a new installer volume, using the 10.14.4 installer app. Then, update to 10.14.4, either by installing via Software Update, or by just using the installer volume you've created to install.

10.14.3

If you are currently running 10.14.1 or 10.14.2, you can simply use the Software Update pane of System Preferences (if using APFS) to apply the 10.14.3 update. Once the update is installed, you will most likely need to re-apply post-install patches to get the system to boot again. This process is detailed in steps 8 - 10 above. If you are currently running 10.14.0, you'll need to proceed with the 10.14.1 update method described below.

10.14.2

If you are currently running 10.14.1, you can simply use the Software Update pane of System Preferences (if using APFS) to apply the 10.14.2 update. Once the update is installed, you will most likely need to re-apply post-install patches to get the system to boot again. This process is detailed in steps 8 - 10 above. If you are currently running 10.14.0, or are using a non-AFPS volume, you'll need to proceed with the 10.14.1 update method described below.

10.14.1/macOS Extended (Journaled) volumes

The Mojave 10.14.1 update does NOT install properly on unsupported machines, and could result in an unbootable OS. If you want to install the 10.14.1 update (and are not currently running 10.14.1), perform the following steps:
• Download the latest version of Mojave Patcher
• Download the installer using the Tools menu of Mojave Patcher
• Create a patched USB installer
• Boot from that, and install 10.14.1 onto the volume containing an older release.
• Once done, apply the post-install patches, and you should now be on 10.14.1.

With each new OS version, Apple eliminates support for older hardware, even if it's still capable of running the new OS.

Planned obsolescence or just a push for you to make an upgrade? It doesn't matter, actually, as there are still ways to use the newest OS on older Apple computers, such as:

Early-2008 (or newer) Mac Pro, iMac, or MacBook ProLate-2009 (or newer) MacBook Air or unibody MacBookEarly-2009 (or newer) Mac Mini or white MacBook

4. When the creation of the tool is finished, reboot the computer, keep ALT/OPT key pressed, and select the USB device on boot.

5. Install MacOS as usual and wait for the process to finish.It will restart, but will not work, so you need to repeat the step 4 and boot from the USB drive, to run post installation tweaks.

In the first interface after boot, select from the top menu: Utilities - MacOS Post Install

Now, you must select the correct Model Identifier for your hardware (see Step 1) and apply the suggested tweaks and reboot!
