Install macOS normally onto the desired volume. When the install completes, reboot back onto the installer drive. This time, open the 'macOS Post Install' application. In the application, select the Mac model you are using. The optimal patches will be selected for you based on the model you select.
Updates
Your machine will restart and you should now be able to boot from the Mac OS 9 For Unsupported G4’s CD from MacOS9Lives.com. Any data stored in the NVRAM will be erased if the machine loses power (e.g. The main power cable is disconnected from a wall outlet/power adapter, or has a flat battery. Before heading to Install macOS Catalina on Unsupported Mac, check out the unsupported collection of all Macs and if your Mac is from the unsupported list. Here are the list of unsupported Mac. Early-2008 or newer Mac Pro, iMac, or MacBook Pro. Aug 25, 2021 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. 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.
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.
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
Macos Unsupported Mac Os
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.
