The fourth-generation MacBook Pro (2019) is the final model that can be downgraded from macOS Catalina 10.15 to macOS Mojave 10.14; 2020 models cannot. Mojave is the final MacOS operating system to support 32-bit applications such as Microsoft Office for Mac 2011. If you have a machine with one of these GPUs installed, I'd advise upgrading it if possible (can be done in 2010/2011 iMacs, iMac11,x-12,x), disabling the dedicated GPU if using a 2011 15' or 17' MacBook Pro (MacBookPro8,2/8,3, instructions to do so can be found here), or not installing Catalina. Running Catalina without full graphics.
UpdatesThe MacBook Pro 'Core i7' 2.0 15-Inch (Early 2011/Thunderbolt) features a 32 nm 'Sandy Bridge' 2.0 GHz Intel 'Core i7' processor (2635QM), with four independent processor 'cores' on a single silicon chip, a 6 MB shared level 3 cache, 4 GB of 1333 MHz DDR3 SDRAM (PC3-10600) installed in pairs (two 2 GB modules), a 500 GB Serial ATA (5400 RPM. To disable the AMD GPU on a 2011 MacBook Pro 8,2 or 8,3, follow the guide found here. Built-in iSight cameras: Currently, built-in iSight cameras do not work correctly on some machines. It seems to be hit or miss, but when installing, expect your iSight camera to be non-functional.
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 Mojave Macbook Pro Early 2011
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.
