Install macOS Sequoia on unsupported models

In this video, I'll explain how to install macOS Sequoia on older, unsupported, Apple Mac models. This could be a fresh install, upgrade or dual boot. We will do this using OpenCore Legacy Patcher. For this video, I'll be using an Mac Mini Late 2014 but this method should work as well for Mac Pro's, MacBooks and different models of iMacs as well that are unsupported.

We'll start with an introduction, prepare the required USB drive, install macOS Sequoia, check the patches and take a quick look at some of the new features.

Nice. I’ve got a maxed out Mac mini 7, 1. Going to use it as my work computer. This update has made it faster and usable for office related tasks

Thanks for showing how to set up dual boot to keep the original MacOS while also installing the unsupported MacOS in a different partition

Thank you!!! Just installed macOS Monterey using this video and the one on Monterey from 2 years ago. My Late 2009 iMac 21.5 inch upgraded with SSD & max RAM is now smoothly running 🙂🙂 Did not want to push to Sequoia just yet. Will attempt do install dual boot to WINDOWS10 soon using your other vid. Greetings from the Netherlands!

Great videos - thanks. Question on Software Updates, As Sequoia goes to 15.2, 15.3 etc, could you please make a video on how to upgrade our systems? Can we simply go through Software Update?

The iPhones that can run 17 are supported for 18, and the Macs that can run 14 (Sonoma) are supported for 15 (Sequoia), except for the 2 MacBook Airs you mentioned. watchOS, however, has dropped support for the Apple Watch Series 4.

Hi. Just to understand... I tried many times to do a clean install on my mid 2012 13" Macbook Pro (i7 2.9, 16 GB RAM and 512 SSD). All proceeds smoothly until I choose the disk for the installation. It seems to be stuck. The third time I let it working for almost 6 hours without knowing if it was working or not. No spinning wheel or progress bar. When I decided to stop, I had to recovery from backup because a message of missing disk appeared. I redownloaded everything, I recreated the Mac Installer without any problem. Now it's stuck again. Any idea? Looking forward to hear back from you (and sorry for my english if it's not clear...). Thanks!

I have a Mac mini late 2014, I updated it to Sequoia oclp 2.2.0 and I feel that it is slow. The animated wallpaper is also very slow. I hope you can help me very much.

Hey mate, is there any features lost when doing this on unsupported hardware? Also can you sign into your apple account with this?

Sequoia 15.1 runs on my MacBook Pro Mid 2009 a bit slowly but it works. Problem is - the Music application keeps crashing :-( Can't you find any solution for this?
It would be great to give to the old mac a little more life :-)

why the 2019 MacBook Air isn't supported even with OpenCore?

[donelson]

Do I have to build an installer, or can I just upgrade to Sonoma?

Every time I get to the part where it says create macOS installer, it starts to download for a few minutes and then it says error on a 2014 Mac mini, anybody have any suggestions?
