I have one similar to that 😃 I have set up a dual boot with EndeavourOS to get security updates there

(Prepare partition in macOS by shrinking main and make a second FAT. You’ll change the file system to the correct one during installation of Linux. At reboot hold alt/option to choose which OS/USB-Stick to boot)

With the macOS, I want to try legacy patcher, but would have to kill my Linux in the process, so I did not try it yet…
