That means when I need access to a bootscreen, I have to take out my RX580 and insert my GT120, and when I'm finished I'll have to do it all in reverse. I'm also unable to use my stock GT120 in combination with my RX580 for some stupid reason, when they're both in the machine neither of them work.

Is there a 'safe' way of installing Catalina on my 4,1(5,1) without using the DosDude1 patcher? I'm kinda tired of updating the OS by completely reinstalling a new copy of Catalina every time, even though it works. So my question is, how do I get a working recovery partition. I attempted booting into recovery via a bootable USB, and this worked but gave me no rights to change anything whatsoever. I can see my main drive being partitioned into 5 partitions, and one of them being the recovery, but there is absolutely no way I'm able to access the recovery partition. Though recently I tried to disable SIP via the recovery partition (was unnecessary because using DosDude1's patcher automatically disables SIP) and found out that my recovery partition was non-existent. And quite likely Apple will change things again with the M1X/M2 models and Monterey.I've got Catalina running on my 4,1(5,1) for a few months now, and has been working without much trouble.

Maybe you need to connect it to another Mac and treat it like an iOS device instead. How to Boot with macOS Catalina USB Install Drive To boot from the MacOS Catalina boot disk, connect it to a Mac, then reboot the computer and hold down the OPTION key to boot into the boot menu, where you will be able to choose the MacOS Catalina installer drive as a boot option. Maybe you can do that if the Mac is moderately new, but not too new, and someone has changed the default settings to be less secure. Now, maybe you can still do that if the Mac is old enough. Used to be follow a couple easy steps to make a bootable drive, plug it into another Mac, hold down option key, and you're off to the races. Now they need to know whether that device is a classic Intel Mac, a T1, a T2, or an M1, and treat each of them differently.

Sed -i s/T1/T2/g find the current matrix of scenarios how to boot or install one macOS based on the existing state of the device to be frustrating to deal with myself and utterly inscrutable to Windows-centric technicians who have been told (and used to learn) 'Macs are so simple there's nothing really you can do to mess them up.' Now it is quite easy to get a Mac into an unbootable state that necessitates a long slow internet recovery.
