My 2012 Mac Mini is experiencing random crashes. I've already run MemTest and the RAM appears to be good so my next step is to run the Apple Hardware Test. Unfortunately the partition with the AHT on it appears to have been deleted when I installed Ventura using OpenCore Legacy Patcher so holding D or Option-D on startup no longer works. On this page (https://github.com/upekkha/AppleHardwareTest) I found a way to make a bootable USB key with the AHT on it, but when I try to boot from it it shows a brief error that I can't read (I think it's saying that it can't load from a directory) and then reboots. My second idea was to copy the AHT files back to the System folder but that requires disabling SIP and when I boot to recovery mode and try to disable SIP (csrutil disable) it says the command is not found.
I'm at my wits end on how to do this. All I want is to run some diagnostics so I can try and figure out what's wrong with my system (it's not OCLP, I had crashes on officially supported OS's). If I can't get AHT restored, is there a free diagnostic tool that I try?
