      I am really at my wits end here. I am hoping someone on here with more experience with UEFI and boot loaders might be able to provide insight into an otherwise inexplicable problem I am having with a brand-new system built around the ASUS TUF Gaming X570-PLUS. My gut tells me the problem is somehow related to UEFI settings, Secure boot, or some combination, but I really have no idea if that is the case.
       
      The problem is two-fold. First, my system will only boot to a device (e.g., USB stick) under two conditions: 1) no SATA drive is plugged in or 2) when a specific SSD is plugged in (I'll refer to this as SSD1). I have three other hard drives that otherwise work (I have tested them in another system). None of them have Windows installed, though some do have existing data partitions. One of the three is a brand-new, never-been-used 1TB SSD. If I plug in any of these three other hard drives, the system will reboot immediately after POST. However, if SSD1 is plugged in it will boot to a USB stick - UEFI or Legacy, doesn't matter.
       
      Secondly, if I attempt to create a partition, run a surface test, or install an OS to SSD1, the system immediately reboots. I can format SSD1, change volume sizes, run a surface scan, but only in a live linux environment - if I plug SSD1 into another machine as a secondary data drive (i.e., I boot to my primary boot volume), the other machine will blue screen when loading into Windows. If it is attached to this new machine, it will boot to a USB stick just fine.
       
      I have also enabled Hot Plug, which allows me to access SATA drives that I plug in after boot. If I hot plug the brand-new 1TB SSD during a live linux distro, the drive shows up and I can see its properties. However, if I try to do something like create a partition or run a surface test, the machine will also immediately reboot.
       
      Does anyone have any idea as to what might cause this? The only thing that I can think of that explains both problems is some kind of secure boot-like security feature, but I haven't been able to figure out how to confirm whether that is the case. In 20 years of building computers I have never even heard of anything like this. I am new to EFI systems, however, so I'm quite out of my element - this is the first EFI-based system I've set up.

      After hearing that OpenCore is so much better than Clover, and that it will probably be able to boot Big Sur before Clover does, I decided to take the jump.
       
      Running Catalina 10.15.5 18F101 with OC 0.5.9.
       
      So far I like the result. The OS feels faster, boots faster.
      And absolutely everything works (sleep, network, etc...)
       
      So, that's it? Is there anything else I have to do?

      How to Add APPLE RTC PATCH

      I converted boot from Clover to OC 0.5.8. Everything is fine. I even solved few sleep/wake problems I have.
       
      I use Catalina disk as a primary boot. OC kicks in regardless whether I use windows or OSX. Every time boot occurs I get this file in the EFI partition. It is supposed to show boot errors, missing drivers, etc.
      In my case I cannot figure out why it shows every time. 
       
      Please, take a look. maybe you can at least decipher it and send me in the right direction. Oh, yeah: SIP is at 0x67
      Thanks in advance

      I'm trying to upgrade from Sierra to High Sierra. My Sierra is working and booting great with the latest Clover 5.0 r5115, but when trying to upgrade to High Sierra, any time the computer reboots into the installer, it gets stuck at the line "Start ReadKernelCache". The screenshot is attached. I've tried the following troubleshooting steps that I've read in other similar posts, none of which worked. It always remains stuck at that line:
       
      Boot with UseKernelCache=No and/or -x and or -f Temporarily remove discrete graphics card and try to install with integrated graphics Add MATS to the Drop Tables list in Clover Configurator Look for an option similar to "Above 4G Encoding". My motherboard doesn't seem to have that. Try a bootable USB drive with the High Sierra installer instead of the App Store mechanism. The USB boots great, and I can initiate the installation, but upon reboot, I get the same issue trying to boot into the installer.   Disable integrated graphics in the motherboard's BIOS    
      Below are my system details. It seems like it should be possible, based on this post, to run High Sierra with this motherboard and CPU, but I can't get the installer to run. 
      Thanks for any help!
       
      Motherboard: Gigabyte GA-Z77X-UP5-TH
      CPU: Intel Core i7-3770K
      Graphics: EVGA GeForce GTX 970 
      Clover: 5.0 r5115 with basically no mods from the default ISO aside from enabling APFS driver
