I see your computer has 16GB of RAM, was the computer purchased with 16GB or was it upgraded? Also, what brand of RAM was purchased (assuming you upgraded it yourself) and where was it purchased from. The most common hardware causes are RAM related and failing hard drives. I don't see any of the normal software indications so that leads me to believe the KP's are caused by hardware. I see a couple of things, the computer is definitely suffering from Kernel Panics which may be caused by either hardware or software. In my case I had Catalina installed by earlier version of Sierra installed. It takes nearly 30-40 minutes to reinstall the earlier version of Mac OS. Pressing Option+Command+R doesn’t work so I reinstalled the earlier OS by pressing Shift+Option+Command+R and then Start button. Try this, I was also getting the same 5101F error. And of course, no access to Recovery partition. From there I could manually update to Big Sur 11.1 but the firmware version stays the same. 180 firmware and when I trigger IR it doesn’t error out anymore, but the latest OS it could go up by IR is Catalina. After a longer than usual update and many more restarts that took about 3 hours total, my Boot ROM version was updated to 424 and the problem was solved.ĮDIT: I got another one with ver. Then I went to App Store and updated to Big Sur. So how I solved this was pretty time consuming, but it worked! I used Shift Cmd Opt R to get Yosemite back on the SSD. I bought this Mac with no SSD and put in an SSD with Catalina pre installed, so the BIOS was probably not updated. My speculation is macOS has something similar to a compatibility mode so it could run on older BIOS versions but couldn’t boot from the Recovery Partition, especially Big Sur. (To check it, go to the Apple logo - About My Mac- System Report - Hardware and see the number of Boot ROM version)Īnd that was right! I have two other MBPs and the Boot ROM versions were 428 for the 2014 and 424 for the 2015. So, according to the articles, I have an incompatible Boot ROM version (or commonly known as BIOS).

This has been a very frustrating issue for me, I actually stopped using this computer in 2020 but after a need arose I plugged it back in with the hopes it would work again and it did! And it worked perfectly, for a couple of weeks. Also, occasionally when the computer crashes it won't boot back up again, the boot starts but the bar gets stuck at around 25% or sometimes 70%. Sometimes it won't happen for weeks but eventually, the screen will start to glitch again. Sometimes the screen will glitch and then recover and be okay. I find I can't replicate the issue on purpose. This happens fairly often, maybe once or twice in a session even whilst using fairly low-demand applications such as Chrome, Word and Teams. My iMac screen will glitch out and the computer will crash. Hi, I've had this problem for years and have searched for a fix but can't seem to find the cause of this issue.
