2020 iMac rebooting after Sequoia 15.2 upgrade I upgraded my iMac to Sequoia 15.2 yesterday and now it reboots anywhere from 15-60 seconds after log in. I have turned off extensions, I have uninstalled unused applications, I have stopped unnecessary applications from starting up, I have ran health checks, and reinstalled Sequoia from recovery. I have had zero luck solving this problem. It works fine in safe mode. It does have boot camp and the Windows side works fine. This is the error code that I get: cpu 0 caller 0xfffffff00e67fce0 Any help would be much appreciated.

Architecture Error Dump (CPU: UNKNOWN, CPUID: 0x906EA) Hi good people :) My aging 2019 MacBook Pro is starting to show it's age, mainly with crashing at random intervals about once a month or so. Today I go the following error when it crashed when I tried to wake it from sleep mode: CPU Machine Check Architecture Error Dump (CPU: UNKNOWN, CPUID: 0x906EA) Core: 0 IA32_MC3_STATUS=0xBE00000000800400 IA32_MC3_CTL=0x0 IA32_MC3_ADDR=0xFFFFFF80171A738C IA32_MC3_MISC=0xFFFFFF80171A738C Core: 0 IA32_MC4_STATUS=0xBE00000000800400 IA32_MC4_CTL=0x0 IA32_MC4_ADDR=0xFFFFFF80171A738C IA32_MC4_MISC=0xFFFFFF80171A738C Core: 0 IA32_MC11_STATUS=0xEE0000000040110A IA32_MC11_CTL=0x0 IA32_MC11_ADDR=0xFF7ED0C0 IA32_MC11_MISC=0x7880000086 So it seems to be something wrong with core 0? if anyone could give any insight on the issue I'd greatly appreciate it. As mentioned earlier, it happens randomly, I have not used any new programs lately. I use the MacBook mainly for running windows VM via parallels to program Siemens and Schneider building automation systems.

Are you able to boot back into macOS with the OPT key on restart? If so, I would erase the partition with Boot Camp Assistant and then re-add it.
