When starting my Mac Os, I have on the screen an error like: panic(cpu 0 caller oxffffff80145d075a):'' Machine Check at oxffffff80145d8171, registers:\n" '"CRO: ox000000008001003b, CR2: 0x00000001000505b2,
I do not know what to do to solve this problem. Your help will be appreciated.
can you post another 10 lines of that panic report?
the hexadecimal numbers are not important for this purpose, no need to transcribe them.
or can you can you post an iPhone photo instead?
especially if there is a line with "panic-reason"
Machine-check is a serious hardware issue.
one common issue with these Macs is the they have error-correcting code RAM memory. This sometimes causes machine checks, but there is much more to the story.
Dear Bennet-AIder, thank you very much for your responses and questions.
I do not have any reason. The main message before the panic error is 'your computer was shut down because of a problem', then from time to time it shuts down and restarts twice after I use my password and started using an application.
Kernel Panic Reports are stored in the Folder at:
/Library/Logs/DiagnosticReports
If you copy and paste that string into:
Finder > Go menu > Go to Folder
it will take you to the Folder where those reports are stored.
Kernel panic reports are named with Date&Time and start or end in ‘panic’
If you find one, please post as much as you can here, by using the “additional text” Icon in the reply footer (looks like a paper with writing). (Once the report devolves into incessant software-names or incessant Base-64 dumps with lots of AAAAAA lines, you are done.)
Please don’t post more about 20 lines of any other types of reports — they are interminable, and any information useful for this purpose is on the first screenful.
If you post your kernel panic here in its entirety, using the additional text icon in the reply footer, we do have some Readers (typically with developer background) who can attempt to interpret those panic reports. Even if no clear symptom emerges, this can still save a step if you DO need to contact Apple support later, because Apple Support specialists can read the panic reports you posted here, if you tell them what discussion or what Avatar.
Dear Grant Bennet-Alder,
Thank you very much for your prompt responses and suggestions.
Unfortunately for me, I am unable to open my computer as it gets stucked before start up is completed or it restarts then stops displaying a panic message.
This to say that I do not have access to the reports you mention in your last message.
I do not know how to proceed. I really need your precious help.
Best regards
