Blue screen

[and 4096 others like this]

Hi,

I had a blue screen on Mac Mini (well, on display, but I assumed Mac Mini may cause this). I read that it may be a problem with display or other hardware attached to Mac, but it can be Mac itself as well.

There was never any issue with display, and I bought used Mac week ago (it was first and only blue screen). Are there any tools to check if Mac hardware is ok? Maybe event log service?

You can try to run diagnostics. Shutdown the Mini. Restart, holding down the "D" key. Whether this works and whether you get Apple Diagnostics or the Apple Hardware Test depends on your Mini model.

For logs, open the Console app (in /Applications/Utilities). This is going to vary depending on the OS you have. But for the recent OS's, look under "System Reports" and "User Reports". See if you have a file that starts with "Kernel_" and ends with ".panic". Or look for a file that ends with ".crash", ".gpuRestart", ".hang", or anything else that sounds bad. Don't worry about the ".diag" files - usually they're not important. If you have any of these files (other than .diag), see if you can find one with the timestamp which corresponds with your blue screen. You can post that here, along with the filename, but I find that any thing but the kernel panic log won't tell you much other what where the problem occurred. If there's nothing that turns up, you can try a separate memory testing program. After that, it can be an extended process to try to figure out what went wrong, if it's a rare occurrence or something to be worried about. Although if it's a recently purchased used computer, the suspicious part of me says that could be trouble.

Hi again!
Thank you for advices! I wasn't able to do all test sooner, sorry for that. I run Apple Diagnostic Tool and it shows 0 problems (code: ADP000). I also checked "System reports" but all files end with ".diag" so as you said, I assume it's ok? In "User reports" there is no file.

So maybe this Blue Screen was only some kind of software mistake? I run Sierra, I didn't update it to High Sierra, cause I will change HDD to SSD in a few days. When the Blue screen occurred, I was watching VOD movie in Safari. What do you think about that?

Oh, and the time strap... Well there is like 1000 lines in a time frame when Blue Screen shows up :-( but only in sysLog. I don't know what I have to looking for, but didn't found anything sounds wrong.

Anyone know other reasons that may cause blue screen? :-(
