High Sierra 10.13.6 Loop Booting

[02R96]

I have a Mid 2011 Mac Mini with 2.7Mhz Processor, 8GB of Ram & an AMD Radeon 256 running dual displays. Ever since I upgraded to 10.13.6 it takes around 5-7 attempts for my Mini to finally boot. Each time it gets a little bit further on the apple progress bar then reboots until it finally gets what it needs, then correctly loads the desktop, apps etc. after logging in. It works perfect!

I've tried all of the quick answer fixes but nothing resolves it. Is this something I have to live with until the next rev or has someone discovered the root cause of the rebooting.

I don't know what the quick answer fixes are...
Have you tried Safe Boot? https://support.apple.com/en-us/HT201262
You may need to redownload, make a USB installer, and try over.

By quick fixes I meant reset the NVRAM, run the Disk Utilities, etc. I don't believe I tried "Safe Mode". I'll give it a try. The link has some good technical infor too. Thanks.

I rely on my little Mac so much. A firmware update worries me, and I'm a former IT Admin. I run Time Machine so I have backup. Is there a way to check the version?

Did you try to get the info from the Apple icon menu on the left of the title bar going down to "About this Mac" ?

Boot ROM Version = your firmware version.

If you are a terminal person, you can also try this command line:

"system_profiler SPHardwareDataType"

Besides Boot ROM Version, it will list model, processor, speed,SMC version and others.

Hello. Sorry for not replying to everyone's posts. Family matters...

Anyway, Boot ROM Ver: 130.0.0.0.0

Wild guess, maybe some hardware failure?

My old MBP gave up the ghost re: the GPU. Similar symptoms. Managed to get it to boot and dig through the logfiles: GPU errors all over the place.

Can you boot into recovery? If so, dig through the log files. If can't boot recovery, disk or some other hardware issue might be a problem (aside: one reason to keep a bootable USB stick or bootable clone around: if that does not boot, got some big hardware issues going on).

I don't think it's a hardware failure as this started after the last update (for High Sierra), Apple pushed out.
