Error Message Startup MacOS Ventura 13.5 I always, starting up my iMac Pro, become the error message 'You shut down your computer because of a problem' while this is not true. Before I shut down my computer properly I always close all programs. But the next time I start up I become, again and again, the same error message while there are no applications running at all, not in the front, not in the back (I cleared the complete launch list). Anyone recognized this problem ? What more can I do ?

Error code '-1008F' during Internet Recovery (Mac Mini 2018) Hello Community! I deleted the partitions on my Mac Mini 2018 HDD. And I've been trying to get Mac OS installed again. My starting point is to power on and hit Option + R to trigger Internet Recovery. The problem is that during Internet Recovery, I see this on the screen eventually: An earth icon with an exclamation point. The message: "support.apple.com/mac/startup -1008F" I don't know how to proceed from here: Is it still possible for me to get Mac OS installed on my own. If so, please tell me how. Thanks very much in advance, Emil Belardo

com.apple.buildinfo.preflight.error error 21 on iMac in Recovery Mode reinstalling Mac OS Monterey I'm trying the reinstall Mac OS Monterey 12.6.7 through recovery. I get this error "com.apple.buildinfo.preflight.error error 21". Does this error have something to do with my wifi and firewall in my cable modem. I did check the drive with first aid, and everything is fine there. Just trying to reinstall the Mac OS through recovery mode. Any suggestions?

Hi,

It seems to me, your iMac Pro has network related issue. If you have another Mac, you can create bootable USB memory stick macOS installer.

Actually the Ethernet cable did the trick. Not sure why wifi would not. Thanks
