Dear Mac friends! I have a late 2012 imac. It recently crashed compleatly and would not boot agen. Tried deleting OS and do a recovery, but none of the install options work like boot from usb, recovery by internett or safemode etc. I figured it was a HDD issue, and bought a new SSD and swaped the old one (phu, what a job). I also changed the Ram while at it. (Way nice job:)

However, i still have the same issue: it freze during install/boot, both from usb boot and both recovery options. i have tried every startup key combination there is, nothing gets me forward.

Running diagnostic it tells me all is well with hardware. Im pretty handy with mac, but now im at a loss of options for what to do. Any suggestions?

Running it in verbose mode it stops at something with apfs rebuild?

and in when i tried booting it from usb in Linux hoping i could get somewhere there it stops at acpi error .. same with Elementery OS.

Anyone have any suggestions on where to go from here??

Apple MacBook Pro "Core i7" 2.5 15" Mid-2015 (DG) Specs Model# A1398 I have been IT tech for 30 years and work as an instructor at the local college. I worked for the school system before that for 15 years so I have a good handle on many apple fixes and work runarounds. But this one has stumped me. So I made up the USB of El Capitan and the Yosemite. Both do the same and boot to a certain stage and hang with the spinning apple logo but hang. After that if I leave it the computer goes to blank screen and hangs. I have also tried to recover from the internet via restore but stops right after it loads to the apple and hangs. I even changed the DNS on the Wi-Fi to Google encase it was a country issue. Funny thing is I can load Windows 10 edu from a external DVD and everything works but the video drivers and HDMI. I never seen this and next step is to try to make a DVD out of a Yosemite 10.10 and try to load that. Anyone ever seen this one before?

I was also thinking about Target mode it to my older 10.6 mac mini and use the disk utilities to restore the OS. I think I need a new type of Firewire from old to new.
