mac Pro mid 2010 only cycles between problem screen:
"your computer restarted because of a problem..."
and the progress screen which is stuck at 80%
loaded. No other choices, ie mac is useless.
Restarts not working.
wont open in Safe mode, wont show alternate
system disks in option start either
I even took out the "upgraded" disk and
still nothing will register. grrrr
At this point I would take it in for service. If it is a MacBook Pro (Mid 2010) the product would be listed as vintage. See Vintage and obsolete products - Apple Support for more information. Essentially you need to find an Apple Authorized Service Provider in the area willing to look at it.
This actually reminds me of a poorly installed firmware update.
Don't install the firmware, without making sure the CMOS battery (different from the battery that is used when the computer is not plugged into power), is replaced.
Once it is replaced, then apply the firmware update.
Now are we talking a MacBook Pro notebook, or a MacPro desktop machine?

My mid2010 MacPro is completely useless now
firmware? battery? Suddenly the moment I upgrade to HIGH SIERRA MY FIRmWARE WENT WRONG AND MY BATTERY FAILED? caps lok error
the issue IS updating to hi sierra.
Finally got to cmd-R and then the
update option twirled for hours
to no effect. Tried to restore
from time machine but it
wouldn't see time machine.
Try to install OS and it only gives me
Hi Sierra option, then cant go back.
Make sure run first aid with disk utility in the recovery mode. Also if you have to erase the disk. Then attempt to reinstall the macOS.
Otherwise try contacting Apple support they might be able to send out a disk (there might be cost), so you can try installing macOS 10.6.
OK cmd-R > first aid:
"cant repair volume because other
APFS volumes in its container are mounted..."
even tho it has been erased.
Is there a way to access other volumes with on OS ON THEM?
also there is a disk image called OSX base system.
Is that the new Hi Sierra trying to be present.
Neither of these volumes has "restore" available.
now what?
removed the offending start up drive altogether.
The back up drive worked and computer is running.
Put the offending drive in my USB 3 pci card, and
was somehow able to reformat and then cloned the
back up drive to this reformatted erstwhile start up
drive. System prefs recognized the cloned drive as
a legitimate system drive. Great, ready to go.
Restart shows grey screen and NO start up
commands work - nothing. Took out all drives
except the back up drive that worked before -
NOTHING. Completely lost again. grrrr
anyone?
Haven't had an install disk since forever
omg now why do I get this:\
Will it boot from the install DVD for that Mac?
cmd R does not work too
ok Cmd R did work, but none of the subsequent menus work
ok thats cuz usb hub disabled
now select a back up is frozen
Did this issue start after update to the mac OS Serra?
computer consumes about 8 minutes on the hi sierra install,
then the apple loading bar appears and it wants another 34 minutes.
IN the past it eventually stalls. good night
My mid2010 MacPro is completely useless now
