Does this mean you were actually able to boot into Safe Mode?
If so, then run the third party app EtreCheck and post the complete report here so we can examine it for clues. This will also provide us with the exact model and current version of macOS among other things.

Otherwise to get the exact model of the Mac, enter the system serial number on the check coverage page here (Please do not post the serial number on the forum since it is considered personal information):

What version of macOS were you using before the "update" and what was the version of the update you were installing?
