Strange MacBook Pro 2015 boot issue
has anyone ever run into an issue where your MacBook Pro has a very slow boot progress bar, and ends up with a message “macos could not be installed on your computer” upon power up. This has happened twice now for no apparent reason. After a short delay it dumps and installation log, and goes into a mode where I can access some utilities like disk utility, etc. One of the options is to choose a startup disk, and after pointing to my internal drive, the next boot up works like a champ. I’m trying to narrow down how I get into this mode in the first place, as I am NOT booting into recovery mode (by hitting option R) after hitting power button. I’ve already been to Genius Bar last month(no help from them) and now a call to technical adviser at apple. They had me reinstall the OS.
Anyone ever see this behavior? It’s like the startup disk info in the SMC and or PRAM is getting trashed for some reason. So the machine randomly doesn’t know what the startup disk is.. the question is if this is true, what could be clobbering the SMC.
ITS SCARY TO GET A SCREEN LIKE THIS WHEN TOU DONT ASK FOR IT, PHOTOS ATTACHED.
