Hi everyone, first time here! As of yesterday my macpro sometimes wont boot. When it does boot i can get to the login screen, i type in my password, the loading bar gets halfway there and my mac shuts down. It’s really weird, i always hear the startup chime, but sometimes i get a screen, sometimes i dont.. One hour ago i got into my computer, i ran disk utility, ccleaner but no errors or whatsoever.. Now i got to the login screen twice but couldnt login! Anyone? Thanks!
Try logging in using an external keyboard. That failing take it in to an ASP and request they run this test: https://www.apple.com/support/macbookpro…
