freezing on login screen
Hello, today 2 times my mac freeze on login screen, nothing i can do except manual reboot. It happend few times previously but what worry me is that it seems its more often now, so i am backing up files for any case. Is there anything i can do about this and is it possible to resolve problem and make sure it wont happen again? or i have to visit apple service..
Honestly i not belive this happening to a such expensive and quality product. 2 years never any big problems now with high sierra its like another computer..
MacBook Pro with Retina display, macOS High Sierra (10.13.3)
