system takes 120 gb on a 250 gb 2016 MacBook
hi , I have a problem on a new touchbar MacBook, that the system takes 120gb!! as all I have is 250 gb , it really a big issue. why would an OS take so much space anyway? please what do I do? tried to google it but don't seem to find any real solution. thanks in advance
I have latest Sierra
tried to run macbooster and clean my Mac, they cleaned only around 2gb.
MacBook Pro TouchBar and Touch ID, macOS Sierra (10.12.4)
