Frage: MacBook Air stuck on boot
Hi, since yesterday my MacBook is stuck on boot: Before the login I just see a circular loading indicator and my mouse cursor is stuck in the top left corner. It seems like a service is restarting all the time since the loading indicator spins for like 10 seconds for disappearing and reappearing again. I tried resetting the NVRAM, first aid from the disk utility and reinstalling OS X - it all fails and so I'm still stuck. I also tried running languagesetup from the single user shell but this just returns an error message saying "file or folder not found". Im running OS X Sierra. Hoping someone has some advice since Im fearing only formatting can rescue my MacBook :( Cheers and thanks!
MacBook Air (13-inch, Early 2015), macOS Sierra (10.12.4)
