MacBook air 2020 isn’t responding
I turned my MacBook Air 2020 off during update and now I’m not able to turn it on . So, what should I do?
MacBook Air
Turn on you mean power it at all or it powers but it doesn't boot?
Reset SMC https://support.apple.com/en-us/HT201295
Reset NVRAM https://support.apple.com/en-us/HT204063
It it turns on after that, start in Safe Mode by turning it on and holding Shift key.
You can also try reinstalling macOS https://support.apple.com/en-us/HT204904
If it doesn't solve your problem, once you're still under warranty, you better get in touch with Apple for diagnostic and proper solution.
