an error occurred while updating or installing macOS
It says "The request timed out"...
I tried it several times and I shut down and restarted my computer.
Still doesn't work.
Who can help?
MacBook Air 13″, macOS 10.14
Question marked as
Are you using an antivirus?
A VPN?
If you do disable and try again.
Next try rebooting your router and modem.
