Can't update OS to CATALINA
I can't update OS to CATALINA from MOJAVE. The app store told me while downloading as the requested time out. What can I do?
MacBook Air 13″, macOS 10.12
Connect your mac to your router via cable if you can.
If you can only use WiFi then move your mac as close as possible to your router.
Do not use the mac while it is downloading or any other devices that share the
same internet connection.
