I'm trying to update my MacBook Pro 13 (2018) from macOS Big Sur 11.0.1 to 11.2.1.
Each and every time I try to update it, the system downloads the update and then displays this error.
I tried rebooting into safe mode but no luck.
Does anybody know any tip or trick for this?
MacBook Pro 13″, macOS 11.0
Suggest following @jeffreythefrog posting.
If that does not function - Restarting Recovery Mode - Command + r - immediately at startup. Various option presented >> Reinstall macOS. It should download the latest version macOS Big Sur 11.2.1
since the message says "check internet connection", and you also tried safe mode to no avail, i'm guessing you are trying to download it using wi-fi. if that is the case, i would recommend connecting the mac to your router with a wired ethernet connection. sometimes downloading OS updates/upgrades over wi-fi can cause the download to become corrupted, or not complete at all.
should I need to backup or backup is not required and is this process safe?
Due diligence is always a requirement - Time Machine Backup Before attempting.
