Problems installing Big Sur 11.2 update

Hi,

For the past few days I have been trying to install the Big Sur 11.2 update, however, it keeps crashing.

It downloads then goes to the the 15 minutes left to prepare the update finally moves to 10 minutes left to prepare then errors out. The error is: download failed. An error occurred while downloading.

I have tried a whole bunch of different attempts. WiFi, Ethernet to the router, tried installing with a backup user to no avail.

I am using a 2019 16 inch MacBook Pro.

Any suggestions appreciated.

Boot into Safe Mode by booting with the Shift key held down and check there to see if the problem persists. Reboot normally and test again.

NOTE: Safe Mode boot can take up to 10 minutes as it's doing the following;

• Verifies your startup disk and attempts to repair directory issues, if needed

• Loads only required kernel extensions (prevents 3rd party kernel/extensions from loading)

• Prevents Startup Items and Login Items from opening automatically

• Disables user-installed fonts

• Deletes font caches, kernel cache, and other system cache files

Are you on a M1 Mac?

Are you using a bluetooth keyboard?

Nope. But I have very little experience with use of the safe mode, apparently so does my Mac.

Apple should bring back dmg file for little update. Safe download. It such a headache to update. If mac wont boot then, boom.

The same for me with a brand new air. Installing big sur 12.2.1 is boggy. Even though i got 12.2 installed without any trouble. What a mess these updates.
