Unable to upgrade to 11.2.2

I had the same problem with my MacMini. After downloading BigSur 11.2.2 a message appeared: "An error occurred preparing the update. Failed to prepare the software update. Please try again." The problem is (if installed) Kaspersky Internet Security.

I was unable to remove this app to prevent the blocking and was adviced by Kaspersky tech staff:

1. To resolve this issue quickly, we suggest you try to remove Kaspersky Internet Security for Mac by following steps shown in this article: https://support.kaspersky.com/14616#block1

*Note: if you are prompted for a password this is the same password as your Mac user account.

2. Once removed, please proceed to restart your device and update OSX Big Sur 11.2.1 version.

3. After Big Sur update complete, you may then download and install Kaspersky in accordance with our installation guide:

How to upgrade to macOS Big Sur

There are several points to consider before attempting the upgrade to Big Sur. The most important is Due Diligence on the part of the User and is a Prerequisite for a smooth upgrade

The below points should all be consider Before attempting the upgrade.

Point # 1 - Are there pre-existing Unresolved Software Issues. They should be resolved prior to upgrading - many will / may carryover to Big Sur making the system unstable / unusable.

Point # 2 - Are there any AntiVirus, Disk Cleaner, Optimizers, Defrag, VPNs etc installed which should be removed as per Developers Instructions. They are useless, unneeded, cause havoc and interfere with the normal operation of the OS. The Built-in Security of Big Sur is all that is required.

Point # 3 - What are the System Requirements ie: Empty Space Requirements specific to the Big Sur.

Point # 4 - Does the intended computer qualify for the upgrade.

Point # 5 - Is the existing System File System meet the file system requirements of Big Sur. Like Catalina - Big Sur requires the drive be formatted as APFS and does not automatically convert HFS Journaled to APFS.

Point # 6 - Are the installed Applications / Extensions compatible with Big Sur. Check with the Developer for compatible Apps / extension or do they offer updates. Same goes for Third Party Drivers for Printer, Scanners etc.

Point # 7 - Do I have a Rescue Plan In-Place. This comprises having a Time Machine Backup and for addition purposes - two Tested Bootable Clones each to separate external drives. This is insurance incase the upgrades goes sideways

Point # 8  - to upgrade to Big Sur will require a quick, stable and reliable Internet Connection - preferred method is via Ethernet Connection. If not available and using Wifi - move computer as close to the Access Point / Router and disconnect all other devices connected to Wifi. Want the maximum bandwidth for the computer being upgraded to Big Sur.

Good Luck and come back to these Forums if there are questions, concerns or comments.
