Ventura 13.0.1 Failed to prepare the software update. Please try again.

I tried to install Ventura 13.0.1 and I get this message.

I have tired to install via wifi only, via network cat 5 only and via safe mode.


Any other suggestions?

MacBook Pro 13″, macOS 13.0

All fixed. Followed these instructions (Ventura 13.1 Failed to Prepare Update - Apple Community) to reset the NVRAM on my MacBook Pro and the update worked as expected. Now on 13.2. Good one to remember before a complete wipe and load.

What is the output of the Terminal command below ?


softwareupdate --list-full-installers


Does Ventura 13.0.1 appear in this list ?


Example below>>


Mac-Mini-M1 ~ % softwareupdate --list-full-installers


Finding available software


Software Update found the following full installers:


* Title: macOS Ventura, Version: 13.0.1, Size: 11866460KiB, Build: 22A400, Deferred: NO


* Title: macOS Ventura, Version: 13.0, Size: 11866804KiB, Build: 22A380, Deferred: NO


If it does appear, in the Terminal command below will pull the Full Version of 13.0.1 and place a new Application in the Applications folder.


It should be about 12.16 GB in size. It will not Auto Launch


softwareupdate --fetch-full-installer --full-installer-version 13.0.1

update from 13.0.1 to 13.1, I've this issue


i've a Mac mini Intel I7 2018. No issue from 13.0 to 13.0.1

but impossible to update to 13.1


No issue with my internet. I've updated successfully with my MacBook Pro



With all USB devices disconnected, reset smc, nvram, power off --> still the issue

Power off the Mac. Restart in safe mode. --> succeeded to update to 13.1.


Surely one of the kernel extension causing the issue. I've Bitdefender, parallels desktop, OnyX and Tuxera.

Some more information which maybe someone (Apple support?) might understand and have some clues as to why the update is failing.


Going through the logs I found the following in the MobileSoftwareUpdate.UpdateBrainService section (there is a lot more to the dump but this seems the cause of the failure):


MSU - 1041 (failed to perform limited firmware update)


This error occurs during the update preparation just before it fails.


Any ideas?
