When I try to update my MacBook Air from 14.6.1 to 14.7 or to Sequoia it doesn't allow me to update and gets an error message as " Failed to personalise the software update". Does anyone has the same issue with updating your MacBook?
MacBook Air 13″, macOS 14.6
I haven't seen this error personally, but I have seen other threads reporting the same strange error dialog.
See: Error "Failed to personalize the software… - Apple Community
You might need to "revive" or "restore" your Mac's firmware with the aid of another Mac (and possibly of an Apple Store). See the TidBITS and Apple Support articles to which I linked in that thread.
Try and boot your mac in the safe mode to see if you can update via the safe mode
Start up your Mac with Apple silicon in safe mode
> Shut Down.this is what I did to resolve because I had a folder Rosetta sitting in my /Library/Updates folder which seemed to be hindering things, I also couldn't remove SIP to remove the folder and after looking a several different solutions came up with these steps to resolve:
1) removed appleID from the system , system settings/select ID, remove account
2) booted into safe mode, opened terminal and disabled SIP using: csrutil disable
3) rebooted into safe mode and cleared the folders (in my case Rosetta) from 'VloumeName/Library/Updates' leaving just the plist files in there in my case command was sudo rm -R '/Volumes/Macintosh HD/Library/Updates/Rosetta'
4) rebooted again into safe mode and requested update via terminal sudo softwareupdate -i -a -R
5) system rebooted a couple of times
6) logged into new 15.1 beta 4 (this will vary depending on your upgrade track)
7) rebooted again into safe mode, then turned SIP back on using csrutil enable in terminal
8) rebooted normally and added my iCloud/appleID back to system
hope this helps you or someone else
cheers
Thanks for the suggestion but i have tried it via safe mode as well and its of no use. I have also tried to install the update from the app store but results the same.
