Update to Sonoma 14.5 fails

I’m trying to update my 2020 Intel Macbook Pro to Sonoma 14.5. The update downloads but the installation fails at the next step (preparing the update) every time. Following suggestions I’ve found online I’ve tried a different internet connection, tried booting into safe mode, tried installing via a new user. Anyone else having this issue?


I usually wait at least a few days before I do these updates. I’d give it a couple of days and try again.

No issues here but I’m on apple silicon. May be worth downloading the full installer from the App Store and try installing that.

Update: my wife’s MacBook Air 2020 Intel updated just fine as did my Mac Mini 2023 M2 Pro. As suggested I’ll try again in a few days and then go for the full reinstall if an update fails.
