Unable to update to 12.1PB?

Using a MBP M1 Max and have suffered a few glitches with 12.0.1, so wanted to update to 12.1 RC2 PB. I loaded the profile but software update just sits with 'finding update'. Tried various restarts. Tried a search on the forums, but didn't find anything.

I'm a registered dev, so tried the dev profile on the off chance but got the same issue - making me think it's something else. I'd sooner use a PB on a daily driver.

Any ideas? :/

I forgot how to do it exactly. But I remembered that sometimes the seedutil thingy can get bugged out. I think the utility has an argument to reset it or something. Try googling about that utility. It's either seedutil reset or fix .

Thanks for the feedback - good tip! Doing the search on DDG turned up some weird results?! Google was better. :|

Using the tool, it reports that I'm enrolled correctly and I ran the seedutil fix command (no reset in the args), but still no joy. Can I do an in-situ install from a 12.1 restore image, or does it do a compete wipe?

As far as I know. There is an option using ipsw to either flash the firmware without resetting data or the one which factory reset it. I recommend watching Mr. Macintosh's videos on YouTube. They are very helpful and he explains everything usually about using Apple Configurator etc..

I'm still on beta 1 and really wanting to use the RC. But yeh full installers aren't available and I want it to be safe so yeah gonna wait for public release I guess. I heard it's gonna come out next week

I've already got the 12.1 restore image, but not familiar with Configurator on the Mac side - only iOS. I'll take a look at the video or maybe I'll wait a few days. Thanks for your help!

Okay, cool that I waited - but it still won't see the update. What now?
 
Yup, that's right. I knew there was a problem there...

Edit: I've tried booting in safe mode several times - It seems blind to any update. The OS is only a month old - fresh install with the machine. :|

That's weird. It's like the software update profile got broken or something. Does enrolling to a beta and then back to stable works?
 
I’ve tried every profile state and trick I could find. Nothing. Then I unenrolled it and downloaded the final 1.2 installer. I’m going to nuke it from orbit - It’s the only way to be sure!

Edit: I say that - The installer appears to have hung at 52 mins. I’m going to wait a bit and see if it carries on.

Hung on which part? Like installing from opening the .app?
 
Hung after triggering the install OS to disk part - where it copies files.

I did some looking in Activity Monitor and found a possible culprit - apple.com.softwareupdatebrain which was using 99% cpu. I killed the process and the 12.1 update appeared immediately in software update. :eek:

However, the download in software update seems to have paused - I’m giving it a few minutes. I’m on a 600Mb connection. If this doesn’t work, I’m either gonna do a last backup and full wipe/restore or contact Apple Support.

This OS has been terrible - I’ve never had troubles like this before…

If things still not working. I recommend trying to install it using the bootable full installer instead. Usually that works better

When making the bootable installer using the createinstallmedia . Don't forget to use the download-assets argument too. By the description it should download many of the needed things and save it so you can install it more quickly later

I haven't done a boot drive for about 5 years - How long does it take? It's been at least an hour...
 
Edit for clarity: The make USB installer part - currently copying to disk? Terminal says:

Copying to disk: 0%...

Oh is the USB slow? It's fast on mine since i have a small external SSD to have my bootable installer in case

I've just realised I'm using an old USB 2.0 thumb drive. ?‍♂️ Will see what I have...

Edit: Got another drive - I've increased the write speed by a factor of 30x. What an idiot.
Edit2: And it's complete...
