macOS Big Sur Installation Failed: 'An Error Occurred While Installing the Selected Updates'

[djrm]

Resolved apparently

why isn't there a just link to download the .dmg installer? this stupid upgrade now button is a joke 😂

 

[satsi]

New error message:
The update was not found
The requested version of macOS is not available.
Once more getting also the warning that "Updates for this Mac are managed externally"
I returned this to Factory Presets before but it seems like it didn't work.

macOS update status now shows as resolved but I'm still having same issue:

Apple - Support - System Status

Status for all planned and unplanned events for Apple Services.

www.apple.com

I wonder if my partial download is corrupted. Anyone know where the partial download is cached?

I don't think that's the issue.

I've been trying to update my iMac all evening. Like everyone else, the download started and I was able to download several GB before getting the error. Then it started happening as soon as I hit the Update button.

Like you, I thought that maybe the partial download was somehow preventing it from retrying successfully once the status went green. So I tried to update my MacBook - which had never previously tried to download it. And that fails too - straight away with the same error.

Not as bad as the MacRumors review video showing off the magnetic card holder and he showed off all his card number information.

Oh, yeah. I remember that one.🤦‍♂️

Hi all, we can install Xcode 12.2 instead.

I saw that, but I can confirm that I'm still having issues.

I’m not going near this today. No way.

You don't have to "go near it".

Seems a lot more systems that we all use are being affected whether or not we tried to download the Big Surprise.

 

[vaugha]

still getting the error message. It's not fixed.

 

[BigMcGuire]

Where are the partial downloads stored? I'm definitely seeing lost space on my Mac hard drive from this. Anyway to clear?

 

[Bandaman]

still getting the error message. It's not fixed.

Post a screenshot so we can see what's going on.

 

[bevo]

Didn't resolve anything in New Zealand?

You know those were all fake cards for the review. They all said Fantom on them

The apple support system status says the Installation Failed problem is fixed...it is not. I am still getting the error message.

Same here

 

[patimages]

Out of curiosity, some members mentioned that the issue what due to an issue with Akamai : how did they figure this out ? Can't find this in my logs.

 

[Pizzakoerier]

Nope, still fails instantly (in Belgium) when I hit the update button.

Not good, Apple. Not good.

 

[MacDevMike]

Again wondering if someone knows where the installer is stored...I can't find it. It used to be in Applications, but its not there and I can't find it in Alfred searching "macOS Big Sur" or any other installer name for that matter

Edit out your serial number, dude.

I never understood the concern about sharing a serial number? Can‘t imagine you could do a lot with it other than check the spec and AppleCare status?

 

[fallingrock0]

Yeah, same here. I had already downloaded 12.8gb before it failed the first time.

This is definitely not fixed. Someone's gonna get fired at Apple today...

Yea, a serial number isn't the same as your phone number, SSN, Credit Card number.

 

[Bandaman]

It's downloading on my iMac now, but not my MacBook Pro. I'll just use the installer from the iMac when it's done.

Edit: I lied, it failed again at 2 GB.

Didn't resolve anything in New Zealand?
