Cant' update to Big Sur - update not found the requested version of macos is not available

I just checked - my 2012 Macbook Air isn't compatible - neither is my 2012 iMac - ****! Time to start thinking about an IT refresh I think.

You could be right but since Apple has provided specific documentation related to MBP 2013 - 14 incase of a failed Big Sur upgrade, it would seem abnormal to "retire the update for 2013 and 2014 MacBook Pro " at this time.

Best of luck

I also have this problem. I run a MacBook Pro (Retina, 13-inch, Late 2013) which should be supported to install Big Sur. But I get the same message...I remember when BigSur was published I saw the update in the Softwareupdate part. But now not anymore.

Official, no. I found this article…

Same for me. I have a late 2013 MBP and I am getting the same error. I have Big Sur on a USB stick and attempted to run the install with the same error. App store says my device is up to date and if I try to download Big Sur from App Store I get a message that it is not available...

If as people stating the fix is to replace the i/o board, it costs $25 and here is how to do it in order to unbrick your macbook pro

and here is where to purchase it

Again, this is the case if the i/o board unbricks the laptops. As I read, this is what Apple is doing and charging between $150 - $500.

Hey, don't jump on me. I might be wrong. I only read about it on the net and didn't try it myself.

Same here (just to keep the thread alive): MacBook Pro 13" Retina Late 2013.

I tried some of the described tricks here, but none of them worked.

The App Store lists Big Sur, I can click "Download", but then it reports that it cannot find the update.

I am facing same problem while updating the Big Sur, before I couldn't downloaded it now I am able. to download but unable to install it it shows "installation error occurred" anyone with this problem and got solution let me know

I'm also having this problem, has there been any more information about this? I have a 2017 Macbook air, my wife has a 2019 macbook air and is also having the issue. It's as if it doesn't exist here. We're in Canada.

I just tried this morning - 4th February, 2021 - for my 2012 Macbook Air 11" and have the same problem. The app store claims that the Big Sur update cannot be found, even though I'm clicking 'get' on the Big Sur page. This is stupid. Apple need to fix this.

I also tried going to the Apple website for Big Sur and clicking 'get' and it takes me straight back to the app store - same problem. So even though my Macbook Air is compatible according to the Big Sur specifications, I can't update it to Big Sur.

So is Big Sur still in the Beta phase? I Updated Catalina to 10.15.7,

and it's working fine. Silly question when is 11.1 no longer Beta? When

it's 11.2 or when Apple says it is no longer Beta? I have a maxed out

2019 16" MBP.

What method did your friend use to UpGrade to Big Sur that is different from your method? Have you opened the Apple Apps Store and attempted to download Big Sur via that method?

was this solved??

same problem here
