Apple Releases Revised Version of macOS 11.0.1 Big Sur

[Rosen]

This maybe, beware, its a 12.18 GB download.

Did download and tried it: "Cannot continue, the installation needs to get important files that are not available at the moment, try again later".

You’re upgrading wrong.

Hopefully it’ll fix the restoring firmware using DFU mode on M1 macs, and being able to reinstall macOS without needed it a second Mac wired up to run the restore of the OS.

Except for the article says it’s not for the M1 Macs.

I’m probably very late to ask for clarification on this question but: wasn’t El Capitan the “11.0” version of OS X / macOS? So Big Sur should be 16.0? What happened to the old numbering system?!

It was 10.11. Now it’s 11.

how can we get it if we already have Big Sur

Did you read the article?

 

[az431]

Why isn't this just released as 11.0.2?

Again, did you read the article? This is a revised release for people who don't already have Big Sur installed. It is not a new release.

Hopefully it’ll fix the restoring firmware using DFU mode on M1 macs, and being able to reinstall macOS without needed it a second Mac wired up to run the restore of the OS.

As it clearly states in the article it is neither for M1 Macs nor for people who already have Big Sur installed.

Aside from that, it should resolve all your issues.

Call apple to find out if this is for you. And if so, they can direct you where to download it away from normal channels.

 

[az431]

Unfortunately, no way to get it if already on Big Sur. Could try downloading from App Store, but that version says it's a week old in version history.

Why is it unfortunate? Are you just looking to practice installing MacOS? There are no changes.

The new build might be to reject updates on MacBook Pro Retina Late 2013(?)

A few hours ago I deleted the Big Sur install-file that was downloaded, and redownloaded it once again. Just 15 mins ago I did check the build version in terminal, and it was Big Sur build 20B29. Then saw this post about 20B50 – and had to make a post about it.
After checking the build, I erased that Big Sur installer build 20B29-file. Just now, I can confirm my MacBook Pro Retina Late 2013 cannot find any available updates when looking for it – just the way I did a few hours ago when it did find it again.

My thinking is that they have excluded my model from updating to Bog Sur, at least temporary – and perhaps due to the bricking problem until solved.

The app store has last week's version.

The initial Big Sur release couldn’t install on. Fusion Drive Macs and would break Fusion Drive in two parts. I wonder if the second try fixed the problem.

I called Apple Support yesterday and they told me there were numerous reports of the Big Sur upgrade failing on Fusion Drive Macs. Users had to re-create Fusion Drive AMD install Big Sur from scratch. This, of course, lead to the complete loss of data.

I downloaded MacOS from Mac AppStore and now I have the newest build version - MacBook Air M1

Wow, that's something to hear. And use your backups to restore your files.

I think it was last week's version!!

There are two versions - newest with description and older without

 

[jonnysods]

This is why I wait 1-2 weeks until after launch to upgrade. I’m so tempted to update now!

Unfortunately I don't see it. Just last weeks version.

No, the App Store downloads the new version. This exists at least in part to prevent installation on the late 2013 and 2014 MBPs that were not booting after installation.

Check your software update pane, see if its there. Assuming you don't have Big Sur.

OK, go ahead and install it, Good luck!! I was looking at the version history. No need to install it for me.

I did, it installed build 20B50. No issues.

Glad it worked out for you.

 

[halofan56]

Good find. That must be it. They’re doing some additional checks during the install process to avoid older MacBooks getting bricked by stopping the installer. Mystery solved!

This caught my eye from the article......It's not clear why Apple has released a new version of macOS Big Sur 11.0.1, but 11.0.1 is the launch version of Big Sur on all Macs except for M1 Macs. This can be confusing for some people,

 

[halofan56]

Perhaps this is a fix for the installer/upgrade process, hence why its not needed for those already on Big Sur.

The only way to know is a response from some users with this issue on the bricking.

 

[sirozha]

I’m surprised I haven’t read a single report from an owner of a Fusion Drive Mac about how their upgrade went.
