If you’re reading this post I presume you have the same interest in trying Apple’s new operating system which is the successor to OSX. This one is called Big Sur or OS 11.

I’ve been a beta tester with Apple for years, which I typically only use with my personal mac, as I need the stability with my daily coding Macbook Pro.

Anyway, I was having trouble locating the upddate and after a few different options I found only for Catalina beta, I thought I’d write this post to help others.

I should also note that not every Mac is going to be compatible with Big Sur, which is originally what I thought may have been the issue. But fortunately for me I made the cutoff bing a late 2013 Macbook Pro (last model that is officially supported).

List of compatible MACs’:

  • 2015 and later MacBook
  • 2013 and later MacBook Air
  • 2013 and later MacBook Pro
  • 2014 and later Mac mini
  • 2014 and later iMac
  • 2017 and later iMac Pro
  • 2013 and later Mac Pro

If you have any questions regarding that, I urge you to take a look at this link to find out.

If you have tried unenrolling and re-enrolling and that didnt’ work, then this will most likely work for you:

Open terminal command + shift + T and run:

sudo -i

Enter root password:
Unenroll from the Beta Program:
/System/Library/PrivateFrameworks/Seeding.framework/Versions/A/Resources/seedutil unenroll
Enroll in the DeveloperSeed Beta:
/System/Library/PrivateFrameworks/Seeding.framework/Versions/A/Resources/seedutil enroll DeveloperSeed

Close and re-open System Preferences > Software Update

The new Beta should now show up

Let me know if you run into any issues.
