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 update 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; fortunately for me I made the cutoff being 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 your MacBook’s compatibility, I recommend that you take a look at this link to learn more.

If re-enrolling didn’t work for you, than this should work for you:

Open terminal command + shift + T and run:

sudo -i

Copy

Enter root password:

/System/Library/PrivateFrameworks/Seeding.framework/Versions/A/Resources/seedutil

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.
