have found solution

So I ran sudo as root via terminal and typed the commands there:

open terminal
sudo -i
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
