Additional Notes
  • Updates might not show up in Settings as soon as it releases if you have Rosetta 2 installed. This is due to Apple not releasing Rosetta at the same time as macOS Tahoe Betas. Please wait up to an hour before you will be able to update.
  • If you are encountering a memory management issue (eg. a Memory Leak), please provide what app/process it is coming from (Using Activity Monitor) and what you were doing in that app.
  • macOS 26 Tahoe will be installed via a Delta Update in System Settings. Please be aware about this, as the update won’t install with an installer.

beta 4 is working with nordvpn (after not working in beta 3); good to see this fixed promptly (am guessing others with adblockers & other vpns should be ok).....

if you're on .3, you have nothing to lose by going to .4, either way. (fwiw, 1blocker worked on .3, and still works...)

I'm on beta 2 and did not install beta 3 due to Adguard problems, so I'm trying to figure out if I can safely update to beta 4 or not
