Just like last time, in order to see the update on devices with Apple Silicon processors, delete these two folders. It didn’t work until I did that again.

/Library/Apple/usr/share/rosetta
/Library/Apple/usr/libexec

Does anyone know if the bug in the "launchpad" has been fixed? Or is it just me, that I have problems with it. Even in spotlight when I type the app that I want to quickly launch, there is NO RESULT at all. Not in spotlight, nor in the new Apps thingy... I even tried to rebuild the index but didn't help.

Works for me running Beta 4 under Parallels. Typed in Safari and showed up.

Did anyone get a "Keep all your files in iCloud" message when upgrading? Underneath it had <<DNP>> or something like that. with a checkbox. I checked it and clicked continue and it asked me to upgrade my iCloud storage. I tried and then it disappeared. Is apple testing something like iCloud backup for Mac?

That screenshot with the Finder windows looks awful. Those tab bars… all the rounding… and the distinction between active/inactive is low contrast. They’ve taken something that had consistency and decent aesthetics and turned it into something has no virtually no harmony between all the elements. It’s more distracting, not less, as per their marketing.
 
Apple News app just disappeared. I checked iCloud settings too, just poof, gone. Anyone else? Checked 2 machines on beta 4.

EDIT: Weird, they had it hidden. command-shift "." revealed it:

For the person who always asks in here if the compact view for tabs is back in Safari I am here to inform you once again that it is not.

yeah Safari is still terrible, they still haven't fixed any of the annoyances like not being able to tell which tab is selected. Apple hired the amateur team to work on Tahoe it seems.
 
I'm still not seeing the update and rosetta isn't installed. I also tried installing it through the full installer but after some time, it gives me an error message that a working internet connection is required (it is working, trust me!)...
