Why? What happened to the magic bar? There are many things Apple changed their minds on.

I won’t be surprised if there is a rollback in 27 (i’m hoping there will be - else going to buy a retro mac with a magic bar upon no tahoe runs).

No need for a retro Mac. macOS Sequoia runs great on all but the very newest Macs, and is still getting maintenance updates. And unlike with iPhones, it's perfectly possible to downgrade Macs back to older macOS versions if you want.

They can't frame it as a rollback at least. Have to sync it up with a new OS release or something as the "new" best thing

They'll just come up with round displays. Like on PDP-1.

finally, we can run SPACEWAR on macOS as it was always intended to be run.
