What does the pointer look like? Has it been glassed?
No, the edges have been rounded off and both the pointer arrow and the hand (no longer the Mickey Mouse glove) look decidedly off to me. I have my pointer slightly enlarged for better visibility and it just jars for now. As do the window resizing glyphs. Maybe it'll fade with more use as I acclimatise.
That and the missing compact tab view in Safari are my biggest hurdles. But overall I'd say macOS is suffering at the expense of iOS and iPadOS. I'm all for harmonising between systems but all systems need to be considered equally in that case.
[UPDATE] Having installed the public beta as my daily driver and played with it more, the pointer arrow and the window resizing glyphs are starting to feel more 'normal'. The replacement for the Mickey Mouse glove however still feels amateurish and not in keeping. Hell, the old one had the finger more aligned with the pointer direction - this one, not so much!
I really do miss the compact tabs in Safari - for the most part the reload option within the individual tabs themselves. If they added that back in maybe I could just about accommodate, but I would rather like to see the whole compact tabs environment restored as was. There's no need to change for change's sake and it's not like there's consistency with iOS - that has the URL bar at the bottom!
All-in-all both macOS 26 and iOS 26 public beta are pretty stable. I've had one, maybe two, glitches but nothing requiring a reboot.
I would say that currently the 'glassification' of macOS 26 is way more subdued than iOS 26. I run dark mode and Liquid Glass barely shows up. macOS is either way behind the development focus (more than likely given that iOS and iPadOS are the babies and cover more devices) or they've decided to tone it down in macOS which makes a mockery of the whole 'platform consistency' bit and seems more unlikely.
But then macOS still has 'System Settings' vs the others. Be consistent with consistency please!
Hopefully, macOS - now being the runt of the litter - we might see it catch up nearer release time but overall I'm happy with it so far. YMMV.
