> For context, there have been issues with MacOS 26 which have led many people to defer upgrading
For me the issue is liquid glass. Which I doubt is getting fixed any time soon
I found if you turn off transparency effects and turn on high contrast in the accessibility settings, it's actually a pretty nice looking UI. Still has some dumb quirks like inconsistent corner radiuses and text appearing under UI elements (because they're assumed to be transparent, but aren't). But all software is trash in 2026 so be thankful it isn't even worse, I guess.
27 is a lot better. You can make the UI opaque again (they provide a transparency slider)
I bought a MBP mainly for the hardware, otherwise I'd have stuck with Linux. OS-wise, the jump from Monterey (which I'd last used) to Sequoia was smooth and still feels that way. I prefer not to notice the OS at all, something that I feel would be hard to do on Tahoe due to all that liquid glass and dumb transparency and animations.
Seriously, who the heck even asked for those?
macOS 27 does polish Liquid Glass and makes it look passable on macOS IMHO. It was very bad on 26. Comically bad.
I hate the round corners. It's already too much on 15, but way worse on 26. It looks like "Baby's first OS", designed by Fisher-Price.
Same. It's not the worst thing in the world, at least with Reduce Transparency enabled in the Accessibility settings, but I still don't feel any inclination to upgrade. My personal Mac Studio is macOS 15 and my work MacBook is on macOS 26, and I don't think there's a single thing that I find to be better on the work laptop than on my personal machine.
I might update to macOS 26 in September to be ready to update to macOS 27. Being two versions behind doesn't seem reasonable and I'd rather be on the "Tahoe but less shitty" version than Tahoe itself.
You can disable it in the accessibility preferences.
Also a liquid glass hater, but for what it's worth, 27 is supposed to make it a little bit better. I would prefer to go back to what I had before I had to upgrade into this horrible UI, but this is better than nothing.
