I don't know if it has been mentioned here or elsewhere in the forums, but the latest version of the free TinkerTool app effectively allows you to turn off Tahoe's Liquid Glass interface and returns you to the Sequoia interface in apps that use it – including Music, Mail, Safari, Calendar, Notes, Reminders, and of course the Finder.

The Terminal commands are discussed in the thread to explain what the app does when you click the buttons.

When you mention TinkerTool, or any other such app, include a link to the official website so that people don’t end up installing malware. https://forums.macrumors.com/threads/tinker-tool-malware-problem.2463235/
Yes, I understand what it was doing, and for many people knowing the individual terminal commands for individual apps is both educational and handy. But like most people, I prefer a one-click solution that turns Glass off completely from the entire system (as much as can be done, anyway) all at once, with one single checkbox.

I tried it out and changing it to Sequoia appearance did nothing. I even rebooted. I ran

Code:
defaults read -g com.apple.SwiftUI.DisableSolarium

and verified that it had set that to 1.

I just updated to 26.1 beta 2. So I think maybe Apple already "fixed" it.
 
I ended up turning LG back on anyway. The glitches that appeared when turning it off started adding up and were more annoying than LG itself.

This tweak has been removed by Apple already.

They're going to shove liquid glass shards down everyone's throat, like it or not.

How did they remove the tweak w/o pushing down a new OS version? Was this some silent update pushed thru the security update or XProtect channel? If so, that's concerning from a trust and resiliency perspective ...

26.1 (still in beta) removed the ability to disable Liquid Glass. 26.0.1 (the current release) still ships with the ability to disable it, which reinforces my impression that the current "stable" release of Tahoe is really a "beta" build...

The only time an OS is stable is by the time of the next WWDC, for iOS 26 and macOS 26, they will be stable by WWDC 2026
 
Apple truly sucks now. I'm afraid they are bent on making people want to migrate to Linux. After 25 years with Apple, I'm having incredible doubts about how they can pull out of this nose dive.

Same.
I'm basically expecting to get pushed off the Mac (and thus out of Apple totally at that point) from them getting over zealous with the lock down at some point.

I don't see it nowhere near that bad. It works great for me and the Liquid Glass is just not that much of a problem. Certainly not to a point where I might use a different operating system.

I expect that liquid glass will become a standard both for LINUX and MICROSOFT.
At that time APPLE might turn in another, unwanted, direction.
And all the time we simply continue using computers ...
;JOOP!
 
Why did people think this is gonna last? The same happened with Big Sur. You could revert to Catalina UI, but it didn’t last long
And another thing to keep in mind: yesterday made ridiculous, today criticised, tomorrow accepted, and don't say never.
Example: 1960 Engelbart invents Windows, 1968 made a fool: "This is for idiots", 2015 everybody uses it, even us.
;JOOP!

Do you mean the Reduce Transparency options that folks have been using? Whatever the reason/method, this is very disturbing and arrogant of Apple to presume to tell us how our UI *must* look even inside its historical walled-garden.

No. This thread is about a hack that disables Liquid Glass using terminal commands or through the TinkerTool app. That hack no longer works. Apple is not going to mess with Reduce Transparency. That will still work the same as before.

FYI, in 26.1 beta, when I turn on reduce transparency the dock becomes near black (I use dark mode). It's kind of ugly.

It's like passive aggressive design. Oh you don't like our beautiful liquid glass? There! Happy?
 
After a month of Tahoe's seemingly controversial visuals, Bob Pony is apparently among the first to discover and reveal a hidden key that largely, actually, tells the system to continue using Sequoia-style visuals for all kinds of things: windows, sidebars, toolbars, widgets, and more. Even the Music app is reverted!


Adam Engst also explains how to enable this using a Terminal command.

(Please use caution and ask yourself whether you're comfortable before tinkering with "plists" or Terminal commands.)

As Bob points out, it's not perfect. App icons in the Dock still bear the specular highlights, Control Center becomes fully transparent, photos in the Photos app hide behind the sidebar. The Contacts app, while thankfully largely reverted, isn't quite right.

But for me, who, after a month, has never suppressed my internal questioning about whether the zealousness of the "new design" and Liquid Glass are appropriate for the Mac – a true first for this longtime Mac user – it still provides more relief than Tahoe provides delight. I'll be expressing this to Apple's feedback form in my next (of many) chapters of correspondence with it, and I urge the like-minded to do the same.

I've really valued reading the range of opinions and feelings of the community during this dramatic update. When something you deeply care about seems to have gone more than slightly wrong, those who empathize are the next best source of what lacks.

What do you think about this discovery, and about Tahoe after a month?
 
I am sticking to macOS Sequoia until Apple has tamed the UI - and obviously it will take more than 1 revision/year to fix this change. Maybe I will upgrade to macOS 28, let's see. macOS 26 isn't the optimized OS that it should've been, as many have pointed out here on this thread.

Unless you need the features of macOS Tahoe, stick to macOS Sequoia if you can.
