Developers can download the ‌macOS Tahoe‌ 26.3 update by opening up the System Settings app, selecting the General category, and then choosing Software Update. Beta Updates will need to be enabled, and a free developer account is required.

There's no word yet on what's included in ‌macOS Tahoe‌ 26.3, but we'll update this article if new Mac features are found.

The beta is available to developers right now, but a public beta is expected later this week. We'll likely see Apple release ‌macOS Tahoe‌ 26.3 at the end of January given past launch timelines.

We don't need more "features". Fix the current bugs. Finder is a mess for example.

I just upgraded to macOS 26 and I swear it's messing with my eyeballs. Am I crazy or do the buttons on toolbars have these subtle blurred drop shadows. I catch the effect while scanning across the displays and it is making my eyes do a double take. It's very annoying.

Is there any way to just get a crisp, clean, grayscale interface like the old NeXT machines.

Also, the corners should be 90° to better fit the 90° corners on my monitors. I got the little curly triangles all over the place.

And...well let's just leave it there.
