This week was WWDC 25, the annual Apple developer conference were Apple announce’s their next software. This year, one of the many announcements was a UI redesign which they called ‘Liquid Glass’. It will provide a common ‘look and feel’ across their hardware including the Mac. It looks a little different to recent versions of macOS such as Sonoma and Sequoia with visual effects to provide improved separation between UI controls and content.

The good news is that Apps built for earlier macOS versions will continue look just the same on Tahoe. However, that backwards support will be dropped from whatever follows Tahoe. But that’s not something to worry about for a while.

The other thing to note is that Tahoe will be the last version of macOS that will support Intel processors. So, if you are using an Intel Mac and wish to use whatever macOS follows Tahoe then you are going to need new hardware.

Out of curiosity to take an early peek I downloaded the first developer beta and installed SPE Expert Controller v1.2.0. Sure enough, just as Apple said, it looks and works just the same as it does on Sequoia. That’s pretty reassuring and is an early indication that it should work just fine even if it were not updated.

However, my thinking is that I’ll rebuild SPE Expert Controller for Tahoe later this summer so that a Liquid Glass version is available for the public release of Tahoe, presumably around September / October 2025.
