So, Apple just dropped the latest macOS Tahoe public beta, specifically version 26.3, and honestly? It’s a lot. If you’ve been scrolling through social media, you’ve probably seen the "Liquid Glass" redesign. It looks like someone took the old macOS interface and dipped it in a bucket of high-end translucency. It's pretty. It’s also kinda polarizing.
Some people love the way the windows now refract the colors of your wallpaper. Others? Well, let’s just say there’s a very loud corner of Reddit currently complaining about "exaggerated curves" and "wasted screen real estate."
What’s Actually New in macOS Tahoe?
Forget the marketing fluff for a second. The biggest shift in the macOS Tahoe public beta isn't just the aesthetics; it's the "Phone" app. No, not just FaceTime. We’re talking about a dedicated app that relays cellular calls from your iPhone using Continuity. You can screen calls, use "Hold Assist" to let the Mac wait for a human to pick up, and even get live transcriptions. It’s the kind of feature that makes you wonder why we didn't have it in 2018.
Then there's the Spotlight upgrade. It’s basically a command line for people who hate the Terminal. You can now execute hundreds of "system actions"—like sending a message or toggling a specific setting—without ever touching your mouse. They even sneaked in a clipboard history manager. Finally.
The Apple Intelligence Factor
The "Tahoe" name (internally known as macOS 26) is heavily tied to Apple Intelligence. If you’re running an M-series Mac (M1 through the brand-new M4), you get the good stuff:

If you’re still on an Intel Mac, I have some bad news. While you can install Tahoe on a 2019 MacBook Pro or a 2020 iMac, you’re basically getting a "Lite" version. No Apple Intelligence. No fancy AI-driven "Edge Light" for video calls. Apple has pretty much signaled that this is the end of the road for Intel support.
Is the macOS Tahoe Public Beta Stable?
It depends on who you ask.
I’ve seen reports from developers like "Sackadelic" on MacRumors saying the 26.2 release was stable, but the early 26.3 seeds have been hit-or-miss. Some users are seeing a 20% hit to battery life on MacBook Airs. Others are dealing with "ghosting" on the mouse pointer where the cursor just vanishes for a few seconds.
The Liquid Glass UI is also a resource hog. If you’re on a base M1 MacBook Air with 8GB of RAM, you might find the animations a bit... crunchy. The transparency effects look great on an M4 Pro, but on older hardware, they can cause the window server to spike.

Real Talk: Don't Put This on Your Main Mac
Seriously. Unless you’re a developer or you have a secondary "mess around" Mac, stay away from the macOS Tahoe public beta for a few more weeks. Version 26.3 is expected to hit the general public in late January 2026, and by then, the most egregious bugs—like the one where the "Creator Studio" apps crash on launch—should be squashed.
Actionable Steps for the Brave
If you absolutely must try it, don't be reckless.

- Time Machine is your god. Back up every single byte before you even think about clicking "Update."
- Check App Compatibility. If you rely on specialized tools like Final Cut Pro or Logic Pro, check the forums. Many third-party plugins are currently breaking under Tahoe’s new security layers.
- Partition your drive. Instead of overwriting Sequoia, install the Tahoe beta on a separate volume. It takes 20 minutes to set up and saves you a week of headaches if things go south.
- Report the bugs. Use the Feedback Assistant. Apple actually listens to beta testers during this phase, especially regarding UI quirks like the "oversized" window corners.
The macOS Tahoe public beta is a glimpse into a future where the Mac and iPhone are basically the same device. It’s beautiful, it’s buggy, and it’s very, very translucent. Just make sure your backup is ready before you dive in.
