So, Apple finally pushed the macOS 26.3 public beta to the wild. Honestly, it feels like we just finished debating whether the initial "Tahoe" release was a "big" enough update, and here we are, already deep into the point-release cycle for 2026. If you’re like me, you’ve probably seen the headlines screaming about "game-changing AI" or "huge design overhauls," but the reality of the macOS 26 public beta is actually a bit more nuanced—and, frankly, a bit more interesting—than the marketing fluff suggests.
Let’s get one thing straight. This isn't just another incremental patch. It's the first time we’re seeing the long-promised Google Gemini integration for Siri actually start to breathe in a public testing environment. Apple confirmed back in early January that they were teaming up with Google to give Siri the "brain transplant" it’s needed for a decade, and that’s the big elephant in the room with this beta.
The Liquid Glass Obsession
Everyone is talking about the "Liquid Glass" design. It’s the primary visual shift in macOS 26, and if you’ve been sticking with the Sequoia-style matte looks, this is going to feel... shiny. Very shiny.
Apple’s design team basically decided that "translucency" wasn't enough. They wanted refraction. Now, when you drag a window over a colorful wallpaper, the sidebar doesn't just get blurry; it bends the light. It's a vibe. Kinda reminds me of the old Aero glass from the Windows Vista days, but, you know, executed with that $3 trillion Apple polish.
The coolest part? Color-coded folders. I know it sounds like such a small, dumb thing. But for anyone managing fifty different project directories, being able to right-click a folder and turn it "Electric Blue" or "Sunset Orange" while slapping an emoji on it is a massive workflow win. It’s one of those "why didn't they do this in 2012?" features.

Why the macOS 26 Public Beta is Different This Year
Typically, by the time we hit the .3 or .4 beta cycle in January, things are just bug fixes. Not this time. Because Apple shifted their numbering schema (jumping to 26 to match the year 2026), the release cadence feels faster.
The big standout in this specific public beta is the Phone App for Mac.
Yes, we’ve had FaceTime and "iPhone Mirroring" before. But this is different. It’s a dedicated Phone app that brings your iPhone’s cellular call logic directly to the desktop.
- Hold Assist: The AI literally waits on hold for you and pings you when a human picks up.
- Call Screening: It works just like the Google Pixel feature—Siri answers, asks what they want, and gives you a live transcript.
- Keypad Access: No more fumbling with your phone to press "1 for English" during a bank call.
It’s about making the Mac feel less like a "computer" and more like a primary communication hub.
Spotlight is Actually Useful Now
Is it just me, or has Spotlight been "just okay" for the last five years? In the macOS 26 public beta, it’s basically been turned into a command line for normal people. They’re calling them "Quick Keys."

Instead of just searching for "Draft email to Sarah," you can actually type it, and Spotlight pops a small compose window right there. No opening Mail. No distractions. You can execute hundreds of these "system actions" like setting reminders, playing specific podcast episodes, or even toggling system settings like Dark Mode directly from the search bar.
The Clipboard History Fact-Check
There was a lot of noise about Spotlight getting a full clipboard history. It’s there, and it’s... fine. It remembers text, links, and images for a few days. The "context awareness" part is the real kicker, though. If you’re working in a Keynote presentation, Spotlight will prioritize surfacing that chart you copied three hours ago rather than the random URL you copied five minutes ago. It's subtle, but it works.
The Siri-Gemini Hybrid Reality
Let’s talk about the Siri update because there’s a lot of misinformation floating around. Some people think Siri is gone and replaced by Gemini. That’s not what’s happening.
Apple is using Gemini to handle the "world knowledge" stuff—questions where Siri used to just give you a list of web results. The on-device Apple Intelligence still handles your personal data, like "When is my flight?" or "Find the photo of my cat in a hat." This macOS 26 public beta is the first time we’re seeing that handoff happen. When you ask a complex question, you’ll see a small "Gemini" logo or a specific animation indicating the external model is being tapped.
It's a weird compromise. It’s fast, but you can definitely tell when the "local" Siri stops and the "cloud" Gemini begins. There’s a split-second lag that wasn't there before.

Should You Actually Install It?
Look, I’m an expert, but I’m also a realist. This is a beta.
While macOS 26.3 is surprisingly stable for a January release, there are still some weird "beta-isms." For instance, the new Liquid Glass effects have a habit of flickering when you wake the Mac from sleep on some M2 MacBook Air models. And if you rely on third-party audio drivers or niche kernel extensions for music production? Stay away. Just don't do it yet.
Device Compatibility Check:
Apple finally started the "retirement clock" for Intel Macs. While Tahoe (macOS 26) still supports the 2019 Mac Pro and the 16-inch Intel MacBook Pro, it’s the end of the road. If you have a 2018 Mac Mini, you’re stuck on Sequoia.
- Supported: iMac (2020+), MacBook Air (2020+), MacBook Pro (2020+), Mac Studio (All), Mac Pro (2019+).
- The "Gold" Standard: To get the most out of the Gemini features, you really want an M4 or M5 chip. The M1 and M2 machines struggle a bit with the real-time Live Translation during calls.
Making the Jump
If you’ve decided to ignore my warning and install it anyway, do it the right way. Don't just hit "Update."
- Time Machine is your god: Backup everything. Seriously.
- Separate Volume: Don't overwrite your main OS. Create a new APFS volume in Disk Utility. It takes five minutes and saves you a week of headaches if the beta bricks your workflow.
- Beta Updates Toggle: You don't need a "Beta Access Utility" anymore. Just go to System Settings > General > Software Update and click the little "i" next to Beta Updates. Select the macOS 26 Public Beta.
Actionable Next Steps
- Check your storage: The Liquid Glass assets and the local LLM models for Apple Intelligence take up a surprising amount of space—expect to lose about 25GB to the system.
- Test the Phone App: If you have an iPhone on the iOS 26 beta, try the "Hold Assist" first. It is the single most satisfying way to deal with customer service.
- Personalize your folders: Spend ten minutes color-coding your desktop. It feels like a new computer without spending $2,000.
The macOS 26 public beta is less about "new toys" and more about Apple finally admitting that the Mac needs to talk to the rest of the world—whether that’s through your iPhone’s phone number or Google’s AI. It’s a transition year, but for once, it’s a transition that actually feels like it’s going somewhere.
