Apple today provided developers with the ninth beta of macOS Tahoe 26 for testing purposes, with the update coming a week after the eighth beta.

Registered developers can download the new beta software through the System Settings app.

macOS Tahoe features Apple's Liquid Glass redesign, which extends across all of the new updates this year. Apple also brought the Phone and Journal apps to the Mac for the first time, and introduced a new cross-platform Games app.

With the update, Apple overhauled how Spotlight works, enabling new functionality that allows it to be used to complete all kinds of actions like sending emails without having to open up an app. There are also changes to a number of apps, including Messages, Safari, and Notes.

All of the new features that are included in macOS Tahoe are outlined in our dedicated roundup. macOS Tahoe is set to launch this fall.

Just now installing
macOS 26 PB 5 (25A5349a)(16.83 GB) going from macOS 25.7 PB ? (24G217).
on my
MacBook 22 Air.

I imagine we will see macOS 26 PB 6 (and the xOS 26 PB's) around 1600 EST today, latest 1300 EST tomorrow.
((and it came! macOS 26 PB 6 (tbd)(9.46 GB). Installing now!))

Now running
iOS 26 PB (23A5330a)
on my
iPhone 25e
been running the PB's for a few weeks now, and have had few problems (although I am not keen about all the rounded boxes, and stuff hidden down into menus so search boxes can be so prominent).

Interesting enough, all my other Apple devices got their beta updates, but for some reason my M4 MAX hasn't. Guess patience is the name of the game.

Nothing has changed!!! Safari, as i write this on my ipad, is asking to fill in my password for this site in this textbox! Been like that for 5 betas. I guess it’s an ok bug to carry thru. Totally not a security issue. WTF!

macOS is the same. Not a single bug fixed. Music still opens in a tiny window, resizing often causes it to panic and compute like a slug. Not a damn thing has changed since B3.

Am I taking crazy pills? What is Apple even doing with their software???

How come this new macOS Build number ends with "b" if the previous ended with "a" does this mean we are farther than before of what they considered finished release? I dont see many bugs on macOS like I still see on iOS 26
 
Can anyone explain why the macOS betas are SO DAMN SLOW downloading? I can download a 12 GB file in a relatively short amount of time, but these betas say they will take 2 DAYS to finish. Meanwhile, the iOS and tvOS betas download in what feels like perfectly normal amounts of time.
 
since 3 release's ago, i used to get stuck on a blank page when loading tabs or switching tabs in safari. Particularly heavy pages like proxmox or unifi , seems to be fixed, nice and snappy...
 
i just noticed that my carefully curated folders of apps have been replaced by all my apps in a jumble under some generic group names. wtaf, is everybody at apple UI Dept taking leave of their senses?
