Apple today provided the third beta of an upcoming macOS Tahoe 26.3 update to developers for testing purposes, with the update coming a little over a week after the launch of the second beta.

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, and no new features were found in the first two betas.

We'll likely see Apple release macOS Tahoe 26.3 at the end of January given past launch timelines.

Updated and just had four mdworker_shared crashes in first 15 minutes. Not a confidence builder! And FaceTime again does NOT see webcams in dual 27" ATD.
 
Its safe to move to this from Sequoia?
No. Liquid Ass is garbage, will be garbage, will never not be garbage. I've only run Tahoe Liquid Ass garbage in a UTM VM and in this UTM VM Liquid Ass garbage locks up easily just by running Maps and Weather. I'm skipping all v26 garbage on all devices and have slight hope 27 will be better than garbage but not a lot of hope. It inspires no confidence that everyone more senior than Anal Dye approved and presumably thought this garbage is ok for their hundreds of millions of customers. Well Timmy C doesn't use Macs, his CEO desk only needs an iPad, but even on iPad Liquid Ass is garbage although not as much garbage as Liquid Ass is on the Mac where it attains its maximum garbage-osity. We'll see, now that Ternus is the new software design overseer and on the way to the CEO chair, maybe better decisions will be made tbd.

I agree 1000%. They went WAY off the rails with Tahoe. Never should have happened. We would have been happy with sequoia forever. I will find a way to never update to this rat's nest of an OS. Did we learn nothing from Windows VISTA???

I'm not a power user. Just someone who uses my Mac minis a LOT. And this is the type of feedback that always has me waiting for a LONG time before updating my OS. I'm currently on Sequoia and I will wait as long as it takes. For reference, my Mac mini history...

2007 - Finally had too many HD issues, retired Dec. 2025.
2012 - Still going but showing its age. Some websites won't work.
2020 - I'm soaking in it. :D

So as you can see, I don't update hardware unless there's a real need. Which brings up a very interesting question...Is it worth getting a new Mac mini knowing it will be shipped with Tahoe? Are we at the point now that people are going to wait to update not because of hardware but because of the OS?

Good question. I am pretty sure you meant Tahoe. I would LOVE to purchase new with Sequoia :)

I'm hopeful a post-Tahoe macOS will have its UI de-******tified. Used to be we had some smart dev who could figure out a hack to fix UI issues that Apple broke.

Someone please smack Tim upside the head with all Inside Macintosh volumes...

NO! Don't do it. I tried Tahoe for almost 4 months. All the way to 26.2 and reverted back to Sequoia few weeks back. Took me whole weekend to go back on my M4 MacBook Pro. I have almost 4TB of data on the SSD harddrive so the full new backup and copying back from backup was about 17 hours each time. It was a pain and cost me so much lost time.

Tahoe looks and behaves really bad. I don't understand how someone on this very forum praises the look. Sorry folks if I don't care about looks as much as I care about functionality, speed, precision, stability and focusing on my content. Tahoe's design elements are constantly screaming at you - look at me! It's distracting. Or, you cannot find them when you need them fast because they are "melting" into your content due to Liquid Glass.

And the insanely rounded corners everywhere that cut off valuable space AND content!!! For example I use my desktop to store pictures and video files for my immediate projects for easy drag and drop. The extra rounded corners on the desktop icons now cut off so much content that you can't see what the icons represent. You have to adjust the size of the icons to be much bigger. Therefore, taking up more space, so you can't fit as many as needed on the desktop.

I don't understand whose stoooopid idea this was. It must have been someone working on 30" monitors. But if you use 13" Air or 14" Pro with limited screen real estate, the excessive ROUNDNESS of everything doesn't allow for the same fit/look of your files and content like on Sequoia or prior (my very first Mac had Leopard OS on it) so I know what I'm talking about.

The whole system now looks like lego DUPLO for kindergarteners.

I have iPhone 17 Pro and I have iOS 26 on it. It's fairly fine on the iPhone - but I did have to turn on the Tinted version of Liquid Glass to improve readability. However, Tahoe with its new redesign is not fine. I don't even mind the Liquid Glass effects, as we can make it look more Tinted or frosted now, as I mind the redesign of the OS. The new lines everywhere like on the sidebars in every app, bunch of new uneven lines in and around menus, weird padding around sidebars and control elements/buttons, stupidly positioned buttons and menus, stupidly inconsistent shapes of buttons and padding around them. Content moving through/behind menus and buttons and sidebars. It's all more distracting than ever. The macOS is now distracting and wants to be more important than your content! It's getting in the way of your content! Instead of being in the background working for you invisibly and be there when you need it - it screams LOOK AT ME! And at times it hides so well you can't read/see what the buttons are.

And has anyone mentioned the new dumbass position of the control menu in the Music app on the very bottom? I mean what the... Whose idea??? Who approved it??? Who thought this was an improvement??? It can work on an iPhone because your thumb is on the bottom of the screen. But it is truly one big idiotic decision to do it on a desktop.

NOPE!!! I'm skipping 26 altogether and will stay on Sequoia until 27 comes out, and we will see what they come up with there.

You will NOT be missing out on any security as Sequoia will be supported and getting updates for minimum of next 3 years. I hope that by that time, the new design team who took over, after the "firing" of the old design chief Alan Dye, will come up with much needed improvements.

Lastly, we are only 5 months from the new os 27 being shown and announced at the WWDC. I can easily wait to see what's cooking until then.

I work for a large corporation and they are making everyone move to Tahoe by Feb 20.

I guess outside of liquid glass everything is stable enough for a blue-chip tech company to force users to upgrade.
 
We are at 26.3 beta3 now and Apple still could not fix that annoying Dock Folder jump issue (when Dock Magnification is enabled, the Dock Folder abruptly jumps approx. 10-15pixels down as the user moves the cursor after a brief pause). FB20761846, opened in October, 2025.

I feel you, but I imagine they have a way bigger fish to fry right now.

Right. It's a minor thing but I see this bug repeatedly every day (I have Applications pinned to the Dock) and continuously get a reminder about the state of things. Anyway, hopefully we'll get this fixed by the time macOS 27 arrives. :)

What are you talking about. It was not the interface that was the issue with Vista, in fact that is one of its positives.

It was the under the hood performance that was the issue with Vista. On RTM (no service pack), basic file copying was at least twice as slow as XP, file search was slow compared to XP. Then you had most OEMs shipping Vista on underpowered devices for the job to name but a few issues with it. Remember Windows 7 is based on Vista SP2 and by that point hardware had mostly caught up and the issues ironed out.

Windows 7 was the best OS ever :) We learned a lot from VISTA back then. And Apple undoes all the learning with Tahoe. Useless changes that are not meaningful in ANY way do not an OS upgrade make.
