macOS Tahoe: Developer Beta 3

Tue, 22 Jul 2025 06:00:00 +0000

A few days ago, right on schedule, Apple released to developers the third update of the macOS 26 Developer Beta, better known as Tahoe.

Once the update is complete, it doesn’t take long to realize that Apple is (slowly) modifying something in the Liquid Glass graphical interface of the latest version of its operating system.¹

Perhaps this is also to address the many criticisms it has received over the last month from big names like Riccardo Mori – whatever you think, his first article on MacOS Tahoe and Liquid Glass is a must-read (but his first and second follow-ups are also worth reading) – as well as from John Gruber, Craig Hockenberry, Francisco Tolmasky, Louie Mantia, Marco Arment and many others, as can be read in one of Michael Tsai’s masterful collections.² As well as, in my own humble and far less masterful writings (here and here).

It’s a beta

Let’s clear up a misunderstanding: constructively criticizing the beta version of an operating system, such as macOS, is a good and right thing to do.

When Apple releases a beta, they’re not doing us a favor by letting us preview an unreleased product. Rather, we’re doing Apple a favor by analyzing and dissecting their software in ways that might never have occurred to their official developers and testers.

To argue, as many do, that “you have to be patient, it’s just a beta” or that “betas always have bugs,” is utter nonsense, because it is precisely at this stage, when the product is tested in the field, that flaws emerge which official developers, accustomed to working on it every day for months, no longer notice.³

After all, if Apple has extended access to its Developer Betas to a much wider audience in recent years, it means that what is done in this phase is indeed useful to them!

The Wallpaper

The first thing you notice when you access your Mac after the update is the new default wallpaper, which now shows the rocky shore of Lake Tahoe, surrounded by a long chain of snow-capped mountains (in Nevada?).

I don’t particularly like these natural wallpapers; there are too many details that distract and prevent a clear view of what’s on the Desktop. However, compared to the anonymous wallpaper we had before (and which is still among the available wallpapers), this one is much better, so it’s all right. And the subtle ripple effect of the waves, which unfortunately isn’t visible in the screenshot, is truly delightful!

However, changing the active default wallpaper on the fly seems to hint some issues in the development direction of Tahoe/Liquid Glass, as will become even more apparent in the next section.

This, to be fair, is a change introduced in the previous beta, which I didn’t get a chance to write about here, yet. Apple has added an option to restore the menu bar background (System Settings > Menu Bar > Show menu bar background), just like in Sequoia and previous versions of macOS.

In my opinion, this is an excellent decision because, after using macOS Tahoe for a few weeks, I realized that having a transparent menu bar available is useless. For at least two reasons.

The first is that with a transparent bar, menu items and icons tend to blend into the background image, becoming much less legible. This effect is particularly severe when the wallpaper is full of details and gradients, as in the example below.

The difference in clarity when the menu bar has a background is evident.

The second reason is that, even if the menu bar is transparent, it cannot (rightly) be occupied by application windows, so you don’t gain useful space for applications.

What is the real purpose of a transparent menu bar if it is less legible and doesn’t provide more useful space for applications? It is just to achieve a (questionable) more homogeneous visual effect without any functional advantage?

Most people use their computers to work. They don’t spend all day admiring the desktop. Why should they struggle to read the menu items or the battery level, the Wi-Fi strength, and all the other icons that are there for a specific purpose, just because some dime-a-dozen designer decided that the menu bar should blend in with the desktop?

It is striking, though, that after no less than two Developer Beta releases, this setting has still not been translated into Italian and, I imagine, other languages. It is a small detail, but that gives the impression of a half-baked, thrown-together thing, something that the team working on this part of Tahoe is still not quite clear on.

This reinforces doubts about how Tahoe’s development is progressing, as expressed very well by Craig Grannelli.

[this change] also makes me question Apple�s confidence in its design work. When Apple starts hedging its bets, it signals that it knows something is wrong, but lacks the conviction to course-correct. Or perhaps such settings are a means to temporarily shut people up, while default choices reveal the true intent and direction of travel.

System Settings

In my first article on Tahoe, I reported that the new Appearance item in System Settings behaved strangely: setting the Auto mode in the section related to Dark, Clear, and Tinted icon (and widget) styles apparently had no effect.

In the article, I supposed that this mode would allow the operating system to automatically adapt the display details of the chosen icon and widget style to the active Light or Dark mode. However, I also noted that the implementation seemed rather confusing.

Actually, it wasn’t a poorly implemented feature; it was a true bug, as reported in the Release Notes for this beta.

Finder
Resolved Issues

Fixed: Finder does not display Dark Mode app icons or tinted folder colors when the Folder Color setting in System Settings > Appearance is set to Automatic. (152193702)

Unfortunately, even though Apple claims to have fixed the problem, I don’t see any improvement. However, I clearly see that certain combinations of settings still result in such low icon contrast that it becomes difficult to tell them apart.

The Finder

As soon as I opened the Finder, I had the impression that Apple had reduced the shadow intensity of the separate groups of icons that now make up the Toolbar.

Unfortunately, this is not the case; the shadow intensity, as well as the icon transparency, is identical to before, producing the same color mess described in the previous article whenever the more colorful icons in the main Finder window end up beneath those in the Toolbar.

To avoid this, it would be enough for the Finder’s Toolbar to retain the white background present since Big Sur (that replaced the previous metallic one). This way, the icons shown in the main Finder window would be visible only in that window, without spilling over into the area reserved for the Toolbar.⁴

The more I use Tahoe’s new-Finder, the more I wonder what’s the point of this confusion, where the Toolbar – which isn’t there for beauty but to manage files and navigate the file system – has to blend and overlap with the files themselves, in an indistinct mix that isn’t even aesthetically pleasing?

Even Apple’s developers seem to have doubts about their choices, as switching from Icon to List view shows the usual clear separation between the main window and the Toolbar (apart from the three-dimensional effect added to the latter by Liquid Glass).

If we switch to Column view, we find a third, intermediate mode between the previous two. In this mode, the Toolbar has a white background, but where the icons of applications and files are blurred well before they reach the Toolbar, as happens in the normal Icon view.

This confusion in the display mode of the Toolbar is not only present in the Finder but also in applications like Notes where, depending on the chosen display mode, you can find yourself with a transparent Toolbar that blurs everything that ends up underneath it,

or with a normal Toolbar with a white background, as we are used to seeing since Big Sur.

Something similar also happens with Font Book, albeit with slightly different modes, while it doesn’t happen with Freeform or Preview, which always have a transparent Toolbar. Reminders is another special case, but I’ll leave you the pleasure to figure out why.

In short, there seems to be a great deal of confusion in Cupertino, and even the developers cannot decide what to do with the new Liquid Glass-style Toolbar.

Application Icons

I want to give the new application icons in the Finder their own section because, in this case, it’s no longer a simple matter of taste, but of the relationship between Apple and developers. After all, developers are fundamental to the success of a platform.

But first, let’s briefly recap the issue.

In macOS Tahoe, Apple has introduced a new icon format for applications, borrowed from iOS. The new icons have the shape of a squircle, a geometric shape intermediate between a circle and a square, and can be created with the new Icon Composer. This new format allows, among other things, to dynamically adapt the icons to the chosen style, or rather Appearance (see the System Settings section).

So far, so good.

The problem arises from the fact that there is no choice: the icons of all applications installed on the Mac can no longer have a customized shape, such as that of BBEdit which I am using to write this post, but must obligatorily adopt the squircle shape.

All application icons that have not yet adapted to the new style imposed by Liquid Glass are automatically enclosed in a squircle with an horrible dark gray background behind them, which seems to be placed there specifically to flag those bad products that have not yet conformed to Apple’s new guidelines.⁵

But redesigning icons is no piece of cake. For example, Bare Bones Software, which is certainly not an indie software house, has not complied yet. Its flagship product, BBEdit, was given a major update just a few days ago, but retained its traditional icon.

Independent developers are even less enthusiastic about having to redo all their application icons following the new format imposed by Apple.

One of them is Howard Oakley, who ironically calls macOS Tahoe the iconoclast, and equates the squircle with the gray background to a sin bin, as the area of the field where a player who has committed a foul is temporarily confined.⁶ Someone else goes even harder and calls the squircle a true prison.

Even those who decide to comply have problems because, as Howard Oakley tells us, updated icons for Tahoe may not work correctly in previous versions of macOS.

Half of the applications installed on the Mac that I updated to macOS Tahoe have grey icons. In the month and a half between the release of the first Developer Beta and today, I believe none of them have adopted the new icon format. This includes Google Chrome, which certainly has the resources to adapt quickly. Some Apple applications, such as GarageBand and Xcode, don’t even follow their own guidelines. The latter is particularly significant given that Xcode is the main tool for developing Mac applications.

My impression is that Tahoe’s graphical interface is not carved in stone -� oops, in glass – and that developers prefer to wait for the final version before conforming to Apple’s dictates.

After all, between Developer Beta 1 and Beta 2, Apple has already changed the Finder icon due to popular outcry, and has added the option to restore the menu bar background. So it’s clear that Apple is not insensitive to the criticisms expressed by those who are previewing Tahoe.⁷

I almost forgot: you can even restore the usual oddly-shaped icons in Tahoe. However, it’s a manual and rather tedious process, that must be repeated for each affected application and for each Mac. I’ll pass.

Performance

The third Developer Beta of macOS Tahoe seems much slower than the two previous versions. For example, Firefox takes forever to launch and restore previous tabs, but almost all applications seem more sluggish, especially at startup, than is reasonable to expect on Apple Silicon. Some ‘System Settings’ panels appear completely empty at first and take several seconds to display the available options.

As annoying as it is, this is normal behavior in a beta, which by its nature is filled with debug code and immature or poorly tested functions that may generate memory leaks, erroneous cache usage, and the like. I only mention it here because the first two Developer Betas appeared much more responsive than this one.

In any case, restarting the system solves the problem, at least temporarily, while we await the release of the final version.

Conclusions

In a few days, perhaps even tomorrow, Apple will make the Tahoe beta available to everyone, so that it can be tested by a much wider and more diverse audience.

As I said earlier, the fact that the Finder icon was changed mid-development demonstrates that Apple is listening to criticism about the new macOS interface. So there is hope that other issues will be resolved in the two months remaining until the official release of the new macOS version.

If someone thinks that critical posts like those cited above, and maybe even the little notes you’ve just read, are written solely for the purpose of getting easy clicks… well, never mind, the authors will come to terms with it.

macOS Tahoe: see you in September

Sat, 28 Jun 2025 06:00:00 +0000

It’s becoming a habit. Earlier this year, instead of waiting, like I usually do, for the next version of macOS to be ready (or nearly ready) before installing the current one, I installed Sequoia on all my Macs. A few days ago, I decided to take the plunge and install the very first developer beta of Tahoe on a Mac that I don’t use much, mainly to try out the new Liquid Glass interface on macOS.¹

Since this is my first time trying a macOS beta, I cannot say whether previous versions were more or less mature than Tahoe at this stage of development, which admittedly is still far from the official release.

Therefore, I will share my first impressions of the new interface here, focusing in particular on the Finder, which is one of the most frequently used applications, and on System Settings, which is essential when getting familiar with a new operating system. After the official release in September, there will be time for a more in-depth evaluation.

Update

The update from Sequoia 15.5 to Tahoe 26 Beta weighs just over 7 GB, which seems in line with previous updates, and perhaps even slightly below average.

The installation of the new operating system is fast. I dont’t know exactly how long it took, but I was surprised when I found out that it was already finished.

After the update, the first thing you see is this screen, which gives a preview of Liquid Glass, with the buttons raised above the rest of the window. Here, there is no visible transparency effect yet, but there will be time for that, too.

Desktop and widgets

Once you click Continue, the Tahoe Welcome Screen appears, which, poor boy! looks like toothpaste writing overlaid on my Mac’s default background. Sadly, the days of the magnificent Welcome Videos of the early macOS versions with the big cat names are long gone.

From here, you go straight to the Mac Desktop, which now displays a few widgets on the left-hand side of the screen (some of the widgets do not show any information just because the screenshots were taken late at night, with an inactive internet connection).

I’ve never really liked widgets. On Tiger and later versions, I used a few, but only because they were neatly tucked away on a separate screen, the now forgotten Dashboard. Having them on the Desktop, which I use all day, just annoys me. I already know that, as soon as I finish this post, I’ll remove them without hesitation.

But there’s time for that. For now, I’m just going to change the wallpaper to Tahoe’s default.²

I’m not thrilled with the new wallpaper: there are too many details and gradients for my taste, and the contrast with light icons, such as the disk icon, is too low. But no one is forcing me to use this exact wallpaper, so this is a non-issue.

Finder

A true problem, however, are the application icons with the dark gray background, which literally make me jump out of my seat when I first opened the Finder.³

The original icons had a transparent background, which can be noticed simply by changing the background of the Applications folder in Sequoia or earlier macOS versions. For reasons beyond understanding, in Tahoe this invisible background is replaced by a dark gray tone, that is an understatement to define as ugly.

Clearly, Apple applications do not have this issue. However, as shown in the previous image, some of the most popular ones are affected by it, with Google Chrome being one of the main examples.

However, when I scroll down towards the less popular apps, I find lots of ugly icons bordered in gray! In some cases, the icons have even been shrunk, presumably due to the new dynamic scaling rules of Liquid Glass, making the gray area around them even larger. Who on earth came up with something like this?

This is not the only questionable aspect of the new Finder. Here, the familiar Toolbar has been replaced by separate groups of translucent icons that seem to float above the main window.

The change feels somewhat rushed, especially since they forgot to raise also the folder name. That said, the new toolbar can be considered acceptable, even if inconsistent, when there is a light background behind the icons (as shown in some of the images above).

But when the translucent icons of the Toolbar overlap the most colorful icons of the main Finder window (as shown in the image below), the result is a chaotic, unpleasant mix of colors, that makes it hard to tell one Toolbar icon from another.

Maybe using a stronger blur effect or reducing the transparency might help to avoid the issue. However, wouldn’t it be better to just stick with the old white toolbar, with the new floating icons on top?

And yes, I understand that everything must speak the liquid concept now, but was it really necessary to turn the cursor in the Finder’s status bar (the one in the bottom right corner that lets you resize the icons) into such a huge yet barely visible capsule?

On the other hand, the new Trashcan isn’t bad at all; it looks more modern than the classic cylindrical one we have always had. I do wonder how it would stand upright, but it is clear that skeuomorphism has been dead for a while now.

Still on the topic of the Finder: could someone explain why the Settings window in the Finder still has the slightly rounded corners from Sequoia, and why its icons look thinner than those in the sidebar of the main window?

The new Apps

The new Apps application, on the other hand, isn’t bad at all: it groups installed apps in a logical way, more or less as iOS already does. It definitely looks better than Launchpad, which I tried to use but quickly gave up on,⁴ though I don’t like the fact that it takes two clicks to access the apps in a given group.

Mission Control hasn’t changed, and I’m totally fine with that. I use it a lot, and I wouldn’t like to break my habits. The same goes for Chess, which I never play because I always lose, but that has been a part of macOS since… forever (and was present in its forefather, NeXTSTEP, too).

The other default applications don’t seem to have changed much either, but I’ll save a more detailed analysis for later.

System Settings

Lastly, a look at System Settings. I won’t to comment on how confusing it has become. Up to Monterey, a quick glance was enough to find what you needed. But ever since macOS started mimicking iOS, you basically have to rely on the search function every time you need to find some setting.⁵

What I will comment on is the new feature that globally changes the color of macOS Tahoe icons and widgets. Here you can see the Default icon (and widget) style which, aside from the grayish border I mentioned earlier, is what we have always been used to seeing.

This image shows what happens when the Dark style is enabled. While all the Apple icons visible in the Dock do change, the application icons shown in the Finder do not —- probably because they need to be updated to support this new style. However, the Light theme doesn’t really do this new style justice,

whereas with the Dark theme, it’s a whole different story.

However, if I enable the Dark style and select the Auto mode, the entire interface reverts to looking exactly like the Default style. You can see it in the two images below: the first shows the Mac screen with the Dark style and Auto mode enabled, while the second shows the Default style.

I assume that the Auto mode is supposed to allow the operating system to automatically select the styling that best fits the current Light or Dark mode. While this makes sense, it might need a different implementation; as it stands, it just ends up being confusing.

The other two styles, Clear and Tinted, are nice enough, but personally I don’t like the idea of having all the icons in the same colour. I’m sure plenty of people will appreciate these new uniform styles, but I doubt I’ll ever use them myself.

Even with these styles, the Auto mode automatically adjusts the appearance to match the active theme. Here too, I think that both the placement and the labeling of the automatic mode needs some improvement.

Not bad at all, the option to change the accent color of the user interface.

I’m not really into these things, but a lot of people like them, and since they don’t overhaul the interface, why not?

The final gem is the huge switch that toggles Bluetooth (as well as Wi-Fi and VPN). True, even in Sequoia these switches were larger than the others, but don’t you think Apple has gone a bit too far this time?

Conclusions (for now)

This ends up my quick overview of macOS Tahoe and its Liquid Glass interface. If I gave the impression that I’m not thrilled about it, well, that’s exactly how I feel.

I really appreciate that Apple had the courage to change, aiming to develop a consistent interface across all its devices. Liquid Glass definitely has a lot of potential, but it’s still quite immature on macOS, perhaps even more so than on the iPad. It reminds me of the metallic transition of Leopard, which needed several subsequent macOS releases to refine.

In any case, Liquid Glass is the future, and we’ll have to live with it for quite a few years. So it’s best to start appreciating its positive aspects now, and be patient with the negatives.

In the meantime, Apple’s developers have fixed the flipped Finder icon, which caused quite a stir. Hopefully, before the official September release, they’ll do the same for the many other oddities and inconsistencies.

On the iPad, Liquid Glass is very interesting, though still quite immature. ↩︎
Unless they’re really ugly, like some Linux wallpapers, I always stick with the default backgrounds. I’m not a fan of extreme system customization, and using the default wallpaper helps me to instantly recognize which OS version I’m running. Besides, macOS default wallpapers are almost always really beautiful. ↩︎
Actually, these grayish icons were already showing up in the Dock. But due to the late hour or the low contrast, I hadn’t really paid attention to them. ↩︎
For example, because it used to lose the carefully set layout and didn’t allow syncing it across multiple Macs. ↩︎
Some might suggest that having a similar layout between macOS and iOS is a good thing. Indeed it is, but unfortunately iOS settings have always been one of the most confusing things I’ve ever seen. Therefore, it would have made more sense to adapt the macOS settings model to iOS, instead. ↩︎
