Why is there a short wait if you press a button on your headphone remote or your AirPods to pause the music? Because the interface has to let a bit of time pass to figure out if you’re going to press the button again, making it a double press (advance to next track) instead of a single press.

This kind of disambiguation delay is everywhere for simple gestures.

Why is there a short wait if you press a button twice in that situation? The double press processing also has to be delayed, because there is a chance it might become a triple press (go to previous track).

Why is there a short wait if you press a button to go to the next track on your car’s steering wheel? It’s a delay of a different kind, but the same principle: the function cannot kick in on press down, because press down and hold mean “fast forward.” So, software has to wait for button up event to go to the next track (which feels a bit slower than button down), or for enough time to pass so we’re certain it’s a button-down hold rather than a slow press. Here, both interactions experience a penalty for coexisting.

The most infamous of those disambiguation delays exists in mobile browsers. Since every double tap can zoom into the page ever since that famous 2007 iPhone presentation, every single tap on a link or elsewhere has to be delayed by about 300ms. This has been a source of contention since it does make the web feel a bit slower, and today browsers suspend double tapping on sites designed for mobile, trading zooming affordances for higher interaction speed – after all, you can still zoom in by pinching. But if you always wondered why older websites tend to be a bit sluggish to interact with, now you know.

Different tradeoffs are possible. In the Finder, clicking on icons isn’t slowed down even though double clicking exists, because selecting an icon is compatible with opening it! So in effect it’s not a choice between a faster A and a slower B – it’s A or A+B.

Even in the iPhone presentation above, you can see the interface highlights the link on double tap, to at least make it feel snappier, at the expense of the highlight being “wrong” and potentially distracting – or even confusing – when you end up double tapping. (You can imagine smartphones pausing on the first remote/​headset button press, too. It feels like it would be compatible with advancing to the next track, but I think it might also feel too “choppy,” too chaotic, in practice.)

Lastly, why is there a short wait if you press a button on your hotel TV to increase the volume? Oh, I think that one is just sluggish for no good reason.

Column view cut its teeth on NeXT computers…

…and blossomed on early versions of Mac OS X…

…but where I thought it really shone was the first iPods:

This was perhaps the most fun you could ever have navigating a hierarchy of things; it made sense what left/​right/up/down meant in this universe, to a point you could easily build a mental model of what goes where, even if your viewport was smaller than ever.

It was also a close-to-ideal union of software and hardware, admirable in its simplicity and attention to detail. This is where Apple practiced momentum curves, haptics (via a tiny speaker, doing haptic-like clicks), and handling touch programmatically (only the first iPod had a physically rotating wheel, later replaced by stationary touch-sensitive surfaces) – all necessary to make iPhone’s eventual multi-touch so successful. And, iPhone embraced column views wholesale, for everything from the Music app (obvi), through Notes, to Settings.

Well, sometimes you don’t appreciate something until it’s taken away. Here are settings in the iOS version of Google Maps:

I am not sure why the designers chose to deviate from the standard, replacing a clear Y/X relationship with a more confusing Y/Z-that-looks-very-much-like-Y. They kept the chevrons hinting at the original orientation – and they probably had to, as vertical chevrons have a different connotation, but perhaps this was the warning sign right here not to change things.

I think the principle is, in general: if you’re reinventing something well-established, both of your reasoning and your execution have to be really, really solid. I don’t think this has happened here. (Other Google apps seem to use standard column view model.)

I feel macOS these days starts feeling like Windows in the 1990s where occasionally some core component of it breaks, and a reboot is necessary to restore it to full functionality again.

But even with that in mind: this happened literally right after the reboot, with nothing much happening and no other signs of the system in distress.

It’s hard for me to even understand what would make this kind of thing pop up. Trash feels like one of the core tenets of a GUI – like undo, or copy/​paste, or windows gaining focus. You don’t expect it to just… stop working, especially with a circular error message like the above.

A few thoughts after reading Gruber’s take on Finder and its new auto-sizing columns:

1.
Column view as a concept and when done well deserves to be in the UI hall of fame. It flew and still can fly high in the Finder, and it was the unsung hero of both the iPod and the iPhone. It’s really fun to fire up NeXTSTEP 0.8 in Infinite Mac and see its first incarnation.

2.
Apple decided not to ship the auto-sizing columns a few years ago, hiding it under a “defaults write” incantation as a sort of a beta, but then seemingly just launched it this year without any changes. There are some charitable explanations – perhaps the beta was hard crashing Finder and the released one no longer does? – but in the current zeitgeist I’m feeling that it’s something more like this: the people with taste who were stopping it from getting launched in the bad state were either sidelined or are no longer there.

3.
And it is a bad state. It’s a first draft made public. Like anyone who deals with layouts learns over time, things like this one need careful min and max widths to have certain good pleasing and stable visual rhythm. They might even need a scale or a grid on top. And the fact that the width accommodates only visible objects doesn’t seem to make sense. The top hand doesn’t know what the bottom hand is doing, and it feels the feature is incompatible with itself.

This feels like an old Unix windowing feature, a sketch of an idea for GUI nerds who get excited about just the cool concept alone, ignoring the execution. Although, to be fair – this is opt-in and buried as the last checkbox inside a pretty obscure window. This might still be GUI nerd territory.

4.
So Apple really did think we’re going to love Liquid Glass, huh?

If you plug in a CD drive (he said with a straight face in the lord’s year 2026), and then eject too soon, the system offers this dialog, which allows you to say: Eject whenever you’re done with whatever you have to do.

But more modern media, like SSD drives, don’t show that window. The best case scenario is that you get a dialog box like the 1990s never ended:

It gets worse. Often, you get zero help in identifying what the “programs” actually are. (The word on the street is that it might be stuff like Spotlight indexing, which you can’t really control.)

More often than not I just click Force Eject or jank the drive cable out, which feels really unpleasant. I would guess many people do the same.

So at this point we are two steps worse than the original CD experience, which… wasn’t even that great! A pretty clear improvement on this already exists elsewhere in macOS, and could be reused here – “hey, you don’t have to do anything, just give me a second while I finish up here.”

(Can’t help but notice the discrepancy of visual styles of these windows, and even the inconsistency between calling things “applications” vs. “programs.”)

Fun little story by Bruce Horn on folklore.org about the original Mac and how modes are sometimes good:

We went to quite a few stores in the week or so after the introduction, and found that, without exception, every Mac’s floppy disk had a garbage name! They were all named something like ”;lkakl;rt;klgjh”, as if someone had just randomly typed characters to see what would happen. Which is exactly what they did.

In the Finder, the startup disk would appear on the desktop, in the top-right corner, ready to be opened. The Finder would initially select it; once selected, typing would replace the current name, following the modeless interaction model that I had learned in the Smalltalk group from Larry Tesler. This meant that whatever anyone typed when they first came up to the Macintosh would end up renaming the disk.

On the early Mac, just typing with any item selected renamed it, which caused all sorts of trouble.

The eventual solution for renaming that survives until today was: click to select and then click again to rename… but don’t click too fast, because that’s double-clicking, and that means something else. Windows, starting in Windows 95, did something similar, but also put rename under F2 – so at least you didn’t ever have to wait.

I liked the emergent behaviour from some graphic apps which put rename under ⌘R. It’s not that hard to make Finder work that way – see below – but I have always been curious why Mac or Windows didn’t steal this solution.

(Added later: People reminded me that of course Enter also renames, and does so immediately. I wonder why it slipped my mind in this context – possibly because in any other list or similar place, Enter would be the equivalent to opening? Maybe I’m discovering in slow motion how unusual Finder can be in its details compared to conventions we established after.)

John Gruber (twice) on macOS Tahoe rounded corners (previously), with a nice bit of archeology:

It was, I’d argue, a small mistake for Apple to stop putting a visual affordance in the lower right corner of windows to show where to click to resize the window. It was a bigger mistake to change the scrollbars on MacOS to look and work like those on iOS — invisible, except while you’re actually scrolling (by default, that is — savvy Mac users keep them always visible). The removal of the resize indicator happened long ago, in Mac OS X 10.7 Lion, released in July 2011.

I can recall at least one place in macOS where you can still see the resize grabbers – it’s in column view in the Finder.

I still think sometimes of old Windows where all the 8 affordances for resizing were clearly visible. I know Windows 3.1 was generally kind of ugly, but I liked how they aligned with the title bar and the buttons:

By the way, don’t love Gruber’s “Dyehoe” thing in the title. Feels Trumpian.

This appeared when trying to delete (even when trying to Delete Immediately, skipping the trash altogether):

Same thing right after, when trying to tag some existing items, for which I don’t imagine any new space should be necessary:

Also, why are these dialogs so different?

I feel like not so long ago there were literal books making fun of bad dialogs like these.

I am starting to collect all the problems I routinely find in Finder. I can think of ~15 off the top of my head; maybe this will turn into an essay of sorts. I hope this isn’t too boring for you.

Sometimes Finder takes a really long time to update the list of files after something changed it.

All my screenshots go to a specific folder. In these videos, you can see me taking screenshots with ⌘⇧4 while looking at the folder where they arrive.

The first one is fast – just as fast as it should be. The ones after that arrive with a few seconds of delay that feels completely random.

But this is nothing compared to this, just a few minutes later, where the delay was over 50 seconds. Nothing changed. The computer was not under load.

This happens routinely and feels completely random.

There is also, as far as I know, no way to force a re-sync with a keystroke or a button or a pull-down gesture, which could be at least a way to manually alleviate the symptom (if not the cause).

Hearing what others told me and based on prior experiences, I don’t have high hopes for any of this, but I want to be a good citizen. So I am filing bugs with Apple for all of these. I do not believe I can link to this directly, but the report I filed for this one is FB21444299.
