A few macOS betas ago, a bunch of sites started failing to play video for me in Safari. Disney+, Netflix, YouTube and some other sites will sit at a black screen for a few seconds and then give me an error. Sometimes it works, sometimes it doesn't. Sometimes certain videos will reliably fail while others reliably work fine. I thought this was related to Safari's autoplay protections, but I tried giving permission to autoplay all videos and that doesn't seem to change anything. Not sure if that fits the definition of a Snow Leopard update. If so, Apple needs at least a few more Snow Leopard updates at this rate. I'd also like to see them fix the issue where Liquid Glass uses a downscaled background image even at the most transparent setting. (Except for Siri AI which they seem to have added a special exception for, exactly because the pre-downscaling is super ugly)

Hey sorry to be the debugging guy in the comments, but maybe your network issues could be related to iCloud relay? I’ve had similar issues
troupo•58m ago
> an understated update that in other years might have been called a “Snow Leopard release.”

No. It wouldn't. Snow Leopard was two years in the making, and then took another few years to actually become the Snow Leopard people remember.

Fixing some transparency and re-drawing a few icons is not a Snow Leopard release.

Like, which features in this 150000-character blog post actually warrant the title of "Snow Leopard release"?

I imagine the author saw this release as "macOS Tahoe but not sucky"

I liken it to Windows Vista and Windows 7. Although fundamentally similar operating systems under the hood, Windows 7 smoothed out Vista's kinks and brought forth additional polish.

When was the last time you felt excitement for a macOS release?

Me? Snow Leopard.

When I transitioned to Linux I rediscovered OS excitement. I'm on KDE Plasma now and every update has exciting features that serves my interests.

If only KDE actually paid attention to UX and maybe cared about the looks and consistency a bit more. I'm sorry for being blunt but their visual design people's have no taste...
mikae1•41m ago
There's little margins and whitespace and this bothered me like hell before making the switch. It's funny, now I kind of like it. A lot is happening too. The latest Plasma had a very high degree of polish IMO.

It's far more consistent than Windows 11, but you have to pick Qt/KDE software, not GTK/GNOME for that to be true. I always choose the more KDE native option.

This is wild from a "tech" site. I used to read their articles fairly religiously, but this bent by their writers and commenters is really telling, and a signal to start looking elsewhere.

edot•42m ago
Continuing the quote gives more context, which I agree with:

"The obviously AI-generated flyers that come home from school with my kid or that get circulated around neighborhood groups strike me as benign but deeply tacky; the kinds of AI-generated images that get passed around by politicians online don’t even have the benefit of being benign.

More than anything, I’m just tired of seeing it everywhere, tired of being on the lookout for it, tired of it polluting every stream of information I have access to. Wasting time actively trying to avoid auto-generated slop is now a daily fixture of my life."

Obviously, one should be able to entertain an idea without necessarily accepting it, and much like any tool that can be misused, just because some malign actor (or dumb actor) uses it "wrong" doesn't mean you should also not use it.

"...Golden Gate needed a whopping 17GB more space on the M1 MacBook Air, thanks to a mandatory multi-gigabyte language model download that kicks in automatically the first time you connect a freshly restored Golden Gate Mac to the Internet."

This is the main thing stopping me from updating iOS/macOS. It's completely unacceptable to park a bunch of space on my devices right when that storage is at its most expensive it's ever been.

My phone is on iOS 26, and even with Apple Intelligence turned off, there's ~13GB made unusable. My phone ran out of space while recording a bike trip, and yet the model I have no use for remained.

For me, macOS 27 was great for the first 3 betas, then it became horrible. And the release version still has some weird bugs, even iOS 27.

It's as if their Claude credits ran out halfway through

I've found today after going to MacOS27 (I skipped 26 fully) that Chrome extensions don't load properly. They're super, super slow. I've found one or two other bug reports of this from older Dev builds but that's it. Bizarre. Time to flip back to Safari I suppose.
glimshe•28m ago
Will I get prompted to give Chrome permissions to the Local Network on every update? This is literally the one feature I'd like from Apple because I'm happy with everything else. The update looks cool, but nothing I actually want/need.

I wonder how many years we're going to have to suffer through this sort of insufferable virtue signaling as if even researching and outlining using AI is somehow the root of all evil.

Did he use the web at all? Hate to break it to him, but if he uses Google he probably tainted his work with some AI. The horror. I wonder if he used spelling and grammar correction?

Maybe he wrote everything out long hand at a local library using a quill pen and an 1878 version of Webster's Dictionary.

therealmarv•19m ago
Hmm, I remember when Ars Technica macOS reviews were the gold standard. This one isn't bad, but I miss having more in-depth information about the improvements.

In my opinion, the details here complement the Ars Technica article nicely:

Thanks to the OpenCore Legacy Patcher who show that not supporting old devices is a choice made by Apple.

I've been pleasantly surprised with Golden Gate. It's fresh-looking, works well, got rid of a lot of the ugly flat stuff they did over the last few releases (pre-Tahoe), supports more hidpi modes that make my work machine better...

But honestly, I don't think the average person should feel excitement for an OS release; boring means it just works and they don't have to learn a bunch of new features and different ways of doing things.

Telaneo•32m ago
I'm stuck trying to figure out what new stuff they could add. Sidecar was neat, but I never need it. I'm very happy on Cinnamon on Linux, which is probably less featured than KDE (haven't daily driven it to confirm), which just confirms I don't actually need or want user-facing new features. I need stability.

I think Apple realise this. There are no genuine new OS features to be added, so they just shuffle things around so that things are changing and thus seem fresh and hip. For anyone who cares about stability and doesn't want to relearn everything they shuffle around, this is nothing but a negative, but Apple et al. have no other levers to pull (well, there's the AI lever, but that's also generally not a positive in and of itself).

Maybe there are new OS features that could be useful, but creating and integrating them in a way that's actually helpful is just such an ordeal that nobody will do it.

A functioning window system would drastically enhance OSX productivity.
cosmic_cheese•15m ago
Window management (and indeed, desktop environments in general) are rather subjective I think. As someone who's been using Macs in some capacity since 1996 I'd be upset if macOS suddenly resembled a traditional Windows desktop or tiling WM thing, and the absence of Mac-like desktops on Linux (no, GNOME and elementary/Pantheon are not that) is one of the primary factors keeping me from switching.
thefunnyman•9m ago
Window management got better in Mac os but only recently with the addition of window snapping. You could do it before, but you had to drag from the green stoplight button which was an annoying mouse target vs the entire top bar.

Personally I do like the windows approach where there's a bar at the top with a few preselected zones you can use that shows up when dragging a window but the state of things on Mac os now is fine enough that things like that can reasonably be left up to extensions.

What exactly do you miss about the Mac desktops when using gnome's? For me the only thing I've noticed is lack of independent desktops per monitor though Windows also suffers that deficiency.

elAhmo•6m ago
Someone who does need a window system can use many of the hundreds of tools available, or use something custom. Regular uses don't really care about window management systems.

>OS excitement

Debian+KDE here. It's what I use to get away from OS excitement. I miss the 90's when nobody ever updated anything, and if they did it was on purpose and not something that happened behind your back.

For example, the other day Google "updated" the clock/alarm/timer app on Android with pointless and annoying changes. A clock app does not need an update, ever.

"But..." No! /usr/share/zoneinfo handles that. Stop it.

detourdog•15m ago
Snow Leopard is right up there with System 7.5.3 for me. I’m happy with their current OS trends compared to the flat OS trend of the past decade. They definitely need detail work and I think they default to turning features on that I would prefer off. Many of the new features I don’t use come off as a spastic GUI.
cosmic_cheese•11m ago
Snow Leopard was solid, but when I went back and used it I was surprised by how I missed some little bits of polish that'd been added since.

My ideal would probably be Mavericks 10.9.5 with the Leopard/Snow Leopard 2D grid virtual desktop model hacked back in. The linear version of Spaces that's been in place since 10.7 is needlessly simplistic.

elAhmo•7m ago
Well, it is easy to be excited on a system that is lagging on features.

It's not to write the article. I would hope they don't do that; I wouldn't want to read it.

But I do want them using it to help them research, find interesting contrary views on a subject, gut-check assertions (how many weirdly wrong statements in articles would have been caught by feeding it to an LLM and asking it to question unfounded or incorrect claims?), check technical accuracy of things outside the writer's core domain, track interview transcripts, search/summarize across prior work, do data exploration of public/government reports. Etc. It's a very empowering tool for journalism!

Instead, it's become a religious issue that is more or less at the level of "one drop" theory.
