Like, calling for people to get fired levels of hate. — Meanwhile, I'm pretty happy with it. I do hope Apple gives devs and users some options by final release, especially for accessibility, but beyond that, I like the direction. Wesley Hilliard / @hilli.tech : ah, I see we're back to “taking screenshots in very specific situations that make Liquid Glass an illegible mess.” — It's not that I don't get the sentiment, it's not ideal, but also, it doesn't always look like that? Like, I have to specifically line up elements to make them unreadable? … Mastodon: Marco Arment / @marcoarment@mastodon.social : Apple should've held Liquid Glass back until next summer, after much more internal testing and editing. — How are we supposed to design our apps for a constantly moving target? — How are *they*? @viticci@mastodon.macstories.net : Pocket Casts for iOS 18 on the left, Apple Podcasts for iOS 26 on the right. — Between the illegible glass and the tab bar that disappears on scroll, I honestly have no idea who can take a look at this and say “Yes, that'll do it. That's good.” — Liquid Glass is a mess so far, *especially* on iOS. … David Harrison / @david@cosocial.ca : @marcoarment At this point, I'm considering delaying my iPhone replacement this fall so that I don't get forced into this mess. I bet I'm not alone. This could really hurt their fall launch. — The good news is that if this does go really badly, that could be it for Alan Dye. John Gruber / @gruber@mastodon.social : If you can see the blue backdrop through the envelope, what's in the envelope (which is sealed)? This icon doesn't need tweaking, it needs to be started over. — [image] John Siracusa / @siracusa@mastodon.social : I'm just picturing the future explosive popularity of TikTok videos explaining the “secret settings” that make “the new version of macOS” more readable. You guys... @simonbs@mastodon.social : This is the most convincing “Liquid Glass is a disaster” post I've seen. If Apple sees this and still doesn't make major changes to Liquid Glass, they've completely lost the plot. — https://mastodon.macstories.net/ ... Louie / @louie@pdx.social : I've never seen Apple struggle so much during a beta release cycle. They have no idea what they're doing, and they're letting everyone in on that. It's not a very reassuring look. — I previously thought Apple couldn't possibly ship without Liquid Glass for ego reasons alone, but I'm starting to wonder if they just might revert, because it—quite predictably—shows no signs of improvement. … Louie / @louie@pdx.social : Basically every industry professional is sounding the alarm, huh. Either Apple didn't know Liquid Glass was bad or they didn't think it would go over this poorly. — Either way, it feels entirely preventable. The risk is huge. The payoff is... infinitesimal. … Steve Troughton-Smith / @stroughtonsmith … : Thing is, there is no point along the slider between 0 and 100% opacity where Liquid Glass is ‘fixed’. If you're a developer, you can try this in code. You either have Liquid Glass, with all its issues, or you have an opaque bar — there's just no leeway for this lensing/blur effect Sean Heber / @bigzaphod@mastodon.social : Been using it for a few minutes in the simulator and the glass in iOS 26 beta 4 already seems like a bit of a disaster which is saying a lot because it wasn't without problems in beta 3. — There are some aspects that feel slightly better in ways I can't quite pin down, but it's worse in other situations. … @marioguzman@mastodon.social : OH MY GOD THIS LOOKS FUCKING AMAZING!!! — /s #macOSTahoe #AppleMusic Beta 4 — I love not being able to read the now playing track info. — [images] @Sonikku@techhub.social : @andreitorres @nileane @viticci meanwhile in Mail. Invisible controls on bottom. — [image] Marco Arment / @marcoarment@mastodon.social : I don't think we're that lucky. The forces that got Dye there in the first place haven't changed direction — he has only *risen* in the ranks as people above him have left. — I bet Dye is invincible until we get new leadership above him, which is just the CEO now. — And you know Cook wont do shit. … @viticci@mastodon.macstories.net : legibility is so back 🙃 — (the last screenshot is the Photos editing UI when trying to crop a screenshot. LOL.) — [images] Dr. Drang / @drdrang@fosstodon.org : I think everyone misunderstands the purpose of Liquid Glass. But I've been able to divine Alan Dye's reasoning: — Opaque and nearly opaque bars and buttons are readable, but they obscure what's behind them. The great breakthrough of Liquid Glass is that it obscures both the button and what's behind it, evening out the UI in a way that's never been done before. @viticci@mastodon.macstories.net : “Library” — [image] X: Holly / @anxiousholly : liquid glass notifications [image] Jake Perry / @itsjakeperry : @markgurman You can't tell me this is legible [image] Holly / @anxiousholly : in iOS 26 beta 4 the lock screen wallpaper gets darker when viewing notifications [video] Quinn Nelson / @snazzylabs : Can we stop acting like the iPhone mini was some tragic failure caused by a few Twitter pundits? Apple does massive market research, and the mini wasn't a failure—it was one of the best-selling phones overall. Worst-selling iPhone? Sure, but so is the Plus that replaced it. [image] Mark Gurman / @markgurman : My perspective is Apple spent three years working on a UI and shouldn't throw it away over a week of Twitter posts. (Not that the UI is perfect). That's how we ended up with an iPhone mini that nobody who said Apple should make one actually bought or would recommend. @vnchocotaco : Beta 4 fixed a lot of bugs [image] Andrew Clare / @andrewjclare : iOS 26 Beta 4 is OUT NOW 🔥 WHAT'S NEW?

Context & Ripple Effects
Apple had already reduced Liquid Glass transparency in the prior iOS 26 beta after complaints that the interface was harder to read. Beta 4 reverses part of that retreat, showing Apple is still tuning the visual system rather than treating the earlier change as final.
The adjustment comes before iOS 26 reached public beta, while hands-on coverage later found the design could be both visually striking and distracting. That makes this a consequential test of how far Apple can push a shared interface aesthetic without undermining usability.
First-order effects
- iOS 26 beta 4 testers receive stronger Liquid Glass treatments again, while Apple reopens the legibility and accessibility trade-off that prompted the beta 3 rollback.
- Apple’s design team gains another developer-beta cycle to judge whether restored effects work across iPhone and iPad interfaces before broader distribution.
Second-order effects
- App developers preparing for iOS 26 must validate their own content and controls against a moving visual baseline, particularly where transparency affects contrast and readability.
- The reversal raises the likelihood that public-beta feedback, rather than a single social-media response, determines the final balance; the subsequent public beta rollout expands that feedback pool.
Third-order effects
- If repeated beta changes become the norm, major mobile-interface redesigns will be increasingly shaped by rapid public usability testing rather than a fixed design reveal.
- Liquid Glass illustrates a durable platform-design tension: a cross-OS visual identity can simplify product cohesion, but it must remain adaptable when it clashes with accessibility and everyday task completion.
The trend: Apple’s iOS 26 testing reflects a broader shift toward iterating prominent platform-design changes in public as designers balance distinctive aesthetics against usable, accessible interfaces.
