I hope they release a version of these fixes on iOS 18 in a form installable on an iPhone 14; I've been trying to stay away from Liquid Glass until it's actually usable. I really don't want to be forced to upgrade, since Apple seems to have replaced UX testing with "just ship it," as has become standard in the industry.
I am a newer iPhone user (2 years now) and I am of the same opinion as you. I see so many people crying foul, that their phone is now unusable, but I’m just hear going “eh it’s uglier” and continuing. Curious what OP thinks is fundamentally broken.
Now I have heard about issues on MacOS and things but not really anything around the phone.
Indeed, based on all the “look at that, you can’t even read xyz” screenshots around release time I thought it will be really bad. Upgraded and…it’s fine. After a week you don’t notice anything and the old OS will look dated. Just like every design change and any product that causes a lot of noise in the first week.
Agreed that there are more rough edges on Mac, but even then, I've been using Tahoe for months now and it's been fine. I hear podcasters saying that they're just skipping the entire Tahoe cycle and waiting until this fall's OS and I just don't get it.
It's about 60% as usable. Weird and distracting jiggling makes it hard to target where the button will be.
Also the placement of buttons and functionality is completely scattered around the UIs, which severely reduces usability. What do all the mystery meat buttons do now? One has to relearn all the UX. There's a ton of improvement needed, it's about first-draft level quality.
Dark mode UI elements are almost invisible too, frequently.
It has a "my first redesign project" feel everywhere. On macOS I upgraded right away and it was a huge downgrade on performance. On iPhone I waited until 26.2, and merely had to suffer far lower usability.
They won't, it already didn't happen for 18.7.4 and 18.7.3 (only via beta channel for the latter), and the present fixes are being released as 18.7.5 for the iPhone XS/XR. Still I think that staying on iOS 18 is the lesser evil.
Liquid Glass looks pretty from a distance, but my biggest gripe with the design language is just how difficult so many things become to read or interact with. Given that the whole raison d'être of liquid glass is transparent effects, the options to limit that or otherwise increase contrast simply do not go far enough. I also balk at how much extra computing power is needed to generate effects I find no value in and would prefer to disable.
My hope was that Apple would be forced to course correct in subsequent releases but that doesn't seem to be happening.
> “My hope was that Apple would be forced to course correct in subsequent releases but that doesn't seem to be happening.”
I’m optimistic that they will eventually course correct on Liquid Glass, but we’ll have to wait until iOS/macOS 27, or perhaps longer.
There are parallels to Apple’s butterfly keyboard fiasco on the hardware side. Sleek looking on the surface but an objective step backwards in usability. Unfortunately it took Apple several years to reverse course on that one.
> There are parallels to Apple’s butterfly keyboard fiasco on the hardware side.
There are also parallels with the original pinstripes-and-transparency-everywhere aqua UI. I am also optimistic that it will be toned down over time but retaining the responsiveness.
My biggest frustrations with it aren't even related to the look of things, its the all around disregard for user experience. The new screenshot UX on iOS is an insanely bad downgrade.
I think it makes sense. They refocused it on sharing or extracting information from screenshots. Which is what people want more than saving them to the camera roll. Being able to copy text or translate the text in a screenshot is super useful.
They almost certainly will course-correct in the next release now that the culprit responsible for Liquid Glass is no longer at the company. But they won't chuck it out wholesale; it will be a gradual evolution back to sanity.
They reacted pretty quickly to the butterfly keyboard fiasco. By the time users received the shipping products of the first gen, the second gen were already in the pipeline so there was a slightly modified with only a dust cover being added. There was no third gen.
Hopefully iOS 26.x releases will continue to correct Liquid Glass, but I'm guessing iOS 27 is well down the path with it still integrated. Maybe iOS 28 will see sanity return???
Second gen butterfly keyboard broke a lot too. And then there was the no-esc touch bar, and the removal of inverted-T arrow keys... It took a few years of no good mac laptops before they backpedalled enough to get back to where they started
I’m pretty sure butterfly keyboard was made worse when it came to the hotter rubbing higher power Mac’s. I rarely saw folks with the original 12” low power model having issues.
It was not an entirely bad concept for the device it was conceived for, but Apple has a habit of unifying their technologies to all their products and sometimes, like with Liquid Glass, that seriously doesn’t work.
> I also balk at how much extra computing power is needed to generate effects I find no value in and would prefer to disable.
I mean, "computing power" in a literal sense maybe, but does that matter if it doesn't translate to either "workload contention" or "electrical power"?
I think the Liquid Glass effects, similar to smooth scrolling, are mostly just running as pixel shaders on a spare tile of one of the SoC's GPU's Streaming Processors — a tile that likely likely would have been idle-but-burning-power-anyway, given that GPU power management occurs on the level of entire SPs. It's the same reason that ProMotion "smooth viewport scrolling" doesn't really cost anything.
Workload contention. My iPhone 17 visibly struggles to render components with evident lagging - this is user-noticeable, if it were all done by an otherwise spare core I wouldn’t notice these things.
AFAICT, the steady-state Liquid Glass effects (think: the address bar in Safari, staying static itself while you scroll the page under it) cost nothing. That's what I meant above.
Animating the Liquid Glass widgets (i.e. changing their position or shape), on the other hand, does seem to cost a lot / produce lag.
I get the impression that this is down to the UI toolkit not being optimized for whatever Liquid Glass is doing in terms of recalculating constraints during animations. (When the GPU overruns its time budget while computing shaders for the compositor, the visual effect is of [double-buffered] texture buffers dropping/repeating frames, not slowdown. Actual "lag" in a GPU-composited UI is either from CPU work, or from one-shot CUDA-type GPU "prerender jobs".)
I get the sense that Apple rushed out some shitty code that has some of these components re-evaluating a bunch of their placement and sizing constraints on every non-static animation frame (rather than just giving the Liquid Glass shaders the ability to do declarative tweens.)
Or maybe the shaders already do declarative tweens, but Apple are doing tons of redundant on-CPU per-frame recalculations, to re-do any constraint-based layout for everything around the component during the animation, that might be impacted by the component's current tweened state. I dunno.
Either way, it's definitely silly, and could be re-engineered to work a lot better.
But it's also not really "Liquid Glass's fault" (i.e. something inherent to the visual design); it's just (AFAICT) bad implementation engineering, rushed to give Apple something to talk about besides its failure to launch Apple Intelligence.
While I'm really glad they've fixed a bunch of important security vulnerabilities, I'm really hoping they fixed the screen flickering issue [1] they introduced in macos 26. It has been driving me insane and even impacts my Studio Display. My work computer is locked to 15.7.3 and has no such issues with either the internal or external display (The same display flickers in 26).
Really wish Apple would get their software quality up from the gutter.
Is this related to the 'Screen Mirroring' problem?
When I connect my laptop to a projector, I can select an individual window, or at least I used to be able to select a window and just project that. However, now when I try to select the window, as soon as the mouse cursor gets near the selection button, the button disappears!!! It has been driving me absolutely insane.
A similar issue happens with Apple Silicon macs and external monitors since long time ago. A fix I found online [1] is to disable GPU dithering using the Better Display app.
The flickering was so bad in my case that the pixels got stuck for some minutes when it happened.
I tried that and many other things like changing the default color profile and it and it didn't work. A reboot fixes it for a few days before returning, so it definitely seems like a bug rather than a hardware issue. Both my work MBP (No issues, macos 15) and personal Air (macos26) are apple silicon.
I see flickering like crazy when I adjust the screen brightness on my M5 Macbook Pro on Tahoe.
But it's especially obvious when it dims itself based on ambient room brightness, I can actually see the vertical refresh happening as I move from a fully bright room to a dim one.
iOS also flickers every time I exit an app back to the Home Screen.
Weird green tints for no reason.. bubbles that take so long to inflate, you think your tap was dropped. Round edges that no longer fit the text content. Stupid ellipses at the edges of wrapped text. And all the functions that now take two taps when one used to do it. Text rendered on top of text for crying out loud! Whole view panes clobberin* each other. WebKit is a mess of wasted black bars where menus were hidden. Multiple flashes of white and black between content changes. It hits Apple apps as well as trashing third party layout.
Too many defects to list.

Apple celebrates 50th anniversary by burning down 40 years of human interface knowledge.
Careful if you're still on MacOS Sequoia, Apple has hidden Tahoe as a default under updates. If you click updated now it automatically upgrade you to Tahoe.
I believe it is new. I’ve never seen them:
- put a upgrade os version under “updates”
- then select the upgrade os version instead the current version when there are multiple updates ( os patch, safari or xcode)
I imagine scheduling lined up for the 26.3 release and it wasn't considered dangerous enough. They did this with 26.2 as well including a fix for a zero day. I wonder if they are leveraging that to get people to update sooner. Imagine some people might be turned off of updating with the bugs and visual changes in 26. It's not like 26.2 or 26.3 have any major changes that are enticing.
Maybe they can fix Messages from bugging out all the time. Apple software has gone down the drain. I don’t want a million new features I just want the ones that make a phone a phone actually work 99.5% of the time

This sounds overly dramatic. You may not like the design but its 100% usable.

It's usable. It is also noticeably slower on my iPhone 13, even after turning on "reduce transparency."
Reduce motion, that will help
Updated my 13 mini. Performance is fine / maybe better.. but battery. Tanked. How true is the ‘it takes days for reindexing’ statement?
They won't, it already didn't happen for 18.7.4 and 18.7.3 (only via beta channel for the latter), and the present fixes are being released as 18.7.5 for the iPhone XS/XR. Still I think that staying on iOS 18 is the lesser evil.
I recommend installing liquid glass on iOS. It actually has been looking good on there since 26.2. Macs have been godawful with liquid glass.
Doesn't look like it. It looks like it's only iPhone XS, iPhone XS Max, iPhone XR

Just go to Settings > General > Screen Capture, and turn off Full-Screen Previews - which fully restores the previous behaviour.
Personally I prefer the new behaviour.
But eitherways: it’s just an option.
The Windows ME/Fisher Price look. I can get past the drag handle problem. It's like every window is now the damn ios simulator.

It's a very complicated system. Performance issues are bad but they're not necessarily caused by how the UI looks.
You can report an issue by typing applefeedback:// into Safari if you want.
And even if they reserved a core, that would be a waste of a perfectly good core

Their previous security updates feature was mostly unused.
I suppose it’s not really working, or is the product of a team and no other internal team actually use it.

No problems with Messages here.
macOS was so buggy for me a few days ago that I updated my computer to the public beta. Boom, problem solved. So bizarre.
Do you feel an improvement in speed? My 32GB RAM M5 MBP is slow as molasses in Tahoe. My M1 MBA feels much faster (I haven't updated yet).
Now if they'd only fix—meaning remove—Liquid Glass and other nonsense that they've added, I could stop sticking to Sequoia..?
This one - I have seen some shit folks. This one is not good.
Now if they'd only fix the CarPlay issues, I really miss working navigation in my car.
I have called and opened tickets, and I keep hearing it'll be fixed real soon now.
