iOS 26.4.1 Update for iPhones is Coming Soon

[MacRumors]

Apple's software engineers are testing iOS 26.4.1, according to the MacRumors visitor logs, which have been a reliable indicator of upcoming iOS versions.

iOS 26.4.1 should be a minor update that fixes bugs and/or security vulnerabilities, and it will likely be released either this week or next week.

Last month, Apple launched the Studio Display XDR, and it promised to release a Medical Imaging Calibrator that enables the monitor to display DICOM medical imaging. 9to5Mac today reported that the feature has received FDA clearance and is launching this week, so perhaps there will be a macOS 26.4.1 update and/or a Studio Display XDR firmware update too.

The medical feature will allow radiologists to view diagnostic images in apps like Visage 7 directly on the Studio Display XDR, according to Apple.

These updates will come out ahead of iOS 26.5 and macOS 26.5, which are currently in beta.

MacOS 26.4.1 is needed more. Severe memory issues.

 

[fruet]

Tomorrow is the last day to Apple open iOS alt stores in Brazil. Maybe that’s the update(?)

 

[MrRom92]

No thank you. 26.4 will likely be the last time I update until the next major iOS release.

MacOS 26.4.1 is needed more. Severe memory issues.

Is your memory pressure (red/yellow)? Otherwise it should be fine. I been getting issues with "swap memory" lately, macOS it's using more swap memory on a 24GB ram laptop, with green memory pressure. As far of my knowledge macOS uses dynamic ram management, which is better than Windows, but I thought swap wasn't necessary unless if it's memory pressure it's yellow

I know it isn’t affecting everyone, but for some, our notification badges on Reminders aren’t displaying. I honestly rely on that throughout the day, every day. Hope this will fix it!

I wonder if this will be tied to new hardware. The new base iPad is apparently due in the 26.4 window, for example.

And we’ve seen Apple in the 26 cycle drop product compatibility updates with X.X.X updates rather than X.X updates (AirTag 2nd gen - 26.2.1, Studio Display -26.3.1).

Random thought:

The article mentioned healthcare (medical imaging). It would be nice if - when Apple’s AI is actually good and useful and secure - if Apple had a full suite of medical and health Apps on-device to help shorten the wait times and lengthy diagnostic processes one most go through when one has to visit an American hospital. If Apple’s AI tech and health/medical apps could make the iPhone into a gen-1 version of Star Trek’s medical TriCorder device, it could remove or reduce significant pain (ie: time investment and potentially cost) that comes in navigating an emergency room visit.

I took my father to the ER earlier in the year… sitting for 9-10 hours waiting and 1/3rd of that was waiting for diagnostics to come back and then be interpreted by a doctor who was dragging from doing a 12 hour shift. If Apple's iPhone could also do TriCorder functions, it could shave many hours off the visit and possibly cut several thousand dollars off the insurance bill. That’s a technology win that I’d like to see.

CarPlay is too sluggish with iOS 26.4, has a horrendous amounts of bugs, and it heats up my iPhone 17 Pro Max where I have to power cycle my device... all while I'm driving.
Also the camera app freezes whenever I open it from the lock screen to take a quick photo.

It's been terrible for me. Then when I do grab my phone, the notifications just flood the banner style.

I will update only if it fixes resident evil 4 3 and 2 other than that Apple can get bent. I hat the dosreguard on keep ing compatibility functioning even in .1 updates.
i despise apple for this. And don’t get me started on the age verification crap.

In MacOS 26.4, WindowServer results extremely high CPU and memory usage just in idle with no apps. if your Mac powers anything buy a 1080p monitor, you are affected. Spikes to 50–90% GPU usage when these apps are open in windowed mode and up to 50+GB of RAM.

Causing multiple restarts per day to clear, which is unacceptable. WindowServer is required to be #1 priority for 26.4.

26.4 broke the iCloud (CloudKit under the hood) notifications that many apps rely on to update cloud data. A pretty bad regression.

I doubt this is related to new hardware. 26.4 shipped with some fairly major bugs.

I'd expect this to address the broken Wi-Fi 7 connectivity with the N1 chip, for example.

Fingers crossed it does improve stability and such.

Because now the Neo is out and Apple can comfortably feel that they have a iPhone, Mac and iPad for most demographics.

They can no start focusing on tightening up their OS’s.

Because great hardware is useless without good software.

Plus as we’re suspecting some old models will be left out of the 27 releases, they need to make sure they leave 26 in a good enough state for this customers.

looking at the picture for this article on 26.4.1, i can't help but wonder:
are they gonna force pink on us everywhere this time ?
i mean, normally i wouldn't ask such a question, but it's apple ..
so common sense is not being used in UI design.

what it's gonna be this time ?
pink on pink to "better" differentiate between panels and the different UI elements ?
they've been doing that since bigsur already.
one could think that 6years would be enough for them to notice that this can't be looking nice.
but apparently not ..
and as others pointed out there's still the degraded legibility too ..


apple (so far):
35 years of "think different" (that was great).
15 years of "feel very wrong" .. worse and worse each release.

 

[Bryan Bowler]

I use Portrait mode on my iPhone camera every day and Apple broke it with 26.4. Plus a dozen other bugs effecting me as well.

Once I get a stable release, that’s it, no more updates for me. Apple has become extremely disappointing and I can’t count on them anymore.

We all know that the Eugenics Wars will come first.

That’s nice, but misleading as long as Apple doesn’t fix iOS similarly.

1. Safari taking 20-30 seconds to initially connect to any web (fine after connected)

2. Group messages w/at least 1 android user not being received until WiFi is turned off

If this AI (whoever it ends up being from) misses a red-flag diagnosis on a CT study like an ascending aortic aneurysm, who is responsible for the inevitable negligence lawsuit? There's always a risk of AI missing the mark and giving a false negative diagnosis, even if presenting signs and vitals seem benign.

Medical software companies have been working on things like this for years now. Still terrible. Don't let the flashy headlines fool you. They're all awful and rife with errors. If your hospital tells you your medical imaging is being read by AI, demand a board-certified radiologist read it before they release you or make any lasting treatment decisions. It's one thing for a radiology department to use it for triage and assistance (auto-measure lung nodules, aortic diameters, etc.), but actual interpretations are nowhere close to ready for prime time. It's one thing in outpatient settings where nearly everything is normal or near-normal. It's another thing when put in place at high-volume emergency rooms or cancer hospitals.

AI can't draw a human with 5 fingers consistently. Do you really want it making life and death decisions for you?

I've been suggesting Apple should spin off their health segment into their own company and work under the Apple umbrella. "Apple Health, Inc" for all I care. Just something to save us from the hell we're in with current insurance/healthcare.

I did not say I want AI in healthcare today.

I did not say AI was ready to be in healthcare today.

Of course I get what you are saying. In the near term, you are right.

I feel the same way about an AI on a car driving itself. I say to myself that anyone who trusts FSD cars has a deathwish. In 10 years, it might fine. But today, I would not trust it. Today Tesla is rightly fighting FSD lawsuits, defining the standard and scope for FSD liability.

In time, tech moves forward… it advances… improves… is iterated… is perfected.

Implicit in my comment is when I said >> when the AI is actually good, useful & secure << meaning when it works as intended and has 99% success rate. Meaning it is not good today. Meaning goodness will come in the future. Not today.

That will not happen with Apple ios27 in a few months…. Not with GPT-10… Not in 5 years. But maybe in 20. That speaks to AI general functionality becoming acceptable/ predictable / reliable/ repeatable /insurable /affordable. In healthcare it may take longer.

But when the AI is good and proven, I look forward to seeing it.

I am older. I worked in the auto industry before moving to tech. There was a time when early anti-lock brake systems on cars were publicly decried as unsafe. The way they activated seriously frightened drivers and caused other unintended and sometimes deadly accidents, creating new liabilities for automakers. And their early fail rates were not anything to be proud of. But in time they were perfected and now they are unquestioned.

I don’t want today’s AI to serve me not even a cup of coffee. I don’t want AI making a life and death decision for me today.

But when the tech is perfected, I look forward to seeing it. When the tech can safely turn a 10 hour wait in the ER into a 3 hour wait because it makes an overworked MDs job easier… or because it improved back-of-house admin operations…. I look forward to seeing it.
