Studio Display Update Issue Fixed as Apple Addresses Code-Signing Issue

by

Yesterday, MacRumors reported on a growing number of Studio Display owners who were unable to update their display to iOS 15.4, and now, less than a day later, Apple has resolved the issue which originated from the software being unverified by the servers.

As highlighted on Twitter and confirmed by MacRumors, iOS 15.4, the latest software update for the Studio Display, had been unsigned by Apple as of late last week, making software updates for the display impossible. A few hours later, Apple resigned iOS 15.4 for the Studio Display, making software updates for customers once again possible.


The Studio Display does run iOS 15.4, and that's currently the latest software update for the display. While it does run iOS, updates for the Studio Display do not seem to be coordinated with typical iOS and iPadOS releases.

Apple released iOS and iPadOS 15.4.1 for iPhone and iPad users last month, but the Studio Display remains with iOS 15.4. Apple has promised an update for the Studio Display that addresses poor webcam quality but has offered no timeline on when the update would be made available.

So Apple forgot that the display runs iOS when they stopped signing it? Ooops.

I still think it’s weird that a monitor runs iOS.
It needs the whole iOS just to control the webcam and speakers?

Not sure why reviewers say the camera is bad. Everyone that calls me on it compliments on how good it looks especially with Center Stage and portrait mode turned on. I detect a lot of user error in these complaints / bad reviews!
I am super supportive of the Studio Display, and I was aware of the camera issues before I bought it, but I can confirm that it really does look like crap, at least from my view. Is the view better on the other end? couldn't say. but looking at on the Studio Display looks really bad, as in super noisy.

No!!!! Apple made a mistake so that means the display is trash!!!! Or at least that’s what I got out of that thread LOL.

All in all not an unreasonable turn around for an update nobody urgently needed.
Totally! People seem to forget Apple is still run by humans, mistakes get made.

Thank god MacRumors forum users immediately went completely ape **** when this issue was first reported on, lamenting over how nothing Apple makes ever works anymore, how Steve Jobs would turn in his grave if he were to witness Apple's current state, and how the twenty five Apple products they reluctantly already own are all terrible. That was really important.

It has an A13, so it's far easier to port over iOS rather than write a whole new 'displayOS'. I'm guessing Centre Stage mandated iOS being used.
