Thanks, that worked.

Almost 15GB? Wow, that's big. My internet provider is going to love this. LOL

something new incoming

 

[Jbobby22]

I know people are just getting on this, but any early thoughts on stability?

 

[timemaker27]

nothing new in the Mail.app.

 

[flowrider]

Not available for me on my NcMP 7,1 - Intel❓ Tried turning off and tried all available options.

[Chazz12]

nothing new in the Mail.app.

I used the Help menu and found this, at least. Looks like they are going to add categories soon. Can't wait for it to be implemented on the Mac, too.

Can't wait to install it on my MacBook Air M3

Thanks, was wondering why it didn't show up!

Thanks, was wondering why it didn't show up!

It's because you have to change the setting from Sequoia Developer Beta to Sequoia 15.2 Developer Beta. I didn't see it too. But there was also no notification for the Safari TP update. The Safari update was found while I was changing it and then there was the red 1.

Update notifications for apps sometimes take days to show up in the AppStore even worse on iOS.

Looks different without time remaining and no download size. The icon is different because I am downloading two updates, I think. The Safari TP update was also suddenly there.

I just had to go to bed when I saw it. Now I am too exited to sleep.

Edit: Preparing updates 35 minutes... Last time it jumped from 30 minutes to zero in a second, but remained a while on 30.

Edit: At least 5 minutes later and still 35 minutes. Those time indicators are really stupid.

 

[Adora]

2 minutes later the 35 minutes were over and it also downloaded Safari TP very fast after that.

Interesting change, so previously if you clicked on a widget from iPhone it would display "Open [app name] on iPhone'. Now it straight up opens iPhone Mirroring.

Found the same. I am not getting Mail categories on my iPad either.

 

[be3h]

I think I'm stuck on this screen. Turned on ChatGPT Integration and now I can't use Siri at all for the past 2 hours. Anyone else stuck here?

Music app is stuck on syncing...

Music app is stuck on syncing...

May not be 15.2 specific, I have had a similar issue over the past 24 hours or so on my iPad running 18.1RC and MacBook running 15.1RC. (DFU'd and setup both from scratch just over 24 hours ago).
The iPad started syncing correctly around 3 hours ago, the MacBook started syncing about an hour ago.

 

[Adora]

I can't update or download already purchased or new apps anymore from the AppStore since the update. I read in the Apple forums people had this problem already with some 15.1 betas.

I never saw this before and am running macOS 15 since the first Developer Beta.

This comes also if the app had already been purchased.

I know people are just getting on this, but any early thoughts on stability?

It was pretty unstable upon updating but its a bit better now.

 

[haralds]

I know people are just getting on this, but any early thoughts on stability?

It is VERY unstable on my Mac Studio M1 Ultra, which had no issue with the previous betas. I hope they have a quick update on this. I am having a panic multiple times a day!

 

[nnwrrr]

Anyone else getting this when attempting to log in to ChatGPT?

My partner logged in just fine with his 13" Air M2, and I'm stuck with my 14" M3 Pro.

And when using even a free version, it just doesn't work anywhere, neither in Writing Tools, nor in Siri:

Issue is still here, unfortunately…

Quite upset, I use Apple Music a lot. And now at least a 2-week wait for a fix…
