how do I disable automatic window resizing in Sequoia

Since updating this morning when I move windows around on my cinematic display they JUMP to full screen if I even get close to the top of the screen. How do I make this STOP!

MacBook Pro (M3 Pro, 2023)

Thanks for confirming, @d.s.cobb! That's exactly the faulty behavior I had reported via Apple Feedback.

Here, it's a Mac Mini M2 Pro with a Dell UltraSharp 40" monitor (U4021QW). And that turned out to be the problem.


As suggested by Dell, I had installed Dell's DDPM software, and allowed it to open automatically on startup. That software has a feature called EasyArrange which allows, among other things, window tiling just like in Sequoia. I've never used it, though, and wasn't aware it was seemingly turned on (maybe it wasn't). For more than a year, it hasn't caused any issues.

Now that changed when updating to Sequoia. Don't ask me how this is possible, but the new macOS window tiling feature seems to have enabled the DDPM EasyArrange feature, with no way of disabling it.


From there on, fixing the issue was easy: Quit DDPM, and the nasty behavior immediately goes away. Go to Settings, Login Items & Extensions, Open at Login, and remove DDPM, so that it doesn't load on startup. Problem solved. This also explains why most people in this thread didn't encounter the problem the way I did.

Well, I can assure you, based on almost 40 years of macOS experience, that lately (last few years) some features ar shoved down our throat, some disappearing again after loads of complaint.

This one is not a bug I guess but intentionally put there, but I hope it is and it will be repaired in the next issue

Every new feature in the history of macOS has been "shoved down our throat." Stage Manager, Full Screen instead of Zoom, Mail non-columnar view, Mail preview links, Launch Pad, the Dock, and everything else that is new. I can't remember a single change that wasn't enabled by default. Even Desktop & Documents in iCloud Drive was defaulted to On in the Setup Assistant. Unless you pay attention while setting up, it will be enabled. That's how Apple rolls. You are just experiencing a feature you don't like. All the rest were apparently OK.

There a few posts that say Dell monitor software causes window tiling. Perhaps you have something installed that is doing it or re-enabling it. It seems the vast majority of users have no issues turning it off.

nope.

the monitor (second monitor) is just 'a monitor' and has no accompanying software (as far as I know). It just happens to be a Dell. however, the system does know how to detect that it is a Dell … . I don't know how it does that.

what you are also saying here is that the '+' in the green button should actually behave like it used to prior to Sequoia with alle settings switched off?
