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.

Try Settings > Desktop & Dock > Double-click a window's title bar to > Do nothing

See my other post explaining what caused the problem. In my case, it was a combination of Dell's DDPM software (precisely its EasyArrange feature) and updating to Sequoia.

@dialabrain Never assume everyone's using the exact same setup as you. (In my case, it was a combination of Dell's DDPM monitor software and the Sequoia update that caused this hard-to-debug issue.)

Thanks for this help. I hated this. The feature might be great, but dumb thing to make it default.

Love to customize things. But please, let us choose what we want.

Geeziz...!!! I couldn't find it because I couldn't describe it properly to a search engine. Thank you - it's been making me nutz.

@dialabrain It's a Sequoia issue in any case. Why would Dell's DDPM software start behaving differently from how it did for more than a year?

I'm not blaming Apple for this, but any major change can have inadvertent consequences.

The lesson to learn is to look at edge cases, too. It doesn't help telling people "it works for me and everyone else" when they might have different setups.

I disabled that as soon as I got this version. I have turned off everything that I can find and I still can't get my desktop windows to work right. I have no idea why Apple believes that the only way we will love their x-dates is by turning them on and not mapping how to turn them off. If this were an airplane it would not fly.

if you're running any form of 3rd party window tiling SW - e.g. Dell's DDPM utility that they distribute with their monitors - try uninstalling that and see what happens. That was the problem for a couple of us. Don't know if other tiling utilities might suffer from the same fate.

Good luck!

Wouldn’t that be nice if it was true. I am not the only one here reporting the issue. I rarely get the marquee. It just resizes. The whole 48”. I have tried always moving down first just to be sure it isn’t resizing as a result of hitting the top. Nope. Doesn’t help.

I did that long ago - but it did NOT help. For some reason my browser windows, Xcode windows, BBEdit windows suddenly "maximized" when I mistakenly dragged the windows too close to the top or left/right edge of the screen.

Only when I completely turned off EVERYTHING there ("Tile by dragging windows to screen edges", "Hold option key while dragging windows to tile" and "Tiled windows have margins") -- only then the dreaded "feature" seems to stop.

The thing is, I WANT to tile windows by going to the screen edge. I do NOT want them to resize to my full 48" monitor when I do it. The resizing behavior happens to me any time I try to move a window, whether it hits the top of the screen or not. Super annoying. I guess I will go back to Magnet - https://apps.apple.com/us/app/magnet/id441258766?mt=12

Jo!, try this App...

but how will an app that seems to do the same and costs money on top of that help me to get rid of the tiling al together? I want the 'old' function of option-klick the green button, which sizes the document to its size, and no more. That function has disappeared (see other post for screenshots)

Is there maybe a possible command through Terminal to switch this off??

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!

Hold the Option key while hovering over the green pill button and select the option to get out of that mode(?)

for your app window.

or as suggested above turn off the tiling features in Settings.

I tried it, but it doesn't solve the issue.
