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.

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.

My brand new iMac came with Sequoia 15.3, and the automatic resizing has been driving me nuts. I would have returned the machine to the Apple Store, if I hadn't already let them recycle my 14 year old Mac. Thanks to this string, I was finally able to stop it by turning off the Tile by Dragging Windows to Screen Edges. How can this be the default setting???

As of Nov 13, 2024, "Tile by dragging windows to screen edges" no longer exists. It has been replaced by two control buttons; “Drag windows to screen edges to tile” and “Drag windows to menu bar to fill screen”. The button “Drag windows to menu bar to fill screen” is buggy in that it will not stay Off. When you close "System Settings" and reopen, it will turn itself back On.

Ever since I updated to Sequoia Verson 15.3.1 some days ago, the window will still expand when I drag the window upward. But I have already turned off "drag windows to screen edges to tile" function. It's time for Apple to do something about this irritating setting.

Do you by chance have 3rd party software that might cause this?


For example, "Dell's DDPM software has a feature called EasyArrange which allows, among other things, window tiling just like in Sequoia".

Tile by dragging windows to screen edges.


You can just choose to not use the suggestion. When the outline appears indicating which tile it is going to drop into, just move the window a little and the Tile will go away.
