How to disable automatic window snapping / resizing on MacOS 15.0 Sequoia

Since Sequoia, my Mac behaves badly. I move a window around and suddenly it becomes full size. Then I resize it again, move it to the center and the size is changed again. It is EXTREMELY annoying and not predictable. Apparently it's some auto snapping brought in from iPads (where it somehow could make sense) but for a normal mouse/keyboard user it's breaking the Apple Human Interface Guidelines. It's irritating, confusing and not even logical.


Thats not how I want my mac to be. I have searched for a button or option to disable this but I have found nothing. The only option would be to downgrade which is a major task.

MacBook Pro (M3, 2023)

Do you happen to have an external Dell monitor? I had the same problem on a MacMini but not on two MBPs. Very strange! But I tried killing the DDPM helper utility for controlling Dell monitors, and then my window snapping issue was solved! There seems to be some clash in technology here. Both systems implement snapping, and disabling it in both places doesn't help. You have to stop the Dell app.

(If you still want to use the DDPM app, for brightness, contrast, etc, then turn on window snapping in that app. Perversely it results in no snapping!)

In my case, a Mac Mini M2 (2023) and also upgrading from Sonoma. The 3 options outlined by @Randall_2023 (and many others in every forum I've checked) are disabled, but still the snapping happens as soon as I start dragging any window.

Each computer is different from the other


Each user's configuration is unique to the user


Each use's computer will have uniquely combinations of installed Third Party Applications which is not common to all


So, attempting to add weight to this question " (and many others in every forum I've checked) " does not do it in this specific question

The reference to many others (posts) in every forum was not intended to weight anything, but just to state that the solution posted here using the mentioned options are the same posted in every other forum I’ve checked.


Anyway, it seems that this discussion is not going anywhere. This Sequoia feature does not work in my computer for whatever reason that I am not going to find here.


Maybe a future OS update will fix it… or not. Thanks anyway for your time.

I've turned off "tile by dragging windows to screen edges", restarted my computer, and still it retiles.


It's highly annoying when I need to have multiple windows from different applications in order to do my job (and no, I can't just use one application–it's all part of the workflow. One window are notes using an internet browser, one is Adobe Bridge, another is Photoshop, and I also need to see what's happening in Slack)


I think this is a bug that needs to be fixed by Apple.
