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

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!)

You might try going into System Settings > Desktop & Dock. Under the Windows subsection, Turn off feature called, "Tile by dragging windows to screen edges".

I've had the same problem, tried the options in system settings but without success, as some other users report too. Then i noticed that I'm running an app as startup item called OneMenu.app, which i only use rarely for locking my keyboard when cleaning my mac.

But the app also adds window snapping, which I wasn't aware of. It triggers almost instantly when moving a window (the very annoying behavior other users report here). Macos integrated tiling (and tiling with Magnet.app for example) are way more precise and useful.

Maybe you're running OneMenu as well? Try to close it :)

Right after updating to macOS Sequoia my app windows began to snap to edges as soon as I click the title bar with the mouse. I've tried every guide available to try to disable this behavior, but no luck. Let me be clear, just by click & start dragging the window it immediately changes size and tries to snap to a predefined place, no matter if it moves close to a screen edge or the Alt key is being held or not.

There's no way to disable this function, and that's really annoying.

By chance, I found that the only way to move the window freely without snap activation is to hold Shift-Cmd while dragging it, but I've been unable to find where this key combination assignment in defined.

I didn't like this new feature either, and I was able to stop it by selecting System Settings > Desktop & Dock, and then under the Windows subsection, turning off the feature called "Drag windows to menu bar to fill screen". After doing this, I could still drag the window to the edge to tile it (which is fine) but it no longer fills the screen when I moved the window to the top menu bar (which is annoying). Strangely, if I close the system settings and then go back in again, that option is turned on again, but it doesn't seem to do it any more so hopefully it stays deactivated and I don't have to repeatedly turn it off.

Be sure to disable "Drag windows to menu bar to fill screen."

I don't see that one in some of the macOS 15.0 screenshots in this thread, but after I upgraded from Ventura to a later version of Sequoia, that one caused a great deal of unwanted behavior until I found it and turned it OFF.

this is not helping with external large monitor. None of the work-arounds suggested here help.

the only thing that helps me, is pressing SHIFT when dragging a window. But I can't change it to default behavior in settings.

this doesn't help - and none of the suggestions in this thread help, when using external monitor - snapping still happens there.

the only thing that helped is holding SHIFT when dragging a window - then it stops snapping.

But there's no way to set this as a default behavior.

Hold Down the " Option " Key and click the Green Button in the application

In addition to disabling the Tile settings, disable Stage Manager and Mission Control Spaces.

Do a restart and then log into the user.

Tried disabling all the features mentioned in this thread and restarting, but nothing worked for me on M3 mac. I have now come to peace with pressing "Shift" key while dragging..

that does not help if you want to DISABLE auto snapping

You are absolutely right

 Product Feedback - and make it known to Apple.

Maybe request they remove this new Feature introduced in macOS 15 Sequoia

I’ve already been trying all of this options, and nothing of them works as expected.

Then, perhaps the User's expectation are greater than what macOS 15.0 Sequoia can deliver.

Only and FYI for comparison purposes

Using 1 M1, 1 M2 and 1 M3 Application Silicone computers

Each were upGrading from Sonoma 14.6.1 to macOS 15.0 Sequoia

This function works as outlined by @Randall_2023

Ok, lucky you... ;-)

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.
