How to turn off automatic window resizing
I have been more than frustrated with MacOS Safari some some time after the last few recent updates - not sure how long ago, but well before the latest OS update (Mac OS 15.xx - Sequoia) Have looked and looked for answers to this question - but everything refers to a tablet or iPhone - plus are very dated. Found this one (same) question in the Apple Forum dated 2/8/2022, but no answer - now I have found the answer and hopefully it will help others.
The fix is simple - at least it has proven to be for me. I have two monitors connected to my Mac Studio - and have not tried this with one monitor - so not sure how they are affected - but this should work.
- Open System Settings
- Click on Desktop & Dock
- Scroll down to "Windows" (right above the "Mission Control" block)
- Turn "Off" (slider to the left) "Drag window to menu bar to fill screen"
Once I did this, Safari windows quit expanding and filling the monitor screen, forcing me to move screen lower to get it back to the original size.
Hope this helps.
