Open/Save dialogs on my Mac (macOS 10.14.1) delay about 0.5 to 1 seconds.

How do I change this delay to zero seconds?

  • It's super annoying huh. Animations are not always user-friendly...

You can change the speed of the Save/Open dialogs with Terminal. Enter this into Terminal to change the speed to the default:

defaults write NSGlobalDomain NSWindowResizeTime 0.2

Change the number at the end to speed up or slow down the animation. The following is practically instant:

defaults write NSGlobalDomain NSWindowResizeTime 0.001

This is not specific to the open/save dialog however, it reduces the time of all animations on the system that read this value.

  • Thank you. I believe the actual issue is that macOS for some reason experience a noticeable latency of actually accessing the disk. Even on a modern machine with SSD. Nov 16, 2020 at 23:13
