MacOS – How to permanently disable resume on El Capitan

macosresume

Notice: This is not a duplicate! Other questions had to do with older versions of OS X or had to do with temporarily disabling resume.

El Capitan has made my iMac very, very slow. A hard reboot should clean the slate so I can recover from OS hangs, but now windows and programs that were open when I shut the iMac down (with the power button) are restored to their previous states.

How can I disable this completely? I do NOT want to have to select a button every time I shutdown/restart, which is something I cannot do if I use the hardware reset.

Best Answer

There is a simple method for this, for anyone using Lion+.

Navigate to /username/Library

Cannot see Library Folder: While in Finder > Press and Hold OPT key Down > under GO Menu> Select Library

Once there, you will see a folder named Saved Application State

To disable ALL resume states,

  1. right-click on Saved Application State > Get info
  2. select Locked checkbox

To disable SOME resume states

  1. right-click on Saved Application State/Sub-Folder Name > Get info
  2. select Locked checkbox
