How to Reset Amphetamine's Individual Preferences:

You can also delete an individual preference by running a command in Terminal. To get a list of all available values, take the following steps:

1. Launch from /Applications/Utilities

2. In a new Terminal window, enter the following command and press return:   


   defaults read com.if.Amphetamine

   You will then see a list of output like the following:


   "Allow Closed-Display Sleep" = 1;

   "Allow Display Sleep" = 0;

   "Allow Screen Saver" = 0;

   "Always Ask to End For Low Battery" = 0;

   "Hide Dock Icon" = 1;


   ... etc.

3. Find the specific preference name (in quotes) you are looking to reset and craft a new command as follows

   defaults delete com.if.Amphetamine 'preference name goes here'

   Using the example output from step 2 above, the command to reset the Hide Dock Icon preference would be:

   defaults delete com.if.Amphetamine 'Hide Dock Icon'

4. Quit Amphetamine

5. In a Terminal window, enter the command you just created in step 3 and press return

6. Restart Amphetamine
