Locate the Command File:

• In Finder, open ZebraTester Folder and MacTuning subfolder.

• Double-Click the DoMacTuning.command script

Review the default (non-tuned) settings

• Enter "ulimit -n". Typically you will see: 256

• Enter "launchctl limit"

• Typically, you will see:

  • maxproc 709 1064

  • maxfiles 256 unlimited

Execute the Command File:

A terminal window appears.

1. Press Return to continue

2. Enter the superuser password (sudo root password)

3. The settings are displayed with the new values. On this particular system, which has already been tuned, the values remain the same. These values will be set to smaller macOS defaults on systems that have never had ZT installed.

4. The tuning is complete.

   1. Reboot the system.

Verify the New Settings

• After the restart, open a terminal window and enter "ulimit -n" and "launchctl limit"
