Consolidated and adapted from Sam Kusnetz, “Prepare, Execute, Troubleshoot” (figure53.com/notes/2013-10-29-prepare-executetroubleshoot); luckydave, “System Preferences for Show-Mode Computers” (wiki.figure53.com/QLab+Hints+and+Tips); and numerous operator checklists. Last updated 23 March 2015.

This checklist assumes you’re running QLab 3 on Mac OS 10.9 Mavericks or later for sound and video playback. Most items on this list apply equally to show machines running other software as well.

Before First Tech

1 If the computer is used for anything other than your show (it’s a personal computer or in use for other shows), start by making a dedicated user account for your show, under System Preferences > Users & Groups. It should not be an administrator account. Give it a password. (If it’s a dedicated show machine, skip this step.)

2 On your show account, download QLab from figure53.com. Install all appropriate licenses.

3 Delete all applications and documents that you don’t need. Trash every application except QLab, System Preferences, Safari, TextEdit, the Utilities folder, and anything else you need for the show. OS X will not let you delete some applications. In this case, click on the application icon, type Cmd + I, and under “Sharing & Permissions,” change your privilege to “Read & Write,” then delete the application. Empty the trash.

4 Load your bundled show file onto the computer. Put the folder in the center of the desktop. Make sure it is the only thing on the desktop.

5 Remove everything from the Dock except QLab and System Preferences.

6 Turn off your internet connection. Disable WiFi and make sure you are not connected via ethernet.

7 Write the OS X administrator account password and the show account password on a Post-It note and stick it next to the trackpad (if a laptop) or at the bottom of the monitor (if a desktop computer). If the computer’s a laptop, put a black cover on it or tape over the glowing apple on the back with a square of black gaff tape.

8 Set your system preferences as described below:

System Preferences

1 Desktop & Screen Saver > Desktop: Set the desktop background to solid black. Turn off “Translucent menu bar.”

2 Desktop & Screen Saver > Screen Saver: Set the screen saver to never start. Disable all hot corners.

3 Dock: Check “Automatically hide and show the dock.”

4 Mission Control: Uncheck “Displays have separate spaces.” This will not take effect until you restart. Remove all keyboard and mouse shortcuts.

5 Spotlight > Privacy: Add the system hard drive and any external drives that you’re using for the show to the Privacy pane. Disable all Spotlight shortcuts.

6 Notifications: Drag all applications to “Not In Notification Center” and uncheck all options.

7 CDs & DVDs: Set all options to “Ignore.”

8 Displays: Uncheck “Mirror Displays.” Arrange your secondary display to make it difficult to accidentally move the mouse onto it. Uncheck “Automatically adjust brightness.”

9 Energy Saver: Set all sleep options to “Never” for both Battery (if a laptop) and Power Adapter. Uncheck “Put hard disks to sleep when possible.”

10 Trackpad: Disable all options in all tabs.

11 Keyboard > Keyboard: Uncheck “Adjust keyboard brightness in low light.”

12 Keyboard > Shortcuts: Disable all shortcuts.

13 Sound > Sound Effects: Set sound effects to play through Internal Speakers. Drag the alert volume to silent. Uncheck “Play user interface sound effects” and “Play feedback when volume is changed.”

14 Sound > Output: Set the output to Internal Speakers and drag the output volume to silent.

15 Network: Remove all network devices that you don’t need for the show (probably all of them).

16 Bluetooth: Turn off Bluetooth.

17 Sharing: Turn off sharing of everything.

18 Users & Groups > Login Items: Remove all applications from the Login Items pane.

19 Date & Time: Disable “Set date and time automatically.”

20 App Store [Software Update]: Disable “Automatically check for updates.”

21 Time Machine: Turn off Time Machine.

22 Restart the computer to make sure all preferences take effect.

3 Connect the audio interface (sound card) to the computer’s USB or FireWire port.
