Problem: The podium HDMI cable to my MacBook is loose; signal drops out; no signal
Solution 1a: If they are using a 2022 or newer MacBook (most full-time faculty are), make sure they are NOT using the USB-C to HDMI adapter. Instead, disconnect the adapter and use the HDMI cable straight into the HDMI port of the MacBook (right side).
Solution 1b: For Macs without an HDMI port, try a different USB-C to HDMI adapter. Notify AV Services afterward if this fixes the problem (the security tether will need to be replaced).
Solution 2: Escalate to IT Help Desk
Problem: My new MacBook video goes black, the projector drops out, and/or the display shuts off after only a few minutes.
Solution: Adjust your default battery settings to prevent the display from turning off.
-- For macOS 13 (Ventura): Go to System Preferences → Lock Screen, then change the "Turn Display Off..." timers to longer periods of time.

-- For macOS 12 (Monterey) and earlier: Go to System Preferences → Battery, then choose Battery in the left sidebar.
Change the “Turn display off after” slider to a longer period of time (the default setting is only 3 minutes!)
