Several Apogee products have pop-up level indicator graphics that will appear on the desktop of your Mac when the input and output levels are adjusted from the device or from the Mac's keyboard volume buttons.
If the pop-ups aren't appearing, there are a few things to check:
Launch 'Apogee Maestro 2' from your Applications folder, click on the 'Apogee Maestro 2' drop-down desktop menu and select 'Preferences'. Confirm that the 'Display pop-ups' checkbox is checked.
If you don't see this option, then pop-ups aren't available for the product you're using. If you've confirmed that the 'Display pop-ups' checkbox is checked and you're still not getting the pop-ups, try the following:
- Unplug/replug your Apogee device
- Restart your Mac
- Launch 'Activity Monitor' (Applications Utilities 'Activity Monitor'), click the 'View' drop-down desktop menu and select 'All Processes'. Type 'apogeepopup' in the searchbar in the upper right-side corner of Activity Monitor. Once you see 'ApogeePopup' displayed in the list, highlight it and force-quit the process by clicking the 'X' button in the upper left-side corner of Activity Monitor. Wait a few seconds and you should see the popups again after adjusting input/output level.
*Note for Duet Firewire and Ensemble Firewire customers*
There was a known issue with pop-ups not working for Duet Firewire and Ensemble Firewire when using any version of Mac OS 10.8. It is recommended that you use either a version of Mac OS earlier than 10.8 or later than 10.9.
