Symhony I/O

Why are the input and output level/volume popup indicators not showing up?

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.



Symphony I/O Firmware Updater stuck, hung, frozen at 4%

On some USB 3.0 equipped Macs, the Firmware Updater will freeze at 4% and never complete the update.

To work around this, you need to use a USB 2.0 port. This can be a USB 2.0 port on a peripheral hub, Apple keyboard, or monitor display.


Here are some steps to try to update your Symphony I/O:

1. Quit the Firmware Updater and power down the Symphony I/O

2. Connect the Mac side of the supplied Apogee USB Cable to a USB port on a monitor display, Apple keyboard, or external USB Hub

3. Power on Symphony I/O and run Firmware Updater ( be patient it can take up to 5 minutes to complete )

4. If your Mac does not have a peripheral connected that has a a spare USB port then you can also do the Firmware update from an older Mac with USB 2.0 as a last resort
