If you are having trouble with your Mac clicking or popping, or having any other audio error that causes playback to stop, or not run smoothly please try all the steps below:
-Visit the downloads page and make sure you have the latest version of the Driver and MixControl software for your Interface.
-In Apple Menu > System Preferences > Network and make sure to remove any Network Adapters you are not currently using for Internet or LAN. Having ports you use for audio set to also be used for Networking can eat up their bandwidth which is needed for smooth audio streaming.
If you have a Firewire Interface make sure to remove any Firewire, Thunderbolt, Thunderbolt Bridge or Thunderbolt Firewire listings.
If you have a USB Interface make sure to remove any USB connected items, such as BlueTooth PAN, BlueTooth DUN, Android or iPhone connections, etc, as these devices are often internally connected to your USB Bus.
-In Apple Menu > System Preferences > Users & Groups > Choose Admin Account > Login Items and remove any Startup items.
-In Apple Menu > System Preferences > Energy Saver set Computer Sleep to Never. Make sure "Put hard disks to sleep when possible" is NOT checked.
-In Apple Menu > System Preferences > Security & Privacy > Firewall make sure Firewall is Off.
-In Applications > Utilities > Disk Utility select Macintosh HD and click Repair Disk Permissions. Repeat this for any other Hard Drives you have connected.
- NOTE: In El Capitan (10.11) "Repair Disk Permissions" is called "First Aid", so select First Aid and choose Run First Aid on your Hard Drive
RESTART the Computer.
-If you have anti virus software (e.g. Norton Anti-virus) please turn it off while recording.
-If you have Airport on for your Internet please turn it off while recording.
-If you do not have a Bluetooth keyboard and mouse turn off Bluetooth while recording.
-Close any unnecessary applications while recording.
If you are still having trouble with your Interface playing or recording audio cleanly please contact our Tech Support Team via the Contact Support Link.
