If you are having issues playing back audio from your Mac, or hearing strange clicks and pops in your recording, you may need to optimise you Mac settings for audio.
Please follow all of the steps below:
- Increase the buffer sample size in your DAW settings; lower buffer sample sizes can cause clicks and pops in audio playback.
- Disconnect any unnecessary USB devices from your Mac, as these will share the same USB bus as your SSL 2 / 2+.
- If using a USB hub, please ensure it is an externally powered USB hub. If you're not sure, try plugging your SSL 2 / 2+ directly into the USB port on the Mac, and see if it resolves the issue.
- In System Preferences > Users & Groups > *admin account* > Login Options, remove any startup items as applications running in the background could affect your Mac performance. Once you've done this, restart your Mac.
- In System Preferences > Energy Saver set Computer Sleep to Never. Make sure "Put hard disks to sleep when possible" is not enabled.
- In System Preferences > Network, switch off Wi-Fi, Airport, Bluetooth etc, and see if this resolves the issue.
- Close any unnecessary applications - these drain your computers CPU resources, and can affect performance.
If the issue occurs only with recorded audio (as opposed to playback from Spotify / Apple Music etc) and none of the steps above resolve the issue, it is possible that the gain control is too high for your input source.
