Positive Grid Spark Mini USB interface nonfunctional in Tahoe 26.0

I'm trying to record with a Positive Grid Spark Mini amplifier and USB interface. Previously, the interface offered a pair of audio ins and a pair of audio outs. Since upgrading to Tahoe, the inputs are not visible in either Audio MIDI Setup or Logic Pro.

Screenshot from Audio MIDI Setup below.

MacBook Pro 14″, macOS 26.0

Yeah, this sounds like a macOS Tahoe compatibility issue.

A few quick things to try:

Unplug the Spark Mini and reconnect it after the Mac fully boots
Try a different USB cable/port (some cables only do power, not data)
Check if Positive Grid has released a firmware update for Spark Mini
Go to System Settings → Privacy & Security and see if there’s any blocked driver notification
Reset Core Audio (or just reboot again)

If the inputs don’t even show up in Audio MIDI Setup, it’s usually a driver/firmware issue with the new OS. A lot of USB audio interfaces break temporarily after major macOS upgrades.

If nothing works, you may need to wait for a Tahoe-compatible update from Positive Grid.

Is there any update on this? As of today 22nd November 2025 this still isn’t resolved. Just wasted so much time troubleshooting this.

Any solution to this problem? My Logic Pro does not recognize Spark Mini

Thanks! Not that it’s welcome news, but I’m glad to hear anything at all.

Though the interface functionality is hosed, the rest of the Spark Mini is still pretty awesome, it’s just not an all-in-one solution to get sound into Macs anymore. Plug its line out into some other interface and you can keep going.

Thanks for sharing.
