Setup:
- Basilisk V3 X HyperSpeed on macOS (Bluetooth) and Windows (2.4GHz dongle)
- Synapse 4 on Windows, NO Synapse on Mac
Issue: Scroll wheel click stopped working at all on MacOS, and generates zero HID events on macOS, which I confirmed with the Terminal commands ioreg -l | grep -i razer, hidutil list, and sudo log stream --predicate 'eventMessage contains "Button"' --info. All other buttons work fine.
Reproduction: Mouse middle click worked on Mac yesterday morning. Switched to Windows PC last night after the Synapse update on 5/25 (typo for date in title, but it’s where I assume that Synapse took a hold of the mouse/updated its firmware). I switched back to Mac this morning, and the middle click is dead. Broken over both Bluetooth and the 2.4GHz dongle on Mac, but works fine on Windows 2.4 Ghz. Didn’t test Windows Bluetooth.
Already tried:
- Hardware reset (L + R + scroll click on power-on)
- Mac restart, update, safe mode
- Bluetooth module reset + plist delete
- Re-pairing
Conclusion: Since it breaks over both connection types and no HID events reach macOS at all, this looks like a firmware bug from Synapse writing a bad HID report descriptor to onboard memory. Windows is more permissive in parsing HID reports which is why it still works there.
Anyone else seeing this after the most recent update??
