Synapse 2.0 Mac - Stuck in loop downloading to /private/tmp/.Razr/.Emily

Hi,
Anyone come across this issue before? Synapse 2.0 for Mac keeps looping an update and installing it but never actually completes the update. I am using an OrbWeaver Chroma with a MacPro 2012.

I have trace the files being downloaded to /private/tmp/.Razr/Emily ... The files being downloaded but not installed are:
1382944720rzrmodGamingKeypadWOWAddOn.zip
1511334776rzrmodOrbweaverChromaOTFPlugin.pkg
1517209923rzrmodOrbweaverChromaConfigurator.pkg

I have given full disk access/accessibility to RzEngine, RzUpdate and Synapse app. Rebooting the Mac and re-installing Synapse 2.0 have not resolved the issue.

Cheers,
Joe
