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
