Razer Synapse macOS Big Sur Howto

# Razer Synapse Nightmare in a Hackintosh Big Sur 11.3.1 and 11.6.1
# Razer Keyboard, Razer Tartarus V2 and Razer Mamba devices.
# Next time going to other Brand devices. Sorry Razer your NO Support in macOS is too much too handle. So greedy.

# Install Razer Razer_Synapse_Mac_Driver_v1.87.dmg
# Do not reboot yet
# Open Terminal

# Commands in Terminal
launchctl load /Library/LaunchAgents/com.razerzone.rzdeviceengine.plist
launchctl load /Library/LaunchAgents/com.razer.rzupdater.plist

# Now you see Synapse Icon in Menu bar
# Open Synapse after some seconds a Exclamation Icon shall appear in the bottom right corner
# Update Synapse 187 to 188.20 It will take a while.
# Now reboot with the Original Synapse 1.87 Installation window. (You save a reboot with this)

# Now in order to Synapse be able to discover your devices you need to unplug and plug your devices. This sucks. Thanks Razer.
# Fixes: I found several fixes but some did not worked and others did.
