Got an M1 MacBook Air.
AT FIRST it detected everything, but cannot change the RGB settings or keybinds. Then eventually stopped working altogether. I do noticed that in the status bar on top, the Razer icon does appear and it shows all of my peripherals as well a the profiles.
So Synapse detects them, just won't work. I looked at my fiancé's MacBook and compared the two. Everything works on her MacBook. I then found the difference.
I noticed in System Preferences >Security & Privacy >Privacy >Input Monitoring, it is missing RzDeviceEngine.
Is there any way I can add that? I tried hitting the + | - and not sure how to add it to the list since I found the .plist but it needs to be a .app.
I tired @avaddon's solution but to no avail it does not work due to architecture incompatibility (M1 Silicone).
