# How to uninstall Razer Synapse 2 ( https://www.razerzone.com/synapse-2 )
# on OS X (10.11-10.13) (El Capitan, Sierra, High Sierra)
# without using Razer's official uninstall tool.

# Tested on OS X 10.11.5 in July 2016.
# Edited with additional steps for later OS X versions,
# contributed by commenters on this gist.

# Step 1: In your terminal: stop and remove launch agents
launchctl remove com.razer.rzupdater
launchctl remove com.razerzone.rzdeviceengine
sudo rm /Library/LaunchAgents/com.razer.rzupdater.plist
sudo rm /Library/LaunchAgents/com.razerzone.rzdeviceengine.plist

# Step 2: Remove HID kernel extension.
sudo rm -Rf /System/Library/Extensions/RazerHid.kext
# OS X High Sierra: (Thanks to @DanThomson)
sudo rm -Rf /Library/Extensions/RazerHid.kext

# Step 3: Manually delete Razer Synapse app from Applications in Finder

# Step 4: Delete Razer files from "Application Support" folders:
sudo rm -rf /Library/Application\ Support/Razer/
rm -rf ~/Library/Application\ Support/Razer/

# Step 5: Synapse sometimes leaves a certificate installed in your Keychain.
# To remove it, open Keychain Access and click on My Certificates.
# The certificate will be called Razer USA Ltd, delete it. (Thanks to @MTCoster)
# There might an item called RAZER_KEYCHAIN_ACCESS. No certificate,
# but I suppose if you want to get rid of EVERYTHING Razer,
# you may as well go ahead and delete that too. (Thanks to @blueExcess)

# Step 6: Remove additional Razer-related files in /Library/FrameWorks
sudo rm -rf /Library/Frameworks/RzAudioSettings.framework/
sudo rm -rf /Library/Frameworks/RzSkinToolkit.framework/
sudo rm -rf /Library/Frameworks/RzStorageSDK.framework/

# Step 7: Restart your Mac.
# Expected results:
# - The Razer icon should be gone from the OS X menu bar now, and also not pop up sporadically either
# - The two processes "RzDeviceEngine" and "RzUpdater" should not be running when you check ActivityMonitor

thanks

Awesome sauce

Found some more remnants of this software even today (sorry I don't have time to update the original gist):

~/Library/Preferences/com.razerzone.RazerSynapse.plist
~/Library/Preferences/com.razerzone.RzUpdater.plist

thank you!!!

Thank you! Worked on BigSur.

Thank you for this!
I am using a mac for the first time in years, synapse was truly awful and put me off using any razer products on this device.
This guide solved my issue of random green text saying "profile" appearing on my screen constantly.

Also I am using monterey and this worked, for all its worth.

Thank you, I was struggling to get rid of it for some time. Worked first try!

thank you, very usefull !

What a cancer from an application - I have a feeling that it was ported somehow and not made for mac... You SAVED me from a trully terrible piece of software. People talk about malware and stuff like they are some kind of a mythical thing - RAZER SYNAPSE IS A MALWARE - don't ever install it on a mac.

Thank you.

This finally did the trick for me, it was really annoying at this point to always have the icon in the status bar left over even after uninstalling. Thanks a lot!

Thank you, this helped me out even to this day. Will never uninstall a no longer managed app. Seems razer pretty much left Mac devices in their own realm
