I ordered the new Razer Naga V3 Pro, and it showed up yesterday.
I was disheartened to see that it's not recognized in the Razer Synapse for Mac software (Version 4.0. [removed by moderator] ).
So I decided to use a technique that I've used with previous Razer mice that have onboard memory.
I'm posting this here on the chance that it helps some of you.
The only major downside is that you need access to a Windows machine that can run the current Razer Synapse software. Luckily, I have an old laptop that works great for this.
Connect the Razer Naga V3 Pro to the Windows machine.
Install/open the Synapse software on that Windows machine.
Use Synapse to configure all of the mouse buttons, scroll wheel & tracking options.
These settings will automatically be saved to the onboard memory of the Razer Naga V3 Pro.
Connect the mouse to your Mac and all of your settings should be present and functioning natively.
A bonus discovery that I made yesterday: I have discovered that you can use the Windows key modifier as the Command key (⌘) on a Mac.
I believe that USB sees this as a generic GUI key, which you might recognize if you've ever programmed a QMK keyboard.
I have successfully set up these three keyboard shortcuts on the mouse and they work beautifully on my Mac with no other software needed.
⌘ [ (back)
⌘ ] (forward)
⌘ ` ( I use this to cycle through windows in the active application hundreds of times every day.)
All I had to do was choose the symbol in Synapse and then add the modifier of the Windows key.
To be honest, I was surprised at this discovery (as I didn't expect it to work). That said, I'm ecstatic that it is working flawlessly.
So until we get a Mac Synapse update that supports the Razer Naga V3 Pro, I am sticking with the above, it is as it is a fully functional workaround.
I hope that helps!
