Hey all - I just came to a sad realization. I have an older Mad Catz RAT 7 mouse that has really old drivers that the new owners of the company won’t update. So I figured I’d try installing it in Catalina annnnnd it’s not compatible.

I checked on Mojave - the installed application and driver are 64-bit. It gave me a warning about trying to install it into the system. I’m guessing this has to do with the system folder being read only now. Anyone know how we’re going to get around this? This mouse requires this driver and I’m not going to give up on my mouse...

EDIT: tried disabling SIP, no dice. It still says “this application is trying to install software to the system drive and is incompatible with this version or macOS” or something to that effect. this is really stressing me...

Ugh this is infuriating! I have disabled SIP, even enabled and logged into the root user, and tried to change the permissions of the kext using chmod 755. Why won't it load the kext?

Okay! So I got the kext installed to /Library/Extensions instead of /System/Library/Extensions. So that takes care of the permissions problems.

Now there’s this:

Any ideas?
