What's the process for updating?

So I had a previous version of this driver installed. Do I need to uninstall 
anything before installing hte new version, or will the installed take care of 
everything?

It should normally overwrite the old version, unless it was a manual install 
and you copied the .plugin file yourself in your home library folder. 

To be perfectly you safe, you can manually remove the plugin from your MIDI 
Drivers (only the Casio one!) before installing the new driver. You cannot harm 
your system by having two versions of the driver installed at two different 
places, but the old one might be chosen before the new one by the system 
(depending on where they are installed), and therefore your keyboard won't 
work.

I see thanks. I did use the installer so it should be fine. The keyboard is 
working well.

Where do I find the MIDI drivers?

Removing old drivers would have had to be done before you used the newest 
installer. You no longer have to worry about it, unless you want to remove the 
current driver manually. If you always used the installer, there won't be extra 
copies of it on your system. In fact, since your keyboard works well, your 
installation is correct and doesn't require any more work.

For your information, the driver is normally installed at "/Library/Audio/MIDI 
Drivers". You can look into it to see which drivers are currently installed on 
your system. For instance, on mine, I have a Yamaha driver along with my Casio 
driver. However, the system also looks for MIDI drivers in 
"/Users/<username>/Library/Audio/MIDI Drivers". This is useful if you're 
testing (or developing) your own driver, and don't want to affect the other 
users on your machine. It also doesn't require administrator privileges, so you 
can just copy your new driver without entering your password.

Thanks for your detailed answer; I just see CasioUSBMIDIDriver.plugin there so 
we are golden.

Thanks.
