yosimite 10.10.4

Hi Chris
Hope it’s ok to jump into this post as I am having problems installing my MR 816x onto my MacBookPro 10.6.8, running Yosemite. This is a clean install from scratch and I was given the Firmware Updater V110-2 to install and when I try and run it, I just get FW device not found (MR is plugged in). The FW cable work fine on my other Mac with the MR. I even ran my original Tools for MR disk in Mac to see if that would work but installation failed right at end.

I don’t have another FW device to test connection on Mac but when you look in hardware list it just says FW Bus max speed up to 800 mb (no devices show up though).

If you have any advice that would be great, assuming that MR works with Yosemite ok?

thanks so much!
