Metabones + firmware = frustration
 

I just got the metabones speed booster EF to E mount. My Fs700 is on firmware 1.0 and because I'm on a mac I can't seem to make the firmware upgrade to 2.0 because my computer is in 64bit kernel.
How can I get these to work together? The lens I'm using is the 24-105 f/4 L.
I have tried to get my computer to boot in 32 bit mode and have done so but the firmware update software still thinks I'm in 64bit mode.
Right now I really don't need the 4k options and cannot send the camera out for a week or more since I'm booked steadily.
Any help would be greatly appreciated.

thanks
Kevin
