t2 will not show up on my mac or window 7

[darkspark]

I have tried to use this on both my mac and my windows 7 and it will not bring up the drive and it says that it does not support my car and needs to be updated. I ran this on my car 2 month ago.

on the pc can you look in the device manager and see what it shows?

Thanks
