Latest Windows TI downloads are 5.1.1
Latest Mac downloads are 5.1.3
After you Mac users installed the 5.1.3 version, when you switch on your TI, does it say 5.1.3 on the machine screen?
I mean...the internal software also changes?
I ask 'cause If you need to switch the Virus from mac to pc...you could have to downgrade-upgrade each time...and this is ANNOYING AS HELL...if that's the case...
