Thanks for the welcome and sorry for not including the full thing: F64.0 - Transsexual. So no, it's not an upgrade and I don't think it's available for Mac :-) . As I said above: I can be a bit too scientific...
Is that "Starat se" Google translation of "Take care"? If so then word of warning: Czech <-> English automated translation is not to be believed as in 90% of the times it gives you something completely different. Correct translation of "Take care" would be "Měj se" but have fun typing that on non-Czech keyboard layout :-) .
However I found out that tourists coming to Czech Republic number 1 word they learn is "Pivo" which is unsurprisingly "Beer". And no, I don't drink alcohol so I can't recommend any specific for imports :-) .
