I Think You would have to buy a windows license and download Bovada on the parallels side in order to run the Hand Converter.
I have looked into the hole parallel thing but it really is a pain/lot of money to to get something so simple to review your hands, let alone a HUD. I know iholdem indicator works but that thing alone is $100 and it just is a HUD no hand reviewing. I have read about the card catcher by the same people that made bovadas hand converter but it only works in cash games right now and you still have to buy HM2 or PT4.
Mac Parallels : $20.00
Windows 7 license: $80.00
PT4: Just Holdem : $100.00
Bovada Hand Converter: Just Holdem: $16.00
Ace poker solutions hand catcher: just for cash games: $40.00
Pokeit free 10k of hands that can be reviewed: Free
Option 2 will probably be the way I go. Till some one comes up with a Mac/Bovada friendly option. If that ever happens. Pokeit is nice but I only use it to review specific hands that came up in sticky spots. I have only used it for a month and I'm almost maxed out my free 10K hands. I had the trial version of iholdem Indicator and it was nice but I have yet to pull the trigger and buy it.
If you or any one reading this do try Pokeit out please use this link: http://pokeit.co/signup/1cvXyE
