Thanks to both of you for the answers. Maybe I'm wrong, probably am, but it seems that the PC version may have a few more features than the Mac version. I still have my PC with BIAB 11 on it and could upgrade to the latest PC ver but I would prefer to go the Mac way if there are no major differences. I have looked at the charts and am somewhat undecided. I would like to have the latest version, so I could wait until December for the PC update. Updating to the Mac version now would mean, in the long run, that I have to pay for two upgrades. I'm 78 years old and retired, so I don't want to spend money unnecessarily. I am certainly open to recommendations from those who are a lot more up on such things. Many thanks for reading my ramble. I look forward to your responses.
