I've switched from pc to the terrible world of apples and thus I can't use FBT anymore, but I can live with that since I found a new lovely piece of software by synium that I'm using now and I could just import my gedcom file...
I'm wondering tough why there isn't a alternative to update the tree by uploading a gedcom file, shouldn't be that hard for it to check what's changed and then merge the 2 trees.
Our Family Tree Builder software doesn't have a Mac version yet.
We've received many requests for this, so producing a Mac version is definitely in our plans. In the meantime, you can wait until we have a Mac version, or continue to grow your tree online.
A tree can be built online on MyHeritage.com, using a Mac. If you have a tree already and it has been published into your own family site on MyHeritage.com, we can, at your request, flip a switch so you'll be able to continue editing your tree online on your Mac, with a browser.
Please let me know if you'd like that. You can also import an existing tree into MyHeritage.com via import GEDCOM, and then continue editing it online on the Mac. Let me know if you need assistance with this.
I am afraid not. You have not missed anything. MyHeritage is only equipped to upload from FTB, not from any other program. Thus you are stuck.
What you could do though (I know that this works, because someone else whom I know was having the exact same problem) is to install a virtual PC on your Mac. In this way, you can emulate a PC on your Mac. The emulated version will run a bit slower, but that should not bother you too much.
Once you installed a virtual PC inside your Mac, you can then install FTB inside your virtual PC, and you are back in business.
