Congratulations, so glad to hear you are up and running happily.
Quite a learning curve but that is usually the road most of us go down at one time or another, frustration and worry and finally success.
Don't forget to back up all your drive to a separate hard drive or similar so if anything goes amok with your computer none of your info will be lost.
A very important move for Family History buffs.
Enjoy your Mac and your work.
