user1795: I used to run bitcoin on Ubuntu and I have a wallet with 1 coin in it.
I took a backup of my ~/.bitcoin directory which includes a wallet.dat file.
Now I'm running on a mac, using the bitcoint-qt client.
How do I get back the money from that wallet?
Can I just copy it over the existing wallet that the mac client generated?
Is there a way to run a command line client and point to my wallet then transfer coins from it to the new wallet?

user1795: I got it to work by simply copying the file over.
An important point to notice if you intend to follow this suggestion:
My mac wallet had 0 coins
If your mac wallet has coins, then don't follow this solution.
First I shut down the bitcoin-qt client. Not sure if this step is necessary but I think it's safer.
Then I copied the wallet.dat file over to 
~/Library/Application Support/Bitcoin/wallet.dat

Then start the bitcoint-qt client again. It might take a bit longer to startup than usual. Don't panic and let it take its time.
Then you will see your coins in the client!
