Yeah I am looking at the right library and there is definitely not a bitcoin folder there.  also, I unhide all files using the terminal, tried the searchbar, and still no wallet.dat file.  Any other ideas?  This seems really odd

New OSX user here.  I downloaded bitcoin and received .05 btc from faucet today (I can see it appeared as a credit when I run bitcoin).  However I cannot find a wallet.dat file anywhere on my computer. 

I searched through the FAQ, wiki, and forum and the only reference I was able to find for locating this file was that it should be in ~/Library/Application Support/Bitcoin/... but I don't have a Bitcoin folder in my Application Support folder and am unable to find wallet.dat anywhere on my computer. 

I do have a bitcoin-0.3.20.01 folder on my desktop, but do not see it in there either.

Thanks in advance, big supporter of the cause!
