Bitcoin-QT client shows coins, but cannot find wallet.dat It's been a couple years, and I opened my bitcoin-qt client.  It says I have coins, but is taking days to "sync with network".  

Further, I cannot find a wallet.dat file anywhere on my system.  

How can it know I have coins without a wallet?

I'm on the same computer I had two years ago, and didn't delete any files from my ~library/application support/bitcoin or any other bitcoin related files... sooo... befuddled.

Any insights, anyone?
I guess you already looked there, but when I open a terminal and enter
ls -la ~/Library/Application\ Support/Bitcoin/ 
I see all the files there, including wallet.dat. Please note the backslash before the folder name space.
