I had the exact same issue with my 10.6 os. I upgraded to Yosemite 10.10 and it works fine + syncs in about 20 hours instead of 3 days it used on my old os. the issue i have now is that in my AppSupport folder i can't find anywhere the Bitcoin folder to import my wallet.dat file.
You don't have anything in ~/Library/Application Support/Bitcoin folder?

I've been using my old MacBook as a full node for a couple years without a hitch. Just upgraded Bitcoin-Qt to 0.10.0 and now it crashes upon startup. Any thoughts?
