I downloaded the original bitcoin wallet for the mac in 2014. I purchased my first BTC around that date and I simply did not keep my wallet synched and up to date. I attempted to download the blockchain from bitcointalk.org and it did not work. However, after downloading, my wallet now says I have 0.0 BTC available and 0.0BTC pending. However, on the right side you can still see the transaction history from when I originally bought the BTC and it shows the full amount there. Is my BTC permanently gone? How can I retrieve my BTC and synch my wallet to the current blockchain? Any help would be great and I would even be willing to send some BTC as a reward to anyone who can help me retrieve my BTC.
