I recently found out they were getting bigger, so I tried to open bitcoin with my wallet, but it crashed, so I moved it from my mac to my PC.

By the sounds of it you either didn’t copy the wallet. Either way you certainly don’t have a workable wallet on your PC now, do you have another backup of your wallet. I have exactly the same problem. Install new client into your Mac from bitcoin. Do you have Time Machine backups?
