The weird thing is that not a single variation of my passwords are working. Can't imagine making it anything else.
If you don't remember installing it, and never actually used it for any funds, then you more than likely just set up a wallet as a test to play around with for a few minutes before uninstalling again. Is it possible you used a generic password like "test", "123", "admin", or something similar?
Why not just navigate to the wallet file and look at its date of creation? That could potentially give you an answer. Open Finder and navigate to ~/.electrum/wallets. Your wallet files should be in there. Find the one called default_wallet and see if it was created recently or back in 2014.
