so....did you recover them?
I COULD NOT RECOVER USING ANY OF THE METHODS PEOPLE SUGGESTED, I THANK GOD I HAD A PREVIOUS APPLE TIME MACHINE BACKUP WHICH WAS ESSENTIALLY A SNAPSHOT OF THE MAC FEW MONTHS AGO,
WHICH HELPED ME PUT MY ENTIRE MAC TO THAT TIME, INCLUDING THE ENTIRE ELECTRUM WALLET.
I'D BE WARY OF THESE UNLESS YOU CAN BACKUP VIA TIME MACHINE LIKE I DID.
THE MONEY EACH BTC HOLDS IS HUGE ,SO BETTER DO YOUR HOMEWORK TO PREVENT CRYING LATER...
JUST MY OPINION AFTER GOING THROUGH THIS SHIZ.
oh well 
Let this be a wake up call to you and all other crypto users.. Always make backups of your wallets.
I have lost a small amount of BTC (~0.05) by accidently deleting wallets and not having copies of them or the provate keys.
The nature of crypto dictates that you should always prepare for the worst and have multiple backups of your privkeys in safe locations.
Paper wallets in safes are a great idea, so is having a USB drive locked away with all of your private keys as well.
Practice security and common sense at all times to avoid things like this.
