Lost Wallet - Newbie cleared web history on MAC

Ok so Im new - no excuse for stupidity! I have cleared the history on my browser now the nano wallet shows no wallets,
main issue is that I cant find the wallet backup file on my mac to “import wallet”. 70000nem gone? Your help in resolving will be much appreciated. thanks in advance.

I don’t have a mac but this doesn’t look good.
You should search again for the backup file.

If your browser is Safari, the backed up file name is “Unknown”.
In that case, please attach the extension “. wlt” to the file name “Unknown”.
Wallet will be repaired by you loading “Unknown.wlt” from NanoWallet.
