Old Armory Bitcoin Wallet (help needed)

I recently found 2 single sheet armory wallets (paper backup for armory wallets) with QR codes and root keys and even have my old computer that I used to play around with these wallets with and the armory software still on there (version 93.1). Problem is I can't get this wallet to connect to the internet. It's always in 'offline' mode and doesn't allow to check balances / send / receive.

The Mac it's on is macOS Mojave 10.14.3

Tried downloading newer version of Armory on a newer Mac and it won't open at all.

Any help / advice would be greatly appreciated!
