[Mac] Ledger connection stuck on app restart

[tuliomir]

On the Mac version, under specific conditions, the app is unable to identify that the Ledger is ready to be used and leaves the user stuck on a waiting screen.

Steps to reproduce:

• Open a hardware wallet successfully
• After the all the transactions are loaded, close the app using the "X" icon of the operating system. ( Do not use Cmd+Q )
• Open the app again and select "Hardware Wallet"
• The app should be stuck waiting for the app on Ledger, even if the ledger is on the correct state

To solve this issue, just close the app using Cmd+Q and open it again. The ledger will then be correctly identified and the user will be able to log in again.

The expected behavior would be for the app to identify the ledger without having to use the "Quit" option from MacOS.
