Da sito Ledger “Prior to Starting
You need two things to ensure that your Ledger Blue works:
The connected computer must have a Chrome (or Chromium) browser running, which is needed to open your wallet and access your accounts.
Your Ledger Blue with the USB cable attached or Bluetooth running. This is needed to log into your Chrome applications and authenticate transactions”
“You can install and uninstall several applications such as Bitcoin, Ethereum, Ripple and many others (altcoins, authentication, etc.). Some of them are provided by Ledger and some by other companies.
By default, there are already some applications installed on the Ledger Blue:
Bitcoin
Ethereum
FIDO U2F
These applications can be removed or replaced. You can add new applications through the Ledger Manager, which acts as a free app store to download and delete your applications.”
Fra pochi giorni comunque dovrebbero uscire le app native Ledger
Ok grazie
