(1) When the Ethereum Wallet is upgraded to 0.9.3 and then opened, it prompts to upgrade to a new version of Geth. Although it's on a Mac computer, the Geth version it suggests is type "amd/64", which is a type associated with Windows computers. Should the "amd/64" version be downloaded on a Mac, skip it or what other action should be done?
(2) What is the role of the Ethereum Wallet download versus the separate download of Geth (i.e. what does each application do)?
(3) Does the installation of the latest Ethereum Wallet also need the current version of Geth?
(4) Is the current version of Geth required for the Ethereum Wallet to fork to the Byzantium blockchain and continue downloading blocks past 4,370,000?
I am referring to the Ethereum Wallet releases found here: https://github.com/ethereum/mist/releases
