I have an electrum BTC and LTC wallet as well as the NEM Nano wallet, BitShares2-light, Dash Core, and myetherwallet on my computer. An app is requiring the latest OS be installed so I thought I'd ask here before doing it... anything to be afraid of? Or just go for it? Currently running OSX 10.10.5 going to whatever is the latest
i made several OXS updates and had no problem with my wallets. make a backup and install the update / upgrade.
