This is the new HTML5 wallet for I/O Coin with support for OSX Sierra. This is the beta version we are still testing it for any issues. Once your done downloading the wallet please be sure to download the entire blockchain file for faster sync our you can also let the wallet sync on it's own. At first it will be a bit slow to find the seeds if you want to speed that up you may add the file peers.dat below.
I/O Coin folder is located here ~/Library/Application Support/IOCoin
Make sure to always backup your .dat file prior to making any changes or upgrading. Copy and paste your entire iocoin folder if your doing an upgrade. Don't send to the wallet unless you have fully synced the wallet. Send 1 ioc or less as a test to verify functionality.
Thanks
