Hi @e4andy, welcome to the forum… No Target doesn’t run on Mac, it has to be Windows, I use Bootcamp on my Mac to run Windows 10, the latest version is of Target is (7.1.9) you will probably need Noahlink Wireless to connect to your aid’s to a Windows PC, so you can run the software, and ultimately program your aids… Noah is usually available on eBay for around 200 USD… I have Target, but I have no way of giving you a link, I assume, most of the DIY’ers get Target from a few kind souls on here, whom provide them with a link to their personal cloud based data, 'tis how I got mine, and I am extremely grateful for the service they provide hopefully someone will PM you… Good Luck, Cheers Kev
