This adapter has a switch so you can use it on PC as well as console, which will turn it into an HID device rather than a proprietary console only one. You can get an official one, but the Mayflash adapter seems to work fine for half the price. Support may vary though depending on the adapter you get. You’ll need an adapter of course, but Windows and Mac should be supported by default through HID.

However, the current release doesn’t work either, so you’ll have to build the latest commit from source in Xcode, update a bunch of build targets, fix a few errors, sign it with an Apple developer account, and then after all that you have to boot into Recovery Mode and disable system integrity protection to install it. Only then can you properly connect the controller. MacOS Sierra broke support for the only driver, Wjoy, but it was updated on a new fork. System-wide use is technically supported, but we heavily recommend finding a new controller. Mac is supported in the same way-only in Dolphin.
