Hi Bronxteck,
I can confirm that all requirements are met. the DW1550 supports Bluetooth 4.0 LE. the OS believes Auto Unlock is supported it offers the Unlock this Mac with Apple watch option in privacy.. but when clicking on it it will not find the apple watch.. (it actually shows both mine and the wife's apple watches (as all apple devices are under my iCloud account) )
since there is a lack of information on the various hackintosh forums (some have got it working by using a wi-fi card from an actual mac) there is also a large amount of people who have been unable to get it working with genuine apple hardware, so may just be a gimicky thing that does not work 100% right even with genuine Macs. Sure would be nice though.
