I bought this adapter for my MacBook. For macOS you need to download the driver but the link printed in the instructions has expired. I contacted the company and got a new address for the driver. Installation wasn't easy due to lack of instructions and I almost gave up but was finally able to get it working. It works fine, but it is not known whether or not the driver will be supported in future versions of macOS. I haven't tested the range extensively, but so far it's working well. Product and customer service - 5 stars but installation - 3 stars.
