I have a Meridian Explorer 2 (E2) that won't work on Tidal with MQA on my 2015 MBP, which means the blue light won't display on it. However, When I use the DAC on my old 2012 MBP or my wife's MacBook, the E2 works just fine - the way it should. Both of these computers have an earlier version of High Sierra or, with the MacBook, just Sierra. I must conclude that 10.13.4 is causing a problem for the DAC. I don't know how to easily remedy that, or to contact Apple about the problem. Of course, it can also be a Meridian issue. Waiting to hear from them in the UK. Any advice would help. Thanks.
