I just downloaded Sierra, and my MagicJack does not work. Is there and update for this ?
Thanks in advance,
Unfortunately, there is no update for the Mac Sierra. The program doesn't even appear on the Mac App Store. I've also checked their official website as well and it appears there is only the mobile application which you can download for Android or iOS.
I recommend contacting the developers, because the program might be available only for customers that are logged through the official website.
