I have been messing around with the Raspberry Pi 3 and as a result I started looking through old devices I haven't used in years to see if I could repurpose them in some creative way with the Pi. One of those items was the original MagicJack. I am still working on the Pi solution using the MJ but in the meantime I will try to make it work on a new Macbook running Sierra.
This is one of the more visited articles on my blog and it never occurred to me that the people reading the directions wouldn't be technical. The terminal is a bit confusing to others. I had a Macbook Air that I hadn't installed the update on and so I decided to run the setup there, and then record it. The video is embedded below.
Plugging the device in for the first time in 7 years I was surprised to see it launch. When I attempted to run the MJ software though I got a message after the app quits, Magicjack quit unexpectedly. OK, no biggie, time to go and find the updated software. I found this post on Facebook and from there I was able to download the most updated software. Here is the link for it. http://upgrades.magicjack.com/mjupdate.dmg
The magicJackSetup application in the DMG file you download will not run and you'll get a message saying "magicjack setup is damaged and can't be opened". It's not. Don't give up quite yet.
Open a terminal and run the following
sudo spctl --master-disable
If you run the magicJackSetup app again now it will run and install on your Mac. Your MagicJack should now run as well.
You will need to turn on security again for downloaded apps.
sudo spctl --master-enable
