M|Connect appear in System Information.
a. Unplug the USB cable from the computer then power cycle the M|Connect.
b. Reboot the computer.
c. If this does not make the M|Connect appear then skip to step 7.
6. If the M|Connect does appear but still does not work, check the Product ID (PID) should be checked to make sure the
device has started up correctly.
a. Click on M|Connect in the System Information to select it.
b. The product ID should be shown in the device properties. It will be a value like 0xXXXX, where XXXX can be any
hexadecimcal value (0-9 or a-f).
c. If the PID is 8060 or 8080, then the device has not booted up correctly. To recover the device:

7. Repair disk permissions with Disk Utility
In OSX Yosemite and earlier, Disk Utility can repair file permissions on a startup disk. Permissions are file
a.
settings that affect the ability to read, write, or execute (open or run) the file. If a file's permissions are no
longer set correctly, software that uses the file might not work correctly. Permissions can be seen in the
Sharing & Permissions section of its Get Info window. Important Note: Beginning with OSX El Capitan
(10.11.x), system file permissions are automatically protected. It is no longer necessary to verify or repair
permissions with Disk Utility.
