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.

7.
Repair disk permissions with Disk Utility
a.
In OSX Yosemite and earlier,
Disk Utility
can repair file permissions on a startup disk. Permissions are file
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.
