Humanscale: M/Connect Troubleshooting Guide 10
5. If the device continues to appear with the same PID then then you should replace the M/Connect dock.
viii. If M/Connect does not appear in the system report:
1. Disconnect the M/Connect dock from the laptop.
2. Uninstall the DisplayLink software.
3. Repair the permissions (see below).
4. Once the permissions are repaired, reinstall the DisplayLink drivers.
5. If the drivers do not install, you should replace the M/Connect dock.
ix. If M/Connect does not work, you may have to Repair disk permissions with Disk Utility
1. In OSX Yosemite and earlier, Disk Utility can repair file permissions on a startup disk.
2. 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. You can see a file’s
permissions in the Sharing & Permissions section of its Get Info window.
3. Important Note: Beginning with OSX El Capitan (10.11.x), system file permissions are automatically protected.
It’s no longer necessary to verify or repair permissions with Disk Utility.
4. Follow these steps in OSX Yosemite (10.10.x) or earlier:
a. Open Disk Utility, which is in the Utilities folder of your Applications folder.
b. Select the startup disk from the list of volumes.
c. Click the First Aid tab.
d. To check permissions, click Verify Disk Permissions. To repair permissions, click Repair Disk Permissions.
5. Disk Utility checks a file’s permissions only if the file has a corresponding receipt in /var/db/receipts. The
receipt tells Disk Utility what the permissions should be. Not all installers include a receipt with the files they
install (to check a system folder, open finder and select “Go” from the menu and enter the directory that
you wish to show such as /var/db/receipts).
