Targus Posts v.5.1.1 for Mojave 10.14
Targus has posted the latest release 5.1.1 for all DisplayLink-based Targus Universal Docking Stations connecting to MacBooks with macOS Mojave (version 10.14.5) installed. The software and release notes are available from https://us.targus.com/pages/driver-support i.e. For the DOCK190, here.
Due to new driver notarization requirements in 10.14.5 Beta 2, DisplayLink driver was not available in security & privacy settings to be allowed.
Software package notarized by Apple as required for macOS 10.14.5 onwards.
A change in DL-69xx firmware distributed with DisplayLink software released after November 15, 2018 will prevent previous DisplayLink macOS software releases from operating with this firmware version. Therefore, it is recommended that all MacBooks in a hoteling or hot desking environment be updated to this version so that different MacBooks can be used on the same dock.
Any DL-69xx product which has been connected to a client device running DisplayLink software released after November 15, 2018, and then connected to macOS will require DisplayLink macOS driver version 5.1.1 or newer for correct operation. This includes Targus Universal Docking Stations models DOCK1XX and DOCK5XX.
