OSX Mojave - Black screen with cursor

vikas027 · 09-13-2018, 03:06 AM

Hello Guys,

I am facing an issue where my external displays are detected but the only black screen with mouse cursor is visible. The problem is exactly as mentioned here but for Windows.

These are my OS version and peripherals.

Laptop - MacBook Pro 13" 2018
Mac OS - Mojave 10.14 (18A389)
Display Link - 5.0 (13)
Targus dock with USB output
Apple USB to USB-C adapter

Interestingly, the same dock works perfectly when I connect my office colleagues' laptops.

MacBook Pro 15" 2014 on Sierra
MacBook Pro 13" and 15" 2017 on Mojave

Does anyone know any workarounds to this issue?

Cheers,
Vikas

If you have the workaround driver, it might be you need to grant permissions to the driver somewhere. There should be some detail on one of the threads.

It's the one currently on the display link site; think it just went to 4.3 but prior to that it was beta...5 i think.

You go to Settings, Security & Privacy, and where it reads 'Allow apps downloaded from:' make sure App Store and identified developers is selected.

After install there might be a display link item there for approval; if so, enable it and reboot.

Hey, I have already tried the same in vain

Now that Mojave is released, is DisplayLink going to release a driver that solves the black screen issue on 2018 MacBook Pros?

I work in a company as a IT support and we have a lot of Macs. The thing i noticed because i told my guys to use drivers 4.3 and not to update to newer versions of MAC OS is that when they did an update today to Mojave the old drivers worked like a charm. They were 4.3 drivers, and the new one are not working. Now the biggest problem is that i cannot install old 4.3 drivers on Mojave cause its not compatible. So right now im testing on MAC Pro 2018 to install 4.3 drivers on High Sierra and then to update to Mojave and see if that will work. That may be the workaround for now, and for the developers at Displaylink to maybe enable installation of 4.3 drivers on Mojave as well.

I have done some more tests and looks like there is something new in 2018 model laptops which have not been looked after in all DisplayLink versions of Mojave.

This is what I did -
- Created a bootable copy of my MacOS on an external hard disk
- Used the external hard disk (i.e. my MacOS) to boot my colleagues 2017 laptop
- Tried the USB dock and voila!! ...it worked as it should (have attached a screenshot hereby, her is a link too.)

Since my exact OS worked on my colleague's laptop, I can rule out any misconfiguration at my end. It has definitely something to do on the new 2018 laptops.

Am I the only one who gets a permission error when clicking the image in vikas027's post?

"brossow, you do not have permission to access this page. This could be due to one of several reasons:"
