Displays not working after 10.14 update.

[ukarea]

I have 2 Asus USB displays which both stopped after Mac OS 10.14 updated to 10.14.6. I have tried the information on https://support.displaylink.com/know...ticles/1188004 with no luck. Please is anyone able to help? I have included the output from the DisplayLink Information app.

Thank you.

Hello,

Thank you for reaching out!

Your DisplayLink device is no recognized under USB bus or was not connected when you gathered the logfiles.
If it was not connected please connect it and gather the logfiles one more time.

If it was connected please follow the link below to check if it is a hardware issue:

Thank you for your fast reply. I have redone the information as I think the cable was not in right.

I thankful for any help you can give as I have 2 of these monitors one of which is only a few weeks old.

Hi,

I have followed that but it still does not work.

Hello,

Were you able to successfully go through the steps that I suggested earlier?
If yes, could you send another set of logfiles that will show any other possible issues?

Thank you,

No. It does not appear in Security & Privacy at all. I also do not get a popup when installing saying blocked or anything else even after a clean driver install.

Hello,

Post installation you will not receive any notification that the kext has been blocked.
If you see in System Report->Extensions the section where is says Loaded and it says No there that means that the driver is blocked.

You have to make sure that right after you install it you go to Security & Privacy and you enable it it as this option is available only for 30 minutes post the installation. After that it will not show that option at all.

Can you please double check if after reinstalling it shows?

Thank you,
Katarzyna

It shows on the list as already allowed without doing anything after I install.
