Help Needed - DynaDock U El Capitan
 

Hello,

I have a Toshiba DynaDock U.

It was connected to an old mac running El Capitan and worked great. I didn't set it up, a friend did.

I had to reinstall the OS and now it won't see the second monitor.

I can't find any info to help. I tried reinstalling drivers (displaylink drivers) but it says it can't coz there's already a newer one installed.

Does anyone have any info on what I can do to get this up and running again?

Thanks.
