DisplayLink Software - High CPU on MBA

theraque · 01-11-2019, 12:29 AM

I'm running Sierra 10.12.6 with DisplayLink driver 4.3.1 from 10 Oct 2018. I found that the DisplayLinkManager causes extremely high CPU% utilization. Killing the process has no effect as it auto-launches and continues to consume CPU.

I found that the workaround for this is to disconnect the dock (Dell D6000) then use Activity Monitor to kill the DisplayLinkManager and DisplayLinkUserAgent process and wait for them to respawn.

After this, reconnect the dock and it'll work as normal without high CPU usage.
