console help needed interpreting these messages on system.log

The message below keeps appearing in system log. I don't know if it means that there's a bug in my system or what. I was able to pin down the file for VTDecoderXPCService but I don't know if I should delete it or not. Does anyone know what this line of code means?

Logs are quite bad at this particular why-is-this-Mac-slow usage.


Download and enable full device access for and run EtreCheck, use the sharing option to copy the report, then open a new reply here and then press the button that looks like a printed page to open a text input box big enough to paste here, amd paste the hardware and software configuration report here.



With the EtreCheck data, we can know more about the hardware and software in use, and what might be causing this Mac to be slow.


If you do not have a current and complete backup, go get a backup now. This on the possibility that there’s a hardware problem arising here.
