Fix rpcsvchost Process Using Excess RAM & CPU on MacOS

A somewhat rare reason that MacOS can feel excessively slow is due to a runaway process in the background, in this particular case; rpcsvchost. You might find this in Activity Monitor or another resource monitor, consuming an unusually large amount of RAM and/or CPU, in which case you’re probably wondering what this process is, and whether it’s safe to kill it.
If you were wondering, yes, rpcsvchost is a legitimate system process for MacOS, but it can still occasionally misbehave and contribute to unusually high CPU usage or excessive memory consumption (enough to swap and use virtual memory), both of which can make a Mac feel notably slower.
Let’s dive a bit into what rpcsvchost does, why it might be using excessive system resources, and how to troubleshoot the problem.
