Where are Swarm settings on Mac?

With the latest 4.10.2 the system HD on my Mac is getting bloated with 10 gigs and more because of Swarm folders. That’s way too much for my flash system drive to handle. They’re in the depths of the Application Support subfolders. Mac doesn’t seem to have a Swarm Agent to modify any settings. This wasn’t a problem before, so something seems to have changed. Any options to change the cache location or limit their size?

Also, possibly not related to this, UE Editor has started to use about a couple of gigs of RAM extra while in the background, ie. not really in (my) use. The memory is freed when I switch back to the Editor. That, being used to Macs being capable of running several even more intensive programs at the same time easily without hiccups, is a serious workflow problem as the whole system starts to stutter with usually only a few megabytes of memory left free. And this is with very light use, nothing CPU intensive or other going on. I’m using Mavericks 10.9.5.

I’d appreciate any help!

So, what I gathered, there is no Swarm Agent on Mac. Any possibilities to change the cache location? System drive shouldn’t be the default place for it.
