On Mac OS Siera, having slow responses and constant "beach balls", trying to clean out unused apps, and, cpu and memory space hogs. Eliminated the actual Leapfrog app pieces, but cannot eliminate or uninstall LeapfrogMonitor.
MacBook Pro, macOS Sierra (10.12.3), beach balls after 15 minutes
No idea what Leapfrog is, but your Mac could have numerous reasons for slowness including a failing hard or too full hard drive or inadequate RAM. It sounds like you suspect a too-full hard drive.
One thing you might want to do is to download and run Etrecheck, which will give you a comprehensive view of what is going on with your computer. You can check the SMART Status of your drive and see if inadequate RAM is a factor among other things.
If you need help sorting out the report, you can post it here.
Good luck!
