Finder freezes on right click

Hi,

I've installed El Capitan today using clover on my Intel i5 with ASUS B85M-G. Everything is working perfectly except when I right click on anything in Finder (i.e. a folder or a hard drive) the little beach ball/umbrella appears and I can't use anything in Finder until I reboot. Does anyone have an idea what might be happening here?

Thanks!
