I am having a problem "Finder isn't responding" on my mac pro retina 10.10.1. All my files on my desktop are gone and the rainbow ball is spinning forever. I've tried many times to relaunch "Finder" by using command + option + esc, yet the problem still exist. So anyone has any idea to fix this problem? Please kindly help.
Please upgrade your OS to OSX EI Capitan which is the latest version of Mac OS X and possibly fixed many bugs of Yosemite and works really fast has inbuilt memory optimizer tool to free up RAM.
