New to Mac and have two questions... 1: I can't seem to find a way to disable folders from auto-arranging themselves. I want to organize some of my folders randomly but I can only seem to arrange them by Name, Date, Label, etc. Some direction would be helpful, as I haven't used anything but Windows until now. 2: In Windows I had System Clean-Up and System Defrag to help maintain and keep my system organized/clean. Does OS X have similar programs or is there any other type of program Mac has for users maintain their system? The help is much appreciated!
