how can i unistall an application
how can i unistall a program form my macbook??
What kind of program? If you purchased the program from the Mac App Store, you can just click and hold down in Launch Pad, then click the X to delete: http://support.apple.com/kb/HT4673
Other applications can often be deleted just by putting them into the trash. However, there is no guarantee that will do the job. Some applications need more extensive uninstallers and not all of the provide that.
