How to Permanently Remove Programs From a Macbook

Locate the program you want to remove from your MacBook in your 'Applications' folder. To access your 'Applications' folder, click the Finder icon in your Dock to open a new Finder window, then click the 'Applications' folder shortcut link in the left column of the Finder window.
Drag the application icon and drop it in your Trash. Unless the program specifically came with uninstall software, moving it to the Trash is the primary method of removing it from your MacBook.
Select 'Finder' from the top menu bar of your MacBook's desktop, then select 'Secure Empty Trash.' This action permanently wipes your Trash, which means you will not be able to recover your files, even with recovery software. You can also empty your Trash to remove a program from your MacBook; it won't be visibly present, but you might be able to recover it.
Click 'OK' when prompted by your MacBook to securely empty your Trash and permanently remove the program from your MacBook. The 'Secure Empty Trash' function will take significantly more time than just emptying your Trash. Depending on the contents of your Trash, the process could take 30 minutes or more. Do not attempt to open or move items to your Trash until the 'Secure Empty Trash' function has finished.
