Software protection
You can protect the software programs that make your computer operate.
The General Controls control panel lets you lock your System Folder and

removed or renamed. You can still add items to these folders.
To protect the items in your System Folder and Applications folder, open the
Apple (K) menu and choose Control Panels. Then choose General Controls.
