There is a way to hack a mac pro even if you have a password. How do I prevent hacking?
My friend can actually hack a mac pro just by restarting it even if you have a password to protect your mac. My mac is curently mavericks.
Steps: 1.When you open a mac with a password in mavericks, click switch user.
2. After the page loads, click restart.
3. After the computer shuts down and is turning on again, press command s.
4. My friend just typed some code and managed to change my password.
He told me the password and i changed it back, but i wanted to know how to prevent this hack from happening again on my Mac pro.
