Ages ago my boyfriend put a password on his Mac to stop his flatmate going on it, unfortunately that didn’t work because it’s different to Windows and it doesn’t stop you using it. But it does stop him from updating his iTunes and things, and he can’t remember his password at all.
When a computer user selects a password or for a website, application or wireless network to keep this information is the account to save the system on the hard drive. For Mac users can use this information secure password on the program “Keychain Access utility” to be taken into consideration.
