Configuring Mac Computer Online Privacy Options
The first thing you should check when setting up your Mac online privacy options is the firewall. This can be found in System Preferences > Security > Firewall, and its activation is vital to safe and private online activities.
You can switch the Mac firewall on by clicking Start. You may have to click the lock in the lower left-hand corner of the window first to unlock the option.
Further security settings can be found in your browser, which naturally by default in OS X is Safari.
You can view and alter these settings via the Safari > Preferences > Security screen, where you can instruct Safari to advise you when a fraudulent website is visited, as well as specify how website cookies should be used.
Note that you can also use Private Browsing, activated from the Safari menu, to prevent a record of your recent browsing history from being viewed. This is ideal if you have concerns over who is aware of what websites you are visiting, but note that it is of no use in a corporate environment, where web servers are employed that record visits to websites.
When used in conjunction with passwords and your Mac OS X firewall, these Safari browser privacy tools can be used to great effect to protect your data from intrusion and maintain your privacy.
