11 easy tips to secure your Mac against hackers

Today, it is still true that Mac has fewer malware problems than its counterparts Windows and Android. But, it does not mean that Mac is immune to hackers, or that Mac users should take its security lightly. In 2013 Reuters reported that some Mac operating systems of Apple employees were infected with malware. So, case in point here is that your Mac operating systems are in dire need of security than you think.
