Mac OS X

After Lion anything's possible...

Lion OS 10.7 has been released and some reviews have called it the dawn of a new line of operating systems.  Apps are now a part of the user interface, influenced by the success of Apple's iOS mobile system for the iPad and the iPhone.  Microsoft's Windows 8, still in development, is said to be also including apps as part of their new operating system.  

Mac OS Lion has built into its new system substantially increased security defenses against the possibility of future exploits.  Not only is malware guaranteed to be confounded by this new operating system, some users are also finding it very difficult to interface with.  

With OS Lion, Apple changed some of the user's interaction with its system to the same motions used with an iPad.  Scrolling is now reversed.  Many of these new settings can be changed back to the old way you are used to interacting with your computer, however.

Lion appears to be having problems with many Adobe productivity programs as well as other numerous issues:

Before deciding to upgrade to the latest operating system for any computer, it is always wise to research and consider first, or at least wait for patches to be available to resolve the problems and bugs inherent in the initial release.

Java is not included with Lion and must be installed separately.

The Mac system is not vulnerable to the viruses and other maladies that target the Windows platform.   In this way, it is safe from most of the afflictions that can enter a computer.

Recently however, Macs have been targeted by hijacked websites that tried to convince the Mac user to install a program called Mac Defender.  The program is immediately downloaded into the computer and if the user runs the installer, the Mac becomes infected with this malware.

Apple has issued a security fix for this type of attack in a recent Apple system update.

  • It is good practice to allow all Apple system updates to install.

  • It's important to never install an program offered to you or downloaded into your computer based on scare tactics or promises of maintenance that can be found on unknown websites. If you are not sure of a program, do research about it before installing it.

Antivirus software is not needed on a Mac. Mac antivirus software, which use signature files (updated data files) are virtually worthless.  There is nothing in the wild to update to a data file for them to scan for.  Many of these programs are poorly engineered and can actually cause harm to the stability and performance of the computer.

The only virus encountered by Macs at this point in time, is the now rare MS Office macro virus.  Clam Antivirus is the most useful antivirus program to use in this case, and it is free of charge:

In 2006 Microsoft released a tool to help detect this virus in Macintosh systems.
