A:Answer The primary difference will be that most viruses are created for PC computers. Secondly, the PC operating systems are taking on more MAC features, however, MACs are best for graphic applications, and PCs are business computers. The MAC can be used in dual purposes, it has the ability to read/use PC applications, as well as MAC applications. It too is very user-friendly, and rarely crash. I purchased a MacBook in 2008, heavily used till 2017, it crashed once, and that was in 2016.
