"Best OS in its time"

5/5

What do you like best about Apple OS X Mountain Lion?

I loved the UI graphics the most. It is a shame that Apple has faded out that look and feel. The system was well built, stable, virus free, powerful and easy to use. Review collected by and hosted on G2.com.

What do you dislike about Apple OS X Mountain Lion?

There was not much to dislike on Mountain Lion. It was very complete for the Apple eco system at the time. As they continued on sunetting backwards compatibility, I kept yearning for the nostalgic 90s. Review collected by and hosted on G2.com.
