Leopard, the latest Mac Operating system offered by Apple, has more than 300 new features and is the most impressive operating system released by the company to date. Individuals and reviewers have expressed the opinion that Leopard is certainly worth the computer upgrade for most Mac owners. The system requirements include a Mac computer with a capable processor, 512MB and a DVD drive, which is utilized in order to install the operating system on to the computer. Volume licensing is available. While the drawbacks range from cumbersome stacks when there are more than twelve items in the folder, and that users are not able to drill down to folders in folders, the positives about the product seem to far outweigh these negatives. Leopard offers Time Machine, Boot Camp, Quick Look and improved text-to-speech capabilities. Time machine backs up all of the users' computer files, including music, images and software. This is done automatically. Boot Camp used to be strictly available as a separate download from the Apple website, but it is now offered from Leopard and allows users to boot their Macs into Windows. There is a dictionary panel and Safari web clips that are expected to help improve classroom learning with the use of snippets from any Internet page. The improved text-to-speech features allow writers to identify repeated words, passive voice and problems with punctuation, allowing easier corrections of papers and documents.
