It is. I found excel to work without a problem bur Word was a disaster when I started building a document with pictures, text, and text boxes. It just aborted, lost all my changes, and would not allow me to save under the same document name. Outlook crashed 2-4 times daily and had a problem with my gmail account. All updates were in from MS and OSX. I have up and went back to pages and numbers and Mac mail. I really did not use excel to the complexity that I did Word. Did not use PowerPoint. Hope this helps
That is OS my wife has and installed correct. I think I am gonna update the review, you are the second one asking me about the OS. I really didn't mean to be technical in the review but I think the OS version would help others.
