I just graduated from high school and got a new uMB last week that I will be taking to college this summer. I had a mac before but it was about 5 years old and running 10.4. All the new features are nice, but I have a few questions. A. In firefox, sometimes websites will only load in plain text without any formatting. Notable, this website and facebook. I know it has happened to more but I don't remember what. B. In iCal, there used to be a drawer-type thing that extended from the right side that would show you all the details. In this version, i can't find where to open that, and I have to double click on things to see the details. Did they get rid of this drawer? It was really helpful. C. In iChat, do both people have to have iChat to video chat or can the other person be using the google video chat? D. In the finder sidebar, it used to fave a link to movies, pictures, music, etc. Has this moved? E. Do I really need to upgrade my RAM or is the amount it came with sufficient for Firefox, iCal, iTunes, Word, and sometimes photoshop to run?
