Greetings! I am the owner of a 2007 White macbook 3,1 and have some basic questions. I am currently running OS X 10.6.8 and having issues with my Universities Wireless config. The techs there said OSX lion was needed to help implement the config files. SO what i want to know is will i loose performance with Lion? i hear its laggy especially on my system due to my low video card. I already know about ML post factor. I already have the ML app. Just have no idea which update it is. So If i where to install ML using post factor is it reliable enough for a student to use? What are the current glitches. And how to find out what version exactly the installer is so i can correctly install it using ML post factor? I have a new battery in this Unit, 4GB ram and a 240gb SSD. SHould be more then efficient enough. But will lion of even ML give me the most of my battery and performance? Let me know as i dont have time in class to screw around personally trying to find the best config. So what are your experiences?!
