Hello Im new to this forum because I just got my Mac powerbook G4 and Im kinda Lost =/ I also have a VAIO with Windows xP and I been using it for years so I know everything about it and now that i have this Mac laptop I feel weird using it because im not use to it and dont know how to find anything but the thing that im most confused in is when I downloaded an .exe file for the first time It told me that it was unable to open it and that I need to choose an application to open it with So it took me to the application folder and i clicked on utility and choosed Installer and a pop up said INSTALLER UNABLE TO OPEN FILE. at that time I didtnt know that Mac cant open .exe files. my question is if i donwload a file that mac can open will the installer be able to open for example American's army game i read that it works for Mac I also dont know where to change background since i dont have RIGHT CLICK in windows xP you just right click and click on Options. I have to play around with it more till i get used to it xD I still think Mac is the best just hard to get used to it. Do any of you know a guide that tells you how to do simple stuff on a Mac Powerbook 4? Thanks.
