I just bought a mac yesterday and I am new to them. I will do some tutorials later on. I downloaded mac:messenger for it because I thought that It would be the most compatible with mac. The program works fine and I have the icon on my doc, but along with it, it also installed a little icon (not the messenger one) just below the mac HD icon. I opened it and it opened a little window saying something like 80MB remaining. Is this the shared folder for messenger? I also initially wanted to get msn messenger 7.5 for my mac. If I were to donload it for mac would it be compatible? How do I uninstall programs?
