Hi, Im a total newbie, I know some basics but that is it. I just purchased an early 2011 macbook and it came with Mavericks. So, I want to install a program and i have NO IDEA HOW TO DO IT! Macs aren't like windows at all! So, my co worker had this Avid program (we both work with avid but I used to it on pc and he on mac, we paid the license together) and we want to install it on my new mac, I copied the program on to a cd and don't know how to run installation on this mac. Same with Premiere. I tried to Install today a Canon Software (from Canon´s cd) and a white window comes up and it says: Last login: Thu Dec 5 01:33:10 on ttys001 MacBook-Pro-de-Angitop:UIxEUInstaller.bundle MAC$ what is that?!!! It came up with another software I tried to install. How do Macs work? i tried watching youtube videos but none talk about this basics....help!!!! thanks!
