Hey all, so I just got my first macbook yesterday, and today i download serval apps. I attempted audible but couldn't because I didn't have a palm hardware? I also download Capti Narrator to access bookshare books, I just wanted to make sure that both of these are safe, didn't bring any virus from the internet over on the download. In addition, do I nerd any antivirus software like notron on my mac. For the audible and Capti narrator download i did have to say allow downloads from anyone and just not apple aproved.
