I was a PC user, and I'm trying to get the hang of my new MacBook Pro. I've found AdBlock necessary for certain sites and browsing and decided to download it on my MacBook and for Safari. The first site I went to was http://safari-adblock.en.softonic.com/mac When I clicked download, it asked for my permission to install which I did. The file disappeared and nothing happened while the site itself just said "Please wait while this file is download..." which didn't happen... Is this normal? As I'm new, I couldn't find the file or any history of downloading and installing it. Afterwards I went to safariadblock.com and it worked great... Do I need to be concerned about the previous "download"? Thank you, and I apologize if this isn't a good question.
