So. I have a problem. Suddenly Mail and Firefox can connect to the internet, but Safari, Google Chrome, App Store and iTunes can not connect to the internet. So I am online. But... What happend. I downloaded Replay Media Catcher. Tried it. Hated it. So I did the following.: Went to Finder Searched for Replay And deleted 3 files. The App, it's folder and woops... Some system file maybe? It was there under the search. After that. Safari and so on, didn't have an internet connection. So what file did I "accidently" delete? I already tried to reinstall Mac OS Sierra without deleting my files. Didn't work. Any suggestions?
