Chrome not updating mac
(especially since as I said, I'm not good with computers, and I'd probably just screw everything up and lose all my stuff). Google Chrome on Windows and Mac auto-updates itself on a regular basis.
If you're doing web development, there's an option in the developer settings to disable the caching of assets entirely while the console is open to facilitate the rapid reload of new resources. I have this issue from time to time myself, especially when I am making lots of changes, I find clearing your browser cache works best, unless you have specifically set up some sort of caching.
When it's active, same story: I get my new server; when disabled, my old redirection comes along. Cheers from Berlin and thanks in advance In case some of you have the same problem: In my case I had to change my Mac's (all machines) DNS server, flush DNS cache and also flush Chromes DNS cache.
