I am using a MacBook Pro 2011 and I am having quite a few issues when accessing the web on it. I was advised to upgrade to the latest OS and I have done so. Took a while for any of my browsers to load up Twitter and Facebook. They finally do load now, although many of the images and profile icons do not display. I've also noticed that certain news websites and short links from twitter will not load. I keep getting an error message telling me that its not a private connection I'm actually not sure if you can see this image as I can't get flicker to display the images correctly after I upload. So there is an attached file on this thread too. Do you have any suggestions to how I could resolve this issue?
