One of the few glitches I've found with my dearly beloved MacBook laptop is how the Apple web browser, Safari, fails to load all of a page much of the time.
Sometimes it stalls and I have to reload the page to get any content. Sometimes it will download some images, but not others -- leaving Google News or Google Reader, for example, littered with annoying missing picture icons.
As the suggestion on that link said, I went to my Mac's system preferences (under the Apple icon) and clicked on Network, then Advanced, and finally DNS. I added two lines under the DNS server info already there: 22.214.171.124 and 126.96.36.199
I have no idea what this does.
But it sure seems to have solved the problem of pictures not loading. Web sites appear to load faster and more smoothly now, so I wanted to share this tip in case somebody else has been frustrated with a similar Safari irritation.
