I loaded the 10.11.3 Capitan update yesterday (20th Jan) and since then my MacBook Retina cannot load webpages. It will occasionally load a page but it might take ten minutes for this to complete and then links on the pages appear to be dead. The MacBook (2 years old approx) is fully up to date regards all software and was working perfectly until this update. Anyone else having this issue? Any suggestions about what might be causing it? Or how to fix it? There is nothing wrong with my internet connection - I' m using my iPad to post this message.
