Apple’s upcoming OS X 10.11.4 update will fix broken Twitter links in Safari. The fix is already available in the third 10.11.4 beta, which rolled out earlier this week, and it should be available to all by the end of March.
Since back in October, Safari users have been plagued by a bug that prevents shortened “t.co” links from loading when they use the secured HTTPS protocol. In most cases, Safari simply displays a blank page for a few minutes, then throws up an error.
The browser claims that “the server where this page is located isn’t responding,” but in actual fact, there’s nothing wrong with the server at all; it’s all Safari’s fault. Fortunately, Apple has fixed this issue in 10.11.4, according to developer Dieter Komendera.
Apple is expected to make 10.11.4 available to the public in early March, but in the meantime, you should be able to load “t.co” links by removing “https” from the beginning of the URL. Alternatively, you can just paste the link into another browser and open it there.
