Well this sucks. I just tried to access the online tool on the CRA website so I could update my address. Turns out they don’t “support” Safari: My Account – Notice to Macintosh Safari users. That’s sort of silly. The warning I got was that it’s an Apple problem and not a CRA problem. This sucks. I tried Firefox and (gasp) IE but both of those crashed when trying to access the site after it did some Java check.
