I’ve just gotten a report from one user that auto-update doesn’t work reliably for him. I’ve never heard of any other reports of this, so I am wondering if anyone else is having this sort of problem. Panorama X uses an auto-update framework called Sparkle to do automatic updates, which is used by hundreds (maybe even thousands) of Mac applications. I’m not sure what I can do if there are problems, other than ripping out Sparkle and writing my own auto-update code (there are literally only a couple of lines of my own code involved, so any problem would have to be in Sparkle itself). I’d be very reluctant to do that, since the code is quite complicated and Sparkle has been very widely tested as one of the most widely used third-party frameworks on the Mac for nearly ten years. But I’d like to know if this is a widespread problem I need to worry about.
