This can be very frustrating when downloading large files.įor that reason, the benefits of the new multi-process architecture are somewhat dubious, at least until Apple manages to address the issue of spontaneously reloading tabs (assuming it’s even possible to prevent this behavior without redesigning the overall architecture of WebKit again).īasically, it’s a well intentioned feature, but it’s also causing some user headaches. ![]() Furthermore, any downloads that were in progress will also be halted you might be able to resume some downloads, but many will have to be started over. All web content is handled by a single web process, so if any page malfunctions and causes the web process to crash, all open tabs will be reloaded, and anything you had typed into any of those pages will be lost.

If you’re wondering why changing some setting called “multi-process windows” effects automatic reloading of web pages, Stormcloud provides a good description of what this feature is and how it works: Open a new Safari window and if you see an next to the web pages title, you’re now in single process mode, which prevents the automatic refreshing of webpages.The Safari App cannot be completely moved to trash - it says it is part of the OS. I have a choice of downloading a version that says it requires 10.6 to be installed, OR I can go all the way to a complete Mavericks upgrade.
