We recently reported that Apple is now beginning to warn users about 32-bit applications potentially not working in a future version of macOS. The alert that appears on macOS is surprisingly vague and doesn’t give much detail on what to do next.
Apple just released Safari 5.1.5 on its website and through Software Update, and it only contains a fix for a bug “that could affect website usability” when in 32-bit mode. The update follows a larger release earlier this month with Safari 5.1.4, which included a long list of Javascript, PDF, and HTML5 related security and performance improvements. In February, Apple rolled out Safari 5.2 for Lion to developers as part of the Mountain Lion preview. That release will likely be available to the public alongside Mountain Lion this summer.
