“Apple may not have revealed its timetable for the removal of support for 32-bit software, but it has made it clear that it will happen, just as it did in iOS,” Howard Hoakley writes for Eclectic Light Company. “Mojave contains several tools to help us prepare.”

“New for Mojave is a section in System Information titled Legacy Software, which Apple claims details ‘all applications that have not been updated to use 64-bit processes,'” Hoakley writes. “I have no idea what criteria this uses for identifying apps, but it only ever reports a fraction of those which are known to be thoroughly 32-bit. For example, on this iMac with 335 known apps which are 32-bit only, it reports just 5: three support tools from Adobe, Apple’s Compressor, and a helper app for an old copy of QuarkXPress. It doesn’t notice that the whole of Adobe CS6 or Microsoft Office 2011 are also 32-bit apps, for example. Whatever this new Legacy Software item might think it’s doing, don’t even bother to look. It doesn’t make any sense, and will only mislead you into being complacent.”

“The situation with apps is fairly clear. Most of those left now have already been upgraded (Microsoft Office), or replaced by other apps (Adobe CS),” Hoakley writes. “Of much greater scale and concern are those code items which are not apps, but frameworks, plugins, and so on… Unless you have started with a ‘clean’ Mac in the last few years, it looks likely that a future 64-bit only release of macOS will still catch a great deal of software unawares.”

MacDailyNews Take: Hopefully, if you’ve got any older 32-bit apps upon which you depend, there’s already a 64-bit version available or in development. As for the rest of the 32-bit stuff – frameworks, plugins, etc. – unfortunately that might take a bit longer to modernize.
