While I knew this could be an issue, Howard’s work highlighted just how common it is to have a mix of executables bundled within apps. Go64 leverages Spotlight to compile a list of executables, but then does a deep dive into each 64-bit application to check for any helper apps, frameworks, services or plugins that might not be 64-bit. “It’ll only take a couple of days…” – famous last words uttered by nearly every software developer at some point in their careers.Īs they say, the devil’s in the details, and dealing with the vagaries of what goes on inside applications got interesting. I dusted off Go64 and figured I’d turn it into a more complete solution. He wrote his own exhaustive scanner that searches for them, but it’s slow and still not very user-friendly. Howard Oakley at the Eclectic Light Company had been doing some deep-digging and highlighted a number of issues with 32-bit app checking. Clair Software, plus dealing with the App Store always seems to ruin my day.įast forward to WWDC 2019, when Apple confirmed that Catalina definitely won’t run 32-bit apps. So I shelved it – there were higher priorities at St. That wasn’t something I could fix or work around. Then came the task of trying to get it approved: App Store Review rejected it because it asked for permission for the entire disk so it could scan for apps. Still, it was much easier to use, so I figured I’d release it in the Mac App Store. ![]() ![]() It took a fairly simplistic approach, and worked fine but was no more thorough than what System Information provides. ![]() Over a weekend last fall, I put together a straightforward little app to scan for 32-bit applications and show them in a list. The built-in System Information app does work, but it’s certainly not the most user-friendly, nor is it necessarily complete. After Mojave started warning about 32-bit apps needing to be updated, Ronald Leroux, who does all the French localizations of my software, pointed out that there wasn’t really a good way to check for and update 32-bit apps on your system.
