Scanning your system for 32-bit apps.

Overview

Go64 helps you prepare for macOS 10.15 Catalina by scanning your system for 32-bit apps. Those apps won't run in Catalina, so it's best to find them now.

Note: While the software is classified as free, it is actually donationware. Please consider making a donation to help support development.

What's new in Go64

Version 1.1:
  • Added the ability to hide applications in the list if you've decided they don't matter to you.
  • Fixed a bug that caused the count of 32- and 64-bit apps to be incorrect when running in French.

Two similar apps -- neither of which are found on MacUpdate -- are 32bitCheck by The Eclectic Light Company, and RoaringApps by Bryce Cameron. Both of these do more than just looking at macOS's System Information panel.

This was really useful for hunting down my old 32 bit apps (mostly Adobe!).

Makes me sad. Some of those 32-bit apps are awesome. I do love that you can click to go to each company's website, can show in finder (of course), and that it found things in the System Application Support folder. The Last Used column is helpful. I guess I shouldn't be too sad because I haven't run many in a few years. I like this too - shows a yield sign for - "It may or may not run correctly on macOS 10.15, depending on how the app handles situations where its 32-bit components would normally be used. Check for a more recent version or contact the application's developer for more information." This company has been around forever. I trust them. I do recommend adding an app that cleans out all the related software (just be careful) when you delete the app (you can in the app).

Why use two apps when one does the job? Furthermore, Go64 interface’s is great and getting better with each update.

BTW, The Eclectic Light Company also has another app called ArchiChect which is a drag and drop app which allows you to check individual apps, bundles, etc., to see if they are 64-bit or 32-bit. He has a lot of other very useful apps as well.

Roaring apps sends a list of your apps to their server. No thanks.

Please contact me at support@stclairsoft.com. I think I know what the issue is, but would like to have you run a test build to confirm.

I've found the problem and fixed it in version 1.0.3, now available from the St. Clair Software website (and from MacUpdate's download link).

This app may conveniently find 32-bit apps for you; however, macOS has built-in support for IDing 32-bit apps: Pick 'About This Mac' from the Apple menu, then click the 'System Report…' button in the resulting pane, then double-click Applications under Software. It generates a list of all installed apps (not just under /Applications and /Applications/Utilities) with a column titled '64-bit (Int…'. Click on that column header to sort by 64- vs. 32-bit.

BUT—This nice app does more. For example, an app's main executable file might be 64-bit but Go64 looks inside the app bundle and might find 32-bit code there. For example, on my system it discovered that DEVONthnk Pro office is 64-bit but inside its bundle is a 32-bit app called OCRPlugin.bundle.
