Detect and view information about the applications installed on your Mac, as well as code bundles and command tools based on the 32-bit file structure. Gain access to the full set of system data and customize the presentation by changing text size, switching screens, etc.
Download of 32-bitCheck 1.8 for Mac was on the developer's website when we last checked. We cannot confirm if there is a free download of this app available. We recommend checking the downloaded files with any free antivirus. This free software for Mac OS X was originally created by Eclecticlight. The program lies within System Tools, more precisely System Optimization.
From the developer:
32-bitCheck is a much better tool for checking which apps and other software are still 32-bit. Check the folders of your choosing, and can check just apps, or all bundles including plugins and other executable code. Generates text reports to help you prepare your Mac for macOS 10.14 later this year. Why waste time and effort using System Information?
You may want to check out more Mac applications, such as WinShortcutter, Vicomsoft FTP Client or Mac Pilot, which might be similar to 32-bitCheck.
