About:
Go64 is a utility that scans your Mac's disk to identify all 32-bit applications installed on the system. As macOS evolves, 32-bit apps will cease to function, and Go64 helps you proactively find these incompatible programs before an OS upgrade breaks them. It provides a clear, sortable list of apps with version details, allowing you to plan for necessary updates or replacements.

Key Features:

Comprehensive disk scanning to locate all applications and their architectures
Detailed version information, including last modified date and 32-bit/64-bit status
Clean, native macOS interface for easy sorting and filtering of results
Quickly reveals apps that will be incompatible with future macOS versions

Use Cases:

Preparing your Mac for a major macOS upgrade by identifying incompatible software
System administrators auditing a fleet of machines for outdated applications
Developers checking their own applications for 64-bit compliance

Alternatives:

System Information (built-in) – Go64 provides a more focused and user-friendly interface specifically for finding 32-bit apps compared to the general-purpose System Information app.
Compatibility Scanner – A similar tool, but Go64 is often cited for its speed and clear, sortable list view.
