Quick Summary
Error 52 on macOS generally indicates a problem with file system permissions or corrupted installation files during the installation process. This prevents the system from properly writing the necessary data, leading to installation failure.
Common Causes
- Insufficient Permissions: The user account attempting the installation lacks the necessary read/write permissions to the installation directory or related system files.
- Corrupted Installation Files: The downloaded application installer file is damaged or incomplete, rendering it impossible to extract and install the application correctly.
- Conflicting Software: Another application or background process is interfering with the installation process. This can include anti-virus software, system utilities, or other installers.
- Disk Errors: Errors on the hard drive can prevent the installer from writing the necessary files, causing the installation to fail.
