Quick Summary
Error code 0xE in macOS typically indicates a general installation failure. This often means that the system encountered a generic issue during the installation or update process that prevented it from completing successfully.
Common Causes
- Incomplete Download or Corrupted Installer: The installer file may have been incompletely downloaded or become corrupted during the download process, leading to missing or invalid data.
- Insufficient Disk Space: There might not be enough free space on the target drive to complete the installation. The installation process requires space for temporary files in addition to the final installed application.
- File Permissions Issues: The user account might not have the necessary permissions to write to the installation directory or modify system files, causing the installation to fail.
- Conflicting Software or System Components: Existing software or system components may be interfering with the installation process. This could include security software, background processes, or incompatible system extensions.
Step-by-Step Fixes
Method 1: Redownload the Installer
Step 1: Delete the existing installer file.
Step 2: Go to the official source (usually the developer's website or the Mac App Store) to download the installer package again. Ensure you have a stable internet connection during the entire download process.
Step 3: After downloading, verify the file size or checksum (if available) to ensure it matches the expected value.
Method 2: Check Disk Space
Step 1: Open Finder and click on Applications in the sidebar.
Step 2: Press Command + I (Get Info) on your hard drive (usually named 'Macintosh HD') to view the available storage space.
Step 3: Ensure you have sufficient free space (at least double the size of the application you're trying to install) for the installation to proceed. If not, delete unnecessary files or move them to an external drive.
Method 3: Repair Disk Permissions
Step 1: Open Disk Utility (found in /Applications/Utilities/).
Step 2: Select your startup disk (usually “Macintosh HD”) in the sidebar.
Step 3: Click the First Aid tab.
Step 4: Click Run to start repairing disk permissions. Allow the process to complete.
Method 4: Disable Antivirus/Firewall Temporarily
Step 1: Temporarily disable your antivirus or firewall software. Consult the software's documentation for instructions on how to disable it.
Step 2: Try installing the application again after disabling the security software.
Step 3: Remember to re-enable your security software after the installation, regardless of success.
