Symptoms
- The same app quits unexpectedly or shows a crash report
- Other apps run normally without issue
- Crashes happen at a specific point, like opening a certain file or menu
- Crash reports mention the app by name repeatedly
Likely causes
- CommonAn outdated version of the app incompatible with the current macOSApp updates often fix crashes related to newer macOS versions.
- CommonA corrupted preference file specific to that appPreference file corruption is one of the most common causes of a single misbehaving app.
- PossibleA corrupted or incompatible file the app is trying to openSome crashes are triggered by a specific document or project file.
- PossibleInsufficient memory for what the app is trying to doResource-heavy apps like video or photo editors are more sensitive to this.
- PossibleA conflicting plugin, extension, or add-in within the appSimilar to browser extensions, these can destabilize the host app.
What to do
- Update the app to its latest version from the App Store or the developer's site.
- Check for macOS updates as well, since compatibility fixes often go both ways.
- Restart the Mac, since a fresh restart can clear temporary conflicts.
- Try opening a different, simple file in the app to see if the crash is tied to a specific file.
- Remove or rename the app's preference file (usually in ~/Library/Preferences, named something like com.company.appname.plist) and relaunch, which resets its settings to default.
- Disable any plugins or extensions within the app if it supports them, testing one at a time.
- Check Activity Monitor for available memory when the crash occurs, especially with resource-heavy apps.
- If crashes continue, uninstall and reinstall the app completely, or check its support forums for known issues with your macOS version.
Tools and parts
- None required
When to call a pro
For a specialized professional app, the software developer's own support is often more helpful than general Mac repair for crash-specific issues.
