What does rebuilding Launch Services do?

It forces macOS to re-scan all applications and rebuild its database of app registrations, fixing corrupted app associations.

Is this a hardware problem?

No, it is a software resource issue. Restart, close unnecessary apps, and ensure adequate disk space.

Mac Error -10810 — Application Launch Failed (Process Limit)

Errorsystem

Overview

Mac error -10810 occurs when macOS cannot launch an application due to hitting the system process limit, corrupted Launch Services, or insufficient resources.

Key Details

Error -10810 from Launch Services means the app failed to launch without a specific sub-error
Can be caused by exceeding the maximum number of running processes on the system
Corrupted Launch Services database causing the system to mishandle the app
Insufficient memory or disk space preventing the app from initializing
Common after macOS updates or when many background processes are running

Common Causes

System process limit reached from too many running applications and background services
Corrupted Launch Services database losing track of app registrations
Insufficient system memory to spawn a new process
Application bundle corrupted or code signature invalid
Startup disk nearly full preventing virtual memory allocation

Steps

1Restart the Mac to clear process table and free resources
2Close unnecessary applications and background processes
3Rebuild Launch Services: Terminal > /System/Library/Frameworks/CoreServices.framework/Frameworks/LaunchServices.framework/Support/lsregister -kill -r -domain local -domain system -domain user
4Check disk space: Apple menu > About This Mac > Storage — ensure at least 10GB free
5If a specific app fails: delete it and reinstall from the App Store or developer website
