Is your MacBook or iMac crawling? We clean up startup clutter, clear cache, and optimise your system — back to full speed, same day.
Slow Mac Tune-up
Here's exactly what our technicians do when you book a Slow Mac Tune-up with ErrorFix4U.
Full System Diagnostics
We run a complete health check on your Mac — CPU usage, RAM pressure, disk health and temperature — to pinpoint exactly what's slowing it down.
Startup Optimisation
We identify and disable unnecessary login items and background agents that launch at startup and drain performance before you even open an app.
Cache & Junk Cleanup
System caches, browser caches, temporary files, and log bloat are safely cleared to free up storage and reduce system load.
Storage Management
We identify large and duplicate files, clear the Downloads folder clutter, and advise on storage best practices to keep your Mac running lean.
Background Process Management
Runaway processes and memory-hungry apps are identified, terminated, and configured to stop hogging your CPU and RAM in the background.
Software & Security Update
We ensure macOS and all critical applications are up to date, and verify that your security settings are correctly configured for optimal performance.
