[Solved] Why Is My Mac so Slow?

Common Problems

Storage Overload: A nearly full hard drive or SSD forces your macOS to shuffle data constantly. Check your available storage space.

Click the Apple Menu –> About This Mac –> Storage tab

Memory Pressure: Not enough RAM makes multitasking slow because your Mac starts heavily relying on slower storage. Open “Activity Monitor” (Applications –> Utilities) and check the “Memory Pressure” graph. Green is good, yellow shows strain, red is bad.

Out of Control Apps: A rogue program could be taking over too much of the CPU or the memory. Activity Monitor’s CPU, Memory and Energy tabs can show you resource hungry apps.

Outdated macOS: Newer versions of macOS have performance optimizations. Check if you’re up to date (Apple Menu –> System Settings –> General –> Software Update).

Background Clutter: Too many startup items or hidden background tasks can slow down your Mac. Go to System Settings –> General –> Login Items and review both User and Shared sections.

Hardware Limitations: Older Macs eventually struggle with modern software demands. Your Mac’s model and specs play a role.

Other Troubleshooting Ideas

Restart: The classic fix for a reason. It clears temporary memory issues.

Close What You Can: Close unused apps. Every browser tab eats a bit of RAM.

Check for Updates: For both macOS and any major apps you use.

Free Up Storage: Aim for at least 15-20% free space on your drive. Delete old files, offload stuff to the cloud or try getting a larger drive.

NVRAM Reset (Rare): Look at Apple’s support site for instructions on resetting NVRAM. This can sometimes fix odd performance issues.

If Problems Persist

Disk Health Check: Go to Applications –> Utilities –> Disk Utility and run “First Aid” on your drive.

Hardware Diagnostics: Apple has built in diagnostics. Restart your Mac while holding the “D” key to run them.
