- Too many apps launching automatically at login
- Low available storage space
- A single app consuming excessive CPU or memory
- An outdated macOS version
- Corrupted system settings (NVRAM/SMC) on Intel Macs
Step-by-Step Fix
Restart your Mac
Apple menu > Restart. This alone resolves a surprising number of slowdowns and freezes.
Check for macOS updates
Go to System Settings > General > Software Update and install anything pending.
Check available storage
Go to Apple menu > About This Mac > Storage. Free up space if you're below 10–15% available.
Check Activity Monitor
Open Activity Monitor (via Spotlight search) and sort by % CPU or Memory to spot any app using far more than it should — then quit it.
Review your login items
Go to System Settings > General > Login Items and remove anything you don't need starting up automatically.
Boot into Safe Mode
Restart while holding Shift (Intel Macs) or holding the power button until startup options appear (Apple Silicon), to see if a third-party extension is the problem.
Run Disk Utility First Aid
Open Disk Utility, select your startup disk, and click First Aid to check for and repair disk errors.
Reset NVRAM or SMC (Intel Macs)
Restart and hold Option+Command+P+R for NVRAM, or check Apple's SMC reset steps for your specific model.
Reinstall macOS if needed
Restart into Recovery Mode (hold Command+R at startup) and choose Reinstall macOS — this keeps your files intact.
Still Not Fixed?
If your Mac won't turn on at all, makes unusual clicking sounds, or First Aid reports a disk error it can't repair, that points to a hardware issue that needs a closer look before you lose any data.
