How to Fix Slow Startup on Mac

What Causes This?

Slow startup on a Mac is usually caused by too many apps launching at login, low free disk space, or background processes that take too long to load. Outdated macOS versions, failing startup disks, and heavy menu bar utilities can also increase boot time. In some cases, junk files and cached data make the system work harder than it should during startup.

Common Symptoms

• Your Mac sits on the Apple logo or progress bar for longer than usual
• Apps begin opening immediately after login and slow everything down
• The desktop appears, but the Mac stays sluggish for several minutes
• You see frequent spinning beach balls right after startup
• Restarting or powering on takes much longer than it used to

How to Fix It Manually

1. Remove unnecessary login items

   1. Click the Apple menu > System Settings.
   2. Go to General > Login Items.
   3. Under Open at Login, select apps you do not need at startup.
   4. Click the minus (-) button to remove them.
   5. Also review Allow in the Background and disable items you do not recognize or need.

2. Free up storage space

   1. Open the Apple menu > System Settings > General > Storage.
   2. Wait for macOS to calculate disk usage.
   3. Remove large files, old downloads, and unused apps.
   4. Empty the Trash when finished.
   5. Try to keep at least 15-20% of your startup disk free so macOS has room to work efficiently.

3. Update macOS

   1. Open Apple menu > System Settings > General > Software Update.
   2. Install any available macOS updates.
   3. Restart your Mac after the update completes.
   4. Updates often include performance fixes that improve startup speed.

4. Check Activity Monitor for heavy background apps

   1. Open Finder > Applications > Utilities > Activity Monitor.
   2. Click the CPU tab and look for apps using high CPU after startup.
   3. Click the Memory tab to spot apps using excessive RAM.
   4. If a non-essential app is consuming too many resources, quit it and consider uninstalling it or removing it from login items.

5. Start in Safe Mode to test startup issues

   1. Shut down your Mac completely.
   2. On Apple silicon Macs, press and hold the power button until startup options appear. Select your disk, hold Shift, then click Continue in Safe Mode.
   3. On Intel Macs, turn it on and immediately hold Shift until the login window appears.
   4. Safe Mode disables certain startup extensions and clears some system caches.
   5. If your Mac starts much faster in Safe Mode, a login item, extension, or third-party software is likely causing the slowdown.

6. Run Disk Utility

   1. Open Finder > Applications > Utilities > Disk Utility.
   2. Select your startup disk.
   3. Click First Aid and let it scan for file system issues.
   4. Restart your Mac after the scan finishes.
