How Can a User Fix MacBook Pro Slow Startup?

The first thing to discuss is why one’s MacBook Pro starts very slowly. “My Apple computer is starting so slowly I almost fall asleep, but it performs better after the bootup.” In this case, the problem is most probably caused by the startup and login items that launch along with your computer.

A user may easily solve the problem with startup items with the help of System Preferences. Move to this location to open Users & Groups. Then, you should simply pick a username, and end up with the Login Items tab.

An experienced user may apply Terminal to get rid of the login items that may be causing the slowdown at the startup. Start by typing this command: $ open ~/Library/Preferences/loginwindow.plist.

Users who move to macOS High Sierra complain about sluggish startups as well. Erasing startup files may not help in such situation. Just leave your computer switched on for about 24-48 hours. Reboot several times to see whether the method works. In case nothing happens, activate TRIM. It will take less than a minute. Just launch Terminal and enter the given line along with your password once you are done: sudo trimforce enable.

In case the problem is associated with the disk permissions, confirm and repair them using Disk Utility. Once you launch this built-in utility, go on with the following:

  1. Pick the startup disk.
  2. Choose the First Aid tab.
  3. Push the Verify Disk Permissions There, you can find Repair Disk Permissions.
