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.

In some situations, it may be important to detect corrupted preference files and update them in the ~/Library/Preferences folder.
