Remove login items to resolve startup problems on your Mac
Login items are apps that open automatically when you start up or log in to your Mac. Occasionally, a login item may cause a blank blue screen at startup or other problems. You can test your login items to see if any are causing startup issues on your Mac.
Note: To print these instructions, press Command-P.
On your Mac, choose Apple menu
in the sidebar.Click Login Items & Extensions. (You may need to scroll down.)
Make a list of the login items in the Open at Login list—you’ll need to remember them later.
Select all of the login items, then click
.Choose Apple menu
If this solves the problem, open Login Items & Extensions settings again, add the login items one at a time, and restart your Mac after adding each one.
When the problem occurs again, follow the steps above to remove only the last login item you added.
