Some Thoughts:

A. Try Safe Mode:

[Hold Down command key + R key] simultaneously upon boot. In Safe Mode, corrupted system setting files (caches), are intentionally fixed, and login items do not open at login.

  1. Boot: in Safe Mode
  2. Log In: as Same User
  3. Wait: 30 seconds
  4. Shut Down: the Mac
  5. Wait: 30 seconds
  6. Boot: the Mac normally
  7. Log In: as Same User
  8. See if can get this to work


If that does Not Work...:


B. Try a New User:

Single out this current user. You would create a new administrator user and the log in to it. See if you can perform everything as intended while logged into it, and if no errors occur. If nothing happens in this new user, then it is likely something misconfigured in this current user.
