Other Thoughts:

I. Restart your Router:

Unplug your router for 30 seconds, and then power it back on. Sometimes, there is a spike in electricity, and items become interrupted. Also, contact your Internet Provider, as they provide the service - perhaps there was utility work down the street from your location.

II. Reset your SMC and your NVRAM:

Sometimes changes are made to the system and then settings (i.e. for macOS) become manipulated, in the technically. So, reset both on your Mac. See if it now works as intended.

• How to Reset NVRAM or PRAM on your Mac - Apple Support

III. Boot into Safe Mode:

Boot into Safe Mode (Hold down the Shift key upon boot). See if this still occurs. In Safe Mode, items open by default and login items do not open after login, with all caches are set aside. See if it then works. Then, restart the Mac, and log in to the same user as you are in now. See if it now works. Logging into Safe Mode may fix a few things.

IV. Rid of Running Items:

Boot into Safe Mode, and rid of whatever is not needed as a Login Item

A. First check. the list of Login Items:

1. Go To: System Preferences
2. Select: Users & Groups
3. Click: This user name
4. Click: “Login Items”
5. Select: Uneeded items.
6. Click: “-“ button

B. Then, Check Force Quit:

See if an application is not responding. If that is the case, Force Quit it.

1. Go To: Apple Menu
2. Select: Force Quit...
3. Select: An Item Ending in: “Not Responding”
4. Click: Force Quit button

V. Verify your Drive: Repair your Disk in Disk Utility

Go Here: If your Mac Starts Up to an Apple Logo or Progress Bar - Apple Support

See if your Hard drive is Failing:

1. Boot: into Recovery Mode (Hold Down: [command + R] upon boot)
2. Select: Disk Utility
3. Select: the Drive
4. Click: First Aid button
