When I open system preferences (iMac OSX Catalina 10.15.2) and open Desktop & Screen Savers the items under Desktop briefly open and then the tab becomes blank. I can't choose anything. When I quit System Preferences the and then reopen the same thing happens. Open Desktop & Screen Savers, items under Desktop briefly show up and then disappear. I'm left with a blank tab.

Try downloading and installing the MacOS Catalina 10.15.2 Combo Update. Sometimes this will fix these glitch issues. If it does not help, then you will need to reinstall Catalina.


Reinstall El Capitan or Later Without Erasing Drive


Please be sure you back up, if possible.


  1. Restart the computer. Immediately, at or before the chime, hold down the Command and R keys until the Apple logo and progress bar appear. Wait until the Utility Menu appears.
  2. Select Disk Utility and click on the Continue button.
  3. Select the indented (usually, Macintosh HD) volume entry from the side list.
  4. Click on the First Aid button in Disk Utility's toolbar. Wait until the Done button activates, then click on it.
  5. Quit Disk Utility and return to the Utility Menu.
  6. Select Install OS X and click on the Continue button.
