If your Mac displays a flashing question. The folder with a question mark icon means that your startup disk is detected or the Mac hard drive doesn't contain a usable Mac operating system. Mac can't find the startup disk or the system folder because of software or hardware errors, which brings out the blinking file folder at startup on your Mac. Create a new admin user account on your Mac and see if you can successfully download and install Origin in that account. Reinstall your operating system. This may seem extreme but you may have corrupted or missing files and permissions which could be causing this error.


If the question mark appears only momentarily before your Mac starts up normally:

  1. Reset NVRAM.
  2. Make sure that your preferred startup disk is selected in Startup Disk preferences.

If the question mark persists, follow these steps:

  1. Press and hold the power button on your Mac for up to 10 seconds, until your Mac turns off.
  2. Turn on your Mac and immediately press and hold Command (⌘) and R to start up from macOS Recovery.
  3. While in macOS Recovery, use Disk Utility to repair your startup disk.
  4. If Disk Utility found no errors or repaired all errors, reinstall macOS.
  5. If you still need help, please contact Apple Support.
