Full disk access - failure (Mac only)

When the relevant setting is enabled, this error message appears on Macs when IIB does not have the "full disk access" permission in the "Security and Privacy" settings”.

  2. Click the “Retry” button in IIB.

If this does not resolve the issue then:

  1. Navigate back to the settings page for full disk access.

  2. Unselect and re-select IIB in the list. When prompted to close IIB, choose the option “Quit and reopen” instead of “Later”

  3. If the check fails again, then close IIB.

  4. Go back to the settings and remove the access provided.

  5. In the settings, provide access to IIB again.

Obsolete app version



App version - failure

  • Contact your institution to request a more up to date version of IIB.
  • Uninstall the old version of IIB and then install the newer version


Clock accuracy error



Clock accuracy - failure

This error appears if your computer clock and global clock do not match. You may need to ensure that your clock is synched to the correct global time.

  • If you have manually set the time on your device, you may need to instead sync your clock with a global clock server. 
  • Try opening the date and time settings on your device and synching with the Windows or Mac Servers.
  • Sync the device clock with a new server. Inspera uses Google's NTP server:
  • You may need to allow access through the firewall: NTP is on port 123 and TCP & UDP.
