What does error code -2006F mean?

Hi DizzyJuneBug

Welcome to the Apple )user-to-user) Community.

Wondering where this code is turning up, (eg: associated with an app ?)

and

what you were doing on your Mac when the code appeared. (eg: updating / restoring)

Eg: Code is not listed in the Finder and iTunes Error Codes:

Find an iTunes or Finder error code - Apple Support

The above article does have a few tips: you might want to browse through it.

All the best :-)
