When I am trying to update macOS Sierra 10.12 to 10.12.6 update I have this problem:

macOS Sierra Update can't be installed on this disk. The volume does not meet the requirements for this update.

Error message

  • Pure guess... it needs more than 7 GB space to install – Tetsujin Sep 25 '17 at 15:18
  • I made it 20 GB but still the problem – Mina Mounir Sep 25 '17 at 19:47
  • I am facing the same problem but I guess it is because I have virtualized Mac OS Sierra under VirtualBox in Ubuntu... :( – Enrique Oct 20 '17 at 15:28
