Cubase SX3 and Mac OS El Capitan


I work with Cubase Pro 9 on a MacBook Pro under OS 10.11.6.
I wish to import old Cubase songs and convert them into .CPR
Following Steinberg instructions I should use Cubase SX3 to convert these files.
Do you know if Cubase SX3 will work under Mac OS 10.11.6 ?
And do you know if eLCC 6.8.1 will recognize Cubase SX3 ?
