I use C6.5 and not Artist but on a Mac these files/folders should be in the same place.
~home/library/Application Support folder
save a copy of the 'Steinberg' folder.
save a copy of the ' Cubase Artist 6' folder
When you get your new 'puter, install Cubase Artist 6 on it and
then put these copies in the same place(s) as in the old computer,
then install any 3rd party software
and 'bob's yer uncle'
HTH (hope this helps)
If yer gear ain't breakin down, you aint workin' much.
