IMac 20'' (2009) koppelen aan MacBook Pro 15'' (2012)

Question

Ik wil mijn nieuwe MacBook Pro 15'' uit 2012 kunnen koppelen aan mijn oude iMac 20'' uit 2009.
Ik wil de iMac 20'' als tweede scherm gebruiken. Dus dat ik met programma's (zoals Adobe Premiere) vanaf de MacBook Pro 15'' werk.
Ik lees dat dit niet mogelijk is, omdat de iMac 20'' uit 2009 komt. Is er een andere mogelijkheid door met andere snoertjes/kabels deze schermen wel te kunnen koppelen?
Ik hoop dat er een held is met een oplossing!

Answer 1

PS: side-by-side specs, graphics and drive data rates,
the newer of the two may be the better one to get, as
it has later Thunderbolt  with higher capacities, too.
Look into mactracker or other specification chart that
can be opened beside each other (as I have now) &
then you can see sections in each model, one at a
time. MacTracker shows general-software-memory+
graphics-connections-history by category.
2013 model Thunderbolt, Hard Drive Interface, graphics
spec all look good. Not sure if the history of graphic issue
in the dual-graphic card model 2012, was overcome or not.
However this may require some research...
If yours is one that shipped with Mavericks OS X 10.9
you may do well to get a copy of the installer on a
USB and dedicate it as a backup or set up a second
drive or other device to safe a download of the installer
and/or a copy-clone of the Mavericks. The limited total
of RAM available may not be a problem, with both units
shipping with an SSD and not a rotational HDD. And if
you like (& if yours has OS X 10.9) you could then use
OS X 10.10 too.  Be careful an 'upgrade' isn't done to
an older system by accident; surprises aren't so nice.
With either choice, be sure to get & make suitable backup
of your files in addition to a device to use Time Machine.
Good luck & happy computing!
