What is the latest OS and iMac model that would support CS2?

Question

I'm trying to figure out how to go about selecting the "right" iMac to suit my current needs and means. Like many folks (I'm guessing), I don't have the money to upgrade every time a)apple comes out with ANOTHER new generation of iMac/OS b)Adobe comes out with updated versions of their software suites.
What I need to know is:
1) Do the current iMac Intel CPU's (or the newest Mac OS) support software as old as Adobe CS 2?
2) If the current iMac's no longer support my software, what is the most current generation of iMac's to do so?
3) I would like to connect an additional monitor (I have an older 17" apple cinema display) to my iMac. Can anyone suggest iMac models that would accomodate my need?
4) Any suggestions of reputable sellers of older generations of Apple products, new or refurbished? Any sellers that should be avoided?

Answer 1

1) Yes and no. Yes CS2 will run on Intel based Macs but the performance may be a bit slower. The next problem is that Adobe does not fully support CS2 to run in Leopard. It will run but you might come across small glitches once in a while.
2) To avoid the Leopard compatibility issue you would need an ALU iMac from 2007 or earlier that comes with OS X 10.4(Tiger).
3) You would need to purchase two adapters. A mini DVI to DVI connector and the ADC Power adapter for the display which is about $100.

4) I would prefer an Apple certified refurbished iMac but they may not have one old enough for what you want.
If you don't have the money to upgrade everything including your software you might consider purchasing a used G5 tower. That way you can run Tiger and CS2 without any problems and still use your current LCD without having to buy any expensive adapters.
