Hello I purchased Photoshop CS2 in 2006. for Macintosh. Now I changed the Maverick version 10.9. But now I do not know where to download the same version, so I use bought in 2006 key. When pulled CS2 can not install it because my version is higher. Thank you in advance for your reply and help.
CS2 was a PowerPC based application.
MacOS 10.9 won't run on PowerPC systems, and no longer supports the Rosetta emulation of PowerPC processors.
You will need an Intel native version of Photoshop to run on your current system.
