How do you get the files between macs?
There is no exporting from CS3 to CS6, CS6 should be able to open it.
But if it fails, yo can try to export as INX from CS3 and open this in CS6 and save as new INDD. Be careful, the INX must be saved at the same place as the INDD file is saved to find its linked images later in CS6.
thank you for your reply, i make a package from the indd file in my old mac at sc3 and mailing to myself and open it at my new iMac. am not sure what is inx... is it xml, indesign interchange?
thank you master ))
