For the last fourtenn years or so, I used the Atlas RTS software (too many versions to remember) to design and modify my layout. I also played with it to create some small layout plans. Last month, I bought an iMac to replace my old PC. I still have the RTS files but can't read them, less print them.
Is there any software I can use on the iMac that can read and use RTS files?
