We offer a version of d'accord for the older operating system Mac OS X 10.4 (Tiger). Please give us a short note with your order of the d'accord trial version if you need a binary which runs on Mac OS X 10.4.

For best performance through 64-bit and multiprocessing, we recommend to run d'accord on the most recent operating system Mac OS X 10.6 (Snow Leopard) or its predecessor Mac OS X 10.5 (Leopard). You can find a performance comparison here.
