[Solved]Chess game without time limits

Hi there,
odd request, but here goes. Me and a friend want to have a chess game, without any time limits, that we can acces and play, over several days/weeks. Is there a site or program for this? Also, if it’s a program, it should be compatible on both pc and a mac please.
As always, help is very much appreciated!
