It’s a perfect tool for helping you complete your design from schematic to the finished PCB in the shortest time and easiest way. EasyEDA EasyEDA is a free for electronic circuit design and simulation. Some of these software are designed to run on a Macintosh and some of them runs on different platforms. The following is a list of circuit simulator that works on Mac. So is there some good circuit simulator being used to design and simulate on Mac? It would be interesting for all of us trying to develop hardware on a Mac OS X.
