Calculators for Mac Os

[3298]

I know you are somewhat familiar with a 50g, so I think an emulated one shouldn't be too bad despite your stated preferences about emulators...
x49gp should work on Mac. That gets you a 49g+ or 50g, depending on configuration. 50g is the default one; the differences are minimal though, consisting of a slightly different bootloader used for building the initial flash image, and the visual appearance of the emulator. The other differences between the actual calculators do not apply: trying to implement USB power supply and keyboard feel is pretty pointless, and the communication ports are not implemented anyway. (Well, there is the SD card emulation for at least some way of moving data in and out of the emulated calculator, but USB, serial, and IR are missing.)
There are some snippets of code in it which are explicitly designed for Mac compatibility, so I think Macs are officially supported. (Some tests for Darwin as OS in the Makefile, another test for Linux in ./newconfig which I reversed in my local copy to a Darwin test because that's what it really should be (otherwise there could be issues on not-Mac, not-Linux systems), and an #ifndef __APPLE__ somewhere in the source code for key definitions.)
