CCP will only run in Windows. However, it will run on a Mac if you have Parallels and a Windows virtual machine. If the Mac is an M1, M2 or M3 processor you will need Windows 11 for ARM which is about $200. A regular version of windows won't run. You can download Windows 11 during the installation of Parallels. I run the Standard version of Parallels which doesn't have an annual subscription price. I just switched to Mac silicon earlier this year and have Parallels 18. 19 is out but I don't need to upgrade. Won't upgrade for several years.
