Sorry, I missed your reply. Companies who design complex ICs, FPGAs, ASICs, and PCBs are using at least some tools from Synopsys, Cadence, Magma Design Automation and Mentor Graphics. This means Windows for some things and Linux for others. In some cases, these tools can run the customer’s choice of Linux or Windows, but many are one-OS tools.
Software tools in this industry don’t run on MAC OS, and the complexity of the tools and risk of a mistake in manufacturing means engineers need to run them in the approved OS build only, not a “compatible” one.
For example, I’ve seen a complex IC-design application that had issues in an unsupported, but by all descriptions perfectly compatible, linux release package but ran fine in the officially supported linux package.
Just answering you for trivia’s sake. Apple can forever exist profitably and successfully despite not being used on an engineer’s desk.
I again repeat: Windows running on a Mac in Boot Camp IS Windows... not "compatibles". You run the build of the Windows OS and it is that Windows OS.
Thank you.
