Well in theory the Android is Open-Source so it should work everywhere, even if patches are required. I just avoid Windows and this is my "up yours". The same with Linux. FreeBSD is my choice and I feel best here, I do not really care about other OS and have nothing to prove to anyone, apples and oranges :-) > The fact you are virtualizing at ALL is a knock against the host OS as > it's basically an admission that the host OS does not have what it takes > to get the work done so you have to go to the trouble of creating a > virtual guest with a REAL os in it. Except the "Open-Source" part that is tied by some company to a binary releases and does not accept patches to make things work on other OS ;-) The best solution for mobile apps development would be a modern macOS machine, but decent configuration cost around $7.5k here (MacStudio 20xARM CPU 128GB RAM) and it has predefined lifetime (my MacBookPro 2015 stopped at macOS 12.6.5 while macOS 13.3 is out and that impacts XCode development tools too). This seems a necessary cost. Well, goodbye free applications. --=20 CeDeROM, SQ7MHZ, http://www.tomek.cedro.info
