That argument doesn't make sense because you can do that in just about any modern OS.
1. Windows, Windows+R type "powershell"
2. Linux, Terminal shortcut (CTRL+ALT+T in Ubuntu)
3. ChromeOS has a terminal too, but it's very unlikely it would be affected by an issue like this seeing as it doesn't actually run binary applications.
then run your commands.
P.S. Mac OS is based on BSD, which while being POSIX-compatible is not Unix. It's a Unix-compatible clone. Berkeley even got sued over it and won because they didn't use the Unix source code. Heck you could even argue that Mac OS isn't really BSD either because it uses the Mach kernel. The architectural history of Mac OS X is really interesting and can't really be summed up in the statement "based on Unix". If you want to be that direct it's really based on NeXTSTEP, the OS built by Steve's other computer company.
