Yes and No.
I said years ago that Apple would migrate the Mac to ARM. When it suited them. People laughed at me.
Perhaps big companies over use branding, like MS calling things "Windows" that are very different and may or may not be compatible for existing applications.
Apple "Mac" 68000, Power PC, x86 and recently x86-64 with 32 bit forbidden. Now ARM. Maybe all these families should have used different branding after the Mac 68K.
Also the Mac OSX is based on BSD via NextStep. A totally different (and better) thing to Mac OS9 and earlier. At least they didn't make the mistake with iPhone that MS made with PDAs and Phones and called the OS, iOS rather than pocket Mac OS.
