Apple says it does.
More like it requires them to go to their code, and change a memory location with the Number "10" to "-1" or something.
What is your assessment of how easy it would be based on?
Apple is technically correct if you call changing a couple of lines of code "Creating a New Operating system."
It is a deceitful method of concealing just how easy it is. Saying "create a new operating system" implies horrific levels of difficulty, but the truth is, every time they compile their latest code, they create a "new" operating system.
Once again, Technically correct, but grossly misleading.
What is your assessment of how easy it would be based on?
The fact that the development of software which is capable of counting to number "10" does not normally incorporate complex issues of coding.
