I Am Incredibly Strong & And Handsome
I don’t currently use macOS, but macOS support is typically about 7 years, sometimes up to 10. Apple supports the 3 latest versions of its operating system.

This might be an unpopular opinion here, but it’s not a myth. If you have hardware that isn’t widely supported it can require some serious technical chops to get things working. Open source is wonderful and a net positive but it can also lead to quite a bit of abandonware, which leaves novice users in a tricky position when things stop working correctly.

You, in fact, cannot install Windows 10 on a Pentium 4.
