Guys, You dont expect to run windows 10 on your 2005 piece of stuff. This apple hate might seem "reasonable" and that all started back when they made one dramatic change; When they went from IBM power PC to Intel x86. That started this stuff fling fest that continues today. OSX updates are normally always free anymore, unless your hardware cant run it. To keep their OS as light as possible, they use exclusive instruction sets and modify their kernel for newer architectures. It simply isnt the same as windows, It is comparing a golden delicious apple to a fuji apple, it is possible... but not realistic. Windows discontinued support for windows XP and when they did that they disowned it entirely, any apps that were once usable with XP no matter what it was if it was made by windows are now not downloadable anymore, to include service packs and essential upgrades. Dont criticize some other OS because you want to cling onto your own stuff and fanboy about it. They are different get the forget over it.
They are not just an OS manufacturer, they are also a hardware manufacturer. Meaning they also have that side to struggle with, and they are going to do whatever makes money while keeping customers.
