Not much response to your query, unkyUb, ......not many Mac users on here it would seem.
As I understand it, Macs will boot and load much more quickly than Windows PCs because of the different manner in which Apple organises the operating system. The MAC systems do not have a Registry in the same way as Windows......the Mac application keys being "attached" application by application rather than in one huge registry. This means that you do not have to hang around whilst an extensive registry loads...the appropriate keys only come into action as and when you open any particular progam.
As most viruses/malware attack Windows by infiltrating the Registry, the very lack of such in the Mac does make it inherently less susceptible to that sort of attack.
However, Apple do recommend that you have installed an AV prog.......as there is always the possibility of picking up nasties such as browser redirectors, hijackers etc.
Some Windows apps. can be run on Macs with a bit of fiddling.....a good read here
http://www.neilturner.me.uk/2007/01/05/running_windows_programs.htmlI think the problem with Macs lies with the hardware.
As you know, if you encounder a hardware failure or problem on a PC, you can walk into any computer shop and buy a replacement part or an upgrade component "off the shelf" and install it yourself.
Not so with Macs......their components are unique to Apple, obtainable (in the main) only from Apple.....indeed for some repairs you may have to return to Apple or an Apple designated engineer.
All this, IIRC, because Apple use a unique type of processor.
Not much of a help I'm afraid
....and I await someone telling me that I am talking nonsense.
