No, CoteDAzur - I may have wider experience than some, but to be frank, quite a lot of network problems, in my experience over recent years, are to do with Wi-Fi with security, signal strength, and other issues.
""This program wants to run, do you want it to?" etc. "
Maybe a bit of a faff but intentional to reduce the instances of a bit of malware installing itself quietly, so a rather good move, after years of little nasties getting on PCs because someone went to a site giving away wallpaper, fonts, emoticons, etc and you had to install their software with lots of small print, but one or two clicks and it was done without this type of warning for the user.
"with a Mac, it all just works." to which I'd add " the way Apple requires, or you're stuffed"
Of course there are third party sources for software, but Apple has kept a stranglehold on what they allow users to do. It seems odd that they could "on a whim" decide some apps for the iPhone or iPad are unacceptable, not just warn the users that they disapprove, and why :
for example - there was a video/audio player and Apple decided it would be unsuitable for mobile networks, so banned it, without the users having a say... If I've paid extra for my 'unlimited internet' contract with my mobile network, why should Apple say I cannot use some App when I am buying just their phone... Oh, OK, I see, I'm buying their phone and their rules too, I suppose...
Incidentally, if you ever started a terminal session on a Mac running any version of OS X, you'll be in a linux environment.
Apple had presumably got to the end of the line when they had finished Mac OS 9 (and when that change to OS X took place, some people with very expensive software could not upgrade for months because the software firms presumably didn't get OS X to play with early enough and therefore drivers were delayed... all to do with Apple keeping control, I guess).
