Good point hollowface (preinstalled), and one I'd not considered .. it might be interesting to go through the two forums and see how many topics are installation related (even where only tenuously)
Yep, that is a good point. Also consider that not only is Mac OS usually installed in a factory but is installed on hardware that's built for it, whereas Linux is usually installed by home users on hardware that's built primarily for Windows.
Yes, and that hardware that's often inferior & costs more than two Windows computers of equal specs, is also a huge reason why. So are many preinstalled Linux computers, that's why it's best to purchase a Windows computer & convert to a Linux one (especially if notebook). Given that one doesn't have to purchase a Windows license to build a Linux computer, the cost of building is lowered further.
I believe the strongest reason as to why there's more Linux Topics boils down to economics. Not everyone can afford a 5 year old Mac, let alone a brand new one, and Windows computers, plus self builds, typically costs far less for better hardware. Anyone who tries to sell me a $2,000 computer of any type, that doesn't ship with a quad core i7, I'm going to laugh in their face, if a person to person sales attempt. Because for that price, a quad core i7 of powerful specs (minimum base clock of 3.5Ghz with 3.9GHz or higher Turbo Boost), 32GB RAM & 4GB or higher GDDR5 GPU should be standard equipment. Anything less would be considered an insult to my intelligence.
That's another reason why more doesn't turn to Apple, is the hardware for the dollar. Any computer over $1,200, i3 shouldn't be on the same page, and if i5, better be an unlocked K model. And Intel 5xx HD (or even 4600) graphics? On the Passmark charts, even ancient AMD 2xxx-3xxx series cards rank higher. So much for gaming w/out a discrete card.
Another reason why there's fewer Mac posters is that they have their own communities, kind of like the many dedicated Linux forums, so it's not surprising that more Linux users are posting.
Finally & the best for last, there are those of us whom have reshaped this Community in the last 12-18 months with a lot of hard work, and this was designed to attract & maintain Linux members to our site. That Bleeping Computer also fully supports Linux users also, and with welcome arms.
We don't bash members just because they're dual booting with Windows 'while learning', as many of the dedicated forums does, in fact, it's a violation of the rules to openly bash members, regardless of reason. It's mainly the dedicated forums that are keeping Linux usage down by treating newbies the way they do, and unfortunately, not all will find our Community, and will return to Windows.
At any rate, am glad to hear we're getting more exposure, as shown by the increase in recent Topic frequency. That's what we were & still are working hard to do, and will not let up. We're showing further up the chart on the Google's 'hit list' of Linux forums, and that's good for everyone.
