Main Image is Terrible

The top / main headshot image is absolutely drab, and not commissioned by Apple as a good consumer or contributed image. Someone has changed the previous beautiful image to a drab one. Could be hackers. — Preceding unsigned comment added by 72.209.223.190 (talk • contribs) 08:29, 14 July 2015‎ (UTC)[reply]

Verbosity

Hi guys. I was just thinking that the History and PowerPC-Intel transition sections are far too long, because they are just supposed to be summaries of main articles rather than serving to replace them. Blythwood just did a ton of really admirable work in citing the whole article, and I didn't know whether that's new content or whether it's come from the main history article. If the latter, then that content and more, should basically go back there. Also I was thinking that the whole list of versions should be collapsed in the ToC. Thank you very much because this is a really great article. — Smuckola(talk) 22:42, 8 December 2015 (UTC)[reply]

Yes fair enough, when I was adding material there I was starting to wonder how to handle having a concise version here and a longer version in the History of OS X article. Will think about this - happy to welcome others' input as long as any content felt to be too much here is being moved over to the history article. Blythwood (talk) 22:53, 8 December 2015 (UTC)[reply]
@Blythwood: Hey there. So was that basically all-new content? Is it not redundant to History of OS X? I'm just asking because I don't know. If so, the most important thing is that you got it together and published, since it's so high quality. I'd say that the sections I mentioned should be about a quarter of the length of what they presently are, because they have main articles. They should just be a brief casual overview (like the main articles' leads) for someone who really doesn't care very much or else they'd read the main article. This article has a lot of such sections, but still a lot of completely unique content. Thanks a lot. — Smuckola(talk) 17:05, 9 December 2015 (UTC)[reply]
@Smuckola: Yes, on balance it is a bit redundant. I felt I should something there to describe general trends, for example the fact that early OS X reviews criticised it for being slow. I see now it would make sense to pare it down and move content into the history article, maybe the bit from 'Apple rapidly developed...' onwards - feel free to do what you want to it. Perhaps skip from there to ... From 2012 onwards. Blythwood (talk) 14:29, 16 December 2015 (UTC)[reply]

Rosetta

"PowerPC (10.0–10.5.8; PowerPC applications still supported on x86 with Rosetta up to 10.7"

It was up to 10.6.8. — Preceding unsigned comment added by 76.75.93.92 (talk) 23:40, 17 December 2015 (UTC)[reply]

You were right, fixed, thanks. — Smuckola(talk) 01:11, 18 December 2015 (UTC)[reply]
Whether it's correct or not, people use "up to" in both the inclusive sense (where "up to 10.6.8" would be correct) and the non-inclusive sense (where "up to 10.7", as in "10.7 was the first release where it's not the case", would be correct) - it means "until" in the non-inclusive sense - so it wasn't incorrect. It was, however, ambiguous, so your rewrite, avoiding "up to" entirely, is the right way to say it. Guy Harris (talk) 01:25, 18 December 2015 (UTC)[reply]

When was the "Mac" dropped?

The lead section says "OSX" was "originally Mac OS X", yet I can't find a single reference in the article when the product name change occurred. Was it ever officially called "Mac OSX"? — QuicksilverT @ 21:59, 19 January 2016 (UTC)[reply]

Never "Mac OSX", with no space between the "OS" and "X", but it was officially called "Mac OS X", with a space between the "OS" and "X", from Mac OS X 10.0 through Mac OS X 10.6, as indicated by Apple's pages for the OS from 10.0 through 10.6. For 10.7, Apple used both names; for 10.8 and later, they called it OS X. Guy Harris (talk) 22:24, 19 January 2016 (UTC)[reply]
