Ha! Thats a stretch MacRumors, the graph clearly shows the difference as being .15%. Or basically nothing.
 
iOS-only developers also have access to Yosemite Developer Previews this year. That could account for the large increase.

I came to comments to make this exact statement. :)

Also, as a registered iOS developer, I was tickled pink to have said access to OS X. :D

My four-year old air slowed to a snail's pace with Mountain Lion. Too scared to drop a new OS on it. Guess I'll wait until I upgrade.

Really? I had a 2010 MBAir running Mountain Lion and never had any problems. Ended up selling it before Mavericks dropped, but I wouldn't have hesitated to upgrade.

If only 1 person was using the Mavericks DP last year, and this year, 4 people are using the Yosemite DP, that still makes it a 4x increase, does it not?
Just because the total amount of users is still less than 1% of the OS X market does not make the headline any less true.

But again, agreeing with others, I myself am using the DP because they allowed me to have it with my iOS dev account.

Yes, that's what happened to me. I have an iOS account, and then grabbed the 10.10 preview (to my surprise!)

I tested it on my 2008 alu macbook. It's crushed it. I have to roll it back to 10.9, it just can't handle the OS.

That’s unfortunate, I kind of expected that. :/
Are you using the 2.4 version? Upgraded RAM?

LOL. You're having performance issues, so you do what any reasonable person would do- refuse to install a free incremental update to Mountain Lion, called Mavericks, that focuses on performance and battery life issues. One proven in multiple third party tests to make even ancient Macs use dramatically less RAM and have longer battery life. One designed to get things done as quickly and efficiently as possible to get your CPU back to low power mode ASAP. Makes sense.

That's what I love about MR- it's where logic goes to die.

Didn't know Mavericks did all that. Thanks for letting me know, so snidely even!

Of course you knew all that. You, like all reasonable people, did your homework read the features and the review before making an informed decision that power and performance just aren't a good fit for you. You've been thrilled with the result- an entire year of weaker than necessary performance and battery life, just as one would expect.
 
a nice little tweak; nothing to do w/ developing really but hinting they are getting proud of their work--apple changes the "About My Mac" description from OS X v. 10.10 to OS X Yosemite.

Guess what...

I remember the exact same "OS X Mavericks scored higher usage." too OS X 10.9 came out..

The same thing happens with every singe OS.... Why wouldn't it ? Apple adds features people like..

It can happen to everything. Its getting old news quickly....

Its just marketing crap.... Nothing to worry about really.. People will buy it regardless.

Are you using the 2.4 version? Upgraded RAM?

2.4, only 4gb of ram because I can't find the 8gb pair cheap anywhere right now.

It was a lot of CPU load and fans blazing, ram should lighten the load.

I'm sure a few more betas it would get more stable. But it kind of reminded me of the Aero interface in MS Vista, sucking on the resources for some pretty interface.

Should run nice on my late 2013 Retina though (can't risk trying it on my main work machine though)

I’ve upgraded my RAM to 8GB.

Then again, developer previews have always been slower than release versions as they contain irrelevant code for release. Maybe it gets better. Still, at least we have the option to revert to Mavericks, unlike some other operating system. :p
