Six days after being made available to the public, OS X Yosemite was installed on approximately 12.8 percent of Macs in North America, according to adoption numbers released by Chitika. That's just a slight bit higher than the 12.4 percent of Macs Mavericks was installed on six days after its release in 2013.

Ahead of its launch, Yosemite adoption by beta testers and developers was more than 33 times higher than the adoption of Mavericks, and as measured by Chitika, its one percent share of North American Mac OS X-based Web traffic on the first day after release was double the day one adoption rate of Mavericks and Mountain Lion.

OS X Yosemite may be seeing slightly faster adoption rates as the operating system introduces a complete visual overhaul along with several features that allow it to deeply integrate with iOS 8. While Mavericks focused heavily on under-the-hood updates that improved battery life and responsiveness, OS X Yosemite brought revamped apps, Continuity, Notification Center improvements, iCloud Drive, and more. Chitika also speculates that the OS's public beta may have positively impacted its adoption numbers.
Apple had previously made a public beta of the OS available for the first time in the company's history, and this seems to have helped boost initial adoption rates slightly beyond what was observed for OS X Mavericks back in 2013.
Chitika's numbers are drawn from millions of U.S. and Canadian Mac OS X-based online ad impressions from the Chitika Ad Network. Chitika measured ad impressions from October 16 to October 22 to acquire its data. Similar but somewhat higher numbers are being reported by GoSquared, which offers real-time analytics that measure OS X traffic.

According to the site, Yosemite is installed on approximately 16 percent of Macs, though numbers fluctuated up to 10 percent over a seven day period as GoSquared measures real-time visits to more than 50,000 sites.

Still lower than I think it should be. I can understand though -- my parents don't even know what Mavericks / Yosemite is, and just stay on Mountain Lion (that came with their iMac). No doubt there's a lot of people that are just oblivious to free upgrades, not to mention many users that stay on older versions to remain compatible with specific software.

I had to remove it from my early 2009 iMac.

It wasn't running smoothly at all, got the swirling rainbow icon too many times. Slow, 8GB of ram was just not enough to handle it.

Mavericks was ok, still a bit slow.

Mountain Lion is where I ended up, perfect for what I need it for.

I'm staying on Mavericks on my 2012 Mac Mini, I like it and frankly I'm afraid to update. I don't need any more problems, the latest iPhone iOS 8 has been enough problems for me. I need some consistency.

I'm still upset that Apple forced iTunes 12 to update on my system automatically, I never wanted to update to 12 and I ticked the box not to update and it did it anyway.

Hate that they removed the ability to turn off laptop screens with a terminal command when connected to an external display.

For comparison, windows 8 and 8.1 makes up only 12.26% of all PCs. Yosemite outpaced that in less than a week.

Yea that 12.26% is part of a MUCH larger number. That's like there being only two Macs in the world and one had Yosemite installed. Then it would be 50%. Gotta love how they twist the truth.

I'm still on 10.6, LOL!

It's a good OS. I skipped the Lions and went to Mavericks. Still waiting until at least .2 or .3 for Yosemite.

Mountain lion and mavericks to me were a perfect upgrade, stable .0 release.
Not sure about yosemite with the new look, might wait for .2 or .3 releases.

Eh, weak argument. Nearly half a billion iPhones have been sold and more than half of all iPhones are running the latest OS.

And apple's software updates are easy and free, unlike windows.

Maybe if it actually installed...

Numbers would be much higher if the installer wasn't so borked. Lot's of people failed to install Yosemite, it was a dicey install procedure. Also Java has a major incompatibility and will slow down the fastest Mac to it's knees. Found that out the hard way after doing a fresh install after what I thought was a botched upgrade.

They don't twist the truth at all. Just because it's a smaller sample size doesn't mean what they say aren't facts. Your example is a strawman at best. They aren't 2 macs, there's millions. More than enough to gauge how adoption rates compare to windows.

I've updated my 2012 Mac Mini, can't say I've had any problems so far, don't like the look of the new icons too much. Since updating I've added Parallels, Windows 8.1. Windows TP and added an extra 4gbs ram and everything seems to be running smoothly.

That's funny, Windows 8 8.1 have bigger numbers than all the Macs, but they certainly like to make it look good.

I have a Mid 2010 iMac i3, and I have no issues what so ever using Yosemite! I use FCPX and Aperture. I actually like the new look and feel, but what does that matter? I am just a normal user, who looks at the positive, and I do not concentrate on the negative.

Just my 2 pennies

After upgrading my iPad to iOS 8 and hating it so far, no way was I going to update my 2013 MBA to Yosemite. I probably will not upgrade until I get a new computer.

I would install it but I'm unsure if it will affect performance on my 08 unibody MacBook.

It’s mostly the same as Mavericks. If you haven’t installed Mavericks either, then I don't recommend updating unless you have an SSD and a solid base of RAM (I have 8 GB).

Older mid 2008 MBP 17" 4.1
Put in OWC memory to the limit and an OWC SSD, it's like a new machine.

Yosemite running w/o any hic ups so far.

Yes, important SSD highly recommended. Great startup time.

Have the older HD startup disk as a 2nd drive in mine and if I reverse startup etc. in Mavericks it crawled.

I have the following MacBook Pro and Yosemite installed fine. See below:
Damn, this machine is 6 years old!!!:eek:

MacBook Pro (15-inch, Late 2008)
Processor: 2.93 GHz Intel Core 2 Duo
Memory: 4 GB 1067 MHz DDR3
SSD: 256

Give it a try.

My recommendation is to hold off downloading it.

It's not THAT much different, and it's "hard crashed" on me around 3 times a day in the last week (grey screen of death - requiring a full reboot)..

Wait for the patches imho

I usually wait also, but it was too tempting to try it. After all the "gates" I figured they got this one right.
