I told myself the day before public release I was gonna wait a few weeks. Then proceeded to download the first 30 minutes it hit the App Store.
 
I am pleased with Yosemite so far. There are some occasional glitches and bugs, but they are not more annoying than they were in [insert OS here]. That’s the risk of being an early adopter, I’m sure many will be corrected soon.

I got used to the theme after launching into the public beta a couple of times for several hours and it don’t have any second thoughts. Although I still love the Mavericks theme, Yosemite has its qualities too and seems to be a bit ‘lighter’ in use. Especially Safari is so nice with its compacter interface and subtle tab animations, it feels very fluid. Overall OS X is still OS X, there are few game breaking changes. Even the Dock is so quickly overlooked, despite of what you mind think of its new look.
 
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).

I've just upgraded to 8gb after installing Parallels, seems a little better, will also get an SSD to really get it steaming I hope, I've added them to my older PCs and they certainly make a difference.

Me too, but I wish I would have waited a few weeks with IOS 8, my iPad Air still hasn't fully recovered.
 
If you have a mac mini, get ready to a force-shut-down every time to you wake it from deep sleep if you have speakers attached. Been reported since beta 2 still not fixed!!!

Also, if you don't like iOS7 or 8 ... you probably won't like the iOS-ification of OS X under Yosemite with the extra transparencies, flat icons, ...
 
I guess it's best to have an SSD for this update, too. Ever since I bought my MBA in 2011, I'm always hearing people with Macs that still use hard drives complaining about almost every major version of OS X that it made their machines slower. Meanwhile, I never really experienced any noticeable difference in performance in the last 3 years (and I only have 4 gigs of ram). Guys who use older machines: swap that old HDD with an SSD and you should be fine with Yosemite. I don't think RAM is anywhere near as important as having a solid state drive.

What happened to the air? Between my 6 plus and Mac my air has the least amount of bugs.
 
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've just upgraded to 8gb after installing Parallels, seems a little better, will also get an SSD to really get it steaming I hope, I've added them to my older PCs and they certainly make a difference.

SSD makes a huge difference. Aside from very slow booting times, I also had a lot of ‘beachballs’ when logging in, waking from sleep or opening applications. I also remember reading that OS X has been optimised for SSDs for a while now. Honestly, the biggest improvement will probably come from the SSD. The RAM is important for multitasking and app launch times and you’re getting the benefits of 64 bit as well (Snow Leopard, though 64 bit, was purposefully disabled by Apple on the 2008 aluminium MacBook and only enabled since Lion. Since then you have a good reason to upgrade RAM beyond 4 GB).
 
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.
... yet Apple still sells a Mac mini with 4GB of RAM that is soldered, so can not ever be updated.
 
For once, what I perceive here isn't in line with this. I've only seen one person running Yosemite out of all the Mac users here. And so many people use Macs here, probably more than half.
 
OSX 10.10 Killed my iMac mid 2010 Grahix Card issue -screen now unusable

OSX 10.10 Killed my iMac mid 2010.

The graphics have become unstable and apple retail service can not figure it out, been down five days . one thought it was the graphic card drivers in 10.10 . It is unstable release and i regret installing it .

The Issue : Pink and green pixels when running Apple mail and safari , then kernel panics and dialog boxes that say graphics failure. somtims the screen the Gose black

Gets worse over time . But it dose pass the apple video test.

Apple after five days thought the only thing to do was wipe out my drive and re install the OSX . Really i tried that was with the same result . dam . they do not yet have current testing tools either . their is almoner to the story but it has been a big fail. :(:(:(:(:(:(:( anyone have any ideas

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.

... yet Apple still sells a Mac mini with 4GB of RAM that is soldered, so can not ever be updated.

It's not the RAM that wasn't enough... 8 GB, come on... my brother and sister both use MBA's with just 2 gigs of ram and they've never ever felt the need of more... It's that old, sluggish HDD. Swap that for an SSD and your iMac will reborn.
 
I guess it's best to have an SSD for this update, too. Ever since I bought my MBA in 2011, I'm always hearing people with Macs that still use hard drives complaining about almost every major version of OS X that it made their machines slower. Meanwhile, I never really experienced any noticeable difference in performance in the last 3 years (and I only have 4 gigs of ram). Guys who use older machines: swap that old HDD with an SSD and you should be fine with Yosemite. I don't think RAM is anywhere near as important as having a solid state drive.

Yeah, Mavericks without an SSD is terrible, at least on 10.9.0. It makes me wonder what the heck it was doing with my hard drive. It creeps me out, so even with an SSD, I'd much rather run Mountain Lion.

----------

I'm still on 10.6, LOL!

If it had iCloud integration, I'd call it my favorite version by far.

----------

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.

It's about adoption rate; there's no trick here. Why would people be less likely to update Windows just because more people use it?

Everything supports the older versions of Windows, usually even better than the new versions in fact. Nothing dares to be incompatible with 32-bit XP. Plus the updates cost money, and Microsoft supports the old versions. They don't act as if everyone is updating like Apple does. Dell still sells PCs with Windows 7 because people (rightfully) like it a lot better than 8.
 
I ran the Public Beta on a test machine, a 2012 MacBook Pro, and I was _not_ impressed with the experience at all. I was firmly against some of the design decisions that Apple made for Yosemite. However, I took a leap of faith when the Yosemite was officially released and upgraded my MacBook Air. I'm happy to say that I've adapted to Yosemite, with a few minor tweaks, such as switching to the Graphite colour scheme. Performance-wise, Yosemite can't be beat. It's amazing, and this is still a good ol' Mac, top to bottom. I just hope that some of the design decisions are continuing to be tweaked and refined.

----------

I told myself the day before public release I was gonna wait a few weeks. Then proceeded to download the first 30 minutes it hit the App Store.

Same here, but waited a few days. Then it took 3 days to download... that was painful. But it finally finished and all smooth sailing. Perfect install.
 
"I had to remove it from my early 2009 iMac. "

I'm surprised you could. My 2009 mini would not reboot snow leopard even after a time machine restore. I suspect a firmware modification, as the mini was originally limited to a 32 bit OS, which Yosemite is not.

A forced upgrade well before I would have done, if I had done it at all. I was trying it out on an external hard drive, then found out there was no way back.
 
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).

Both my MacBooks have 8GB RAM, but on earlier OS versions that extra headroom of RAM was used to help me run VMWare. So if Yosemite starts relying on that extra RAM for running smoothly, does that mean VMWare and Parallels are going to start to become inefficient on Yosemite because of RAM issues, even with my 8GB RAM?
 
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.

10.10 was in public beta so many of the problems have been worked out already (or saying another way-- 10.10.0 can sorta be seen as a .1 release)

more importantly, my 7 applications I use on projects are all Yosemite ready.
 
As with 10.8, 10.9, & 10.10, my mac pro is not compatible but still very capable. Staying with 10.6
 
12.26% of 1 Billion PCs is a lot more than 12.8% of 50 Million Macs.

That would probably be equally true for Android devices. They are significantly more popular in most countries, the US notably excluded. ;-)
 
Mid 2011 8GB MBP here. I have to say, I find Yosemite the best improvement to OS X in a long time. It feels solid and consistent they way iOS does. Far fewer beachballs and a just overall more crisp and refined. Even iTunes doesn't feel bloated for the first time in a long time.

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.
I doubt this is it. Are there really many people who like the Yosemite visual changes?

Same here. I upgraded because I wanted icloud drive and ios integration but I'm definitely not digging the style changes. I replaced most system icons and put some color in the sidebar but there are some things like overly flat UI that can not be easily replaced. They really went too far with this flat design IMO.
