There are reasons for separate release dates, but servers aren't one of them. Yosemite downloads will be negligible compared to iOS 8 ones, the later having 10 times as many devices and a much faster adoption curve.

Oh I agree the ios downloads will far out number the Yosemite downloads but make mo mistake it isn't negligible. There will be millions of people downloading Yosemite the first few days it's avaliable. It certainly isnt a good idea to release both at once for many reasons and server load is one of them.

Is your bug to do with Tabs?
I cant tab in safari , Command+T does nothing :(
Macbook Pro Retina 2013 OSX Yosemite DP4

No my safari has just started lagging and crashing with as little as one tab open playing a video. It's new to beta 4 for me and is inconsistent.
 
Remember a few years ago, Apple released a new iOS, new iPhone and a bunch of other things (I think it included some online services) at the same time? It was a disaster. They were scrambling from one system to the other to deal with the technical problems. I bet they're thinking "never again".
 
EEEE! Flat Launcher Bar?!? Finally ... I won't have to hack around that anymore!
Or is that just an bogus screenshot showing features not existing in reality? :D
 
The (normally blazing fast) internet at my university was about dial-up speed last year when iOS 7 came out. There's no need to add more congestion to the world's networks by releasing iOS and Yosemite on the same day.
 
As a final consumer, I don't get why all the time. Apple is one of the best tech company today, with billions in cash. Just get dev's to get sh## done.
 
Maybe this is the reason for the public beta of Yosemite? So that the people who REALLY care can be on Yosemite when iOS 8 drops and the rest will get Yosemite a few weeks later.
 
Compressed memory is a lie. That piece of junk was making my system run out of RAM constantly. My computer was crawling until I downgraded it.

i was under the impression it was hardware based compression. my guess is your 2008 mac pro doesn't have the hardware for it and therefore it is trying to do the compression in software which would take a huge hit on the cpu. makes sense in this case to disable it.

sounds like... every year... only 'disaster' i can recall is apple maps.
 
Apple, take the time you need to release something stable. I'm perfectly fine with iOS 7 and Mavericks at the moment. It allows me to get things done without hassle nor bugs.
 
This is not a problem with me. Considering I tend to update on the first day (so I can be one of those early adopters that spread the word first-hand), separate dates gives me a chance not to go into total culture-shock with a dramatic change to two of my three everyday operating systems (iOS, OS X, and Windows 7).
 
Bluetooth?

Isn't handoff accomplished through bluetooth? Bluetooth is off on the iPhone and the iPad in the photo.

Is there a class action suit I can join?
 
I'm saying that anyone that complains about system performance that is still running a spinning platter has no leg to stand on.

Furthermore, you can expect to need to upgrade your hardware just the same for Yosemite performance, so you might as well do it now. You're only delaying the inevitable.

Yeah, I do. You're blaming hardware for software problems. Mountain Lion runs great because it's not programmed badly like Mavericks, and I'm sticking with it since there's nothing I use that requires Mavericks… actually it's the opposite since a few things I have won't go beyond 10.8. I'm delaying until computers are cheaper and faster.

I thought it was software-based, but if it is hardware-based, why is it trying to do it on my computer?
 
This launch is already a disaster.

First the Photos app for the Mac won't be ready until 2015, rendering "all my photos in the cloud" useless until then, except for the once I take on my iPhone on the iOS 8 lauch.

Now they OS's won't launch the same day so the big Yosemite feature, Continuity, is practically useless.

2 of the biggest features, not even available on launch day.
