For those wondering, no issues installing this on a 5K iMac. Whether the wifi issues are fixed on it ... - too early to tell.

FYI, you need to be patient on the install on the 5K iMac. The screen stayed black for what felt like a REALLY long time...

On the plus side, I can finally open Apple Support documents in Safari, which peculiarly haven't opened for me since upgrading to Yosemite. I'd always get a blank page in Safari, whereas Chrome/Firefox opened them fine.

e.g.

http://support.apple.com/en-us/HT201897

I can now view that. Yeah, really.
 
Try a clean install.

This. So much this. My 2012 cMBP became nearly unusable after updating from Mountain Lion to Yosemite. Safari was slow, the OS would give me the spinning beach ball for a good 1-2 seconds just to bring up the right click menu on the desktop, I couldn't type without the text stopping and then catching up after half a second of nothing happening. It also seemed like it was constantly banging on the hard drive every 2 seconds even though no disk activity was showing in activity monitor, but I could hear it. At that point I decided a clean install was the only way to go, and if I was going to that trouble I certainly wasn't putting it on that horrid 5400RPM Hard Drive. Enter the 1TB Samsung 850 Pro and a fresh install. I haven't had any issues since and the thing is stupid fast. Although, I am a bit upset at Apple for the issue they have caused with enabling TRIM on 3rd party SSD's...

I have the 5K, and can view that page fine in Safari and 10.10.1.Weird problem. Are other pages problematic?
 
Spotlight fixed

Haven't had much time to play with it yet, but i noticed immediately that spotlight search is now fixed and working as it should. Before it wouldn't load results half the time, you'd have to backspace and retype. :)

Nope! Just those Apple ones were.

YES. That was driving me nuts!
 
Try a clean install.

Unfortunately 50% of the machines are clean installs and problems remain, which is a problem experienced by a huge amount of people posting on these forums.

Even if a clean install did fix, then it's still completely broken as a release since if the install scripts are so broken they can't remove /upgrade /clean up even Apple's own drivers then it's a massive fail anyways.
 
You guys think OS X is buggy.... You should use Swift and Xcode :)

Though I do love Swift, even its silly beta self

Just checking to make sure you know about Trim Enabler. If so, carry on.
 
iMac 5k seems faster

I got a 5k mac with 2GB videoram. I had weird lag when cmd-tab switching between apps which was becoming quite annoying. A reboot would alleviate it for a while. 10.10.1 did not fix that. So I installed the 10.10.2 beta's and it does seem to help for each iteration.

I was just about seriously considering to downgrade to Mavericks or Mountain Lion due to these persistent wifi issues on both our MacBooks, an Air and a Pro. As it stands I will give this a try, before reconsidering.

The last OS that was flawless for me was Snow Leopard. I wonder if it is feasible to run such an old operating system and which aspects of the more modern ones would be missed. For me the lack of iCloud, app launcher and security updates are holding me back.

What do you guys think is the most reliable recent OS X version?

Mountain Lion. And Snow Leopard before then.
 
Could you please fix the terrible UI glitches? I run dual screens on a MBPr 15". If I'm running iTunes video in the main display with my code on an external monitor, the video blinks incessantly when switching windows. Also the menubar is constantly redrawing on the non-active screen with white blocks when using the dark theme.

The WindowServer process under Yosemite has been a huge culprit for performance problems, and I was glad to read that I wasn't alone. Some people had found workarounds. I can't remember the exact option that I changed in System Preferences, but I have noticed an improvement, so search for "Yosemite WindowServer" and you might find some help, as well.

Mavericks was perfectly decent in my book. Yosemite sucks. Never thought I'd say that about a Mac OS.

Is the Wi-Fi icon fixed with 10.10 ?

What i mean is in 10.9.5, sometimes u see your connected, yet the icon show its not... But u know it is, since u can get online.

Or the fact when take screenshots they thumbnail's displayed ??

Seriously Apple, some of these issues are laughable to the extent i really wanna use Windows.... You would never see this.

I do have 10.10.x in VM, but i can't test the Wi-fi thing in VM.

While I typically don't reply to such poorly written posts, I do want to say that Wi-Fi status has been fine for me under Yosemite for the most part. And I agree that many of these glitches never should've made it out in a public release. Apple should be ashamed, or at least be taking the problems more seriously.
 
check your router settings. make sure WMM is enabled. Some people tried disabling it to deal with oxs wifi issues... you will be forced down to 54mbps...

Thanks !

Seems that partially solved the problem !
Getting over 150-200 Mb/s now...
 
Man, Yosemite seems to be the worst OSX ever. Glad I haven't updated. Considering that I don't need to I'll probably skip it altogether.

Completely disagree. ML was the best, closely followed by Yosemite. Lion and Mavericks both were way worse, with Mavericks being the worst. Buggy, sluggish, and just plain odd behavior would sum Mavericks up nicely.
 
Bluetooth connection?

Hi!

Ever since I upgraded to Yosemite on my iMac 2013 I have had problems with my Magic Mouse and Apple Wireless Keyboard. It drops connection all the time, is this a known bug or is there something wrong with my Mac?

My late 2012 Mac Mini has the same OSX and keyboard and mouse but no problem with BT drops there. Really weird..
 
Maybe just my experience or not. I don't know, but I'm seeing continual and annoying kernel panic immediate shutdowns and failure to reboot properly under this release of 10.10.2.

Since I can't reboot 10X a day, I'm discontinuing testing of Yosemite until Apple fixes whatever they've done.

The kernel panics happen for no apparent reason and don't happy under Mavericks. At first I thought maybe I was having a technical problem with my Mac, but booting back to Mavericks seems to have solved the problem.

This happened infrequently in early releases, almost unnoticed by me while the Mac was asleep. Now it's just in your face. Can't explain it.

Sorry Apple, this dish is not well cooked! I will test the next beta, but I'm done with this one. It's completely unworkable and unusable on my Mac Pro.

My theory is that it has something to do with the graphics, since Yosemite has so many graphics glitches, yet none on Mavericks. Since I have multiple installs of Yosemite, I will check that the previous beta exhibits this behavior, but for now...

BE FOREWARNED IF YOU OWN A MAC PRO! This operating system is not ready for prime time nor anywhere near mission critical. :-(

I've had the same problem throughout the Yosemite GM and Beta program with plugging in an iPhone and the entire Bluetooth goes out. Only solution is a reboot. I've reported it. It doesn't happen in Mavericks.

So my only suggestion at this time is to go back to Mavericks. :-(

Apple REALLY dropped the ball on Yosemite on so many levels, it's depressing. It works perfectly for some with limited needs. Yet so poorly for so many others. :-(

Your name speak volumes... KoolAid.

Exactly the opposite is true and you couldn't be farther from the truth. Stop making false statements like this. I have multiple installs of Mavericks & Yosemite with the same software. I dare anybody to find Yosemite faster or more stable. You might be right that ML was just fine, but Yosemite is the worst Mac General Master release I've ever used EVER, at least since before Tiger!

the clean install line is getting old man!

Give it a break! Yosemite just plain sucks as a release!

It's the windows vista of 2014! :-(

The General Master sucked just as bad, so what's the difference?

If anything, Yosemite is getting worse with each beta since. :-(

I literally can't use the latest beta. Too many kernel panics. :-(

(Posted with Mavericks btw. I tried in Yosemite, but it froze too many times/shut down, kernel panic.)
 
In the mean time to get around the bug they had me disable OpenCL which means my computer has been very, very, very slow.

Are you sure that's what you did? Disabling OpenCL should not make everyday tasks on your computer slower. Only very few specialized programs even use OpenCL.
 
Have any of you experienced your cursor clicking a link when merely hovered and not actually clicked? This begin for me with Yosemite. At first I thought it may be a glitch with my 2012 MBP, but it's going on with my 15 inch 2015 MBP retina as well.
 
My WiFi issues are not MacOS related but rather Time Capsule related. I never had WiFi problems with the old Airport Extreme, but ever since I upgraded to the latest time capsule everything from the Old balck MacBook running 10.6 through to the latest MacBook Pro and a variety of non-Apple products have difficulty connecting to the Time Capsule.

Perhaps when reporting WiFi issues make sure you report Make, model, firmware version of your wireless router.
 
WiFi iOS Broken

Is anyone else experiencing WiFi issues since the last IOS 8 update? It was fine before, now it drops the connection when I wake from sleep. The worst part is, I have to reboot my device every time it does this just to get the WiFi to work again. It's happening with my iPhone 6 and now my iPad Air - which never had WiFi issues in the past.

You'd be better served asking in an appropriate thread for iOS, rather than this one about OS X 10.10.2.

No problem here with my iPhone 6+ or iPad Air. Might be your router? Try another WiFi at a friend or something and see if the problem still exist.
