Oct 25, 2014 6:25 PM in response to Master26Aby Walry,I was also having speed issues with Yosemite. It was lagging a fair bit and graphics performance wasn't great. I also noticed a decent drop in battery life.
I've rolled back to Mavericks and it seems back to normal. I'm running a mid 2014 Macbook Pro retina with 256gb SSD drive so I thought it should have handled the new OS better, but unfortunately not. I mainly had to roll back because I just found out some of my audio software wasn't compatible, but apart from that I likely would have rolled back anyhow due to performance. I'll wait for a few updates and try it again after updating my audio software.
Also, the flat look doesn't look good for me, I'm trying to get away from Windows, not be with it again

Oct 25, 2014 6:31 PM in response to clintonfrombirminghamby {rez},A most interesting recommendation - ignoring all other's problems including WiFi - you must be living in a cave.
Faulty installs...bad system specis - these are the excuses of apple employees or narrow visioned fanboys - apple has screwed up a little bit, and call them out for it -
To the poster that experienced problems - it is completely your own fault for installing Yosemite right away - you should've waited for any kinks to be ironed out -
So yes, I think this is the fault of those who install the system right away without allowing fixes to be released first, it is the fault of those who just love to somehow pretend apple can't do anything wrong, and somewhat the fault of apple itself for not ensuring major issues such as wifi are working for EVERYONE on 5 Ghz and 2.4 Ghz.

Oct 25, 2014 7:09 PM in response to {rez}by Barney-15E,If it is so full of bugs, can you explain why it works flawlessly on so many Macs, including mine?

Oct 25, 2014 7:41 PM in response to Barney-15Eby {rez},Have you ever thought that the problem is being produced in a different way, maybe you are using your OS differently but other users experiencing it are using it differently as well although legitimately with functions that are supposed to work.
Or should I rephrase the question:Mine has bugs, I submitted them to apple. Can you tell me WHY mine has bugs?

Oct 25, 2014 7:42 PM in response to Barney-15Eby spidermark,NO. I am not a techie, so no idea why it works so well on some, but not on others. But, I have heard of many people uninstalling it, and reverting back to Mavericks. Mine is very slow. Have alot of lag time. The folders I am trying to open are local, on my desktop. Nothing appears in a folder that has 40 sub folders, with 3,000 images total. Nothing. Sometimes the images and folders eventually show up, sometimes not. Never had an issue like this with mavericks. it was flawless. Yosemite is not.

You’d have to show me everything you have installed, especially startup/login system mods.

Oct 25, 2014 8:20 PM in response to Master26Aby IBRA_LBY,I have Macbook 13" Retina 256 SSD Cori5 8GB Ram. I think the new performance of my Mac is went down since I updated to Yosemite. It's exactly like what happened to my iPhone 5 when I updated to IOS 8.

Oct 25, 2014 8:50 PM in response to spidermarkby Walry,I'm not sure to be honest, I'm new to Mac so I've not had much experience with TM. What I did was held down Option, Command and R at startup. If you only use Command and R it will still download Yosemite again. So, boot with Command, Option and R and then erase the drive, then it will allow you to go back to whatever OS was shipped on the machine.

Oct 26, 2014 7:20 PM in response to IBRA_LBYby NeoNirvana,Alright, I posted here complaining about many of the issues that have since been reiterated, so I thought I'd clear up how I fixed it. Bear in mind that I'm running on a mid-2010 MBP. Here are the problems I had:
1. Extremely poor performance, lagging in Finder along with all other apps, frequent system freezes. This was resolved by restoring the disc to factory settings (erasing the entire HD), re-downloading Yosemite and doing a clean install of it, followed by a data migration from a Time Machine backup.
2. App Store was broken. This was because I downgraded to iTunes 10.7, and for whatever strange reason, it turns out that doing so effectively destroys the App Store entirely. Reinstalled iTunes 12, entered a Terminal command to make it black for personal taste, and the App Store is running perfectly again.
3. Photoshop CS6 was running abominably, and causing regular system freezes. Apparently when using newer Mac OS X versions, PS and a Wacom tablet, this just happens on a fairly frequent basis. No idea why, but if you download Adobe's "WhiteWindowWorkaround" plugin, it makes everything run perfectly again.
So I went from having my Mac experience virtually destroyed by Yosemite, to it running better than it ever has, with an additional 20GB of HD space to boot. Hope this helps someone.

Oct 26, 2014 10:07 PM in response to NeoNirvanaby IBRA_LBY,Hi
Thanks for the good explanation. However, I don't know how to erase my Install clean copy Yosemite on My Mac. After experiencing the bad performance, some people suggested to restore my Old 10.9 software, but I have to confess that It's frustrating to not befitted from the new Yosemite.
So Would you please explain how to format my SSD and Install Yosemite, also how to get back my old files and programs, given that I back up my laptop regularly with Time Machine. So how I get the files and programs only without the operating system.
I would be grateful if help me .

Oct 27, 2014 2:32 PM in response to IBRA_LBYby NeoNirvana,You're very welcome. For starters, you'd have to have a backup stored on an external hard drive. So make sure you're covered with Time Machine, double check it, and then I believe you restart the computer holding ctrl+shift+R, which should bring up boot settings and disk aid options. Go into Disk Utility from there, select the HD on the left (sometimes is listed as itself twice under the main left heading), and go to the Format tab (I think that's what it's called). Then pick the security option you want, anywhere from fastest/least secure all the way up to US Dept. of Defense settings. I just chose the one right after the fastest, the one that rewrites the entire disk with 0's. So do that if you want to mirror what I did. That'll take a while, when it's done and your Mac is factory fresh, brand new, you'll have the option to install Yosemite, which will RE-download it and install from there. That is a clean install. AFTER that is done and Yosemite is up and running, it'll give you the option to either set up as a new Mac or migrate data from a backup or other mac. Select the Time Machine backup and let it do its thing, and you're done.
