does Yosemite OS hangs a lot ?

It has not hung for me on either my Mac Pro or my MacBook Pro ever.

OS 10.10.1 Hangs a LOT

I have never had this problem until now. I came back from New Years and turned my iMac on (late 2012 model, running 10.10.1) only to be extremely frustrated with hangs and freezes at odd times, such as:
1. clicking on the Apple logo in the upper left on Finder to get the menu (sometimes hangs for as long as 15 seconds or more before displaying the menu and this was after a fresh reboot with nothing else running)
2. Browsing through a folder of pictures, it takes a very long time to load the thumbnails of the photos, and also takes a long time for preview to pop up when I hit spacebar
3. Simple browsing through my Facebook News Feed via Firefox (latest version) experiences constant hangs as I scroll
4. Clicking on different emails in succession in Thunderbird (latest version) was causing a lot of unpredictable hangs
5. Going to System Preferences and trying to click through the different sections there.... hangs.
I could not get ANY work done at all and was absolutely exasperated when I searched Google for "mac os 10.10.1 hangs" and found a forum post near the top of the search results. I did as Linc Davis suggested and powered off the iMac, unplugged the cord from my uninterruptible power supply, and let it sit there for a minute or so before plugging back in, and powering on. Resetting the SMC.
This seemed to have solved SOME of the issues and the OS runs a lot better now, but I am still getting some weird issues and the occasional hang, although the hang is not lasting as long as it was previously. Whereas before, it was doing it all the time on almost every action I tried to perform, now it is doing is MUCH less but still doing it occasionally and certainly more than should be happening on such a fast computer with 16 GB ram on a fresh boot of the OS and no extra software running. This is absolutely ridiculous.
I have no idea what to do now. I'm almost afraid every time I click something.

Thank you. Here are the results from the software you recommended:
Problem description:
System is hanging a LOT on many ordinary tasks as a click around the OS and normal programs like Firefox and Thunderbird, as well as navigating Finder, etc.

My ipad is under warranty. but unfortunately it is hanging a lot. would apple replace it

my ipad is under warranty. but sometimes it is hanging a lot or sometimes if i am using some apps it closes down. will apple replace it and give me new on

Try a reset: Simultaneously hold down the Home and On buttons until the device shuts down. Ignore the off slider if it appears. Once shut down is complete, if it doesn't restart on it own, turn the device back on using the On button. In some cases it also helps to double click the Home button and close all apps BEFORE doing the reset.
Without knowing precisely what the issue is with the device, there is no way to tell if apple would replace it or not. You would need to take it in to have it checked. Based on the limited information provided, probably not. It does not sound like a hardware issue.

My iphone 5s has been hanging a lot. I bought it 15 days ago only.

I got my iphone on 19th December and since then my phone has been hanging a lot. There have been more than 4 times that the phone has frozen and restarted. My software is 7.0.4. I have deleted the apps that makes freezing to happen. It could be that they are not optimized for iOS7, but even then why would the touchscreen be unresponsive at times and a game like angry birds go hang and a game like Deer Hunter 2014 stop loading completely out of the blue moon. I have mailed the developer of Deer Hunter but I wont do that with any other app. I am using an iphone first time in my life and this is what I am getting in a welcome drink.

Search these forums for hints on how to maximize your battery life. after trying the many suggestions on these forums you still feel your battery is draining too fast Make an appointment at an Apple Store to have your device examined by a technician. Or contact Apple Support.

Does Task Scheduling use a lot of resources?

This is a curiosity question.
Instinctive I would say that task scheduling must use a lot of resources. Every fraction of a second the system must check the Task Schedule.
Does Task Scheduling use a lot of resources?

No it does not.
Windows uses task scheduling all the time without any impact on performance.
it is hard to find conceptual information on this, but it appears to me task scheduler does not check if there are possibly tasks that need to be executed each few miliseconds. Instead it sounds more logic taks scheduler waits for an interrupt to get
notified when conditions are met.
Think of it the other way around: mouse and keyboard also do not require much resources, allthough windows continuously needs to know whether a key is pressed or the mouse has moved. that is handled by interrupts. Aside of that, making a lookup (like checking
the current system time) does not use a lot of cpu time (even not miliseconds), given the fact modern cpu's do billions of operations per second (http://en.wikipedia.org/wiki/Instructions_per_second)

27" imac yosemite update hangs. Required power cycle and safe boot to get the update going. Now all OS X update do the same.

27" iMac Yosemite update hangs.
The original upgrade to Yosemite (10.10) took almost a full day! The computer hung during one of the reboots and just showed a blank grey screen, no apple logo, no progress bar, nothing. I left it like that for about an hour thinking it might be working in the dark... Eventually I had to power cycle. Disconnected power at the wall outlet for about 5 minutes, then reconnected and tried to start. After about 20 minutes, got to the same point, grey screen:no action, again waited at least an hour.
Then I did a safe boot. System came up OK in safe mode to the log in screen. As soon as I logged in, it proceeded with the interrupted update, which ran to completion. Yay!
Now, every update to Yosemite that arrives gives men the same grief!
To add some more, the "Pro Video Formats 2.0.1" update has installed about 4 times, and is asking to be installed again? There's no indication that it fails the update so whats going on?

I saw the set hibernet mode to 0 trick and it failed. Guess I can try 3 because reinstalling OS X did nothing but cost me another few hours and a little faith in Apple. Getting annoyed as I see how many people complain of the identical issue and the fixes are variable and random. Suggests to me that it is a major design flaw in the hardware and Apple got too cute with the just works idea and didn't put a damned power button on the display so there is no manual way to do it and no 'insert a pin here' type trick to reset the thing.
Asking for a refund tomorrow. Past the 14 days so maybe they'll say no but if so then every time this happens I will swap it out. At least then I know it is a three hour fix and as I was working on this for hours today it occurred to me that if the trick is to do 57 different things and maybe one will work then that is not why I made the switch to Apple. I could plug everything in on my PC and it all 'just worked'.
Really poor customer service - the support folks are very nice and I am sure they know that this is a systemic issue but aren't allowed to say so. Feeling pretty stupid for going on faith right about now.

Why does my iTunes hang every time when using automatic device detect?

Why does my iTunes hang every time that I connect either of my devices (iTouch-4th Gen, iPod Nano-5th Gen), to my Win 7 (64-bit) PC desktop? By the way, this does not happen if I open iTunes first, and then connect the device. So my workaround was to simply uncheck the checkbox that allows iTunes to start automatically upon device connection. This doesn't fix the problem, but it allows me to synch my device, but it would be nice to be able to have the autodetect work properly, so that iTunes would start normally without locking up on me and freezing. That's what I mean by 'hanging'. My whole computer doesn't freeze--only iTunes.

Hello E
Start with finding the path where the songs are on your PC by right clicking the songs that are missing in iTunes and click Get Info. You should get a window that pops up and in the Summary tab; the path will be there. Then navigate to where it was and see if the files exist. Other than that you can try to search your computer to find those files. Checkout the articles below for tips on finding the missing music, also if some of the tracks are downloaded from the iTunes Store you can download the tracks again by deleting the missing tracks from iTunes and then navigating to the purchases section in the iTunes Store to download them again.
