IMac has suddenly become very slow doing everything?

My iMac has suddenly become very slow -at present it is useless and will have to take to apple unless you can help.?

First, make sure you have adequate backups. If your hard disk is failing this could be a sign. It can be replaced if necessary, but a backup strategy is recommended whether or not you are experiencing problems.
Read: OS X Mountain Lion: If your Mac runs slowly. It applies to Lion as well. The article is very cursory, but be sure to read through to the end. Unfortunately the link there is broken, so use this one: Disk Utility. To do this you must start your Mac from the Recovery System or Internet Recovery.
Rather than ask a dozen questions for more details about your system consider the following. You must be running either Lion or Mountain Lion. Including your version of OS X in your system description would help.
Apple Support Communities contributor etresoft wrote a very useful app to quickly gather certain system information that may help point to a cause of this problem. Go to his website, download and run EtreCheck:

My iMac has suddenly become very slow to wake from "sleep." Why? How can I fix this?

My iMac has suddenly become very slow to wake from "sleep." How do I fix this and what is causing the problem? Even the mouse wakes very slowly.

Try these basic troubleshooting steps.
1. Quit all app scompletely and restart the iPad. Go to the home screen first by tapping the home button. Double tap the home button and the task bar will appear with all of your recent/open apps displayed at the bottom. Tap and hold down on any app icon until it begins to wiggle. Tap the minus sign in the upper left corner of the app that you want to close. Tap the home button or anywhere above the task bar. Restart the iPad.
Restart the iPad by holding down on the sleep button until the red slider appears and then slide to shut off. To power up hold the sleep button until the Apple logo appears and let go of the button.
2. Reset the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons.
3. Go to Settings>Safari>Clear History, Cookies and Data. Restart the iPad. Restart the iPad by holding down on the sleep button until the red slider appears and then slide to shut off. To power up hold the sleep button until the Apple logo appears and let go of the button.

Need Help Ye,
boot your MacBook Pro into Recovery mode by holding down a Command key and the R key as it starts up. Once the Mac OS X Utilities menu appears, select Disk Utility. On the left-hand side of the Disk Utility window, select your internal disk’s boot partition (typically called “Macintosh HD”). On the right-hand side, press the Verify Disk button if it’s not greyed out; if it is greyed out, or if it reports that errors were found, press the Repair Disk button. Once the verification/repair is completed, exit Disk Utility and select Restart from the Apple menu to restart in normal mode. Is it still very slow?

Hello My macbook pro has suddenly become very slow,any solution?

I had no problems with my Macbook pro, since yesterday it became very slow ,i tried to close and remove many pages as possible,tried to update ,but still slow.
Any thing else to do?

Hey Tafaya,
Thanks for the question. I understand that you are experiencing performance issues with your MacBook Pro. The following resource may provide a solution, while it is titled for OS X Mavericks - the same steps apply for Yosemite:

My iMac is 6 years old. It has recently become very slow. Can I add memory? Other suggestions?

Several ways. Open a Finder window & the info will be at the very bottom of the window frame. Also, if you open Disk Utility, click your hard drive, the info will be listed in DU. If your HD is shown on your desktop, click on it. Also, the info can be found inside the System Profiler.

Aperture suddenly becomes very slow opening library

Hi.
I've got only 100 or so photos, and Aperture suddenly becomes very slow, it take a couple of minutes now to open the library.
Just before this started to happen, I got a very short massage, saying something like, "It's repairing some files."
I wonder if there are some corrupt files there, causing very slow opening the program.
Is there any way to check this and fix this problem?
I'm using 3.4.3, and OS 10.8.3.
I appreciate your help.
Hiro

I'm surprised nobody has responded to this yet. Hopefully you have already figured it out, but if you double click on the aperture library while holding down the option and command keys, Aperture will bring up a dialog that gives you three options for dealing with potential library issues: repair permissions, repair the library or rebuild the library. You should try them in that order, and it is a good idea to back up your library first (especially before rebuilding the library).
Hope this helps.

The screen on my iphone has suddenly become very sensitive and mutes ny calls all the time I know there was a bug fix but don't know how to find it?

If your screen is flickering, you might have a hardware issue there. I would take Macie to the doctor and have her checked out.

My Macbook Air has suddenly become extremely slow and is always crashing?

Hi, I would really appriciate some help right now.
I have had my Macbook Air for a little more than 2 years. It has always worked pretty well. However, recently I went on vacation for 1 week without my laptop. When I returned home and went to turn on my computer, I noticed that it had become extremely slow. Firstly, turning on my computer has become an abnormally long process. It used to take about 2-3 minutes to turn on. Now, it takes a solid 10 minutes. Not only this, but once my computer has finally turned in, it usually takes another 10 minutes before I can open an internet browser. When I click on the browser (I used Google Chrome) no window will pop up, and after a few more clicks, my screen will freeze completely. Sometimes I will get the rainbow wheel and sometimes the screen just completely freezes without it. Sometimes I will try closing the lid of my computer and then reopening it, but when I do this, the screen stays black for a long period of time even after I have reopened it, almost as if the computer is off. After an excessive amount of key smashing and an abnormally large amount of time, the screen will finally stop being in sleep mode and show my desktop. Even then, my computer will still barely work. Once I finally get a window open and start using the internet, google chrome will end up crashing within at least 20 minutes. The entire screen will freeze, I won't be able to scroll down or exit out of the window, and I then usually have to repeat the painful process that I described above when I attempt to open my broswer.
It has been over a week since I returned from vacation, and I deal with these issues every time. My computer has always been fine in the past, why is this suddenly happening?
I have tried to remove some of my applications my going into Finder and highlighting the application and clicking Move to Trash, and then emptying the trash. This hasn't helped at all. Do you think that it would help to delete some of my files and data (pictures, documents, screenshots, downloads, ect) or is this irrevevant?
I would really appricate some help! I am really sick of having to deal with this. I have no idea what is going on or how to fix it, or why this has suddenly happened after a week of being away from my computer.
Thank you so much. If you need any more detail or have any more questions, please ask.

It's likely that the internal drive is failing, or you have some other hardware fault. Make a "Genius" appointment at an Apple Store to have the machine tested.
Back up all data on the internal drive(s) before you hand over your computer to anyone. If privacy is a concern, erase the data partition(s) with the option to write zeros (do this only if you have at least two complete, independent backups, and you know how to restore to bare metal from any of them.) Don’t erase the Lion recovery partition, if present.

My macbook pro has recently become very slow

So this is the details about my macbook pro

It was running fine until the last couple months when my microsoft office started to act a bit weird. But the speed was still fine until the last few weeks.
I don't very often turn off my mac which I've read to be a problem and that it should be switched off every now and then.
I also have repaired my startup HD and also cleared my disk spaces as suggested.
I've also tried the PRAM option and the OnyX option to give the computer a clean up and maintenance.
So when i first start up the macbook pro it would run ok with most of the applications i have. I check the CPU usage and its all Ok.
The one thing that takes up all of my CPU usage % is my safari web content. When i watch something on any site or on youtube, the whole macbookpro becomes really slow as all my RAM gets used up by the safari and safari web content. I've never realised how much it is meant to use up but I dont think it is meant to use up that much.
So then after watching something on youtube and such the macbook pro becomes extremely slow and sluggish and will need a restart to run normally
Can I please have some suggestions on what is wrong and how to fix it?
Any help would be greatly appreiated!
<E-mail Edited by Host>

From the Safari menu bar, select
Safari ▹ Preferences ▹ Extensions
Turn all extensions OFF and test. If the problem is resolved, turn extensions back ON and then disable them one or a few at a time until you find the culprit.
If you wish, you may be able to salvage the errant extension by uninstalling and reinstalling it. Its settings will revert to their defaults. If the extension still causes a problem, remove it permanently or refer to its developer for support.

LR4b1 suddenly becomes very slow and multiplies "Bezel" windows

Usually it happens after lens distortions correction. Each next adjustment takes up to a minute to update. And it constantly shows and hides two additional windows called “Bezel”, one with video controls and one with a current shot info.
I have no video in catalog.
Windows7 sp1 x64, Core it-920, 12 Gb RAM
P. S. I hoped the first task for a next version would be its speed, not new functions, least of all it had to be video. It would be fine, if it was shipped as an optional plugin.

I have just downloaded LR4B1 for the first time and all Develop adjustments are very slow from outset. Opened LR3 and operation is smooth and instant.

Why has my iMac suddenly become very slow in waking up

Have not installed any new software recently but have just changed my ISP, suddenly my iMac takes nearly a minute to 'wake up' Mountain Lion installed when it first became available and it was fine after that. When it does wake up it is fine, not slow, and opens apps just as quick as before.

Hi:
As I said, there are literally thousands of messages - most relate to specific configurations.
When those messages appear, does quite a bit of time elapse?
I Googled "ACE." The only possibly relevant thing I could find is a description of Cisco networking software....

My MacBook Pro has suddenly gotten very slow. Any suggestions?

It seems to have become progressively bogged down. I've emptied TRASH and trashed DOWNLOADS. But everything is so slow.

Safari 8 has suddenly become painfully slow (Not network related)

Since yesterday, Safari has stopped working properly. Nothing has changed in my computer set up or in the applications that I use. I’m running the latest update (Version 8.0.2 (10600.2.5)) on OS X Yosemite 10.10.1 (14B25). I have a 21" mid-2011 iMac with a 2.5GHz Quad-Core i5 and 16GB of RAM.
Here are the symptoms: Safari lags like a drunk cow. It takes about 9 bounces to open after which it hogs 2 GB of RAM according to Activity Monitor—that’s with two tabs open. Webpages take upwards of 30 seconds to open. Opening a contextual menu can take 10 seconds. Opening a new tab takes 2 seconds. Everything else on the system runs smooth as butter. I’m able to edit video, sling huge files around, edit huge Photoshop documents, run processor-intensive Logic projects and browse the web (in Chrome) at lightning speed. It would therefore stand to reason that this is not a network issue or a hardware issue.
I really want to keep using Safari as it’s been my main browser for years and old habits die hard, but this is just insane. I will leave my rant about the recent nosedive in Apple’s software quality for another post as I really would like to know if there is any hope or if I should sign away my privacy to Google and live in blissful ignorance.
I’ve tried all the tricks I know: emptying the cache, clearing the history, booting in Safe Mode. Nothing helps. This is also different, on the surface at least, from the DNS Cache bug that I dealt with immediately after upgrading to Yosemite. With that bug, the progress bar would stall at 20% for 30 seconds at a time but the rest of the interface remained snappy. This is different. It's like the whole browser got dunked in molasses.

☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad and start typing the name.
The title of the Console window should be All Messages. If it isn't, select

My iMac Mid 2010 Has Suddenly Started To Slow Down.

Hello,
My iMac has suddenly started to slow down. It was fine just a week ago.. Login time has increased, Applications take a while to start and they can sometimes make my computer unresponsive.

Hello Albert, see how many of these you can answer...
See if the Disk is issuing any S.M.A.R.T errors in Disk Utility...
http://support.apple.com/kb/PH7029
Open Activity Monitor in Applications>Utilities, select All Processes & sort on CPU%, any indications there?
How much RAM & free space do you have also, click on the Memory & Disk Usage Tabs.
Open Console in Utilities & see if there are any clues or repeating messages when this happens.
In the Memory tab, are there a lot of Pageouts?

IMac has suddenly become very slow doing everything?
