Is it possible to remove Yosemite? Our iMac is excruciatingly slow since its installation and I question its value

Possible to un-install Yosemite?

Thank you - am currently attempting the backup bit so unsure how/if this helps (2 hours so far)
The backup must date from before you installed Yosemite, it's too late for this method if you already installed without a backup.
You'll need to erase the disk completely to go back, so now make a backup of your files, use Time Machine.

My IMAC is operating slower since installing Yosemite?

My IMAC is operating slower since upgrading to Yosemite. I have attached the EtreCheck. Any recomendations?

First, ignore the meaningless output of that program.
Please describe the problem in as much relevant detail as possible. The "etrecheck" fad hasn't made that step any less necessary. The better your description, the better the chance of a solution.
For example, if the computer is slow, which specific actions are slow? Is it slow all the time, or only sometimes? What changes did you make, if any, just before it became slow? Have you seen any alerts or error messages? Have you done anything to try to fix it? Most importantly, do you have a current backup of all data? If the answer to the last question is "no," back up now. Ask if you need guidance. Do nothing else until you have a backup.

Since i upgraded to Yosemite, my iMac is too slow

Since i upgraded to Yosemite, my iMac is too slow. For example, at the starting up, it needs minutes 34" to open.
When i open a window / folder, i need between 1 and 2 minutes. By opening a pdf or an other document i uses 2 to 7 minutes.
WHY? How can i change this?

1. This procedure is a diagnostic test. It changes nothing, for better or worse, and therefore will not, in itself, solve the problem. But with the aid of the test results, the solution may take a few minutes, instead of hours or days.
Don't be put off by the complexity of these instructions. The process is much less complicated than the description. You do harder tasks with the computer all the time.
2. If you don't already have a current backup, back up all data before doing anything else. The backup is necessary on general principle, not because of anything in the test procedure. Backup is always a must, and when you're having any kind of trouble with the computer, you may be at higher than usual risk of losing data, whether you follow these instructions or not.
There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
3. Below are instructions to run a UNIX shell script, a type of program. As I wrote above, it changes nothing. It doesn't send or receive any data on the network. All it does is to generate a human-readable report on the state of the computer. That report goes nowhere unless you choose to share it. If you prefer, you can act on it yourself without disclosing the contents to me or anyone else.
You should be wondering whether you can believe me, and whether it's safe to run a program at the behest of a stranger. In general, no, it's not safe and I don't encourage it.
In this case, however, there are a couple of ways for you to decide whether the program is safe without having to trust me. First, you can read it. Unlike an application that you download and click to run, it's transparent, so anyone with the necessary skill can verify what it does.
You may not be able to understand the script yourself. But variations of it have been posted on this website thousands of times over a period of years. The site is hosted by Apple, which does not allow it to be used to distribute harmful software. Any one of the millions of registered users could have read the script and raised the alarm if it was harmful. Then I would not be here now and you would not be reading this message.
Nevertheless, if you can't satisfy yourself that these instructions are safe, don't follow them. Ask for other options.
4. Here's a summary of what you need to do, if you choose to proceed:
☞ Copy a line of text in this window to the Clipboard.
☞ Paste into the window of another application.
☞ Wait for the test to run. It usually takes a few minutes.
☞ Paste the results, which will have been copied automatically, back into a reply on this page.
The sequence is: copy, paste, wait, paste again. You don't need to copy a second time. Details follow.
5. You may have started the computer in "safe" mode. Preferably, these steps should be taken in “normal” mode, under the conditions in which the problem is reproduced. If the system is now in safe mode and works well enough in normal mode to run the test, restart as usual. If you can only test in safe mode, do that.
6. If you have more than one user, and the one affected by the problem is not an administrator, then please run the test twice: once while logged in as the affected user, and once as an administrator. The results may be different. The user that is created automatically on a new computer when you start it for the first time is an administrator. If you can't log in as an administrator, test as the affected user. Most personal Macs have only one user, and in that case this section doesn’t apply. Don't log in as root.
7. The script is a single long line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, though you may not see all of it in the browser window, and you can then copy it. If you try to select the line by dragging across the part you can see, you won't get all of it.
Triple-click anywhere in the line of text below on this page to select it:

Copy the selected text to the Clipboard by pressing the key combination command-C.
8. Launch the built-in Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ 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.
Click anywhere in the Terminal window and paste by pressing command-V. The text you pasted should vanish immediately. If it doesn't, press the return key.
9. If you see an error message in the Terminal window such as "Syntax error" or "Event not found," enter
exec bash
and press return. Then paste the script again.
10. If you're logged in as an administrator, you'll be prompted for your login password. Nothing will be displayed when you type it. You will not see the usual dots in place of typed characters. Make sure caps lock is off. Type carefully and then press return. You may get a one-time warning to be careful. If you make three failed attempts to enter the password, the test will run anyway, but it will produce less information. In most cases, the difference is not important. If you don't know the password, or if you prefer not to enter it, press the key combination control-C or just press return three times at the password prompt. Again, the script will still run.
If you're not logged in as an administrator, you won't be prompted for a password. The test will still run. It just won't do anything that requires administrator privileges.
11. The test may take a few minutes to run, depending on how many files you have and the speed of the computer. A computer that's abnormally slow may take longer to run the test. While it's running, there will be nothing in the Terminal window and no indication of progress. Wait for the line
[Process completed]
to appear. If you don't see it within half an hour or so, the test probably won't complete in a reasonable time. In that case, close the Terminal window and report what happened. No harm will be done.
12. When the test is complete, quit Terminal. The results will have been copied to the Clipboard automatically. They are not shown in the Terminal window. Please don't copy anything from there. All you have to do is start a reply to this comment and then paste by pressing command-V again.
At the top of the results, there will be a line that begins with the words "Start time." If you don't see that, but instead see a mass of gibberish, you didn't wait for the "Process completed" message to appear in the Terminal window. Please wait for it and try again.
If any private information, such as your name or email address, appears in the results, anonymize it before posting. Usually that won't be necessary.
13. When you post the results, you might see an error message on the web page: "You have included content in your post that is not permitted," or "You are not authorized to post." That's a bug in the forum software. Please post the test results on Pastebin, then post a link here to the page you created.
14. This is a public forum, and others may give you advice based on the results of the test. They speak only for themselves, and I don't necessarily agree with them.

My husband(less technologically inclined than I am), decided to delete programs from our iMac, he turned it off and now it has a grey screen and won't get past it. It won't start in safe mode and when I If I insert the Application Install DVD, to repair the disk, will I loose all my pictures and music?

With a corrupt disk, the install procedure is most likely going to fail.
How old it the disk?
You might be able to reformat it to fix the problem. Of course that means you lose all of your data.
The other alternative is to get a new disk drive and put that in your Mac and install OS X
Then put the old disk drive in an enclosure and see what can be recovered from it.

I want to download iBooks Author on our iMac (which has OS 10.6.8) and the download says that OS 10.7.4 or later is required. When I click to update, I'm told there are no updates available. Help?

I want to download iBooks Author on our school iMac (which has OS 10.6.8) and the download says that OS 10.7.4 or later is required. When I click to update, I'm told there are no updates available. Any suggestionss - Help?

Welcome to the Apple Support Communities
That's because OS X Lion is a paid upgrade. The most recent OS X version is Mountain Lion, so I recommend you to upgrade to this version.
First, make sure that your Mac is supported > http://www.apple.com/osx/specs If your Mac is supported, open App Store and purchase Mountain Lion. While Mountain Lion is downloading, you can make a backup of your files, so you won't lose them if the upgrade fails.
When the download finishes, the installer will show up, so follow the steps to upgrade OS X. It will upgrade OS X to 10.8.2, so you will be able to install iBooks Author and a lot of apps from the App Store. Check if your applications are supported > http://www.roaringapps.com

Uninstall Avast and CleanMyMac2.
Avast Un-install
You do not need to use cleaning programs. They can destroy your computer operation as they may already have done.
CleanMyMac - Uninstall
CleanMyMac2 Un-install
After un-installing, run this program to make sure you got all the pieces.

Does anyones iMac/macbook seem slower since upgrade to ios5 on the iphone/ipod.

When I upgraded my iphone to IOS5 my imac seemed REALLY slow. It even locked up several times. I upgraded the RAM to 4GB but that didn't hlep much. I did my kids Ipod and the same thing happened. Could it be a issue with the processes during the upgrade? How do I take care of it?

same problem here except that I can download other podcasts - have you found any solutions?

After installing Yosemite my Imac just goes to a white screen and freezes, it has been there for almost 36 hours any ideas as to why it is taking so long?

I have downloaded Yosemite from the App store and I attempted to upgrade from OS X 10.9.5. It is stuck on a white screen with a moveable mouse pointer but that is it. I can't get Command + L to work, so I can see any progress that is being made and I have tried to force boot it twice. Each time I force boot the machine I get a progress bar that goes about half way across and then just a blank white screen. I have read on some blogs that patience is the best procedure for this freeze but I have been waiting for almost 36 hours now and nothing is happening. One thing I want to mention is I have VMWare installed with a virtual machine of 300gigs, could this be the cause of the hangup? My 27inch IMAC is about 3 or 4 years old with a terabyte hard drive and 32gigs of ram. I have unplugged everything from the back except the network cable. Is about 36 hours reasonable for an upgrade? Is there a way to cut my losses and revert back to OS X 10.9.5?

When you start your notebook press F8 to enter Advanced boot options.
Is Repair my computer option available?
If yes choose it and press ENTER. Follow the menu on the screen and when you will see System recovery options try to use System Restore option.
Do you have some important data saved on your notebook?
If not install OS again using HDD recovery option and after 2 hours you will have clean preinstalled OS and everything will be OK again.

My iMac is so slow since installing Maverick. Every app takes forever to load. My Mail is horrible. I'm not sure what to do. I ran EtreCheck - if anyone can I advise, I'd be grateful.

Intel iMac 17"s slow - even after SU and firmware update

Just got 3 Intel iMacs (w/512MB RAM) to upgrade 3 users at my company, and have found basic startup (and later, opening apps) to be cripplingly slow. I have already:
Run Software Update;
Run the EFI Firmware update;
Repaired permissions;
Run Repair Disk vis "fsck -fy" from the console...
The only things I have not messed with are the USB peripherals.
Any ideas?

If you have the 17" iMacs with the 1.83 GHz chip you don't really even have 512MB of RAM. That model shares RAM with the video chip, which uses a minimum of 80 MB. Leaving only 432 MB, at most, for the Mac OS and any software you are running.
If you are seeing the spinning beachball of death you don't have enough physical RAM and the Mac is using virtual memory and constantly accessing the hard drive. You won't be happy until you have a minimum of 1 GB.
Get more RAM.

IMac starts running slow, randomly shuts off, and won't turn back on!

Last night, I was watching some YouTube videos about Swift programming and playing around on Xcode when my iMac (specs below) started to freeze between switching apps, creating files, and running my Xcode project. I tried cleaning it up using both CCleaner and OnyX. Neither of them helped. Today, I was about to run OnyX to see if it could do anything more and my iMac just shuts off. I change the outlet, still doesn't work. Go to another room and try that outlet, still doesn't work. It just sits there when I press the power button and does nothing. No sound, no startup, or anything.
• I verified my hard-drive with Disk Utility before it shut off and it said it was OK.
• I repaired permissions
• I used OnyX's verification tool to verify the hard-drive a couple different ways, every way came back clear.
iMac Specs
Software OS X 10.10.3
21.5-inch, Mid 2011
Processor 2.7 GHz Intel Core i5
Graphics AMD Radeon HD 6770M 512 MB
1 TB SATA Disk
Also there was a storm while we were gone a couple days ago, maybe a surge or something? I'm not an expert so I wouldn't know. My brother's iMac (the one I'm posting this on) works fine though.

Try running an Apple Hardware Test:

If you find you can't, make an appointment at an Apple store genius bar. The evaluation will be free and then you should know what the problems are with your MBA.
Ciao.

Imac G5 won't start white screen and flashing question mark

tried every key combo recomended - erased HD using target mode/firewire with laptop - but won't boot up from install disc...

The white screen with flashing question mark means that it cannot find a bootable volume.
The iMac G5 will not boot from just any install disk. Ideally, use the grey restore disks which came with the computer. If you've lost these, you can order them direct from Apple. Alternatively, a Mac OS X 10.5 retail install DVD will work provided the iMac G5 has also 1GB RAM (minimum requirement for 10.5).
Sometimes, if the internal drive is faulty, it can take a long time for the computer to recognise other disks. I would suggest holding down the option key on the keyboard (labled alt on some keyboards) and turning the computer on, keep holding alt until you get to the early boot menu, insert your DVD/CD, and click the circle arrow to refresh, wait a bit and the DVD/CD will show up and you can click on it to select it and boot from it by pressing the straight arrow.
After a little while it will get to the install menu, select your language, then on the next screen go through the menus to find "Disk Utility" (it's in different places on different versions of Mac OS X).
You will want to check that the internal hard drive is detected, and that it doesn't have a SMART error (it might be red, or say that the disk is failing). If you get that far, then (assuming you have erased the disk previously, as this will step really will erase the drive and take all your data with it) partition the drive, making sure that under 'Options' you select Apple Partition Map (this will be the default on earlier versions of Mac OS X, but might not be if you've erase the disk from an intel Mac like a MacBook).
Once, you done all that, and there haven't been any issues, you should be able to quit Disk Utility, and carry on with the sytem install as usual, and a 30mins to 2 hours and reboot later you should be booting from the internal drive again.

IMac i5 as slow as can be and then some

Got an i5, had it two weeks, works fine (2nd one) no worries, had a software issue, couldn't find a file to delete and so on.
So, today I decided enough was enough and to erase the drive and reinstall Snow Leopard from the Apple disc that came with the i5 30 mins later and was back to being able to use it...
BUT and it's a big but the machine is now uber slow, it's connection to the net is slow, I cant read from the cd drive very well as in it sees the discs but installing a program is almost an impossibility simply because the drive takes a while to access and so on.
Any ideas because frankly as it is it's an unusable machine and all I've done is erase and start again and as I'm typing this I'm downloading the updates (6 of) and it's taking way way much longer to download from the net.

To add to this, when attempting to copy a folder from a dvd to my hard drive I now get input/output error .....this disc and others worked perfectly before the erase and re-installation of the OS....

Imac has been slower since maverick update

wondering if anybody else is dealing with speed issues since uodate to maverick

yes mine has they said it would be faster but its slower

Is it still possible to remove pauses between tracks when ripping a CD?

In earlier versions of iTunes, it was possible to remove pauses between tracks. Many classical CDs have long sections subdivided into separate tracks, yet those sections are meant to be heard without pauses. When a CD with those separate tracks gets ripped, there is a brief pause before the next track starts. Is it still possible to remove those pauses?

Oops. I found the answer to this question after digging for about an hour.
Yes, it still can rip without pauses.
Now my issue is how to join (without pauses) music that ends on one CD and continues (without pauses) onto a second CD.
Any know of any software that does that with MP3s?

Is it possible to remove Yosemite? Our iMac is excruciatingly slow since its installation and I question its value
