My Mac is running super slow after upgrading to Mountain Lion....Help!

I'm really not very good with computers so I may need a bit more basic help

First, back up all data immediately, as your boot drive might be failing.
One possible cause of a slow user interface is a large number of image or video files on the Desktop with preview icons. If you have more than a dozen or so such files, move them to another folder.
Otherwise, take these steps when you notice the slowdown.
Step 1
Launch the Activity Monitor 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. Click Utilities, then Activity Monitor in the icon grid.
Select the CPU tab of the Activity Monitor window.
Select All Processes from the menu in the toolbar, if not already selected.
Click the heading of the % CPU column in the process table to sort the entries by CPU usage. You may have to click it twice to get the highest value at the top. What is it, and what is the process? Also post the values for % User, % System, and % Idle at the bottom of the window.
Select the System Memory tab. What values are shown in the bottom part of the window for Page outs and Swap used?
Next, select the Disk Activity tab. Post the approximate values shown for Reads in/sec and Writes out/sec (not Reads in and Writes out.)
Step 2
If you have more than one user account, you must be logged in as an administrator to carry out this step.
Launch the Console application in the same way you launched Activity Monitor. Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left.
Select the 50 or so most recent messages in the log. Copy them (command-C) to the Clipboard. Paste (command-V) into a reply to this message.
When posting a log extract, be selective. Don't post more than is requested.
Please do not indiscriminately dump thousands of lines from the log into this discussion.
Important: Some personal information, such as your name, may appear in the log. Anonymize before posting.

My iMac is running extremely slow after upgrading to mountain lion

Ever since upgrading my OS, my computer is running extremely slow. Any tips to improve performance?

How much RAM is your system running? Do a Disk Repair and see if that resolves any issues.

Why has my Safari and MAIL slowed after upgrading to Mountain Lion on my MacBookPro ?

Why has my Safari and MAIL slowed after upgrading to Mountain Lion ? I have mid-2009 MBPro and have very fast Internet access router.

I have noticed the same thing on my MAC. Mail has become very "clunky"- Before Mountain Lion, whenever I clicked on a msg or a function (delete), it would respond immediately. With Mountain Lion there is an unacceptable hesitation. What is going on with this latest update?

MacPro usb very slow after upgrading to mountain lion

When backing up with Carbon Copy to an external USB drive very slow, eventually the system freezes. After upgrading to Mountain Lion its been a complete pain when trying to do back-ups. Does Apple have a USB software fix for this?

Disconnect the external drive and see whether there's an improvement.

IPhone running super slow after upgrading to SO5

i took it to the apple store and they told me to back up everything and then try restoring. I did, and has made no difference. all apps run SUPER slow. safari is SUPER slow. so frustrated.

Did you try a Restore as New...
Backup and Set Up as New Device
http://support.apple.com/kb/HT4137
Try this First... You will Not Lose Any Data...
Turn the Phone Off... ( if it isn’t already )
Press and Hold the Sleep/Wake Button and the Home Button at the Same Time...
Wait for the Apple logo to Appear and then Disappear...
Usually takes about 15 - 20 Seconds... (But can take Longer...)
Release the Buttons...
Turn the Phone On...

My 2011 Macbook has become exceedingly slow after upgrading to Mountain Lion.

I have a 2011 Macbook which has become really slow after I upgraded to Mountain Lion in March. At first it wasn't that bad, but it's getting worse and my computer has begun to overheat even if I'm only using Google Chrome. I used to be able to keep multiple applications open at once and never closed many of them, but now if I want to get anything done I have to use the absolute minimum. My CPU has reached 86 degrees Celsius and temperatures slightly below this seem to be the average, even if I've only been on for ten minutes. It heats up VERY quickly. The fan has been operating at 2919 rpm, but it has said that for days and I don't know if this number should be changing? (I know that normal is about 2000 rpm, so I know it shouldn't be that high anyway.)
I'm currently working on cleaning out my harddrive of duplicate and unnecessary files and I plan on restoring to the default settings and backing everything up on an external harddrive... but are there other things I should be doing to speed my computer back up, like good programs to clean out my computer's temporary memory on a regular basis? The problem seems to have come on pretty fast though, so I don't know if there could be something else wrong with it and if I should take it into an Apple-approved repair place.
Also, I'm not one to illegally download/pirate things from sketchy websites, so I highly doubt a virus is the cause, especially given that Macs rarely get viruses.
Any suggestions of what to do and what programs/apps to install would be greatly appreciated! Thank you!

ICal Events on my mac not showing in reminders after upgrading to mountain lion

after upgrading to mountin lion, all calenders on my mac are not showing in the reminders app, only calenders on icloud. The irony is all calenders created on my mac have been reclassified on iCloud. This was done automatically during the last upgrade and I chose to have my calenders on iCloud, so now they are listed twice in the iCal, however, there seems to be a difference between entries. For instance if I turn off the work calender on my mac, different things are removed than if I turn of the work calender on iCloud - i don't understand how or why this happens. In Reminders those very same calenders that are listed as iCloud on the iCal are listed as "on my mac" in the Reminder app and do not show anything. The only calenders on the Reminders app that appear under "iCloud" are the ones that I created on my iPhone. All these calenders are showing the correct entries.
SO far not terribly impressed with Mountian Lion. I am also annoyed that it seems that I can no longer view all my entries from calender tasks at the same time like I used to be able to with Lion. This was very useful. It is now terribly inconvenient to have to check each calender and list in turn (I have nine) to be reminded, unlike in Lion with the list just to the side of iCal.
Any help with the above problem?

In the mailbox panel move your cursor slowly down the right hand side . Should reveal show and hide.

Any ideas how to solve?

You can go into the OS X Server Forum and search for this issue. I think there are some discussiom threads that discuss it and you can read some of the solutions.
I'm also running Mountain Lion 10.8.2 and OS X Server on a Mac Mini and it won't sleep if I have the File Sharing, VPN and Printer Sharing services running. To me, this is a good thing as a server is usually available to client machines 24x7.
I did experiment and turned off each service one at a time to see which ones deny the sleep function and I found all 3 do.
Here's an example from my server. The bold entries are the culprits for my server.

MacBook Pro slower after upgrading to mountain lion?

MacBook Pro 2009
Factory setting: Snow Leopard
Just 2 days ago, I reformatted my macbook back to its factory settings. Processing speed was fast and opening of apps does not seem to lag. Booting up and shutting down only took seconds. After reformatting my macbook, I upgraded my iOS from snow leopard to mountain lion and that is where the problems arises.
1. Booting up and shutting takes much longer time? It used to be less than 10 seconds however, now it takes about 40-50 seconds.
2. Opening of apps seemed to be slower. Example: When I open my iTunes, the app will bounce a few times and takes a few seconds (longer than before) for the app to appear.
3. Whenever I try to select something when surfing net or doing some other programs, the mouse cursor will never fail to change to the "colourful ball" which I will have to wait for it to load.
Can anyone help here?

Reinstalling Lion/Mountain Lion Without Erasing the Drive
Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu.
Reinstall Lion/Mountain Lion: Select Reinstall Lion/Mountain Lion and click on the Continue button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.

My macbook pro is running really slow after upgrade to Mavericks

my macbook pro is running really slow after upgrading to Mavericks....any ideas?

OS X Mavericks: If your Mac runs slowly
The above link is not very useful, so if it doesn't help read on.
There are many potential reasons that a Mac may be running slower than expected, but more information is required to begin troubleshooting, much more.
Back up your documents and everything else important to you before proceeding. It is premature to conclude your hard disk is failing, but the symptoms you describe may presage an impending disk failure, and you should have backups anyway.
To help determine the possible causes of this behaviour read the following. None of what follows is intended to fix anything, but it will provide the additional information required to advance troubleshooting:
Boot OS X Recovery by holding ⌘ and r (two fingers) while you start your Mac. At the Mac OS X Utilities screen, select Disk Utility. Select your startup volume (usually named "Macintosh HD") and click the Repair Disk button. Describe any errors it reports in red.
When it finishes restart your Mac and test again for operation. If it's still not behaving as you expect it should, please post the results of EtreCheck in accordance with the following instructions:
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:
http://www.etresoft.com/etrecheck
Etrecheck will be in your Downloads folder. Open it from there. You may see the following dialog box:
Click Open - etresoft contributes to this forum frequently and can be considered a trustworthy developer.
It will take a moment to run as it collects its data.
Copy and paste its output in a reply.
Do not be concerned about anything that says "Problem" or “failed” or anything else that may appear in red.
EtreCheck was designed to remove any personal information (such as your computer's name and serial numbers) but if you see anything that looks like an email address or any other personal information that should not be divulged to others, please delete or obscure that information when you post the reply.
When you are finished with EtreCheck, quit the program. It occupies very little space, and you can keep it or drag it to the Trash as you wish.
After completing the above please determine if the problems also occur in "Safe Mode":
Safe Mode or "Safe Boot" is a troubleshooting mode that bypasses all third party system extensions and loads only required system components. Read about it: Starting up in Safe Mode
You must disable FileVault before you can start your Mac in Safe Mode.
Starting your Mac in Safe Mode will take longer than usual, graphics will not render smoothly, audio is disabled on some Macs, and some programs (iTunes for example) may not work at all.
Merely starting your Mac in Safe Mode is not intended to resolve the problem, it's to observe its performance without certain additional components.
To end Safe Mode restart your Mac normally. Shutdown will take longer as well.
System performance problems for reasons that cannot be isolated to any other cause justify an SMC reset. Be sure to read the procedure carefully and follow all the steps exactly as written, even if they seem inapplicable or trivial.

Macbook pro running super slow after downloading Lion

My mac book pro is running super slow after downloading Lion. Its so slow and all I see is the beach ball wait icon. Also my safari and firefox internet apps crash like crazy. What can I do? Hate it!

Hi,
I also have this problem. My MacBook pro was brand new in august, but i bought it just a few days before the release of lion so i installed lion after i bought it. Only used it 1 day with whatever was on it before and seemed to work fine.
Ive been too busy to do anything about it but im very annoyed by how slow it is so i have to do something now, what can I do? can someone help with some specific steps? someone posted something about changing the network settings but I wasnt sure if that applied in europe (spain)... any guideance in non-technical terms please?
THANK YOUUU

After upgrading to mountain lion my mac is very slow?

Hello
After upgrading to mountain lion my mac is very slow
It was starting in 10 seconds and shuting dow in 5 seconds and now it's taking more than one minute to start it or shut down it and everything is slow
why????????/
Thanks

First, back up all data immediately, as your boot drive might be failing.
Take these steps when you notice the problem.
Step 1
Launch the Activity Monitor 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. Click Utilities, then Activity Monitor in the icon grid.
Select the CPU tab of the Activity Monitor window.
Select All Processes from the menu in the toolbar, if not already selected.
Click the heading of the % CPU column in the process table to sort the entries by CPU usage. You may have to click it twice to get the highest value at the top. What is it, and what is the process? Also post the values for % User, % System, and % Idle at the bottom of the window.
Select the System Memory tab. What values are shown in the bottom part of the window for Page outs and Swap used?
Next, select the Disk Activity tab. Post the approximate values shown for Reads in/sec and Writes out/sec (not Reads in and Writes out.)
Step 2
You must be logged in as an administrator to carry out this step.
Launch the Console application in the same way as above. Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left.
Post the 50 or so most recent messages in the log — the text, please, not a screenshot.

After upgrading to Mountain Lion on my 2011 27" iMac, my Mac occasionally lock-ups.

After upgrading to Mountain Lion on my 2011 27" iMac, my Mac occassionaly locks up while using Safari, Mail or Dreamweaver and I have to d a force-quit, then restart my Mac. Anybody having similar probelms?
I am thinking about doing a clean install of Mountain Lion. Would I be able to restore my applications and data from Time Machine after the re-install?

My 24 inch iMac... 2.8 GHZ dual core (Early 2008) is having the same problem. After it sleeps, I go to use something... and the beachball of death occurs. This happens multiple times a day... and let me tell you... it is annoying... and I am the one who is being annoyed!
It could possibly be revolving around safari... as that is really the only thing that is running consistently. I don't use iTunes on this iMac as I have so many other Macs up and running in the house... and I never consume media on it... so I kind of dismiss iTunes being the culprit.
This is majorly affecting my Mac... in terms of reliability and uptime... which coincedently is the main reason why I switched to Mac in 2008. This is my only Mac that could upgrade to ML... so I don't know how widespread this is... but I hope that this problem can be solved...
I agree with another person who commented on this issue... do we really need a 10.8.1 update already... to fix this?

My Mac is running super slow after upgrading to Mountain Lion....Help!
