Tried uninstalling, now my MacBook is slow.
About a week ago I tried to install Windows 7 on my 2011 MacBook Pro. The install didn't work, though it showed as having completed (booting windows just got me a black screen with an "error, press any key to boot from disc" message). When I tried to uninstall it, the option in Boot Camp Assistant to uninstall was greyed out and I couldn't find any way to get rid of it. So eventually I just deleted the partition that contained Windows 7. Everything was fine until yesterday when my computer took 20 min to startup, all apps were extremely sluggish, performing one operation in one app caused all other apps to freeze for at least a minute, and closing anything required a force quit. I checked disc utility, and while the windows partition had been deleted, the main partition hadn't expanded to take over the old partition.
I just wanted to see if anyone knew of any solutions to this issue, or if I'd have to resort to backing up my data and doing a fresh OSX install. Thanks.
See this FAQ on tuning OS X for better performance.
If you only have 2GB of memory, and the problem started with Lion/Mountain Lion, upgrade to 4GB (this is a common problem).

Groovorio penetrated my computer, has burrowed in. When I try to call Firefox, Groovorio appears instead.
I tried the Uninstall command in Control Panel, Programs and Features. Now, the name Groovorio has disappeared from the list of programs, but it continues to replace FIrefox.
I wish to get rid of Groovorio.com and to get my Firefox setup back to where it was before Sept. 25.
This may be relevant: I first noticed Groovorio soon after I installed "iLivid", which was presented as necessary to optimize communications with a college course website.

Just updated from 10.6.8 to 10.9, now my 3 year old Macbook is slow.
I just downloaded the new Mavericks 10.9 OS X (after 13 hours) and now my Macbook (purchased brand new in 2010) is super slow. I'm having delayed click-to-open responses and load time is ridculous. iMovie is THE WORST!! It took me 2 hours to put together a 2 minute video.
What I've tried:
Restarting
Updating EVERYTHING
Getting rid of apps I don't use/need
Resetting the PRAM
Downloaded and ran 'Clean Memory', which did not help
Ran Activiy Monitor (Kernal Task uses the most, wich flucuates from 2.4-19.6, but everything else flucuates from 0.0-4.2)
What I don't understand is that all the research (for the last 3 hours) I've done, says that I must not have anough memory/storage. But this is not the case, considering I have 249.2 used and 115.1 free.
I'm at my wits end and I want this fixed. My life is on the computer and I need it. Please, any suggestions would be helpful.Remove Clean Memory from your Mac. It's not necesary and may be causing part of the problem.

I downloded some update for the Itunes, and now my Macbook Pro its toooooo slow, I dont know what do to anymore. I even reinstalled the whole system. Can anybody help me???
Do the following. There's nothing of interest in the Activity Monitor data.
Things You Can Do To Resolve Slow Downs
If your computer seems to be running slower here are some things you can do:
Start with a visit to: OS X Maintenance - MacAttorney.
Boot into Safe Mode then repair your hard drive and permissions:
Repair the Hard Drive and Permissions Pre-Lion
Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. 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 installer.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
Repair the Hard Drive - Lion
Boot from your Lion Recovery HD. 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, then click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu. Select Restart from the Apple menu.
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.
Restart your computer normally and see if this has helped any. Next do some maintenance:
Suggestions for OS X Maintenance
For situations Disk Utility cannot handle the best third-party utility is Disk Warrior; DW only fixes problems with the disk directory, but most disk problems are caused by directory corruption; Disk Warrior 4.x is now Intel Mac compatible.
OS X performs certain maintenance functions that are scheduled to occur on a daily, weekly, or monthly period. The maintenance scripts run in the early AM only if the computer is turned on 24/7 (no sleep.) If this isn't the case, then an excellent solution is to download and install a shareware utility such asMacaroni, JAW PseudoAnacron, or Anacron that will automate the maintenance activity regardless of whether the computer is turned off or asleep. Dependence upon third-party utilities to run the periodic maintenance scripts was significantly reduced since Tiger. These utilities have limited or no functionality with Snow Leopard or Lion and should not be installed.
OS X automatically defragments files less than 20 MBs in size, so unless you have a disk full of very large files there's little need for defragmenting the hard drive. As for virus protection there are few if any such animals affecting OS X. You can protect the computer easily using the freeware Open Source virus protection software ClamXAV. Personally I would avoid most commercial anti-virus software because of their potential for causing problems. For more about malware see Macintosh Virus Guide.
I would also recommend downloading a utility such as TinkerTool System, OnyX 2.4.3, or Cocktail 5.1.1that you can use for periodic maintenance such as removing old log files and archives, clearing caches, etc.
For emergency repairs install the freeware utility Applejack. If you cannot start up in OS X, you may be able to start in single-user mode from which you can run Applejack to do a whole set of repair and maintenance routines from the command line. Note that AppleJack 1.5 is required for Leopard. AppleJack 1.6 is compatible with Snow Leopard. There is no confirmation that this version also works with Lion.
When you install any new system software or updates be sure to repair the hard drive and permissions beforehand.
Get an external Firewire drive at least equal in size to the internal hard drive and make (and maintain) a bootable clone/backup. You can make a bootable clone using the Restore option of Disk Utility. You can also make and maintain clones with good backup software. My personal recommendations are (order is not significant):
1. Carbon Copy Cloner
2. Data Backup
3. Deja Vu
4. SuperDuper!
5. SyncTwoFolders
6. Synk Pro
7. Synk Standard
8. Tri-Backup
Visit The XLab FAQs and read the FAQs on maintenance, optimization, virus protection, and backup and restore.
Additional suggestions will be found in Mac maintenance Quick Assist.
Referenced software can be found at CNet Downloads or MacUpdate.
Additional Hints
Be sure you have an adequate amount of RAM installed for the number of applications you run concurrently. Be sure you leave a minimum of 10% of the hard drive's capacity as free space.
Add more RAM. If your computer has less than 2 GBs of RAM and you are using OS X Leopard or later, then you can do with more RAM. Snow Leopard and Lion work much better with 4 GBs of RAM than their system minimums. The more concurrent applications you tend to use the more RAM you should have.
Always maintain at least 15 GBs or 10% of your hard drive's capacity as free space, whichever is greater. OS X is frequently accessing your hard drive, so providing adequate free space will keep things from slowing down.
Check for applications that may be hogging the CPU:
Open Activity Monitor in the Utilities folder. Select All Processes from the Processes dropdown menu. Click twice on the CPU% column header to display in descending order. If you find a process using a large amount of CPU time, then select the process and click on the Quit icon in the toolbar. Click on the Force Quit button to kill the process. See if that helps. Be sure to note the name of the runaway process so you can track down the cause of the problem.
Often this problem occurs because of a corrupted cache or preferences file or an attempt to write to a corrupted log file.
If none of the above help, and they may not, then this should:
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. -
Our old macbook was getting a gray screen with flashing ? on bootup. Eventually I restored it using Time Machine then decided to reinstall Snow Leopard since it would not boot. Machine now boots but is slow. Ran repair disc and tried to run repair disc permissions but got a message that it was cancelled by user.
This machine is at least 6 years old and I just want to limp it along until I can afford to replace it in the spring.You may be smelling it because with the new OS the processor is having to work harder causing it to get hotter then it would with the other OS. I can't say there is nothing wrong, but what could be happening is just that, it's getting hotter so the fan is spinning faster and moving more air so you are getting more of the smell then you would before. I would still continue to back it up, and take it to the Apple Store at a Genius Bar and have them look at it to make sure. Was the computer ever in a smoky environment??

What? so were you able to turn on the computer with the new plug? does it give you any other light? amber/orange light? -
Wiped our old iPad 1 clean, now can't install iOS from iTunes using laptop PC (W Vista). iTunes does not "see" the device. Tried uninstalling and installing iTunes on laptop. Also bought new USB cable. The iPad is charging, but that's all it does. Just want to get it operating again for browsing and e-reading.
OK. You merely erased the content and settings. The IOS is still there.
If it has NEVER been jailbroke, here are some standard repair procedures. From what you've already stated, my guess is that you'll end up with Recovery Mode described in the last paragraph.
First, try a system reset. It cures many ills and it's quick, easy and harmless...
Hold down the on/off switch and the Home button simultaneously until you see the Apple logo. Ignore the "Slide to power off" text if it appears. You will not lose any apps, data, music, movies, settings, etc.
If the Reset doesn't work, try a Restore. Note that it's nowhere near as quick as a Reset. It could take well over an hour! Connect via cable to the computer that you use for sync. From iTunes, select the iPad/iPod and then select the Summary tab. Follow the on-screen directions for Restore and be sure to say "yes" to the backup. You will be warned that all data (apps, music, movies, etc.) will be erased but, as the Restore finishes, you will be asked if you wish the contents of the backup to be copied to the iPad/iPod. Again, say "yes."
At the end of the basic Restore, you will be asked if you wish to sync the iPad/iPod. As before, say "yes." Note that that sync selection will disappear and the Restore will end if you do not respond within a reasonable time. If that happens, only the apps that are part of the IOS will appear on your device. Corrective action is simple - choose manual "Sync" from the bottom right of iTunes.
If you're unable to do the Restore (or it doesn't help), go into Recovery Mode per the instructions here. You WILL lose all of your data (game scores, etc,) but, for the most part, you can redownload apps and music without being charged again. Also, read this. -

I tried to copy too much to desktop and now my MacBook pro is frozen!
I tried to copy way too many items to my desktop, and now my MacBook is running at a snails pace. It is essentially frozen. It always has the rainbow cursor, sometimes it's spinning sometimes not. I have restarted in safe mode, and has not really helped. If I try to do anything by clicking on it it, It doesn't respond usually at all, and if it does it takes about 20 minutes. What can I do?

ThanksHow did you accidentally erase the drive? You can only do that be booting from your Recovery HD or another hard drive.
Are you connected to the Internet? Be sure you can run an Ethernet cable from the computer to your router as this will be much faster than wireless.

My IMac is so slow after having to do a hard restart. I have BitDefender 2011 for Mac and it was running a scan when I tried logging into my online banking. At the same time, I accidentally hit "update" on the Bitdefender icon to update the latest virus and malware definitions. Now my iMac is slow and useless. I have iOS5 and the latest Snow Leopard. Help please!
Before we get too far, please clarify this part:
I have a 2009 iMac 4,1
A 2009 iMac cannot be an iMac 4,1; they are 9,1 and higher. Did you mean to type "2006?" That would be an iMac 4,1. We need to pin down the model issue before proceeding.
It could be the drive, not the disk, that is dirty. Try a drive cleaning disk, usually about US$5-15 at home entertainment, electronics stores and office superstores -
I cannot use iTunes anymore. My computer becomes extremely slow or just freezes. I notice the problem started after I updated iTunes to a new version. I have tried uninstalling iTunes completely from my computer and installing it back, but problem continues. We iTunes launches, it tries to connect to iTunes store, but it doesn't seem to be able to do that either. I can't sync my iPod or play back my music, please help.
With those symptoms, I'd try the following document:

Follow Troubleshooting security software. Often, uninstalling third-party security software will resolve these errors.
There may be third-party software that modifies your default packet size in Windows by inserting a TcpWindowSize entry into your registry. Your default packet size being set incorrectly can cause these errors. Contact the manufacturer of the software that installed the packet size modification for assistance or follow this article by Microsoft: How to reset Internet Protocol (TCP/IP).
Verify that access to ports 80 and 443 are allowed on your network.
Verify that communication to albert.apple.com or photos.apple.com is not blocked by a firewall, or other Internet security setting.
Discard the .ipsw file, open iTunes and attempt to download the update again. See the steps underAdvanced Steps > Rename, move, or delete the iOS software file (.ipsw) below for file locations.

I updated my Itunes the other day and now, when clicking on the itunes icon, the program does not open?? I have tried uninstalling and reinstalling, resetting the computer, checking permissions, running as adminstrator.. nothing is working?? Help!!
Amazing steps you've done so far! The great news is this is very unlikely an issue with your iPhone.
I've run into a similar issue lately as well. I narrowed it down to one song that was causing 30 songs not to sync. I removed the song from the sync list (unchecked it) and all 29 songs were able to sync.
You may be running into a similar issue. This may be a problem with this version of iTunes, an issue with one song or a group of songs; hard to know for sure. It's important to narrow down and isolate the cause. Most imporantly get that music back on there!
The way to narrow down the casue add just a few songs at a time (even 1, just to get that first sync finished). Manually syncing is what you'll need here.
Plug in your iPhone, on the Summary screen (shows a picture of your iPhone, the iOS version, Restore iPhone....; etc). Under the Options area at the bottom choose to Manually Manage Videos and Music then choose Apply in the lower right. The music that's on your iPhone now should be removed from your iPhone now. You're now able to sync music manually.
The link below explains how to drag the songs from the iTunes library on the computer on to your iPhone which will start the sync. Add just one song just to see if you can get 1 of those hundreds of songs on there. If you can, awesome! Keep adding until you find the song or group of songs that are causing this issue.
