I am using an early 2008 MacBook Pro and am having issues with it deleting text on its own (in word, emails, etc.). As I am typing it all of a sudden starts deleting and I can't stop it. This happened once before and it was due to a buldging battery pressing on the track pad. I checked the battery and it appears to be fine. What can I do?
Please read this whole message before doing anything.
This procedure is a test, not a solution. Don’t be disappointed when you find that nothing has changed after you complete it.
Step 1
The purpose of this step is to determine whether the problem is localized to your user account.
Enable guest logins* and log in as Guest. For instructions, launch the System Preferences application, select Help from the menu bar, and enter “Set up guest users” (without the quotes) in the search box. Don't use the Safari-only “Guest User” login created by “Find My Mac.”
While logged in as Guest, you won’t have access to any of your personal files or settings. Applications will behave as if you were running them for the first time. Don’t be alarmed by this; it’s normal. If you need any passwords or other personal data in order to complete the test, memorize, print, or write them down before you begin.
Test while logged in as Guest. Same problem?
After testing, log out of the guest account and, in your own account, disable it if you wish. Any files you created in the guest account will be deleted automatically when you log out of it.
*Note: If you’ve activated “Find My Mac” or FileVault, then you can’t enable the Guest account. The “Guest User” login created by “Find My Mac” is not the same. Create a new account in which to test, and delete it, including its home folder, after testing.
Step 2
The purpose of this step is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode* and log in to the account with the problem. The instructions provided by Apple are as follows:
Shut down your computer, wait 30 seconds, and then hold down the shift key while pressing the power button.
When you see the gray Apple logo, release the shift key.
If you are prompted to log in, type your password, and then hold down the shift key again as you click Log in.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs. The next normal boot may also be somewhat slow.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
*Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t boot in safe mode.
Test while in safe mode. Same problem?
After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of steps 1 and 2. -

Trying to re-install iTunes and the message "Apple mobile device failed to start. Verify that you have sufficient privileges to start system services." But I don't know what to do? Please can someone help, I'm not the most technologically advanced person.
Go to Control Panel > Add or Remove Programs (Win XP) or Programs and Features (later)
Remove all of these items in the following order:
iTunes
Apple Software Update
Apple Mobile Device Support (if this won't uninstall move on to the next item)
Bonjour
Apple Application Support
Reboot, download iTunes, then reinstall, either using an account with administrative rights, or right-clicking the downloaded installer and selecting Run as Administrator.
The uninstall and reinstall process will preserve your iTunes library and settings, but ideally you would back up the library and your other important personal documents and data on a regular basis. See this user tip for a suggested technique.
Please note:
Some users may need to follow all the steps in whichever of the following support documents applies to their system. These include some additional manual file and folder deletions not mentioned above.

My MacBook suddenly started running slow
Hello! I've had my MacBook Pro for since 2010 and it suddenly started running slow. This has been going on for a week already. I've restarted my MacBook many times and when I'm not using it I shut it down. I've tried many things to make it run faster and deleted 14k files that were mostly text documents, pictures, videos, etc. and deleted my whole iTunes library hoping it would work but nothing. I currently have 77.07 GB left but space has never been the problem since in the past I've had 10GB or to the point where I had no GB and it still ran perfectly. Two things I've noticed is that when it gets hot it starts running slow and also when I start watching videos on youtube or ones that are already in my MacBook. Last night I reset my SMC hoping it would work better and it only ran slow because of the heat but I see no change. I'm trying anything possible to fix this myself before taking it to the Apple Store and spending money on something I could've probably fixed myself.
Here's some information on my MacBook
MacBook Pro 13-inch, Mid 2010
Processor: 2.4 GHz Intel Core 2 Duo
Graphics: NVIDIA GeForce 220M 256 MB
Software: OS X 10.8.5 (12F45)First, back up all data immediately, as your boot drive might be failing.
Step 1
This diagnostic procedure will query the log for messages that may indicate a system issue. It changes nothing, and therefore will not, in itself, solve your problem.
If you have more than one user account, these instructions must be carried out as an administrator. I've tested them only with the Safari web browser. If you use another browser, they may not work as described.
Triple-click anywhere in the line below on this page to select it:
syslog -k Sender kernel -k Message CReq 'Channel t|GPU D|I/O|find tok|n Cause: -' | tail | open -ef
Copy the selected text to the Clipboard (command-C).
Launch the 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. Click Utilities, then Terminal in the icon grid.
Paste into the Terminal window (command-V).
The command may take a noticeable amount of time to run. Wait for a new line ending in a dollar sign (“$”) to appear.
A TextEdit window will open with the output of the command. Normally the command will produce no output, and the window will be empty. If the TextEdit window (not the Terminal window) has anything in it, stop here and post it — the text, please, not a screenshot. The title of the TextEdit window doesn't matter, and you don't need to post that.
Step 2
There are a few other possible causes of generalized slow performance that you can rule out easily.
Reset the System Management Controller.
If you have a portable computer, check the cycle count of the battery. It may be due for replacement.
If you have many image or video files on the Desktop with preview icons, move them to another folder.
If applicable, uncheck all boxes in the iCloud preference pane. See whether there's any change.
Disconnect all non-essential wired peripherals and remove aftermarket expansion cards, if any.
Check your keychains in Keychain Access for excessively duplicated items.
Boot into Recovery mode, launch Disk Utility, and run Repair Disk.
If you're booting from an aftermarket SSD, see whether there's a firmware update for it.
If you have a MacBook Pro with dual graphics, disable automatic graphics switching in the Energy Saverpreference pane for better performance at the cost of shorter battery life.
Step 3
When you notice the problem, 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 4
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. If you don't see that menu, select
View ▹ Show Log List
from the menu bar.
Select the 50 or so most recent entries in the log. Copy them to the Clipboard (command-C). Paste into a reply to this message (command-V). You're looking for entries at the end of the log, not at the beginning.
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. That should be easy to do if your extract is not too long. -
My iMac suddenly started running extremely slowly. Any ideas as to what might be causing it?
My iMac has always run like a champ but it suddenly started running very slowly today. I haven't done anything different. I'm not running all kinds of programs. I've restarted several times and it takes about 20 minutes to start up. The little color wheel starts spinning every time I start to do anything and each task takes 10-20 minutes to complete. I can't do much in the way of self-diagnosis as it takes too long to do anything. I'm writing this from another computer. Any ideas of things to try before I bring it in for repairs?
Thanks.In general you should always have at least 15 - 20% of your hardd rive Free
No, this is an urban legend; you don't need 15-20% free. You should try to maintain around 30GB free, no matter what the size of your drive--and that's just a very rough ballpark; you may need much less or more, depending on how you use your computer. But you won't notice slowdowns of this order until you get really close to the edge, much lower than 30GB.
There are two possible causes for this. One, your drive is failing and you should be sure you have all your data backed up on an external before it dies completely. To check your drive get the free demo of SMART Utility. (But don't even think about doing this until you have a backup in place. That's much more important.)
http://www.volitans-software.com/smart_utility.php
The other is you may have exhausted all your available RAM and the the system is writing to the hard disk instead because nothing is left. The drive may be "thrashing" trying to accomplish this. This will make things very slow and eventually may just freeze everything up.
Open Activity Monitor in Utilities, go to the System Memory tab. How much free memory is showing? What do you see for Page ins, Page outs and Swap used? -
I upgraded to 10.0.1 on my macbook pro and now I can only open a single window -- what happened?
Since upgrading to 10.0.1 I have not been able to open more than one window in firefox. If i have a window already open going to "open" does nothing. This is extremely frustrating. I'm using a macbook pro.
I remember this happening some time ago and the fix involved setting an option somewhere ...It's been so long since I bought my macbook pro in August of 2010, but I do remember the iwork disk that had pages, numbers, and keynote on it, but I can't find the disk in my closet. I did not realize that when I took my computer in to the genius bar to upgrade to Snow Leopard, and then to download Yosemite, that I would lose these applications. I had no reason to open pages when I emptied my hard drive to upgrade to Snow Leopard, so I don't know if I kept iwork when I upgraded to Snow Leopard at the Genius Bar. I had file vault on with my external drive on, and since removed it before the upgrade, but now all my documents are unable to open on my external drive. ****. So now the new problem is how do I undo file vault in a new OS 10.10 when encoded in 6.8? Can I take my external drive in to Genius Bar?
I bought my macbook pro at Best Buy, but can't remember if iwork came with this computer, or with an older mac I bought. Can anyone check to see if I have a valid key code, and will insertion of an iwork disc allow me to use pages with Yosmite? -
Macbook suddenly started runnig slowly
A few days ago, when i was watching movie in my computer, suddenly, it started to freeze in some occasions. And i restarted my mbp, but problem was not solved. Whenever i do something in my computer, spinnig wheel starts to rotate. i read a lot of things from Support Communities but they didn't provide any help. İ tried to use it with safety mode but same things happend again(spinnig wheel rotate). i did PRAM reset etc. i almost went crazy, and i formatted mbp but the problem still going. Please help me unless i will be crazy
Here's some informations about my macbook;
13-inch, Mid 2012
Processor 2,5 GHz Intel Core i5
Memory 4 GB 1600 MHz DDR3
Graphics Intel HD Graphics 4000 1024 MB
Software OS X 10.9 (13A598)If this started happening without your having made any changes and without a warning of low disk space, then it's likely that the startup drive, or some other hardware component, is failing. Back up all data immediately, then run Apple Diagnostics or the Apple Hardware Test.
Even if the test is negative, you should make a "Genius" appointment at an Apple Store to have the machine tested more thoroughly. -
My macbook pro starts to pop after I upgraded to Mountain Lion, what can I do?
Hi guys,
As the title said, my MBP 13" late 2011 starts to have popping sound coming out from speaker a while ago.
It just pop every few minutes and I am very worried.
I did a few research and it seems like there's something to do with the hard disk.
note that this happened right after I upgraded to Mountain Lion.
comfort me!!!
Thanks for helping.Hey Samuraijin
/Hug to start with
Well when you did the upgrade the OSX ML uses your drive alot. As you said the popping sound from your research its comming form the drive. if that is the case. Check your disk with disk utitlities just incase too see if the drive is still ok. If its all Green your good if its red it might need replacement.
Note that Popping sound is usually a hardware problem or optical audio problem when using external speakers. instead of internal ones so becareful. My advice would be too be let it slide still the next patch if disk utilities says your drive is fine (Usually after 2 weeks of main realese). After that if its still there you have to get the puppy in for a checkup.
Hope i was able to comfort you in some way -
Macbook a1181 starts to power up but switches off
Starts to power up from either mains supply or battery, but always switches off after anywhere from 10 seconds to a few minutes. Chimes, usually gets as far as screen coming on etc but then you hear the power cut and it just switches off (sometimes gets as far as login screen). Any ideas? Have tried NVRAM reset SMC etc.
Reinstall Lion, Mountain Lion, or Mavericks without erasing 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
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. When the process is completed, then quit DU and return to the main menu.
Reinstall Lion, Mountain Lion, or Mavericks
OS X Mavericks- Reinstall OS X
OS X Mountain Lion- Reinstall OS X
OS X Lion- Reinstall Mac OS X
Note: You will need an active Internet connection. I suggest using Ethernet
if possible because it is three times faster than wireless. -
All of a sudden I get artifacts, freezes, kernel panics program crashes. What happening
I have a 24"imac Intel running Lion. All of a sudden I am havin all sorts of problems and I can't find a solution. I have repaired disk and permissions using install disk, done a hardware test, reinstalled Lion and restored with Time Machine, reset pram etc. Everything checks out. Disk Utility syas MacHD apprears to be fine. ***? Sorry, just out of ideas. And I'm out of Applecare. Help!
I was suggesting you run the test again. Sounds like it might the graphics chip going south. I think if you bring it in to Apple, there is no charge for diagnosis. But call ahead to confirm that. If it is the GPU, it will mean the logic board and that won't be cheap. But might not be that.

Suddenly I cannot open my scanner in PS...what happened???
Just like the title says, the Canon scanner (which works fine) will not open into Photoshop (CS2) and it has worked fine for several years. I checked with Canon and the driver is working fine. It is just something with PS. What do I do? If I uninstall and reinstall PS will I lose my photo files, etc.? Help please!

Yeah don't do a registry scan with unproven software.
After years of fighting shy of registry cleaners, I finally took the plunge and used CCleaner to get rid of a problem.
It is a very good utility. Lets you determine what is fixed, and for Registry changes, reminds you to back up the key(s) in question.
