i turned my mac book pro off, and now it wont boot. i try reinstalling os but it wont let me.its showing it in the disk utilty,now it wont let me install.it says mac os x cannout startup from this disk.What do i do?
I can't help you until you answer the questions I asked. If you want to reinstall Snow Leopard then follow these instructions:
Downgrade Lion to Snow Leopard
1. Boot from your Snow Leopard 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.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID then click on the OK button. Click on the Partition button and wait until the process has completed.
4. Quit DU and return to the installer. Install Snow Leopard.
This will erase the whole drive so be sure to backup your files if you don't have a backup already. If you have performed a TM backup using Lion be aware that you cannot restore from that backup in Snow Leopard (see below.) I suggest you make a separate backup using Carbon Copy Cloner 3.4.1.
If you have Snow Leopard Time Machine backups, do a full system restore per #14 in Time Machine - Frequently Asked Questions. If you have subsequent backups from Lion, you can restore newer items selectively, via the "Star Wars" display, per #15 there, but be careful; some Snow Leopard apps may not work with the Lion files. -
My Mac Book Pro wont boot fully.
my MacBook pro won't boot fully. it seems to be frozen in the first page that appears (the grey one with the apple symbol). i left it there for hours to see if it was just updating. does anyone know of there's a master reset button? I'm not concerned with losing data. thanks!
Forget that software, it's of no assistance.
Read my User Tip here, especially about "Gray Screen"
https://discussions.apple.com/docs/DOC-3046
If this is all too much for you, or the Shift key on boot doesn't fix it, then perhaps consider hiring the assistance of a local PC/Mac specialist to make sure your data is recovered from both Windows and OS X.
Gray Screen issues can be quite complex to repair. It could be a simple kext file conflict (if so Shift key boot should get you in, then update all your software or check with the developers for updates)
If not it could be far worse, all depends how skilled you are with Mac's and what you have backed up etc.
If no backup, then your looking at data recovery efforts using another Mac or OS X on a external drive, no easy task.
PC/Mac specialists use a special Linux disk/USB to boot the computer and can transfer files out of either Windows or OS X.
Unfortunatly they keep it complex, so users can't use it themselves. -
I have a mac book pro with Boot Camp that also runs windows. I upgraded to Lion and now the mac side crashes/freezes periodically, especially iphoto. I am told by the genius' that I probably need to "clean" it and reinstall lion using the "recovery drive" which resets everything back to default and reinstalls the lion operating system. My question is will this also delete the "windows" partition drive and all that data too. If so that will be a huge pain in the ___ to back up and reinstall boot camp and windows. I want to shoot the lion.
There is no system like Acronis for the Mac platform. You can try using the buiilt in Disk Utility to create an Image of the complete Mac drive but I have found that this does not work very well as on tryiing to restore it gives errors sometimes.
You can use SuperDuper or Carbon Copy Cloner to create a bootable Clone of your system partition. But that is only for the System partition and not the complete drive.
If you use Boot Camp to install Windows on your Mac neither of those two programs will clone the Windows side.
Neither will Disk utility as Mac's can not create or write to a NTFS partition. So some other program is need for that. -
Mac Book Pro on boot up, the apple sign will appear with the spinning wheel. After a period of time the screen will turn grey, but the mouse will still operate, but not boot up.
If it was purchased brand new then it's running a version of Lion, so to reinstall Lion:
Reinstalling 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: Select Reinstall Lion and click on the Continue button. -
My mac book pro runs so slow and little round rainbow keep popping up
My mac book pro runs very slow and little round rainbow keeps popping up
First, back up all data immediately, as your boot drive might be failing.
Step 1
This diagnostic procedure will query the system log for messages that may indicate a hardware fault. 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|nspace-h|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. -

As it says, I got a Mac Book Pro from my company and I would like to update the apps on it. They are registered to a former employee's Apple ID, is there anyway for me to change it to my Apple ID? Or do all of the Apps need to be re-purchased?
Welcome to the Apple Support Communities
You must repurchase the applications because you can't transfer programs from an Apple ID to another one -

Also before installing Please go to Applications-->Utilities--> Adobe installers and if there is any uninstaller for CS5.5 , you can remove it and do a fresh install.
You can also use creative cloud cleaner tool before installing.
Use the CC Cleaner Tool to solve installation problems | CC, CS3-CS6

Mountain lion has killed my mac book pro. After downloading and trying to install, I am stuck in a loop of "not enough room to install on this disk" and not being able to access the old disk's data to open up space.
Nope. It just opened the installer and stayed in the same loop.
It tells me to choose a startup disk but the only option is the HD which it will not use because it says it cannot gather enough information.
Eveything was working fine until the mountain lion failed install. -

I erase my mac book pro to factory setting and cannot re-install the software. I received a message saying my Apple ID has not yet used with the App store. Please review your account information. Could anyone help please. I need to re-install my os.
Use Internet Recovery. You shouldn't need an AppleID. http://support.apple.com/kb/ht4718
Internet Recovery will install the OS that shipped with the Mac. You can then upgrade to Mavericks if that was not it.
Do you have an App Store account? Did you ever use it to install the OS?
