Mid 2013 Mac Book Pro constantly freezing up and needing a hard restart
My mid 2012 mac book pro randomly started freezing while in use back in october. I had never had any problems with it and one night the beachball came up and nothing worked until I did a hard restart. Since then it's been happening constantly. I've had the hard drive replaced after being told that it was likely failing and the problem still remains. I've reset the Pram and everything else that can be reset. I reinstalled Lion. I've taken it to the apple store and they ran all the hardware and software test including the over night stress test for hardware and they found nothing wrong. They did a clean install at the store and the problem is still there. It is not program specific (it freezes while using any program or while doing nothing at all), it's not a ram issue. I don't have any apps except those that have come through the app store. I'm not sure what to do with it. It's basically rendered my $1300 computer unusable. Any thoughts. I'm going to try mavericks and see if that helps, have been running lion. From reading other forums it seems like this has happened to others, but it seems like everyone has different answers. Some switched to a different os, others found small hardware issues.
If it's behaving like the hard drive is bad and it's not, another likely candidate is the SATA cable which connects the drive to the motherboard. An easy way to test this is to take the drive out of the computer, move it to an external housing, and boot it from there by holding down the Option key and selecting that drive when you boot up. If everything runs fine, the SATA cable is the problem.

I need to work on Adobe Premiere on my 2013 Mac Book Pro (with thunderbolt port) and display it on my 2010 iMac (with Mini DisplayPort) using Target Display Mode (TDM). I tried using a thunderbolt cable plus Option F2, but it didn't work. Will a Mini Display cable work? Any other suggestions?

I have mid 2009 Mac Book Pro running 10.9.1. The hdmi mini port no longer supports sound on the Sony TV. This is apparently a change. It no longer shows as an option in system preferences/sound.Any ideas?
The 2009's didn't support sound on HDMI. That came in 2010. Are you sure it ever worked?

f i have a mid 2009 mac book pro and an apple tv that is the latest one. i can not mirror the mac book on my tv. is it the fact that my computer is a little older than 2011 models which will work. any info is greatly appreciated
chuck schickYes. You need 2011 or later in order to mirror as it requires the newer processor. The alternative is airparrot, which does it via software.

I would open Activity Monitor (Utilities folder) to check and see if there is something using an inordinate amount of CPU cycles......select the CPU tab and click on the drop down menu from the top of that window.....choose (All Processes's).......double or triple %'s....will ramp up the fan...

I've been to Genius twice, rebuilt OS X Yosemite, had the motherboard replaced and some other components, but my 2013 mac book pro continues to crash inside Safari. I removed all extensions and add-ons and my computer still panics and crashes in Safari. Finally, I moved on to Firefox and behold, no more crashes. Just thought others would like know that Apple has its work cut out for them and possibly moving on to a different browser is a better solution.

Do not resize your hard drive in Windows with Disk Management or you will probably damage the partition table. Apple has designed a hybrid partition table so OS X detects it as GPT and Windows detects it as MBR, so now you have converted the hard drive into a dynamic partition table and you cannot start up in OS X or Windows.
See if you can use OS X Recovery. To do it, hold Command and R keys while your Mac is starting up, and try to reinstall OS X. However, this will not let you erase the hard drive, so you probably have to take the Mac to an Apple Store or reseller to get your Mac working again -
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 -

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? -
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.
