Try monitoring the temperature so you know for sure. Yes it can run hot.

You may want to boot from your original OS X DVD - hold D on statup - and that way run Apple Hardware Test

You won't be able to change your rescue email address until you can answer 2 of your questions, you will need to contact iTunes Support / Apple to get the questions reset.
Contacting Apple about account security : http://support.apple.com/kb/HT5699
When they've been reset you can then use the steps half-way down this page to update your rescue email address for potential future use : http://support.apple.com/kb/HT5312

Open your Displays system preferences. Is there an Arrangement tab and does it show two screens? If no Arrangement tab then your mac does not know it has two screens. Maybe smc and pram reset will shake it free and maybe not. Maybe there's something wrong with the connection. Thunderbolt plugs are similar to mini-displayport plugs so make sure the plug is pushed firmly in so that essentially all the metal part disappears inside the socket. The plugs can be a little tricky in that you need to make sure the plug is fully seated in their socket.
If you do see two screens in the Arrangement tab then click Detect Displays and Gather Windows to get the Displays preferences of the other monitor on to your main monitor. Check the resolution and if there is a refresh rate check that as well.

I recently received a mac book air 11 inch for christmas ... i beliehve it was bought in the states from my father i was unaware of the specs until i opened and read it... and i was wondering if i can still do the upgrade to 8gb ram and bigger flash drive

i recently received a mac book air 11 inch for christmas ... i beliehve it was bought in the states from my father i was unaware of the specs until i opened and read it... and i was wondering if i can still do the upgrade to 8gb ram and bigger flash drive.. is this possible and for how much? its only a week old.

Your 14 days are up, however you could take your case to Apple Inc. regarding same,
however those are the stipulations.
RAM cannot be upgraded however, period, its permanent on the logic board after mfg.
As for the SSD (solid state drive), upgrading same is a bad premise 9 times out of 10.
No notebooks is a mass storage device, and you need an external HD for data redundancy and backups regardless.
data that is static on your SSD and not used very often has no logical reason to be ON the notebooks, and best saved on a superslim external HD ($60)
SSD are very expensive, even a small one, HD are cheap as dirt and users are recommended to have one regardless for many good reasons.

HT1338 The screen on My mac book pro goes black for no reason if I use the f1 and f2 keys it comes back

My screen on my mac book pro goes blank for no reason when I use f1 and f2 keys it comes back

You can blank the monitor using those keys, that's likely what you did, it's a feature.

Ever since I updated to Yosemite my mac book pro keeps asking for Apple Id and password but will not accept them

Ever since I updated to Yosemite my mac book pro keeps asking for Apple Id and password but will not accept them. What can I do?

Try the advice here. I had the same problem and it worked for me.
You have to delete the "SC Info" folder from /Users/Shared. You will have to use Terminal to enable you to see this folder first. Make sure iTunes is not running when you delete the "SC Info" folder
There is an article from Apple on this here. The "SC Info" folder contains iTunes authorization information.
I did this two weeks ago and iTunes accepted by login. I haven't been asked for my AppleID or password since.

Copa there is a option for reset value field / quantity value filed

Hi
As per the sap standard in copa there is a option for reset value field / quantity value filed. We
use this function to reset a quantity or value field depending on the
billing type (For eg L2 (Debit Memo) G2(Credit Memo). This means that
the condition value set in the field is replaced by value 0. Due to
this quantity value filed in copa reflects nil. My client requirement is when profit center document is generated System should display the quantity as nil.
i have tried some enhancement but these enhancement is only used in case of PGI . But in the case of debit and credit memo their is no PGI. first we create debit not request (va01) then billing(vf01) then document is generated .
Can we do the same thing in profit center Accounting? When PCA document
is generated System should display the quantity as nil.
Please let me know some user exit or substitution or Bte we can use ?
Anjali

hi Jerry,
Very appreciated the link you sent. In this article of this link, it gives an example of a conversion from an external to an internal format:
1. '1234 ' -> '00001234'
2. 'ABCD ' -> 'ABCD '
Just wonder why the external format '1234 ' has to be converted to '00001234', what's the purpose of doing this converstion?
Thanks!

Help! I need a recommedation for a Mac Book Pro or Air for a singer-songwriter who needs to burn CDs and makes 30 minute to hour-long recordings. Thanks!

I am a hypnotherapist and singer-songwriter who purchased Pro Tools and took a brief class, but I'm not an engineer and it is over my head. I am looking at purchasing a Mac Book Pro or Air to dumb down to a Garageband app in order to keep production moving while I learn Pro Tools.
Can anyone recommend which laptop to get? I now have a Dell Studio XPS with Pro Tools on it. Just need to keep my clients happy,and I make recordings that are 30 minutes to an hour long for them, then burn CD's and/or make mp3s that I email to them.
Any help would be greatly appreciated!! Many thanks!

BTW (speaking as a Dad of 3 daughters in Grad school) if you don't already have and use a DropBox account, or some other similar online "cloud" based backup of your school documents, you should start doing so immediately. By keeping all of your important documents in the Dropbox folder on your computer, you have instant access to them from any other computer (or iPad), should you be w/o your computer while in for repairs (or if, God forbid, it is stolen). It's free for 2 GB of online storage, which is more than enough for a few years worth of Word documents, etc. (If you get other people to sign up via your email "invitation", then Dropbox gives you even more free storage space.) Every time you close a document, it is updated on the Dropbox servers (encrypted), if it is in the Dropbox folder (assuming you give it a few seconds to update before turning off your computer). Do a google search of "Cloud based storage comparisons" to compare the amount of free space each of the competing services give you.

If you can' get to Apple, read on.....
You are probably experiencing a Kernel Panic as seen and described in Apple doc. HT1392. If not, disregard.
Bad or incompatible RAM is, more often then not, the cause of most Kernel Panics. It could also just need to be reset.
Here's the most used site for Resolving Kernel Panics. Please do all the steps in order, even if you don't think you need to do a certain step.
Here is a great MacFixIt article.

Need help picking Mac Book specifications for FCP

Okay. . .dumb beginners question here:
Which MacBook and how should it be configured would you order to run latest version of FCP?
I'm ready to order one and to order FCP.
TIA
Pending Pending

agreed. a MacBook Pro is what you will need if you wish to take full advantage of all the software in the FCS1 bundle, even more so for FCS2.
My preference is for the 17". Although obviously larger and heavier, it has the screen real estate that you need for the Pro apps.
Internal hard disc, bigger but slower or smaller and faster? I'd go for the bigger but slower (unless you can get one of those new 200GB 7200rpm toshiba drives which is best of both worlds). Why wouldn't I go for the 7200 Rpm ? Well first, my internal is not my media drive. Even so, I've never actually had a problem with the slower laptop drives for capture or playback at a pinch, but I may have just been lucky in that regard. So, for me, given that discs have a habit of filling up with crap, and given it is not my primary media drive, then bigger is better.
RAM? As much as you can afford. 3GB is the current limit for the MBP's.
As we all know, OSes and app's have a RAM hungry nature which seems to know no bounds. As things progress, 3GB will not seem like so much.
External media drive? Yes of course, highly recommended. If you don’t have one then your internal disc will be eaten up by clip media in no time (especially if you opted for the smaller faster internal disc... And, as noted above, if you get an external drive for your media then the speed of your internal drive is les of an issue). There are a number of options for external HD. There is one primary questions that you need to answer. Do you envisage needing to edit in the field without any access to a power supply ?
If the answer is “yes”, then you need to buy a “bus-powered” solution ie one that can be powered just by plugging it into the laptop. This limits you to using a laptop hard disc in an external Firewire enclosure. As mentioned before, laptop drives have a smaller capacity than their desktop cousins (and they’re more expensive). The best bus-powered solution is either G-Technology’s “G-RAID Mini” or Lacie’s “Little Big Disk”. Both contain 2x160GB hard discs in a hardware RAID, and connect via Firewire 800. This makes them very fast, and gives them a larger capacity (320GB). They are very reliable but also very expensive. Single disc solutions are of course much cheaper. You can buy these from the big brand names too (Lacie’s “Rugged” line are supposed to be hard wearing), or you need not go with a ‘brand name’ drive at all. You can buy the discs and Firewire based drive enclosures separately in most computer malls, and then put them together yourself. These would not be RAID solutions of course, so not as fast and not the same capacity ... But much cheaper.
If “bus-powered” is not necessary then your other choices expand significantly. Currently the best (and fastest) option would be an SATA RAID. This requires using an ExpressCard/34 eSATA adapter in the laptop to provide the eSATA interface for the RAID. SATA drives/interface are very much faster than Firewire. You could add a single drive or an entire eSATA RAID. If SATA is overkill for your needs then you can choose a external firewire drive. My drive of choice for this is G-Technology’s “G-RAID” which has a large capacity, and is fast and very reliable. Again, its not cheap.
Don’t buy a USB harddrive. They cannot maintain a fast enough sustained data rate such as is needed for working with video.

Need help with Mac Book Pro?

When I start the mac book pro, the disk drive keeps making noise. The computer can't get any further. Its like its looking for a disc startup. I put the start up disk in there and now it doesn't do anything. Its almost as if it won't boot the hard drive. Any advice would be appreciated.
Thanks, Matt

+the disk drive keeps making noise. The computer can't get any further.+
That's sounding like a hard disc failure sadly ...
+I put the start up disk in there and now it doesn't do anything.+
Restart holding down the 'c' key to force it to Boot from the DVD, if that works select Disc Utility from the top menu bar and then 'Repair Disc' and 'Repair Permissions' on the Internal Drive. Post your results here.

Take each of these steps that you haven't already tried. Stop when the problem is resolved.
Step 1
The first step in dealing with a boot failure is to secure your data. If you want to preserve the contents of the startup drive, and you don't already have at least one current backup, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data that has changed since your last backup, you can skip this step.
There are several ways to back up a Mac that is unable to boot. You need an external hard drive to hold the backup data.
a. Boot into the Recovery partition, or from a local Time Machine backup volume (option key at startup.) When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in this support article, under “Instructions for backing up to an external hard disk via Disk Utility.”
b. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, boot the non-working Mac in target disk mode. Use the working Mac to copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
c. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.
Step 2
Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to boot, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can boot now, one of the devices you disconnected, or a combination of them, is causing the problem. Finding out which one is a process of elimination.
If you've booted from an external storage device, make sure that your internal boot volume is selected in the Startup Disk pane of System Preferences.
Step 3
Boot in safe mode. Note: If FileVault is enabled on some models, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Post for further instructions.
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 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.
When you boot in safe mode, it's normal to see a dark gray progress bar on a light gray background. If the progress bar gets stuck for more than a few minutes, or if the system shuts down automatically while the progress bar is displayed, your boot volume is corrupt and the drive is probably malfunctioning. In that case, go to Step 5.
If you can boot and log in now, empty the Trash, and then open the Finder Info window on your boot volume ("Macintosh HD," unless you gave it a different name.) Check that you have at least 9 GB of available space, as shown in the window. If you don't, copy as many files as necessary to another volume (not another folder on the same volume) and delete the originals. Deletion isn't complete until you empty the Trash again. Do this until the available space is more than 9 GB. Then reboot as usual (i.e., not in safe mode.)
If the boot process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
Step 4
Sometimes a boot failure can be resolved by resetting the NVRAM.
Step 5
Launch Disk Utility in Recovery mode (see Step 1.) Select your startup volume, then run Repair Disk. If any problems are found, repeat until clear. If Disk Utility reports that the volume can't be repaired, the drive has malfunctioned and should be replaced. You might choose to tolerate one such malfunction in the life of the drive. In that case, erase the volume and restore from a backup. If the same thing ever happens again, replace the drive immediately.
This is one of the rare situations in which you should also run Repair Permissions, ignoring the false warnings it may produce. Look for the line "Permissions repair complete" at the end of the output. Then reboot as usual.
Step 6
Reinstall the OS. If your Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
Step 7
Repeat Step 6, but this time erase the boot volume in Disk Utility before installing. The system should automatically reboot into the Setup Assistant. Follow the prompts to transfer your data from a Time Machine or other backup.
Step 8
This step applies only to older Macs (not current models) that have a logic-board ("PRAM") battery. Both desktop and portable Macs used to have such a battery. The logic-board battery is separate from the main battery of a portable. A dead logic-board battery can cause a gray screen at boot. Typically the boot failure will be preceded by loss of the startup disk and system clock settings. See the user manual for replacement instructions. You may have to take the machine to a service provider to have the battery replaced.
Step 9
If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store to have the machine tested. If you can't get to an Apple Store, go to another authorized service provider.
