I Really need help if the same happened to you. Thanks

You can try the following steps:

Hold down the key until you hear three chime sounds
Restart your mac while holding down the shift key.
it will start your computer in safe mode.

Hi r,
Make sure you close iTunes before shutdown. And you're quite welcome.

Safe Boot disables several things, and you can look at the list and see if you can find the culprit. As Linc says, if you still have a problem, post a new topic so that it will get the attention it deserves.

If the Mac is too hot to touch, take it in for service.

When i turn on my macbook pro why does a bunch of things pop up

It's the Resume feature of Lion:
Managing Mac OS X Lion's application resume feature.
If you shutdown your computer you should get a dialog asking if you want applications to resume on the next startup. Simply uncheck the box to prevent that from occurring. Open General preferences and uncheck the option to Restore windows when quitting and re-opening apps. You can also install a third-party utility to control resume features on individual applications: RestoreMeNot or Application State Cleaner.

It turns out that iCloud caused this issue. When I turned iCloud off my login screen was completely normal.

Last night I did an update and now when I turn on my macbook it just goes to the white screen with the apple and stays like that.

Take each of these steps that you haven't already tried. Stop when the problem is resolved.
To restart an unresponsive computer, press and hold the power button for a few seconds until the power shuts off, then release, wait a few more seconds, and press it again briefly.
Step 1
The first step in dealing with a startup failure is to secure the 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 the last backup, you can skip this step.
There are several ways to back up a Mac that is unable to start. You need an external hard drive to hold the backup data.
a. Start up from 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.” The article refers to starting up from a DVD, but the procedure in Recovery mode is the same. You don't need a DVD if you're running OS X 10.7 or later.
b. If Step 1a fails because of disk errors, and no other Mac is available, then you may be able to salvage some of your files by copying them in the Finder. If you already have an external drive with OS X installed, start up from it. Otherwise, if you have Internet access, follow the instructions on this page to prepare the external drive and install OS X on it. You'll use the Recovery installer, rather than downloading it from the App Store.
c. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, start 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.
d. 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
If the startup process stops at a blank gray screen with no Apple logo or spinning "daisy wheel," then the startup volume may be full. If you had previously seen warnings of low disk space, this is almost certainly the case. You might be able to start up in safe mode even though you can't start up normally. Otherwise, start up from an external drive, or else use the technique in Step 1b, 1c, or 1d to mount the internal drive and delete some files. According to Apple documentation, you need at least 9 GB of available space on the startup volume (as shown in the Finder Info window) for normal operation.
Step 3
Sometimes a startup failure can be resolved by resetting the NVRAM.
Step 4
If a desktop Mac hangs at a plain gray screen with a movable cursor, the keyboard may not be recognized. Press and hold the button on the side of an Apple wireless keyboard to make it discoverable. If need be, replace or recharge the batteries. If you're using a USB keyboard connected to a hub, connect it to a built-in port.
Step 5
If there's a built-in optical drive, a disc may be stuck in it. Follow these instructions to eject it.
Step 6
Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to start up, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can start up 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.
Step 7
If you've started from an external storage device, make sure that the internal startup volume is selected in the Startup Disk pane of System Preferences.
Start up in safe mode. Note: If FileVault is enabled in OS X 10.9 or earlier, or if a firmware password is set, or if the startup volume is a software RAID, you can’t do this. Post for further instructions.
Safe mode is much slower to start 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 the login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
When you start up 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, the startup volume is corrupt and the drive is probably malfunctioning. In that case, go to Step 11. If you ever have another problem with the drive, replace it immediately.
If you can start and log in in safe mode, empty the Trash, and then open the Finder Info window on the startup 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 restart as usual (i.e., not in safe mode.)
If the startup process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
Step 8
Launch Disk Utility in Recovery mode (see Step 1.) Select the 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 restart as usual.
Step 9
If the startup device is an aftermarket SSD, it may need a firmware update and/or a forced "garbage collection." Instructions for doing this with a Crucial-branded SSD were posted here. Some of those instructions may apply to other brands of SSD, but you should check with the vendor's tech support.
Step 10
Reinstall the OS. If the Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
Step 11
Do as in Step 9, but this time erase the startup volume in Disk Utility before installing. The system should automatically restart into the Setup Assistant. Follow the prompts to transfer the data from a Time Machine or other backup.
Step 12
This step applies only to models that have a logic-board ("PRAM") battery: all Mac Pro's and some others (not current models.) Both desktop and portable Macs used to have such a battery. The logic-board battery, if there is one, is separate from the main battery of a portable. A dead logic-board battery can cause a startup failure. Typically the failure will be preceded by loss of the settings for the startup disk and system clock. See the user manual for replacement instructions. You may have to take the machine to a service provider to have the battery replaced.
Step 13
If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store, or go to another authorized service provider.

Macbook pro will not advance beyond grey screen at beginning of boot

macbook pro will not advance beyond grey screen at beginning of boot

Try performing an SMC reset. I am having this problem also.
To perform an smc reset:
1. Shut down your Mac, leave the MagSafe charging in.
2. Push three buttons: shift + control + option and the power button. Push and release together.
3. Wait a few seconds then turn on your Mac as normal.
Hope that works out for you!

When I turn on my MacBook Pro a box prompts up and it disappears right away. How can I stop this from happening?

I'm new in the Mac World. In November I bought a MacBook Pro. I love my MacBook, however, a couple of days ago when I turn on my MacBook and log in, a window or box prompts up for about one second and then dissapears. I'm afraid that may be a virus or trojan that may be running behind the screen. How do I fix this? Are there any applications that I can run to detect what is happening to my computer.
Thank you for your help!!!

It was very hard to see what the box says because the message displays for less than one second. However, I was able to record it with my iphone and pause it until I got a shot of the message. The box says the following:
"Do you want the application “java” to accept incoming network connections?
Clicking deny may limit the application’s behavior. This setting can be changed in the Firewall pane of Security preferences."
I did make some changes. I will see if it works.
Thank you!!!

How do I stop Photoshop from launching when I turn on my MacBook Pro?

I subscribe to Adobe CC. Every time I turn on my MacBook Pro, Photoshop CC launches. I want this to stop. When I right click on the Photoshop app > Options > Open at Login is NOT checked. And in System Preferences > Users & Groups > Login Items > Photoshop is not there. What can I do? I am sure it is a simple fix. Thanks!

As I mentioned when I right click on the Photoshop app in the dock > Options > Open at Login is NOT checked. And in System Preferences > Users & Groups > Login Items > Photoshop is not there in the list. I do not have any utilities installed that automatically launch applications and I do not mess with scripts or even know how to.
I tried calling Adobe's poor outsourced customer service and was told there was a 2-5 minute wait, but after waiting 22 minutes, I had to hang up.

How can I shut off the automatic login when I turn on my MacBook Pro?

Ever since I updated to Yosemite I have been forced to enter my password whenever I turn on my MacBook Pro. I went to System Preferences/Users & Groups and see that the automatic login option is set to off, but it is shaded and I can't use the dropdown menu, even though I've unlocked it.
Is this a common issue? Am I just going to have to get used to signing in every time? I'm the only one who uses it, and it's a little annoying.
I've tried searching for help in the discussions and also on google, but I'm not finding any answers.
Help, please!

Did you turn on FileVault when you upgraded to Yosemite? If it is on then a login password is required (sort of obviously). You can tell whether it is on by going to Apple Menu > System Preferences > Security & Privacy and click FileVault at the top and see if the words "Turn off FileVault" are in the button. I'm the only one who uses my Mac also, but the remote possibility of it being stolen makes it worth it to me to have FileVault turned on and a password required.

Brand new MacBook Pro doesn't get past grey screen (with spinning gear)

Hello,
I'm a new Apple customer - I bought a new 15" MacBook Pro during the Black Friday sale last week. Since purchase, I've installed the software I needed (Office, CS4) and have used it to browse the web and write emails.
Today when I tried to use it, I simply got to the grey screen with the Apple logo on it and the spinning gear device underneath - got absolutely no further.
I have done the following (running from mains adaptor - but the battery indicator is reporting 7 lights anyhow):
1. Boot from the OSX Install Disc, and run the disc repair utility. It reported no problems found. Restarted... same problem.
2. Boot holding down SHIFT to go into safe mode. Underneath the spinning gears, a progress bar filled up to 100% and then disappeared; leaving the grey screen, logo, and spinning gears. Nothing further.
3. Boot holding Option, P, R as per the manual to reset the PRAM. According to the manual there should have been a chime/beep - there wasn't. It just sits on the grey screen, logo, spinning gears. Nothing further.
Right now I've got a £1300 MacBook Pro less than a week old and it appears to have just packed up.
Am I missing anything here, or should I just return it?
Thanks,
Chris

Definitely take it back!
My friend bought a new iMac from the Regents St. store a few weeks ago, just before the update to the new models came out, and after a week she couldn't get it to boot. I felt very embarrassed as I had persuaded to her to switch to Mac after years of PC woes, so a broken mac after a week didn't look do me any favours. The genius guys didn't mess around, they took back the dead one and gave her a new one, this time she got the new version, they also threw in iWork free as a good will gesture. New one is running fine.
If you haven't already got Applecare, I highly recommend buying it within the next 12 months. I have needed it on a couple of occasions after the standard warranty ran out and the tech support has been brilliant, got me working again no quibbles.
