MacBook Pro OS X Lion not rebooting
On powering up my MacBook Pro OS X Lion presents an Apple and a busy symbol, and fails to start.
My question is how can I resolve this?
I've tried the Apple disc utility which reports HD ok, not sure what to do next.
Startup your Mac while holding down the Command + R keys so you can access the built in utilities to restore OS X using OS X Recovery.

MacBook Pro 13" Retina will not reboot in Yosemite
I have a brand new -- the newest model -- MacBook Pro 13 in. Retina that was doing well with Mavericks. After having Yosemite installed it froze up when the top was closed, and now it will not reboot.
I tried holding the power button down for several seconds and then pressing the power button again, just long enough to get the start-up gong. Tried this three or four times. Each time the reboot stops when the progress bar on the screen, under the Apple logo, reaches just less than half way. Then nothing. Letting the machine sit for long periods while it works out its own problems does not help. No progress toward rebooting.
I have tried rebooting with and without the power cable attached.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 with Mountain Lion not downloading Printer Drivers
I have an Epson XP-300 All in One Printer. I tried downloading the software and its drivers from the installatioin CD and Epson Website but my Mac just won't do it. When I click Download on the Epson Site safari won't open the page. It tries to but then says "Safari can't open page". I am running Mountain Lion.
Help...anyone?Thanks for the quick reply Sig. I actually downloaded this file from the exact location you suggested last night. I then deleted the printer from "Printer and Scan" list and tried to add it again hoping it would solve the problem but now I can't even add the printer again since the Mac doesn't even recognize there is a printer in range. Still don't know what to do. Suggestions?? Thanks.

Have a macbook pro running osx lion. Connected a Kindle Fire using micro usb and the disk icon doesn't show up on the desktop. Also sometimes get a message sayiing computer doesn't recognize device. When I opened disk utilities the Kindle disk does show up there. What am I missing?

Kindle is connected directly, not thru a hub. Also called Amazon Kindle support, tech was baffled when I told her I was using a Mac. She said, "I'm not really familiar with apple products."
Precisely why it's not an iPad, and why it doesn't cost very much. An Apple rep would tell you how to connect an iPad to every computer.

I tried to airdrop Civilization V from a Macbook Pro with Mountain Lion to a Macbook Pro with Lion and it doesn't work. Other apps have but Civ V has not.
Likely because it's a not self contained and/or it's game and copy protected, so install it via the developers instructions instead, which likely means it will have ot be uninstalled off the first machine, the developer contacted for a new license key before installing on the newer machine.
If you want it on both machines, you will need to likely buy another license.
Most developers are fine with transfering license between machines, you have to contact them.
They just want to make sure it's only on one machine so they are not getting robbed. -
Hi,
I purchased Huawei Dongle and trying to connect with my new MacBook Pro (OS- Mountain Lion) USB port 3.0 but unfortunately it does not support.
When I plugged in my macbook the power is flowing in dongle due green light blinking twice in every 3 sec but no connection found or diver shown.
Please let me know how I have to use it. I got some suggestion for USB hub 2.0 but It does not make any sense and driver installation.
So please suggest proper direction to use it and provide link to install any driver.
Thanks
Tauheed AhmadYes Clinton I did same, but they were (Huawei customer support) surprised about this problem, They behave like they have no idea about USB 2.0 and 3.0 knowledge. They handsUp that reason I posted my problem in this forum.
So is there any better solution to use any mediator between these USB version handling, Please let me know.
Thanks

My macbook pro has mountain lion installed and it will not play dvds
my hubby's macbook pro has mountain lion installed, and will not play dvd's. It says it is unsupported, I also have a macbook pro but has snow leopard on it, mine will play dvd's. Please help me, I can't figure out why his won't play the same dvd's as mine.
The most frequent problem in an optical drive is a dirty lens. Use a lens cleaning DVD, a few shots of compressed air in the slot or a fine microfiber cloth (eyeglass lens cloth) wrapped around a business card and gently inserted inside the slot. If no success, the Apple store genius bar is the next stop.

when printing from aperture my margins are unequal, even if i set my margins they come out bigger one side and not the other. i am using a macbook pro running osx lion and printing with a canon pro 9000.
please can anbody help or advise?You didn't mention any color calibration being done on your monitor. This is an essential part of any color-correct workflow. What are you using to calibrate your monitor (and your printer)?
Print profiles (for soft-proofing as well as printing) are for specific combinations of paper & printer. The nine you have are each, most likely, for a common paper (perhaps mfr'd by Canon) to be used with your printer.
I don't know what you mean when you say "I choose a high standard print option".
Have you read the User Manual chapter on printing?
Printing Your Images
There is also a good appendix on calibration:

I have MacBook Pro with Mtn Lion. When cover is down, FaceTime will not ring the Mac from iPad. Can I set up to ring Mac
Well first, I must say "Yikes!!!" I didn't know anyone still used Word Perfect. That's an old school word processor right there... haha.
Okay, in all seriousnous, when saving your files in Word Perfect, use the Save As feature, and select a different format. Word Perfect's format is likely not going to be opened by any of the popular word processing software. I would try saving the document as RTF (rich text format), which is a universal standard across word processors. This way, you can open the document on your Mac, or any other machine.
Now, I'm also assuming that you have a word processor installed on your Mac. Right? Maybe Word? Maybe Pages? If you don't have a word processor, you'll need to get one. If you don't want to spend the $10 on Pages, consider downloading Open Office (http://www.openoffice.org/download/). This will give you a free word processor that you can use on your Mac. -

First the good news. My 2008 MacBook Pro, which used to not fall asleep unless forced to do so (lid closed or command issued) now falls asleep. The bad news is that it will fall asleep even if a program is doing something and I'm not physically doing anything. More accurately it will fall asleep when uploading to Box.net, or when downloading map updates for my GPS. It also falls asleep when EyeTV is converting shows, but not when it's recording shows. I have third party apps that can keep it awake, but shouldn't my MBP recognize that something is happening and to not fall asleep?

Why does safari not update to 5.1 on macbook pro when running lion 10.7.1
my macmini is running lion server and safari 5.1. my iMac is running lion and safari 5.1. my macbook pro is running lion and safari 4.0.4 and update is stating that there are no updates available.
how does one force an update to safari 5.1 for lion in this situation?my macbook pro is running lion and safari 4.0.4 and update is stating that there are no updates available.
Did you move or copy the Safari application? It should be in the Applications folder at the top level of your startup volume.
There is no downloadable installer for the Lion version of Safari. -

Fixing a Mavericks Installation Problem
How to manage a failed OS X Mavericks installation | MacFixIt - CNET Reviews.
Try these in order:
1. a. Resetting your Mac's PRAM and NVRAM
b. Intel-based Macs: Resetting the System Management Controller (SMC)
2. Restart the computer in Safe Mode, then restart again, normally. If this doesn't help, then:
Boot to the Recovery HD: Restart the computer and after the chime press and hold down the
COMMAND and R keys until the Utilities 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.
3. Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the Utilities 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. Select Restart from the Apple menu.
4. Reinstall Lion/Mountain Lion, Mavericks: Reboot from the Recovery HD. Select Reinstall Lion/Mountain Lion, Mavericks from the Utilities menu, and click on the Continue button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless. -
Upgraded macbook pro to mountain lion, get the following message
"the backup disk image "......." could not be accessed (error 112)
I've tried many of the suggestions from other discussion threads, still unable to get anything to work. Have 4 other computers backing up to the same time capsule, all of them are functioning normally, however they are not upgraded to mountain lion.
Suggestions?This simple procedure will clear your Time Machine settings, including your exclusion list. If you have a long exclusion list that can't be recreated easily, you may prefer a more complicated procedure that preserves the exclusion list. In that case, ask for instructions. Otherwise, do as follows.
Triple-click the line below to select it:
/Library/Preferences/com.apple.TimeMachine.plist
Right-click or control-click the highlighted line and select
Services ▹ Reveal
from the contextual menu. A Finder window should open with a file selected. Copy it to the Desktop. Then move it (the original, not the copy) to the Trash. You'll be prompted for your administrator password. Reboot, recreate your settings in the Time Machine preference pane, and run a backup to test. If TM now performs as expected, delete the file you copied to the Desktop. -
Hi pls help me my MacBook pro is x could not be installed on your computer
Hi pls help me my MacBook pro is x could not be installed on your computer
OK - with that information I can help.
Reboot your computer and hold down the Command and R keys. This will take you to your Lion Recovery partition. Select the Macintosh HD partition (or whatever you've named your start-up drive) and first verify it. Errors will probably come up. Then choose Repair. After the repair you should be able to reboot and install Mountain Lion.
Call back with any problems...
