Macbook pro 2012 does not work after update, macbook pro 2012 does not work after update

After 6 weeks i started my macbook and installed q new update now it has a problem to start and restarts all the time again and again

Make certain that your MBP is connected to an AC source and is charging or charged.
Then try a SMC and PRAM resets:

HT4718 I have a new MACBOOK PRO and after running updates IPhoto does not work

After installing Iphoto 9.4.1 from the MACSTORE updates Iphot will not run. I downloaded (.4.1 again and tried to install but it says that the update must be done from the Mac store. But I do not show any updates when checking the mac store and do not know how to proceed. I just purchased the computer and set it up on Saturday. I transferred files from an older Macbook pro.

Hi j,
Gray Screen at Startup (try Safe Boot)

MacBook Pro Late 2011 Model - Does not work after Yosemite update

i recently updated my OS to Yosemite and had in problems for two days but yesterday it ceased to work in the middle of printing a document.
I need my laptop back up and running since I have school exams soon and vital information and files are in this laptop.
i Have never had a problem with the laptop before.
Issues that I have had
logging in takes at least 20 minutes
cannot progress further than that, desktop is blank and nothing loads, only the dock.
battery drains extremely fast
Safe boot does not even load
I've tried clearing that VRAM and the other one.
Cannot access anything at all
This is appalling and at the worst possible time.

Please describe exactly what you're doing and what happens.

Why does power nap time machine backup not work on my August 2012 macbook pro retina?

Hello. I got a MacBook Pro with retina display in August of this year 2012. I have done the SMC ? firmware update and I have 10.8.2 installed on my machine. Power nap still doesn't seem to work. I have the button in energy saver preferences and I have clicked it so it looks like power nap should work. When I am running Time Machine backup with the time capsule and I close the lid (plugged into power) it appears that no progress is made when I reopen the lid. I have closed the lid with activity monitor running and with network displayed. When I reopen the lid it may take up to one minutes to come out of sleep. When it does come out of sleep I can see that there has been no network traffic. Eventually, time machine backup resumes and I can see several megabytes per second. When I closed the lid overnight, just to make sure backup didn't restart after lid closing, I saw that no progress had been made in backup when I reopened the lid.
What options are left if I already have 10.8.2 and I have done the required firmware? One person has mentioned a clean install but I really don't like to have to reenter all the different passwords and all the different preferences again unless that's absolutely necessary. Are there any other options left to try before a clean install?
One other bit of information. I have filevault turned on; however, it looks like others have a working power nap even with file vault enabled. If this is not an option, the power nap button should be grayed out when the machine is in filevault.
Thank you for any help.

Yeah I still have the same problem BTW; it still does not work.
The second I open the lid and take it out of sleep mode, it starts to backup automagically, but when it's sleeping EVEN when it's connected to AC power, TM backups do NOT work to my OS X Server.
I don't understand what the problem is here.
I didn't before but I do have FileVault turned on now -- should that make a difference?
In either situation it didn't work, but now that I think about it, I could understand why it wouldn't backup while asleep. Apparently the encrypted volume will stay encrypted during sleep and even at the lock screen; it's not until you open the lid and log in from the lock screen that it will unlock the encrypted boot volume.
But even still, I did *not* have FV turned on before, and this still did not work.
Is there some third party solution that can do what I want this to do?
Here's my use case:
1.) I have a mac mini at home that I use when I'm at home; it runs OS X server.app (bought and paid for) and has TM server turned on.
2.) I have a laptop that I mainly use at work and I don't use at all when I come home (ie. when I'm ready to head home for the day I close the lid and don't open it until I'm back at work the next day, but the laptop does come home with me every day).
What I want to have happen is this:
1.) The minute my laptop enters my home wifi lan (even though it's still asleep with lid closed) I want it to automatically backup the boot drive.
I thought that's what Power Nap was supposed to do, but then I found out that in order for this to work, you have to be connected to AC power; so then I tried that -- ie. every day I come home, I put my laptop in a docking station that has AC power, but TM backups while lid closed / sleeping STILL do not occur!
Thanks for your help everyone...Looking forward to a solution that works.
EDIT:
I found this thread:
https://discussions.apple.com/thread/4158709
"It looks like Power Nap doesn't perform Time Capsule backups when the MacBook Air screen is closed."
So apparently that is yet *another* requirement to get powernap working. The lid can not be closed.
What is the difference between sleep with lid open and sleep with lid closed!?

MacBook Pro Mid 2012 not starting up after Yosemite Update

I'm using a MacBook Pro mid 2012 model , enrolled into Yosemite Public Beta Program ...
After the official public launch , app store suggested that i rather update from beta 5 to beta 6 , as downloading extra 5 gig of OS data seemed unnecessary for me , I just updated from the app store.
Post the update , after shutting down my MacBook , I tried starting it up after 8 hours , it failed to respond to any of my prompts .
Keyboard not responding
Power Button not responding
Li-Po Battery indicator alone works ,
When plugged MagSafe , it indicates charging .
The Sleep Indicator (in the front - that of hard disk drive ) blinks occasionally.
Later, when i tried powering up with MagSafe , It booted luckily , after some 20 hours of work , i shut the system down ,
Again when i tried booting up , it failed .
The problem persists since 3 days.
I tried booting up in Safe Mode - No result
Tried Verbose Booting up - No result
Cleared NV RAM - No result
Cleared SMC as Apple instructed for Intel Based MacBooks - No result.
Removed Battery and kept aside for a while , After an hour tried powering up , It booted up , Went till Apple Logo , The loading bar was some 45%
Then it started to go down with a black screen ,
It never starts up again.
After regular intervals of removing and installing battery , it starts up to white screen and goes off.
I am really worried and desperate now.
I am not sure whether my HDD is dead or my Battery is dead or my Logic board is dead or my Yosemite Install was not right ?
After hours of online research , nothing seems to be helpful .
People at Apple Care (Premium ReSeller , India) are so irresponsible in attending the issue ,
They say its helpless without even doing some basic troubleshoot.
Where would it have went wrong and What am i supposed to do now ?
PLEASE HELP !!

darkrider92,
I have the same model MacBook Pro as the one that you got from your mom. Were you able to install the 10.6.8 update successfully onto the factory drive? Were you using the factory RAM when you tried to install the 10.6.8 update on the SSD?
Have you checked the Web site of the SSD’s manufacturer, to see if there’s a firmware update available for the SSD?
You can download the 10.6.8 update outside of Software Update from Apple here; in case you need to try to install this update several times, running it from your local disk would be more convenient than waiting for it to download again.

After I updated my OS on my MacBook Pro, my mousepad does not scroll with a swipe as expected. Any recommendations?

After I updated my OS on my Macbook Pro, the mouse pad does not swipe as expected. I have to use the arrow keys. Any suggestions?

a brody, I will take a look. The internal drive works (i.e., the battery, it spins, etc.) it just has a bit of trouble recognizing all CD's so I tend to use the external one since it works consistently. Do you still think this might be the issue? The apple store told me a week after my extended warranty ran out that the drive should be replaced but that an external drive is not an isse, but that was a while back and this problem just started.

FaceTime and Messages stopped working on my MacBook after I updated to Yosemite. Handoff does not work either. How can I fix this?

Before I updated to Yosemite, I could FaceTime other people and Message other people with the MacBook Pro apps. However, after I updated to Yosemite, they stopped working. I get "not delivered" feedback on Messages, and "call failed" on FaceTime. I made sure that both have the correct emails checked and unchecked in the settings as my iPod, and made sure that the "make calls from" or "begin new conversations from" coincide with my handheld Apple media player.
Am I not doing something? Am I doing something wrong?
Any feedback would be appreciated!
Thanks!

Please read this whole message before doing anything.
This procedure is a test, not a solution. Don’t be disappointed when you find that nothing has changed after you complete it.
Step 1
The purpose of this step is to determine whether the problem is localized to your user account.
Enable guest logins* and log in as Guest. Don't use the Safari-only “Guest User” login created by “Find My Mac.”
While logged in as Guest, you won’t have access to any of your documents or settings. Applications will behave as if you were running them for the first time. Don’t be alarmed by this behavior; it’s normal. If you need any passwords or other personal data in order to complete the test, memorize, print, or write them down before you begin.
Test while logged in as Guest. Same problem?
After testing, log out of the guest account and, in your own account, disable it if you wish. Any files you created in the guest account will be deleted automatically when you log out of it.
*Note: If you’ve activated “Find My Mac” or FileVault, then you can’t enable the Guest account. The “Guest User” login created by “Find My Mac” is not the same. Create a new account in which to test, and delete it, including its home folder, after testing.
Step 2
The purpose of this step is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
Please take this step regardless of the results of Step 1.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.
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. Ask for further instructions.
Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
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.
Test while in safe mode. Same problem?
After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of Steps 1 and 2.

Hello. I recently pieced together a late 2008 MacBook Pro 15". Everything works fine except the battery constantly goes between "not charging" and "calculating" or, rarely "charging". It does charge after a long while and will report that it is charged.

I have reset the NVRAM and the SMC a couple of time but that didn't work so I ran an Apple Hardware Test and while testing the logic board it gives the following error:
4SNS/1/40000000 LB1T
I've done some research and found this is a temperature sensor related to the battery, but cannot find where the sensor is located in the computer. Would you know how I can find the sensor to test it? Could my battery problem be related to something else? Would a fresh install of Lion help?
Thank you!
Mike
Two pieces of information that may or may not b helpful, the hard drive is from my early 2008 MBP and the only test disc I have access to is from an iMac.

Why do you have LION installed on that older machine?
So you say you built a macbook from a bucket of parts eh? Kudos
heres a pic of the battery temp sensor

After 10.5.5 update, MacBook Pro LCD not working.

After I updated to 10.5.5 my MacBook Pro worked fine, until I put it to sleep. Now, the screen won't come back on even after restarting and removing the battery.
Also, I can't even get an external monitor to work.
I can hear the volume idicator sounds working when I adjust the volume so I know that the computer is working, just not the screen.

No guarantee but there are two things that sometimes help:
Reboot into the Safe mode (hold down Shift key on boot) but when you get to the login screen click restart.
If that doesn't help, try resetting the PRAM.

Built in Audio not working in MacBook Pro after update to 10.7.3

The Built In Audio is not working in My MacBook Pro (Early 2011) after update to 10.7.3; I tried resetting the PRAM and SMC but it didn't helped me out. I can get audio only if i reboot my mac from Safe Mode or reboot after Repairing Disk Permissions in disk utility using the Recovery Partition;. If i make a normal restart or just startup then the built in audio disappers (audio is displayed gray in the menu bar) . Everything was working well with the 10.7.2
- Audio Works well with the Boot Camp Partition. and There is a sound during boot up.

I dont have any backups and i dont have time capsule or an external hard drive ready to be used for backup.
My macbook is my the only one computer. The problem is that the animation is lagging when i change the window to dashboard or safari or mail or another window. Inspite of this my macbook works well.
But 5 minutes ago, I noticed that if i run autocad on my mac- the lags go away!!!!

After updating to Yosemite 10.10.2, macbook air Wifi does not work. What to do?

I upgraded from Maverick to Yosemite in Nov 2014 & my mack book air 2011 model became slow. Yesterday after downloading & updating 10.10.2, Wifi does not work, it prompted Gatway Time out. Anybody can help please? Dr. Mostafa

Moreover I am to add, in the same network, windows PC Wifi works & more interestingly Macbook with Maverick also connects with the same Wifi, I mean to say this is the problem with Yosemite 10.10.2. Before updating on Sunday last, my Wifi was working nicely.

Actually it sometimes gets a little further, the display will dim and the pointer will appear and then whoop it will turn off. if i do a verbose start up, it will finish all the steps, the white screen will appear and dim and then it will turn off.
