After updating iTunes and rebooting MacBook Pro does not reboot.

So after installing the update of the new iTunes the system needed to reboot. Screen remains black, battery is full and even with connection to the power network. When pressing the power button you hear the system starts working but stops after unpressing the power button. Also no sound of any HDD or other lights start working (apart from the green power light on the battery at the back / power network) Also the small white light next to the screen opener just goes on for 3 seconds or something. My MacBook Pro is from October 2008 and had further all available updates and 4GB of RAM. Anyone a solution?
Thanks in advance

TS1365 My MacBook Pro will not startup. At all. The suggestions from Apple Support are not helping. At all. Someone help?!?

My MacBook Pro will not startup. Its not responding at all. Does anyone have any suggestions on how I can correct this?

HI Catherine,
First, make sure it it shut down by holding down the power button for 5-10 seconds. Plug in the power adapter. Press the power button and hold down the shift key to see if you can start in Safe Mode.
If the power adapter and/or battery are known good, the next thing I'd check would be the RAM to make sure it is securely seated. If batt and/or power adapter are questionable, then you'll want to find one or both and try them out; if you don't know someone with a similar MBP, this might be most easily accomplished by making a free appointment at an Apple Store "genius" bar.

MacBook Pro does not start. "traffic sign" on the screen

Hi,
After unistalling Norton AntiVirus as it had expired i shut down my machine. Now when starting it the grey apple is on the screen and below it the little thing that "goes around". After a while the grey apple changes into the "traffic sign" (a circle with a diagonal line going from 10 o'clock to 5 o'clock within the circle) underneath the little thing goes around for ever.
Can somebody please explain what's going on
thanks, pyry

Well, well well! So close and yet so far away. I give full credit to Graham. Without him I would be nowhere in this case, And I got it working with the help of his advice. Here's what i did
1. zap the PRAM - no startup effect
2. Start with option key down - no effect
3. start with shift key down - yes, it started as "safe boot". No internet connections etc but anyways.
4. Followed Grahams disk utility advice, everything settled except for something with ARDAgent (should not affect this I would think)
5. system preferences defined correct startup disc. Locked the setting, gave restart command via system settings button
6. machine restarted beautifully - gave full credit to Graham
but...
after closedown tried to restart machine again and "traffic sign" appeared. I can now start my machine via the shift button and then restart it via the systems preferences startup disc restart button. I do not however understand what is going on. I try to lock the startup disk via the system preferences but each time after startup when I go in there to check I see the lock sign as open.
Can someone please advice...

HELP! MacBook Pro won't turn on - loads up to the grey loading screen for a while then crashes., HELP! MacBook Pro won't turn on - loads up to the grey loading screen for a while then crashes.

Was using it fine then I rested my iPad mini on the keys and the screen went black and then came back but then froze for a little bit the audio went then after a bit it turned it self off and when I try and turn it on its loads to the grey loading screen loads for a bit then crashes - please help, I have got very important data on there that I need to access, thank you.
(PS I have booked a genius appointment for 3 days time but really need to use it before then)

No backups? Then I would, were I you, definitely order an inexpensive USB enclosure to try to rescue the files. Most companies in the US ship to the Phillipines, don't they? Where do you usually shop for computer gear? I don't know how much space/speed you really want but Seagate's 1 terabyte SSHD is an economic route to go for the 'feeling' of a SSD. I can also recommend Hitachi and Toshiba drives.
Just make certain that you get the right form factor - 2.5" x 9.5mm. You can get drives a bit thinner and a bit thicker, but I would stay close to that thickness range at any rate.
Good luck,
Clinton

Mac Pro recognizes n52te on Lion but Macbook Pro does not

I've been using a Belkin n52te for years with no problems. I know Belkin doesn't support it any more so there will not be a new driver. But I have an interesting problem. I upgraded to Mac OS X Lion recently on both my Pro and MB Pro. The weird thing is that the n52te driver still works and recognizes the n52te on the Pro, but not on the MB Pro. On the MB Pro the USB recognizes the device, and i can use its factory default settings, but the n52te driver does not recognize that the device is plugged in so I can't use any of the preference set ups that I have for it. This strikes me as odd since the OS is the same and the USB handling seems to work. So my question is why? why does it work on the Pro and not the MB Pro?
my Pro is a 1,1 and my MB Pro is a 4,1

I don't know why the device is fully functional on one Mac but not the other, but have you tried finding the customized preference file on the Mac Pro and then copying it to the MacBook Pro (after backing up the factory default preferences on the MacBook Pro just in case)?

IMessage on MacBook Pro DOES NOT allow me to sign in with my Apple ID. What can I do?

Macbook Pro does not boot from install CD, boots from non-apple live CDs

This story begins with my macbook becoming entirely unresponsive while just sitting around with the desktop in focus. My current problems begin with the third of such freezing events. It felt like the hard drive had stopped responding since everything looked fine and I could move my mouse, but as soon as I attempted to access anything that depended upon the file system (ie everything not already in memory) that thing I attempted to access would freeze up as well. The only thing I can do when these happen is to force a shutdown.
The three times I have had these problems I would be greeted with the flashing folder-and-question-mark. So, for the third time now I threw in a live CD I have and ran DiskWarrior and DiskUtility and fsck and everything I could possibly need to recover the system. Each of these programs ran through their routines and reported that it had either successfully made repairs or the disk needed no repairs and was A-OK!. S.M.A.R.T. reports that the drive is perfectly fine as well.
Now, though, whenever I try to start up my computer I'm greeted with the normal grey apple startup image, the folder with the question mark, and also the prohibited sign (grey circle with a slash through it). This is the first time that running the disk repair programs has failed. Expecting a crashed hard drive or something equally fun I threw in the live CD again and attempted to recover my data. The thing is, I was able to navigate the file system perfectly with terminal and didn't even need any data recovery tools. So, at least my data has been safely backed up.
I've tried booting into single user mode, but it seems that DiskWarrior helped my computer in an assisted suicide of sorts as boot.efi is sitting in a DiskWarrior recovered folder and the mach kernel has been entirely misplaced. Immediately I restart, throw in the first Macbook Pro installation CD, and hold down C in an attempt to reinstall the system.
Here is my current problem: Whenever I attempt to boot from any of the installation CDs that came with my laptop, the laptop will begin to boot from the CD and show a grey screen as it begins reading from the disk, but before the spinning gear or grey apple appears the laptop simply restarts and attempts to boot from the disk again.
This boot-restart process loops infinitely with every Apple-provided installation CD I have tried. The laptop never progresses past a grey screen, instead restarting and happily chiming. However, I have been able to boot from a non-Apple Live CD that I own every time I have tried; moreover, the hard drive is perfectly accessible and shows no errors from any program I run. When I hold option upon startup it shows the drive and lets me boot into it (but then the problems I have described pop up). I have also tried resetting PRAM and NVRAM with no success.
Does anyone have any suggestions for how to boot into the live CD? Or would I be better off making sure I have backed up all of my data and then wiping the drive for a fresh install?

I am having the exact same issue. I can only log into the system in safe mode. Holding down the Shift key when turning the machine on, until the log window appears.

Macbook pro does not respond to bluetooth keyboard and mouse at login screen

i've seen this question floating around and i don't think i've found one that has been resolved. i'm hoping someone may have an answer by now.
i do not have this issue when i boot into windows 7 (bootcamp) the macbook pro responds to keyboard input and mouse input immediately on the windows 7 login screen. when i boot into mac, there is no response from either. i've seen suggestions of waiting for 30 secods. i still get nothing after waiting for over a minute.
what i do right now is use the built-in touch pad and keyboard of the macbook pro to get past the login screen. once i'm logged in, i can see that the bluetooth devices are not yet connected (the three dots that go across the bluetooth symbol at the top right of the screen are not yet there). then after a while, maybe about half a minute, the bluetooth keyboard and mouse are connected and i can use them normally.
it is not a big deal but it is very annoying.
i am using a logitech bluetooth mouse (v740) and an adesso bluetooth keyboard (wkb-4000bm). i also tried an azio bluetooth keyboard and had the same issue. all these keyboards are made for mac.
thannks in advance.

just a correction, the keyboard and mouse don't always automatically reconnect once i'm logged in. most of the time i have to go click the bluetooth icon at the top right of my screen, select the mouse and then select "connect". i have to do the same to the keyboard.

My MacBook Pro does not startup

My MacBook pro will not startup. I get a blank grey screen no logo appears so I can't chooseadiffer t drive nor boot from DVD. Safe mode and verbose mode also don't change blank screen.

It was running slow with the colored spining appearing often. This started happening weeks ago with Yosemite so I formatted the disk with the DVDs that came with the mid 2011 MacBook pro, 10.6.8. I then installed Yosemite on an external drive and this morning i was booted from the external hd with Yosemite and it stopped recognizong mouse clicks so I forced a restart and now I'm stuck with the blank grey screen. Safe mode and verbose mode also do not work.

Lao Bo,
yes, you can locate and copy a file from your HD to a USB key using UNIX commands. If you know the exact name of the file which you’re trying to locate, try this:
find / -iname filename -print
This command will search your entire internal disk for the particular filename. If you know that it’s within a particular user account, then you can save search time with this variation:
find /Users/username -iname filename -print
Either variation of this command will print all files found which have the given filename. Presuming that you’re able to identify the correct file, you can copy it to a USB key using the command
cp -p filename_returned_by_find /Volumes/USB_volume
If you’re not sure which volume name your USB key has, this command will show you what the possibilities are:
ls /Volumes
Please let me know if you have any trouble with these commands.

Video and audio not synchrone with apple tv after update mountian lion on macbook pro

i have a problem with my apple tv. after i bought and instaled mountain lion on my mac book pro i have trouble with apple tv and my laptop. when my laptop conects with apple tv most of the time my wifi doesnt work on my macbook but on my apple tv it stil does work. when it does work and i play a movie of my own by using itunes the first second the video and audio is synchrone but after that audio is at normal speed but the video gets behind. and i am getting sick of it. does sumbody reconize the problem and can help me with this problem?????

Same issue here- I can airplay my amazon prime library just fine from my iphone 5 but on my macbook- (mavericks, 15 inch 2013 retina with quad core i7, nvidia 650 M and SSD) it just sputters and lags.
I have noticed web video is considerably worse than local content, giving me pauses of up to 2 or 3 seconds in which video stops but audio continues in the amazon player. Youku video, however, seems relatively stable. Our subscription speed is 25 mbps, so that should be plenty to stream SD video from Amazon and doesn't account for why it would be nice and stable from the iphone, but not the mbp.
Playing light, locally hosted steam sidescrollers like Limbo is better but gives periodic drops in framerate on the Tv. when mirroring the framerate remains steady on the MBP screen.
Games airplayed from my iphone seem relatively stable, though with a noticably lower framerate on the TV than on the phone.
It seems these issues have abated considerably since yesterday's Apple TV update, but are still curious nonetheless and I'm not sure that the update yesterday was specifically meant to address those issues or if I'm just getting a time with less network interference now.
Comcast recently installed a new router/modem/phone combo, replacing our old separate modem and router setup. I'm going to test if putting the network on a different channel helps.

The sound on my Macbook Pro does not work.

The sound on my Macbook Pro does not work. When we press the volume buttons, the sound icon pops up, but the bar is full with a small "Does not work" circle below it, and nothing happens when I hit volume up or done. I went into system preferences, but there aren't any options there that I can see to change it.

"Unfortunately, it doesn't provide any help for a MacBook Pro, other than indicating to call Apple Support" (sic).
Au contraire. TS1574's title and affected products are thusly:
"Troubleshooting issues with no audio from built-in speakers on Macs
Products Affected Mac mini, MacBook, MacBook Pro, iMac"
As a result, the instructions of the article are relevant. To be sure, follow those steps, the last of which is to contact Apple.
So, by way of reminder, here are the steps to troubleshoot the audio on your MacBook Pro. There is no red light, so the port is likely fine. Headphones work, so clearly your sound card is fine.
1. Ensure an incorrect version of OS X is not installed. If one is, then reinstall or erase/install after backing up your data.
2. Remove any external audio devices from USB, firewire, etc.
3. Open Sys Prefs > Sound > Output
If Internal Speakers is listed, select it and test again.
If Digital Out is listed, confirm again that all external audio devices and cables have been removed.
If mute is selected, unselect it.
If the volume slider is low, raise the volume.
If the above simply doesn't fix it, the issue may be a corrupted plist. Apple Support might be able to help troubleshoot the issue further, per the last step of TS1574.
I hope it gets resolved for you. Good luck.
