Try resetting the Intel-based Macs: Resetting the System Management Controller (SMC) and Resetting your Mac's PRAM and NVRAM. Then:
Reinstall OS X without erasing the drive
Do the following:
1. Repair the Hard Drive and Permissions
Boot from your Snow Leopard Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. 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 installer.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
2. Reinstall Snow Leopard
If the drive is OK then quit DU and return to the installer. Proceed with reinstalling OS X. Note that the Snow Leopard installer will not erase your drive or disturb your files. After installing a fresh copy of OS X the installer will move your Home folder, third-party applications, support items, and network preferences into the newly installed system.
Download and install the Combo Updater for the version you prefer from support.apple.com/downloads/.

Why my mac pro dont start stay download and turn back off

My mac pro dont start stay download and turn back off

Thisvis not MacBook territory but.... same applies - bootable backup clone of your system and iot should never crash or freeze but if it does then consider using Recovery Mode immediately and Safe Boot Mode.
Your drive and its directory cannot be repaired without doing more.

Tried starting holding option command P and R key and didnt work either. Starting to think I have lost all my data inside

Try a SMC reset.

It might be helpful if you indicated the exact model/year of your MBP. Are you running Lion OSX?
Ciao.

HT4796 Hi, I've just bought a new Macbook Pro and started migrating from PC but the remaining time is about 70 hours long, I just wanted to know if that timing is normal and if not, does leaving running my MacBook that time can affect it?

70 hours... no, it's not normal but it can't hurt your Mac to be running for that amount of time.
Try this support article > OS X Mavericks: Transfer your info from a PC

How long does it take for a macbook pro to start , mine takes about 1 mn is this normal?

Details of your specific hardware/software setup are in play, of course.
But, yes, that sounds normal.

Macbook pro doent start

macbook pro doesnt start, comes with question mark. I do not have the recovery disc anymore.

Your computer can't find a boot drive. It's possible that your hard drive is dead/dying or that your MBP has simply 'forgotten' your startup drive. Try rebooting while holding down the option key and see if your internal drive shows up as an option to boot from.
You really need to have a copy of the installation disc(s) that came with your MBP. You can order a set by calling Apple - I don't know the number, but there's a store in Amserdam - http://www.apple.com/nl/retail/amsterdam/.

My MacBook Pro just started to run very slow, what can I do to fix it?

My MacBook Pro just started to run very slow, what can I do to fix it?

First, back up all data immediately, as your boot drive might be failing.
There are a few other possible causes of generalized slow performance that you can rule out easily.
Reset the System Management Controller.
If you have many image or video files on the Desktop with preview icons, move them to another folder.
If applicable, uncheck all boxes in the iCloud preference pane.
Disconnect all non-essential wired peripherals and remove aftermarket expansion cards, if any.
Check your keychains in Keychain Access for excessively duplicated items.
Otherwise, take the steps below when you notice the slowdown.
Step 1
Launch the Activity Monitor application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Activity Monitor in the icon grid.
Select the CPU tab of the Activity Monitor window.
Select All Processes from the menu in the toolbar, if not already selected.
Click the heading of the % CPU column in the process table to sort the entries by CPU usage. You may have to click it twice to get the highest value at the top. What is it, and what is the process? Also post the values for % User, % System, and % Idle at the bottom of the window.
Select the System Memory tab. What values are shown in the bottom part of the window for Page outs and Swap used?
Next, select the Disk Activity tab. Post the approximate values shown for Reads in/sec and Writes out/sec (not Reads in and Writes out.)
Step 2
If you have more than one user account, you must be logged in as an administrator to carry out this step.
Launch the Console application in the same way you launched Activity Monitor. Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left. If you don't see that menu, select
View ▹ Show Log List
from the menu bar.
Select the 50 or so most recent entries in the log. Copy them to the Clipboard (command-C). Paste into a reply to this message (command-V). You're looking for entries at the end of the log, not at the beginning.
When posting a log extract, be selective. Don't post more than is requested.
Please do not indiscriminately dump thousands of lines from the log into this discussion.
Important: Some personal information, such as your name, may appear in the log. Anonymize before posting. That should be easy to do if your extract is not too long.

My macbook pro has started running slowly! Any ideas?

My macbook pro has started running slowly. Particularly the internet (firefox and safari). I have tried repairing the disk / verifying the disk and the permissions via Disk Utility, and have also tried uninstalling and re-installing firefox, and updating the software (all up to date). None of this has helped.
The old Dell laptop we have is running faster than my mac!
I also have Parallels Desktop Installed with Windows 7, although this has never caused a problem in the past...
I am running with Mac OS X, Version 10.6.8, processor 2.66Ghz Intel Core Duo, and 4GB memory (it's normally lightning fast!).
Any ideas would be much appreciated.
Thanks.

This is a known problem with Parallels and the recent update for 10.6.8. You do not need to actually have Parallels running to experience the problem and there is nothing in Activity Monitor that would indicate the issue is related to Parallels. You can find the explanation on Parallels site. They have put out an update to correct the problem:

Why is it taking forever for my MacBook pro to start up?

It is taking forever for my MacBook pro to start up. It's been on the screen with the grey apple and the spinning icon for about 20 minutes now. I tried holding down the shift button when powering up to reboot in safe mood but that is taking forever as well. Any suggestions?

My early 2011 Macbook Pro on start up has wifi, but drops it soon after and never comes back, AHT shows nothing wrong. Multiple wifi's tried and same on all.

My early 2011 Macbook Pro on start up has wifi, but drops it soon after and never comes back, AHT shows nothing wrong. Multiple wifi's tried and same on all. I have also re-installed OSX from scratch and still happens.

I have the same problem. I have a white macbook 2010, with mavericks os. I just found my mac not powering on and then I tried to run it on safe mode by holding the shift button but it will turn off seconds after I let go of the shift button. I am able to access the desktop and use it while holding the shift button the whole time. It's a bit slower than before but I figured maybe it's because of holding down shift button.
I went to the Apple Store to have them look at my mac and I was told it's a failed hard disk. I wasn't told why he was able to conclude that a failed hard disk is causing the problem, I was just told to get a replacement. But the thing is when I ran Disk Utility it says, "disk appears to be okay." So I also feel like it's possible it's not a hard disk issue because it's also the first time it happened. My mac was working perfectly fine before all this.
Do you know anything else that could cause this problem? Were you able to find out what's wrong?
Thanks.

My macbook pro (2011) starts up very slow and has other startup resolution

I have two problems:
My Macbook pro (Lion) starts up very slow. Many things seem to happen during startup. The screen goes small, blue, back and many times the loginscreen is coming up in a lower resolution. When I do a Pram reset it starts up with the correct resolution but after a couple of startups it goes back to 800x600 resolution (I guess). When I Log in the resolution is ok so only the login screen is a lower resolution.
Can anybody tell me what can be wrong here?
And if there is a solution beyond resetting the PRAM?

Hello,
For the screen resloution problem:
I don't know if you have solved your problem yet but i had the same exact problem this morning and was able to find the solution and fix it.
All you have to do is safe-boot your machine (hold shift key during restarting/booting) and after the next restart it should be fine.
Hope it helps.

MacBook Pro Freezes starting up, What do I do?

MacBook Pro Freezes starting up since I upgraded to Yosemite from Mavericks... What do I do?

Hi Ralph, thanx for your quick answer...
The thing is that I could get tothe login screen but once i got my password introduced, the status bar froze like at 45% and then nothing else happened.
I decided to get back to mavericks, which I did but after several hours installing/downloading from a bootable pendrive that I have with Mavericks on it, when the time came to install an error kept occurring so I just had to take out the hard drive, save my data and swipe all of it out so I could perform a clean installation with a formatted disk, which due to little time left at the office, will perform today when I get there in the morning. Thank you again, I'll write againwhen I finish installing Yosemite, hopefully without trouble.

MacBook Pro not starting up......

Hi,
My husband has recently bought a new MacBook Pro which was working fine until one day he went to turn it on and it does nothing but some up with a blue screen, the apple sign and then after a while a small circle with a line through it comes up (similar to a stop sign) and it does nothing else.
Does anyone know what could be wrong with it? He hadn't done any installing or updates and said it was absolutely fine before it stopped working.
Any help would be greatly appreciated, and where possible, a clean install avoided!!!
Many Thanks
Sleepy

it basically sounds like its just not recognizing the HD as the start up disk. can be a simple as some how the setting for it got messed up or as worse as the HD is corrupt.
along with the other suggestions (if those dont work or you have issues) try to boot with another machine using that HD as its start drive (use target disk mode on that, start it while holding T) and if that doesnt work you can probably expect the HD has some issue but you can still possibly access the info on it while using it it target disk mode to at least copy off the info to save it. i am actually waiting for a friend to get me an external drive so i can do that for her, her machine isnt not booting but might as well not be and you cant boot of her drive but i can at least access it

Bad System call. Macbook pro wont start up

Hello,
I seem to have come across a problem. I thought it happened after trying to install new software through X11. I restarted my macbook pro and received about 15 error messages all containing information about certain extensions not being installed properly. I remember one being about my 802.11 airport but I havnt altered anything to do with it.
When I turned my macbook off and on again I got a black screen with info about about bad system calls, throttling too quickly etc..
I noticed a number of people mentioning the i tunes update which I tried to install before it completely died and it wouldnt actually finish the update so i just force quit software updates. Now my machine doesnt do a thing: when I turn it on I receive the apple symbol with the spinning cog and eventually it goes back to the black screen with the bad system info.
I started in single user and tried fsck - fy and it said everything was ok. I tried to start in safe mode however when I turn my macbook pro on I dont hear the chime- therefore I dont seem to be able to enter safe mode.
If anybody can help ASAP it would be much appreciated- got lots of work that needs doing on it:)
cheers
Graeme
