HT1237 My MacBook Pro freezes during startup. It shut itself down a few days ago and won't restart since then.

Forgot to mention, downloading a firmware update is not possible unless one has another way of starting the machine. (I'm posting this on my iPad.)

Try resetting SMC and NVRAM:

Return that RAM and buy either the Crucial ram (http://www.crucial.com) for your system or buy from OWC (http://www.macsales.com). I've used Cruical ram in many systems over the years with no issues, and have bought Samsung (factory fill) from OWC with no issues either.

My MacBook pro freezes during start up after 30 secs. Any ideas?

My MacBook pro freezes during startup while the logo is still showing and the moving circle stops after about 30 seconds. Any ideas please?

On my Mac that DSMOS message appears about 20 seconds into the boot process. Booting finishes about 30 seconds after that.
Do those letters "v" really appear on the screen?
Unfortunately, if those are the last messages on the screen, I see nothing there that explains the hang. The next message I see after the DSMOS message is one about an AirPort daemon, although I'm not sure I understand any connection there might be between that and your hang.
Since you don't have a system restore disc you won't be able to do the next thing I was going to suggest, which is to run the diagnostics that came with that Mac. If you have an OS X 10.6 installation disc, you could try reinstalling OS X over the top of what's on it now. Right after that finishes use Software Update to apply any missing OS X updates, or download and install the "combo" updater for the version of OS X 10.6 that you want. If that Mac has a software problem doing that might help.

MacBook Pro freezes during start up and safe boot

MacBook Pro freezes during start up and will not start in safe boot in recovery, it goes back to apple screen with spinning gear

Stinkster,
does your MacBook Pro have a removable battery? If so, then it originally came with grey installation DVDs. If it doesn’t have a removable battery, look on the bottom of your MacBook Pro for its serial number (it’s etched there in tiny print). If its serial number has eleven characters, write down the last three of them; if it has twelve, write down the last four. Include the three or four characters in your reply; they can determine which model MacBook Pro you have, and the model will determine whether it originally came with grey installation DVDs or not.
If your MacBook Pro did originally come with grey installation DVDs, then you’re going to need to find them (or buy a replacement pair from Apple or iFixit) to reïnstall Mac OS X on your current hard drive, or to install it on a replacement hard drive.

My 13" MacBook Pro freezes at startup

While using Firefox, my Macbook pro frooze about 2 days ago. The screen was only showing the multi-colour spinning circle.
Pressed [Command + Option + Esc] to force quit. No response
Pressed Power Button for 10 sec.Power OFF
Again Pressed Power Button, the MacBook Pro freezes at startup, the MAC makes the startup music, enters a white Screen and is stuck there. There is a light clicking noise continously heard.
Followed instructions to RESET SMC.
1. Power OFF.
2. Press [Shift + CNT + OPT + Power Key] and release at same time.
3. Power ON.
There was no response.
Attempted multiple times to switch-ON and OFF MAC-Book. No response
Attempted RESET SMC multiple times. No response.
Then suddenly when I gave up, it unfreeze after 15 minutes and enters the login screen.
Did a normal shut-down and power up. It was OK.
Then, ran the Firefox in debug mode and disabled the plug-ins.
It was stable for a 2 hours.
Then again, got the spinning colour circle.
So, took it to the service center last afternoon here at North Point, Hong Kong. The engineer there instructed me to backup the hard-disk and recover the CD.
Brough the machine back to my home.
Since the spinning colour circle would not stop, powered OFF the device.
On POWER ON, the screen freeze. Just like the first time.
Tried RESET SMC, Nor esult. Left the device power-on for an hour. No result.
Then, inserted the recovery CD. Powered OFF the Macbook Pro. Powered ON and pressed "C" immediately. No response. The CD is now stuck inside the MACBook Pro.
Still have the white Screen at Power-On.

Reinstalling Lion/Mountain Lion Without Erasing the Drive
Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the 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.
Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main 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.
Reinstall Lion/Mountain Lion: Select Reinstall Lion/Mountain Lion 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.

MacBook Pro freezes during installation of 10.6.8 supplement

Ran Software Update to install the 10.6.8 supplemental update on my 15 inch MacBook Pro (late 2006), which already had 10.6.8 installed (and the 2 GB factory RAM).
After restart, the computer hung at the gray screen with apple logo and spinning cog.
After at least 15 minutes - probably more, maybe as long as 30 minutes - I forced shut down with the power button, then powered up. Same result. Tried a couple of times more, same result.
A few days ago, I ran most of Tech Tool Pro's diagnostics and optimizations successfully, including rebuilding directories, de-fragmenting files, optimizing disk space, repairing permissions, doing the full suite of regular tests except for disk scan. No problems. The computer has been running fine.
Any ideas?

Update: Booted into single-user mode, checked disk via fsck -f (had to force it), no problems found.
Booted with Snow Leopard installer CD and ran Disk Utlity - repaired permissions and repaired disk. No problems found. 'Macintosh HD appears to be OK'.
Tried booting again - still hanging. Will let it go longer this time, but I'm not hearing any disk activity...

Macbook Pro freezes during boot

Hi.
I have an issue with my brand new old Macbook Pro. The good old grey screen with the apple logo and spinning gear.. At first a "loading bar" shows up and disappears, then the spinning crap shows up. i've tried letting it sit for a couple of hours, but nothing happens.
I bought it just a few days ago, it's a 2007 model and my first Mac.
Well, to my problem.. I've tried the /sbin/fsck -fy command,and it just says
**Root file system
Executing fsck_hfsv(version deskdev_cmds-491.6~3).
** Checking journaled HFS Plus volume.
** Checking extents overflow file.
Invalid Sibling link
(4, 19038)
** Rebuilding catalog B-tree.
** The volume System could not be repaired.
***** FILE SYSTEM WAS MODIFIED *****
and then trying to reboot but it just keeps coming back.
I've also tried starting it in safe mode, but nothing happens..
Anyone have a solution for this one?
I might also add that i have never used a mac before, so i might need it explained as easy as possible.
And i might also ad, that i'm norwegian, so my apologies for any bad grammar.
Cheeers - Fredrik.

I called Apple support today, and i'm getting the disc shipped for free of charge
Just becaus the lady i talked to messed up. <3 gotta love it

My MacBook keeps freezing during startup

I got my MacBook Pro in 2012. Currently, it keeps freezing while I try to turn it on. I get the apple logo and the spinning wheel, and eventually it freezes. I've tried starting in safe mode and it froze. I've tried recovery, it "restarts due to a problem during start up" and then freezes again. When it freezes, there are little green pixels on the screen as well.
Any help is appreciated! Thanks!

MacBook Pro freezes during several different login pages?

I recently reformatted my laptop, and had a new hard drive installed on my 2008 MacBook Pro. I'm running mavericks.
I have had these freezes happen to me on several login pages. I know it happened when I tried to log into Skype, when I tried to pay my GCI bill (login page), and I think it also happened when. Tried to log into an MMA forum.
It's always during a log in page.
I know I recently installed 'shockwave' flash or something...before I just had 'flash' so maybe that is it?
Any help would be greatly appreciated.
