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.

Macbook Pro Freezes At Startup after installing ram

Hey guys, hopefully some one has more knowledge than i do on this
my macbook pro came with 4gb of ram and so i have decided to upgrade to 8gb. the manual and the computer itself sais i can upgrade to 8 gb no problem, (2x4gb) so i rodered the ram, and i have quadruple checked it isz the right ram. upon putting both 4gb modules in, it would start up, and the little loading wheel under the apple logo would spin, n spin, then stop. so, i took the ram out, i put in one old module and one new module, and it works, the computer registers having 6gb of ram. i mizxed up all the modules and both new ram sticks work, and both ram ports work, the computer will show me which is which in the about this mac thing, but it just wont except the full 8gb!!!
i did not touch the gold metal on any ram sticks, i did touch metal to get rid of sttic, i have done the p ram reset, (but i didnt need to do it with the 6gb installed) and i have no idea what else to do :?

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:

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.

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.

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.

Freeze during startup after SW update from 10.4 - 10.4.8

After updating to 10.4.8, my machine would freeze during startup (at the gray screen with the apple and spinner) and give me the "Please restart your computer" message in a few languages.
I thought it might be a RAM issue, so I removed all third party RAM - same problem.
I replaced all of the RAM with RAM from another G5 that I know worked - same problem
I moved the HD from my G5 to another G5 that was working - same problem (I believe that eliminates the motherboard and any other components from being the problem).
I thought that the HD might be bad, so I replaced it with a brand new SATA drive, installed 10.4 and it worked perfectly, ran all of the SW updates (including the combined 10.4.8 update) and I get the same freezing again when I reboot.
Any suggestions are appriciated!

Hi Joe,
Welcome to the only place where you can get friendly advice.
Ok have you tried starting up from the installer / restore CD that came with the mac and run disk utility??
Try hardware test doing the extended test in a loop to try and find the base of the Kernel panic (thats what the "you need to restart your computer" image indicates)
For info and guidance on Kernel panics see:
http://docs.info.apple.com/article.html?artnum=106227
and trouble shooting info:
http://docs.info.apple.com/article.html?artnum=25392
for extensive advice on solving the kernel panics see:
http://www.thexlab.com/faqs/kernelpanics.html
Worst case senario it could be the G5 processors, make sure you have applecare; just in case it gets expensive!!

Macbook Pro cannot start properly after Yosemite v10.10.3 update

Hello,
I have a serious concern with my MacBook pro 13Inch Retina. After the recent update to Yosemite v10.10.3 on 18 April, whenever I start my Mac book, the Apple icon will not show up immediately as usual just black page. It only appear after I press the power bottom again( or sometimes by luck a 5 mins wait) then the icon will appear and system turns into login page. This is not normal!
Anyone please help! I am not sure if I were the only one experiencing this or this is a bug come with the recent update.
Thanks!

Repair the Hard Drive and Permissions - Yosemite, Mavericks, Mountain Lion or Lion
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
When the recovery menu appears select Disk Utility and press the Continue button. After Disk Utility loads select the Macintosh HD entry from the the left side list. Click on the First Aid tab, then click on the Repair Disk button. If Disk Utility 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 Disk Utility and return to the main menu. Select Restart from the Apple menu.
Now, download and install the OS X Yosemite 10.10.3 Combo Update.

Macbook air 2013 freezing at startup after yosemite update

My 2013 Mb air has started freezing at startup. performing a safe reboot seemed to help, but once I restarted immediately after rebooting it froze again. A second try apears to have done the trick, however, now my volume is completely off and non-responsive, and Safari is not really working. This is one day after updating to Yosemite.

same for my MBA 2013 model...its taking very long to show me the password box after clicking the username.....it happens everytime i restart...once it starts, everything is fine...if i had to force restart it (it froze couple of times), it takes really long to reboot...and again login is a big deal...any ideas/tips ???

Late 2011 MacBook Pro can't boot after Yosemite install

After installing Yosemite on this late 2011 MacBook Pro it stops about a third of the way into booting up. It displays a null sign. I can boot into recovery disk, or external HD (I don't have a backup of this system, but can boot from my MacBook Air's clone) if I use option-R or just option at startup. It won't go into Safe Mode. From the ext HD I have reinstalled Yosemite on the MBP, but it still freezes mid-boot. Disk Utility repair permissions, repair HD, zap PRAM, SMC, I've tried all of these (from reading advice here, and PM from Ogelthorpe). I have copied the Etre Report below. Suggestions?

Drive Partition and Format
1. 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.
If you are preparing an external or a non-startup drive, then open Disk Utility in your Utilities folder.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed.
4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
5. Set the format type to Mac OS Extended (Journaled.) Click on the Security button, check the button for Zero Data and click on OK to return to the Erase window.
6. Click on the Erase button. The format process can take up to several hours depending upon the drive size.
7. Quit DU when it is finished and return to the installer. Install Snow Leopard. Download and install Mac OS X 10.6.8 Update Combo v1.1.

Macbook pro stalls during startup

My macbook pro with Yosemite stalls during startup. I've tried Command R and ran disk utility. The disk is ok. I've zapped the RAM but it still stalls about 25% of the way through the startup process.

Reinstalling OS X 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.
Reinstalling OS X Without Erasing the Drive
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 and press the Continue button. After Disk Utility loads select the Macintosh HD entry from the the left side list. Click on the First Aid tab, then click on the Repair Disk button. If Disk Utility 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 Disk Utility and return to the main menu.
Reinstall OS X: Select Reinstall OS X 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 won't startup after 10.9.1 update

Early 2013 Macbook Pro 13" retina running Mavericks.
Installed the 10.9.1 update and left it to do that and when I returned it had restarted in Bootcamp in Windows 8.1
Requested in Windows that it startup in OSX. On starting up OSX a message came up saying there was a problem starting.
It tries to startup a couple of times then a circle with a line though it comes up and it goes no further.
Tried booting into recovery mode to check permissions etc. in disc utility but that's not coming up either.
Any suggestions on what else to try?

Chose startup disk manually:
Hold the Command button during startup, then select your macintosh partition.
Reset the nvram:
Turn on your mac while holding Command-Option-P-R until the chime sounds for the second time.
Safe boot:
Boot while holding down the RIGHT shift button.
If you have a Time Machine, you can use that to restore.
Reinstall via recovery:
Hold down Command-R during boot, then hit reinstall in the menu.
Other than that, you'll have to go to a Genius Bar.
Hope this helps!

My late 2011 Macbook Pro is running slow after Yosemite upgrade

Hello everyone! I'm a little desperate as this is my working computer and I'm not sure what else to do. I took it to a mac technician and they did a clean intall, checked my memory cards and said there should be no problem.
I get it home, install the basics programs I need for work- Adobe, Chrome, Firefox, iWorks. My computer is still running very slow. The start up is slow, the internet is very slow.
Here's my EtreCheck report. I hope maybe one of you can shine some light on the issue. Thank you in advance for all the help.
Problem description:
My computer is running very slow. Even the browser when switching between tabs will show a blank page for a few seconds before showing the actual page. It was rebooted and nothing. This problem started after upgrading to Yosemite.

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!

17" MacBook Pro will not startup after software update & shutdown

Last night I powered off (shutdown) my MacBook Pro (usually I leave it sleeping). It kindly reminded me I had updates to install. I said OK install them. I didn't check to see what they were, but I believe it was just the camera raw update. I also told it to shutdown after the update.
This morning the computer was off, so far so good.
Press the power button ... nothing. no chime, no diskdrive, blank screen....
Battery level is good, power adapter good with green light.
I have command control power buttoned. reset smu. cannot reset pmu as far as I know as that happens later in the startup procedure? post chime?
I pulled the power and battery and let it sit all day, still nothing.
Any ideas on the sudden failure. The software update seems unrelated, but somewhere in the back of my head I remember hearing about some problem with a camera raw update?
It's a 1st generation 17" MBP. TIA

Just to clarify the symptoms:
Good power adapter, green light on mag-safe when plugged into machine. Good battery(s) have two, both charged.
Press power button and nothing happens, no drive spin up, no noises, no chimes, no screen backlight (even with black screen) etc.
tried control-command power button for 3+ seconds, naughta.
tried pulling power and battery, then hold power for 5 sec. recconect bat and power, naughta.
tried removing all power for 8+ hrs, naughta.
It doesn't seem to be getting power to any components on -power button down -
So, I am guessing here but seems like:
a. Power button/connectors.
B. Firmware issue as last time it was run a software update (unknown) was installed.
C. Logic board?
D. As there is a green light on the power adapter I expect it is not the Left I/O subassembly board?
Are there any other power supply boards that may be involved, or are all of those components on the main board in this machine? Is the power button part of the keyboard assembly?
TIA.
