My macbook pro won't boot with ram upgrade

Hello all I was given a legacy MacbookPRO  model ID 2,1 (A 1212 from the bottom of the computer)-
Its currently using 4 gigs from OWC 2sticks at 2gigs each-
It-groans and moans when I using Adobe stuff, mainly photoshop, dreamweaver, and illustrator-
the TLDR version of this saga is I wiped out google fu to find out it's possible to get up to 6gigs-
Tride that. #FAIL-
No boot. Just flashing sleep light.
What can do to get enough more pep out of this legacy laptop?
Mor pep meens having the applications I need to kick butt and chew buble gum for finishing off my CIS and Webdesign certificits, and when not doing that  Getting my WoW on.

#FAIL
while not gospel: http://www.ifixit.com/Answers/View/94128/Upgrading+Memory+to+6Gb+RAM
So: Either this POS has the defect as mentioned before or the ram I got was deffective
The POS I got has has the Radeon X1600- wich  at least in so far a Crusair and OWC are concerned would work with macbooks

  • MacBook Pro won't boot after ram upgrade...

    Hey everybody! Hope everyone is having a great Christmas! I got a 16gb ram upgrade for my 2012 MacBook Pro 15 today and I am having some trouble with the upgrade. Its an odd problem. I installed the two 8gb sticks no problem, but when I try and boot into OS X the machine shows the apple logo with the spinning wheel underneath, and then it just shuts itself off. I don't know what the problem is. The machine boots fine into my Windows 7 partition, and registers both sticks of ram. OS X restore also boots no problem and lets me reinstall OS X, which is what I am doing currently. IDK if this is just because of a hardare change or what. The ram I installed is Adata pc3 12800 1600mhz ram, so it should be supported.

    Replace the Ram, buy from OWC or Crucial, buy the Ram Apple recommend, don't rely on "it should work"

  • Macbook Pro won't boot with external HDD plugged

    I have a weird problem. My late 2008 Macbook Pro won't start with external HDD plugged either FW or USB... The screen stays white until I unplug it and then the Apple logo is there.
    Anyone know any solution for this? Or anyone have the same problem

    yeah I had the exact same issue with one of my 750GB externals too. I just left it for a while (about an hour or so) and it was fine..
    I believe its so slow because the system is indexing the drive, which can be a very slow process if the drive is big, has a complex folder-hierarchy, and/or is fragmented.
    Does the hard-drive appear quite quickly in Finder once OS X has started up? if its slow it may confirm what I've just said.

  • Macbook pro won't boot with two new 4GB RAM sticks.

    I have a mid 2010 Macbook Pro. It came with two 2GB RAM sticks. After downloading Lion, my computer started to get sluggish so I thought I would upgrade the ram. I bought two 4GB Corsair RAM sticks and tried to install them. My computer will boot up if I install one of the new 4GB sticks and leave an old 2GB stick; but it won't boot with both of the new 4GB sticks. Any ideas?

    Unless I misread your reply, that is not quite accurate.
    Late 2008 Macbooks uses DDR3 1066MHz 204 PIN.
    Late 2011 Macbooks uses DDR3 1333MHz 204 PIN.
    Late 2012 Macbooks uses DDR3 1600MHz 204 PIN.

  • MacBook Pro won't boot with new hard drive, but a different MacBook Pro will

    So here are the details. My friend and I both have 13-inch Mid 2010 MacBook Pro's. Same processor and specs since they were purchased at the same time, but originally had 250 GB hard drives. His hard drive failed and needed a new one. Put a 500 GB Seagate Momentus 5400.6 in his computer, and tried using a flash drive with "Install OS X Mavericks" on it to install Mavericks on his new hard drive. No matter what, it wouldn't install. I finally was able to install OS X 10.9.4 on it by connecting the new hard drive to my computer with a USB hard drive enclosure. I put the hard drive back inside his computer and it wouldn't boot (stuck on the gray screen with apple logo and a spinning wheel). I then attached to the hard drive to his computer externally with the USB enclosure, and then it booted and worked perfectly.
    So, it seemed like the problem was with something inside his computer, but then I switched our drives, and that doesn't seem to be the case anymore. I put my original hard drive into his computer, and his new hard drive into my computer, and they both booted and worked perfectly, so I have no idea why his computer will not boot with the new hard drive internally.
    To summarize, his computer boots with: 1) new hard drive connected externally (won't work if it's internal), and 2) my hard drive internally
    but my computer boots with: 1) new hard drive connected externally AND internally, and 2) my hard drive internally.
    Both hard drives have OS X 10.9.4 installed
    If anyone has any idea what's causing this and how to make his computer work with the new hard drive internally that would be greatly appreciated.

    So after switching the internal SATA cables from each computer, now we have
    His computer, with my SATA cable:
    1) Worked with every hard drive!
    My computer, with his SATA cable:
    1) Works with 1 TB Toshiba hard drive
    2) Works with 500 GB Seagate hard drive
    3) Works with my original hard drive
    4) Flashing folder with question mark with his old hard drive
    So it turns out you were right! Definitely had something to do with the SATA cables. But it's still strange that mine was able to boot with all the hard drives except the one that was originally in his. So it seems like it was some combination of his SATA cable and something else, since when his SATA cable was in his computer only 1 hard drive (my original) worked, and when it was in my computer, 3 hard drives worked. But at least its working, and I'm just gonna keep our SATA cables switched since that seems to work out fine

  • Macbook Pro is Not Booting After RAM Upgrade

    Hi,
    I just upgraded the RAM in my MacBook Pro running Mountain Lion from 4gb to 8gb (Using the memory that the guy at Fry's recommended). It has been stuck on the Apple logo for about 20 minutes after the upgrade, even after I made sure that the RAM was seated properly. Is it normal for it to take this long to boot after a RAM upgrade?

    I installed 8gb (2 X4gb) and it has a maximum of 8gb. I have determined that it was just bad RAM, so I will return it as soon as I can.
    Thanks.

  • Macbook Pro won't boot after Yosemite upgrade

    I downloaded Yosemite this evening, but the installation never finished. When I get past the login screen, a loading bar will half load before the computer shuts down. I tried command option p r without success, holding the option key down while starting only gives me the option of my main drive and it doesn't work. I tried holding down command r during start, but that doesn't do anything either. Any suggestions would be appriciated.

    Reinstall Lion, Mountain Lion, Mavericks or Yosemite without erasing 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
    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 then click on the Repair Permissions button. When the process is completed, then quit DU and return to the main menu.
    Reinstall Lion, Mountain Lion, Mavericks, or Yosemite
    OS X Yosemite- Reinstall OS X
    OS X Mavericks- Reinstall OS X
    OS X Mountain Lion- Reinstall OS X
    OS X Lion- Reinstall Mac OS X
         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 boot, stuck on white apple screen

    Noticed today, that my macbook pro won't boot . It gets to the white apple screen with the spinner under the apple logo. It stays like this for a long time without doing anything except spinning.
    I've powered down and tried to boot up several times.
    I have boot camp and windows on my mac and when the white screen appears, I can press Option to bring up which hard drive and the Windows partition will load without any problems.

    Exacty what happens when you try to boot up from the disc that came with your computer?  Are you holding down the c key?  Have you tried holding down the "option key?"  Are you able to run the Hardware Test - Intel-based Macs: Using Apple Hardware Test
    Shut down your computer and disconnect all peripherals (keyboard & mouse if pertinent) from your computer.  Now reboot.
    If the Mac starts up normally, shut it down again and then plug in one of the peripherals (keyboard or mouse first) and start up your computer again.  If it does so successfully repeat the process, adding one peripheral at a time until your Mac acts up.  At that point, disconnect the last peripheral you added, reboot your Mac and search the peripheral vendor's website for an updated driver. 
    If no driver exists or the problem remain after installing the new driver, try a different cable or a different port on your Mac.
    If none of the above works, again disconnect all peripherals from your Mac, hold down the "shift" key to start up in "Safe Boot" mode. 
    If the Mac starts up correctly, restart without pressing the "shift" key.
    If your computer still does not start up properly, shut it down and restart it while holding down the Apple+Option-P-R keys; keep holding "all 4 keys" down until you hear the startup sound "twice."
    If none of the above work Disconnect all peripherals from your computer. Boot from your install disc & run Repair Disk from the utility menu. To use the Install Mac OS X disc, insert the disc, and restart your computer while holding down the C key as it starts up.
    Select your language.
    Once on the desktop, select Utility in the menu bar.
    Select Disk Utility.
    Select the disk or volume in the list of disks and volumes, and then click First Aid.
    Click Repair Disk.
    (If Disk Utility cannot repair, you will need a stronger utility (3rd party) - Diskwarrior or Techtool PRO)
    Restart your computer when done.
    Repair permissions after you reach the desktop-http://docs.info.apple.com/article.html?artnum=25751 and restart your computer.
    Remove any 3rd party ram.
    Reinstall Lion - This will install a "fresh" copy of Lion without archiving old system files but leaves the rest of your files in place.
    If your computer is still under warranty or you have Apple Care, take full advantage of it by letting tech support deal with your problems.  It's what you're paying them for.
    Out of warranty - take the computer to an Apple store or an AASP.  Whichever is more convenient for you.

  • My MacBook Pro won't boot and apparently my HDD is locked

    My MacBook Pro won't boot up. And it's says my HDD is locked when i try and reinstall OS. Help me please good people.

    you want to check how many threads with same question first, and look in
    Mac OS version forum that you have; and the notebook MacBook instead of the workstation forum for Mac Pro (non-laptop)
    Not a lot of detail to go by with "won't boot" though.

  • Macbook pro won't boot - how do I retrieve emails?

    Hey guys
    I've got a common problem that my Macbook pro won't boot. Sometimes I get stuck on the grey screen with spinning wheel, sometimes on the blue screen with spinning wheel
    I've scoured the internet on another machine and tried every trick I can find with the MacBook Pro including
    Disk / Permissions repair from install disk (says the HD is fine)
    PRAM
    Single User
    Soft
    It seems like my only option at the moment is an Install and Archive. I can mount the MacBook Pro on another machine with a firewire and remove files and backed up a lot on a hard drive before it died
    What I am worried about is how to retrieve some emails from the machine that only exist locally because I have deleted them from the server
    Is there a way of doing that?
    Would Migration Assistant work?
    If anyone could help me with this or suggest any other methods for bring my machine out of a coma I'd really appreciate it
    d

    Try a different adapter. If you don't have access to a known-good adapter any other way, make a Genius Bar appointment at an Apple Store.

  • MacBook pro won't boot up Keeps turning off

    MacBook pro won't boot up.  When power button pressed the white screen w apple comes on w progress bar but shuts off before bar completed. If I move cursor or hit buttons it boots but will turn off if cursor stops Moving or stop pushing buttons.  Just started happening.   Ran hardware test and all shows ok.  Any ideas??

    Thanks for all the help; however, I still continue to have problems booting off of any other media.
    I've tried the Apple CD w/ no success - I made an image of the apple cd and restored it to a USB drive, and it won't boot. I've tested both methods on another mac, and both options boot fine.
    I'm going with my last restort here and am going to install OSX on a portable USB HD, and try to boot off of that (no clue if it will work given the outcomes of the other things I have tried). From there I'm going to backup the HD, and try DW as suggested.
    Any thoughts as to why the mac refuses to boot off of any other media? It always boots halfway and then tells me I need to shutdown my mac.
    Thanks again,

  • Macbook pro won't boot after installing update 10.9.3

    macbook pro won't boot after installing update 10.9.3

    Please read this whole message before doing anything.
    This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
    The purpose of the test is to determine whether the problem is caused by third-party software that loads 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.
    Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode.
    Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a Fusion Drive or 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 login 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 the test.

  • MacBook Pro won't boot after trying to install 10.7.3 update. Start up stalls at Apple logo and spinning gear.

    MacBook Pro won't boot after trying to install 10.7.3 update. Start up stalls at Apple logo and spinning gear. Computer won't even start in safe mode.

    My daughter's MacBook Pro was doing exactly the same thing.  I don't know if it had anything to do with the latest update.  She called me about a week ago saying that her MacBook began running slower by the day .  She then called me Friday and told me that it wouldn't get past the gray screen and the gear just kept on spinning.  I did everything I could over the phone including Safe mode which it wouldn't go into and thought maybe it was the hard drive.  She took it to the Apple store.  Originally, they also thought it was the hard drive.  It ended up being a corrupted operating system (Lion).  Apple genius simply re-installed Lion and she's back up and running.  Good thing she backed up right before it crapped out.  She'll be restoring everything tonight.  Don't know if re-installing Lion will help your situation, but it did the trick for my daughter.

  • My 2007 MacBook pro won't boot up beyond a White screen any ideas what to do?

    My 2007 MacBook pro won't boot up beyond a White screen any ideas what to do?

    Odd how this hasn't been archived yet.
    I'm getting the same thing with my Macbook, but can't boot past the white screen. An Apple store in KS suggested I needed a new hard drive, but I've already put two in there and it's still doing the same thing. I really don't want to buy another motherboard like I had to a couple of years ago.
    My choices are either buy a cheap drive to boot from and remove the current one to put into an external case, or save the money by not buying a new motherboard and putting it as a down payment toward a Mac mini.
