HT1270 Macbook pro wont start after changing memory...

Hi! I have a 13 inch mac book pro late 2010 and i just intalled the new ram sticks but its not starting up properly. It never leaves the white page with the gray apple and turning wheel... I bought the DDR3 pc3-10666  instead of pc3-8500... Is that why?
Please help!

"... I bought the DDR3 pc3-10666  instead of pc3-8500... Is that why?"
Please help!
Most likely, yes. Macs are quite fussy about RAM specs. Return the new RAM and purchase the correct type/size.
Maximum Memory     8.0 GB
Memory Slots     2 - 204-pin PC3-8500 (1066 MHz) DDR3 SO-DIMM

  • MacBook Pro wont start after 10.8.3 update

    So I tired installing the 10.8.3 update from the app store  and every time I did it I got the response that it wasn't downloaded properly, first on bad Internet at my house, then at school I used the really fast Internet and it was the same problem. Then I came here found that a bunch of people had the same problem, so I downloaded the combo update from apple.com from a recommendation by someone here
    Now its one big shitstorm, after taking a half hour to install on my MacBook Pro ( its a 13 inch i got last august so its brand new),  during the install I was on chrome and it kept freezing about 75% of the install complete I tried to shut every program running, that just froze the entire computer for about 5 minutes, let it finish and it said it needed to restart. It said that something couldn't close and it needed to be force quit, so I did that and let it restart.
    It turned off, and started the loading screen with the apple and the gear below it spinning, then it froze, a half hour later it didn't change, i shut it off by holding down the power button and tried to start it again now it will go until the screen with the apple and spinning gear comes and then it will just shut itself off after about 2 minutes, tried safe mode, the bar at the bottom will load about 40% then it shuts off,
    What do I do now, anything on my own? can i try and take it into the apple store or did I probably loose everything?

    It sounds like your internal drive is failing, or has failed. What backups do you have?

  • Intel imac wont start after changing permission

    intel imac wont start after i changed my hard drive permission to let me read and write, then i clicked apply to all enclosed files.i turned it off no problem. then it never started up again in os x. the grey screen with apple logo appears,then after a minute it restarts, and will keep doing that if i let it. i can start up in windows xp, but i dont know how to do anything in windows xp that will affect os x. i can use the hard drive in target mode, but i cant figure out how that can help me. i use a macbook to view target disk. ive spent hours looking through help and support. finally i do not have the os install disks. PLEASE HELP!

    My apologies for the inept instructions.
    Restart normally. Open Terminal in the Utilities folder. Paste the commands in the Terminal application to avoid typos:
    sudo su
    Press RETURN. Enter your admin password when prompted.  It will not be echoed to the screen. Press RETURN again. Now paste each of the following at the prompt and press RETURN after each.
    chown root:admin /Applications
    chmod 0775 /Applications
    chown root:admin /Library
    chmod 1775 /Library
    chown root:admin /System
    chmod 0775 /System
    chown root:admin /Users
    chmod 0775 /Users
    chmod -R -N /Applications
    chown -R :admin /Applications/*
    Again, my apologies.

  • Macbook Pro Wont Start Up After Update

    Hey All,
    I was in the middle of installing the most recent update for OSX when my computer froze completely. I shut it off by holding down the power button. Now, when I start it up, right after the apple, it goes to a screen with some script in the upper left hand corner, and a box in the middle with a picture of the power button telling me I need to restart. I've restarted it several times and it just keeps going back to that screen.
    I have booted it up from the install DVD and run disk repairs and verifications, as well as checking the system profiler and utility, and nothing seems worng. I've tried starting it up by choosing to start up from the folder and it still didnt work.
    If you've got any ideas, let me know. All your advice is appreciated.
    Thanks!
    Macbook Pro   Mac OS X (10.4.8)  

    I meant to say that the system would have been made unstable after the semi-complete update (if it was in the middle of replacing a crucial system file).
    An archive and install would replace all system files, so wouldn't hurt anything. You might have to reinstall any system-intrusive applications (Palm Hotsync springs to mind, if you have that) but it will certainly fix system corruption, if that is your issue.
    After the reinstall, if you encounter a complete freeze again, then I would definitely be suspicious of hardware. Possibly the original RAM, but it could be somewhere else in the system, such as the logic board. In those cases, you would have to go back to Apple for repair. (Your Macbook Pro, that is, not you.)

  • Installed new memory and Macbook Pro wont start.

    I bought a total of 8GB from PNY for my mid 2009 MacBook Pro (2.8GHz Intel Core 2 Duo).  I installed it and my macbook wont turn on.  When I press the power button it just beeps.  The LCD doesnt turn on.   I reinstalled it a few times to make sure that it is sitting correctly with no luck.  I reinstalled my old memory (2x2gb) and it works fine.  
    The new memory I bought is PNY  8GB (2x 4GB) Bual Channel DDR3 PC3-10666.  The package says that it is compatiable with 1333MHz and 1066MHz.  This is the listed memory on the PNY website for Mac laptops. 
    Am I using the worng type of memory?  I'm pretty sure my MacBook Pro can take 8GB...right?
    THANKS!

    One beep indicates no RAM installed. See http://support.apple.com/kb/HT1547.
    What happens when you reinstall the old original memory? Does the computer boot then?
    You might want to read the information at macsales.com (OWC). Certain models had to be updated to take additional memory.

  • Macbook pro wont start up after trying fsck -y (incorrect block count)

    my 2 months macbook pro won't start up after numerous attempts and ive tried fsck -y and it says "incorrect block count for file system.log (it should be 184 instead of 108) help please

    it just says start up disk full, its not full however it has at least 10Gb of space left.
    Your HD is full!  How large is your HD?  You should never let your hard drive get to where you have only 10-15% of space left.  You need to do some serious housekeeping.  However, you need to get to your desktop to do that. 
    Can you safe boot?  Read the threads over in the "More Like This" column over here.----------->

  • Macbook pro wont start up and stuck on a restart screen, after mountain lion installtion failure

    I tried installing Mountain Lion on my Macbook Pro and the installation failed because my "hardrive was damage and could not be repaired" it then told me to restart my computer and try again which i did. However i am unable to even get back to my desktop because the Macbook starts up and i get the grey Apple logo and then this screen appears:
    Instructing me to restart my computer, it has been stuck on this cycle for a few days now and i have no idea how to fix it.
    Any help would be much appreciated
    StephBeard

    StephBeard,
    if you still have your MacBook Pro’s original box, it can be found on one of the stickers on the box. If you don’t still have its box, it can be determined from your MacBook Pro’s serial number. If its serial number has eleven characters, write down the last three characters; if it has twelve characters, write down the last four. If you don’t have its box, please include in your reply those last three or four characters of its serial number.

  • Macbook pro wont start with 3 beeps

    hi
    Few months back I purchased a refurbished macbook pro (late 2012 model) with i7 processor and 8 GB ram. Now after 2 months I experienced problem with mac - it wont start with 3 beeps. I looked at different articles in net and found about no memory bank problem. I opened the back and changed slots and it seemed to fix the issue. However the issue was recurring few times and ram was changed. Again the issue seemed to have resurfaced. I tried with memtest in single user mode and RAM passes the tests.
    What else could be the issue around the macbook pro. Do you suggest taking it to local Apple store to get it checked?
    Thanks

    Test each module installed alone while switching slots (power down before switching and remove battery.) Do both modules work alone in each slot? If they do, then it would appear the memory is good as are the slots. So, something else is at play and only an Apple Store has the equipment to go further - make a Genius Appointment and take it in for service.

  • Macbook pro wont sleep after ram upgrade

    Hi,
    I have a 17" Macbook pro late 2011. I upgraded the ram from 8gb to 16gb last week and now I having trouble with sleep. When the laptop goes to sleep it always to seems to go into hibernation mode. When I open the lid I can only wake the computer by holding the power button for around 7 secs and then it does a restore from the HD. I've tried a PRAM + SMC reset. Also tested the ram and everything seems good. Below is the output from pm set, the console after hibernation restore (filtered for the word 'sleep') and the memtest. Any help would be appreciated.

    Hi fatlinesofcode,
    First of all, check out Apples article on the issue: OS X Yosemite: If your Mac won’t go to or stay in sleep If you find these steps don't help, try a few of the following
    A common cause for the Mac not sleeping is your printer. If there are queued jobs waiting to be printed, but your printer is switched off, for some reason you Mac just wont like it and simply will not go to sleep. System Preferences > Print and Scan > Open Print Queue
    Do you have an Ethernet Cable connected? People have reported in the past that removing their Ethernet allowed their Mac to sleep. This goes for other things you may have connected directly to your Mac also.
    Try heading into your Mac Preferences > Sharing and deselecting 'Internet Sharing' as well as 'Printer Sharing'.
    Also deselect Wake For Network Access by heading to System Preferences > Energy Saver > Power Adapter > Wake For Network Access.
    Energy Saver > Schedule > Startup or Wake - Uncheck.
    Alternatively, set your system preferences to Never Sleep, and put into Sleep manually: System Preferences > Energy Saver > Computer Sleep > Never.
    Good luck!

  • New Macbook Pro Wont turn after discharge

    Hello everyone,
    I just purchased my 3rd mac in the past 2 years, yeah that's how hooked I am, now windows free 99% and love it...
    My brand new macbook pro has a very annoying issue.. if I use it on battery power and it discharges completely I have to wait up to 15 minutes after connecting it to power to be able to turn it back on again. this is so frustrating as I am sometimes doing some work and have to get away from the computer for a few minutes.. If it discharges within that time and I come back to continue my work guess what.. I need to wait all this time even after connecting it to power to resume my work...
    Does anyone has the same problem? is this normal? I've searched google and haven't found the same problem on anyone else unless they are OK with that and just don't report it... I've never had this problem with any other laptop I own and is extremely annoying, my wife's macbook doesn't do that, if it discharges and goes to sleep you can just connect the magsafe adapter and it will come right back up.
    your comments will be greatly appreciated.

    My MBP has always come back immediately. So has my old iBook. I rarely discharge my battery completely, but will do so on occasion to calibrate it. But I have never had the problem you describe. My personal opinion is that the long delay is definitely not normal.
    Out of curiosity, next time your Mac shuts down like this, remove the battery and see if it will start up immediately. If it does, you could possibly have a faulty battery. If it still takes a lot of time to start up with the battery removed, there is something else wrong. I have never heard of anything quite like this. Since you didn't mention excessive heat, that wouldn't be a factor.
    Be sure you can reproduce the condition for the Apple genius. They have to see it to be able to do anything. Go in a bit early with a low battery and run it out in the store, so you can show them exactly what it is doing.
    Good luck!

  • My Macbook Pro wont boot after upgrading to SSD, A ? Mark on Folder appears

    Hello all,
    I just put in a new SSD into my mid 2012, 13" macbook pro. This is the exact SSD http://www.tigerdirect.com/applications/searchtools/item-details.asp?EdpNo=77394 89&tab=7&SRCCODE=WEBLET03ORDER&cm_mmc=Email-_-WebletMain-_-WEBLET03ORDER-_-Deals &utm_source=EML&utm_medium=main&utm_campaign=WEBLET03ORDER&cm_lm=noahbragg@cedar ville.edu
    I swapped out my optical drive and put in the SSD using this tutorial, http://www.ifixit.com/Guide/Installing+MacBook+Pro+13-Inch+Unibody+Mid+2012+Dual +Hard+Drive/13787 Everything seemed to go fine and i had no problems. But when I tried to start up the computer it stayed on a gray screen and a foler with a question mark on it, showed up blanking. I have looked all over for the internet for the answer, I have tried to reset the PRAM but it did nothing. I then tried to select what drive i wanted to boot from by holding the option key when i booted, but when the options came up, SSD or old harddrive did not come up as a way to boot up. There were some internet options to recover but they did not work.
    The SSD has nothing on it at this point, but my plan was to boot up using the original HD and then clone it over to the SSD, but ovbiously i cant even find the HD to boot to. I have seen that people are having troubles with booting to their SSD because of the new mavericks update, but i am just trying to boot to my original HD at this point.
    I also considered that maybe i possibly damaged the HD cables through static electricty, but when i searched more about it i learned that i should have heard snap or felt a jolt. None of these things happened when i installed the SSD. So i beleive that the hard drive or SSD are not broken in any way.
    Does anyone have any ideas or suggestions on how i can fix this? Need my computer very badly! thanks in advance.

    I also forgot to mention that after the first time i tried to boot, it went to the normal screen where it wanted me to put in my apple id password. but the loading wheel was just spinning the whole time. so i turned off the computer and tried again. thats when the question mark folder came up and kept coming up everytime after that.

  • Macbook pro wont start up and clicking sound

    Hi everyone
    My girlfriend spilled a coke on my computer couple days ago and my MBP shut down immediately. After all i took it to the apple store in Turkey and they said the problem is from the battery and they took it off and I started to use it on charge until i get a new battery. All day i used my macbook pro on charge without battery on it. Anyway I turned my computer off and next day press the power button to start it up and it didnt start up at all. Mag safe works OK. Charger light is green light and everytime i press the power button I hear a clicking sound and my built in cam light is lighting up. I couldnt figure it out what is wrong.. If you guys had any problem like this before or know the problem about it please share it with me.. I will be appreciated.. Thanks

    Problems related to liquid damage can manifest in different ways.
    It is hard to recover from liquid damage.
    Best.

    I freshly installed 10.5 leopard on my mbp and used it for 4 hours without issue.
    I did have a problem after installing ms office and deleted it and all preference files in same folder and worked ok after that. rebooted 3 times no problem.
    The buyer is freaking out saying its trashed and wont boot just has a flashing question mark, why would this be happening???
    Please help he's threatening me!

    Just replace the hard drive.
    If he lost data, look at data recovery services*:

    And in the future always recommend people backup important data frequently.
    If he still gives you death threats, call the police.

    It is very difficult to offer troubleshooting suggestions when the "os version" you are using is unknown as each os has their own troubleshooting solutions. 
    Please describe in detail all you have attempted to do in order to resolve the issue. 

  • Macbook Pro wont start up (Apple logo and spinning thing all I get)

    When I turn on my macbook pro I get the “tone” the Apple logo and the spinning thing but then the spinning thing just freezes up and does nothing for ever. I let it just site like that for 30 minutes then it just goes to black. It is plugged in so power is not an issue.
    I tried to boot up in safe mode and again I get the tone the logo then the bar to show the safe mode then the spinning thing then nothing. I did boot it up via firewire target mode and was able to see the hard drive and all my files on my imac so the hard drive works (I think).
    I do have the original install disk and am willing to start the computer fresh but have no idea how.
    So any suggestions???
    I also tried to turn on and run the repair mode I think that’s where I held down a key the screen went black and some commands ran then I typed somting like flvr - fv
    Thanks Brad

    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.
