External monitor problem macbook pro mid 2012

Hi everyone i have a really big problem.
I add a new SSD OWC extreme 6G and a Data Doubler with the original HDD of my macbook pro, i follow all the instructions, i install the latest OSX and install all my apps, till there everything went well and awesome, really fast and i was really happy, but when i connect my external monitor a Samsung SyncMadster T220M my macbook pro freeze but if i disconnet goes back to normal.
I shutdown and restart, connect again and the same.
If i shoutdown the mac and connect the monitor and then turn on, the OS does not start and stay loading.
SSD is the main Hard Drive and the standard HDD is the secondary for DATA
I follow almost all the advice on http://blog.alutam.com/2012/04/01/optimizing-macos-x-lion-for-ssd/ except the advice only for SSD because i have SSD+HDD
also i download the app Chameleon SSD Optimiser and turn on everything
I really need help!!!
PLEASE HELP!!!
I USE MY MACBOOK PRO FOR PRESENTATIONS!!!

I had never heard of "Chameleon SSD Optimiser" but I took a look at it after reading your message... I'm not sure that 'turning everything on' was a wise idea... enabling TRIM is fine, of course. I wouldn't think that 'Chameleon' options would have anything to do with your problem, however.
What sort of adapter are you using with your Samsung monitor? I would imagine that there is either a hardware fault with the adapter, or with either your Mac port or the port on the monitor.

  • Migration Assistant can't find External HD on MacBook Pro Mid-2012

    Hi, I have a MacBook Pro Mid-2012 running OS X Mountain Lion 10.8.2 and I am trying to use Migration Assistant to transfer Time Machine backups that are on my external hard drive, that I backed up from my old MacBook Mid-2010. The problem I am having is that Migration Assistant can't find my external hard drive. My MacBook Pro can find it when I plug it in (I see it in Finder), but Migration Assistant can't. Can anyone help or should I go to the Apple Store?  I need help with this problem as soon as possible.
    Thanks in advance,
    - Daniel 

    Since no one replied I figured out how to do it myself.
    1.) First I plugged in my external hard drive with my Time Machine backups on them, then I opened Finder and click on my external hard drive under devices.
    2.) Next I clicked on and opened the folder named "Backups.backupdb"
    3.) Once inside that folder I could see folders with the backups from Time Machine and all of the folders names were the date I backed up that backup. I clicked and opended the lastest backup folder.
    4.) Inside that folder, I clicked and opened the folder named "Macintosh HD"
    5.) Inside that folder, I clicked and opended the folder named "Users"
    6.) Inside that folder, I clicked and opended the folder named "Daniel" which was my Username on my previous Mac.
    7.) Finally I could see and access all my folders from my Time Machine backups from my previous Mac.
    Keep in mind this is only helpful if you are trying to access old backups (backed up from another Mac) on a new or different Mac. (Sorry for the blurry images)
    Hope this somehow helps someone else,

  • Can i use an external drive in macbook pro mid 2012?

    replaced my optical drive with new matshita UJ8A8 drive in my macbook pro 13 mid 2012. problem was prior to replacing every type of disc wold be ejected, now when disc goes in new drive makes a sound and then ejects???? any ideas? I have 16 gig of ram in pc

    I'm not sure why it wouldn't? The Apple external USB SuperDrive will not work with your machine, but there are a lot of other third-party drives out there that should have no problem. Even though you have USB 3.0 ports on your machine, any USB 2.0 external optical drive should be fine -> a slow optical drive (and they're all slow at writing and reading asa  limitation of the media, not the port) is the norm.
    If I were you, I would just check out one of the $30-50 Asus, LG, etc., external optical drives out there. It should work with any Mac.
    Good luck,

  • HP Pavilion external monitor has stopped working with my Macbook Pro (Mid 2012) with OSX 10.8.3

    HP Pavilion external monitor has stopped working with my Macbook Pro (Mid 2012) with OSX 10.8.3.  When I purchased the monitor a few weeks ago it worked perfectly when computer was in clamshell mode or with lid open. Now external display has stopped working.  When I turn on display it scans for signal but does not find it and then immediately goes into sleep mode.  I am using a DVI connection with the adapter for the mini display plug.  REALLY FRUSTRATING. Any help would be extremely appreciated.

  • My Macbook Pro (Mid-2012) won't connect to an external display using my MiniDP to VGA Cable.

    I'm on a Macbook Pro (Mid-2012) on Mac OS X 10.8.3 (currently downloading the update to 8.4). When I plug in my Mini Displayport to VGA adapter to my Mac, the screen flickers blue for a second and the Display Settings window detects the other monitor and allows me to rearrange the screen, but it does not project anything onto the other monitor. However, I tried connecting an Apple Thunderbolt Monitor to this computer today, and it worked. This wasn't a problem before, as I was able to connect this Mac to other LCD projects before. Furthermore, I don't think it's an issue with the adapter either because it's relatively new. I also tried plugging in the adapter of another Mac (which was working fine) into my Mac, but it didn't work either.
    Here's what I've tried:
    1. Restarting the computer with everything plugged in
    2. Pressing Command + F1 when it's plugged
    Any advice would be helpful!

  • Can I use my macbook pro mid 2012 as an external display using thunderbolt port

    Hi,
    I want to use my macbook pro (mid 2012) screen as an external display for a raspberry pi using a HDMI to Thunderbolt cable, via the thunderbolt port on the macbook pro. Would this be possible? Can the macbook pro's thunder bolt port act as an input and is any additional software required?
    I look forward to hearing from you.
    Thanks in advance!

    Welcome to Apple Support Communities
    You are referring to Target Display mode. Target Display mode can only be used in 27-inch iMacs and iMacs with Thunderbolt, not MacBooks Pro > http://support.apple.com/kb/PH11302
    Unfortunately, you can't use the MacBook Pro as a display. It doesn't support the monitor mode

  • I want to remove the monitor from my 17" Macbook Pro 2008 to use as an external for my Macbook Pro 15" 2012. How can I convert lvds to Thunderbolt and power the monitor?

    I want to remove the monitor from my 17" Macbook Pro 2008 to use as an external for my Macbook Pro 15" 2012. How can I convert lvds to Thunderbolt and power the monitor?

    It's almost impossible.  The new iMacs have a Target Display Mode, but it's built to do that.  Without ripping your screen out, finding an acceptable power supply, frame, and whatever electronics to convert a Thunderbolt signal to the screen, the cost will be much larger than buying a cheaper HiDef monitor that runs with an HDMI to Thunderbolt cable to your MacBook 15.  In fact, you can sell your 17" MBP for a lot of money, unless it's broken or something, buying you a really sweet monitor.
    By the way, I found your answer by searching this forum.  I would suggest using the search function here in the futuere.

  • Problem with bluetooth connection between iPhone 5s iOS 8.1.2 and MacBook Pro (Mid 2012) Yosemite 10.10.1

    After the upgrade to iOS 8.1.2 in iPhone 5s and OS X 10.1.1 Yosemite (MacBook Pro Mid 2012) can not connect my iPhone 5s to the MacBook, the iPhone tells me: "The MacBook is incompatible" or the message "Connection Error, Make sure the Mac is turned on and is within range" even the iPhone being close to the Mac. Otherwise with the updated iPad 2 (iOS 8.1.2) is connected via bluetooth to the MacBook without any problems, Even the iPad 2 does not detect the iPhone bluetooth.

    An iPhone will not pair via Bluetooth to a computer (Mac or Windows) except for personal hotspot and then only if your cellular plan supports it. https://discussions.apple.com/docs/DOC-7722
    If you are attempting to use Handoff/Continuity, that does involve Bluetooth but the devices are NOT paired; Bluetooth just needs to be on and the devices in range of each other. The following may help with Handoff/Continuity issues: http://support.apple.com/kb/TS5458

  • Macbook pro mid-2012 13" has very slow disk access

    Until 3 days ago my macbook pro mid-2012 13" running OX 10.8.3 was running fine. Then, it showed very slow response anytime it had to access the hard disk. After doing the usual checks and disk first aid repairs to no avail, I booted from my external disk with an older copy of my hard disk and everything then worked as normal, except when I accessed the internal hard disk, then it crawled once again (spinning beach ball, took many seconds just to open a finder window and then several minutes to display the contents). I ran the Apple Hardware Tests and it said everything was fine, even though it tooks several minutes before the test would actually start. I also ran the program BlackMagic Speed Disk to find out if the disk was having transfer speed problems and it showed a respectible transfer rate (60MB/s), not great but not like the 0.3MB/s I was getting when I tried to back up the internal disk. I was using Carbon Copy Cloner to try to back up the internal disk but had to give up since at 0.3MB/s, it would take days to back up the 250GB on the disk. I found on the web that using "restore" in Disk Utility, I could do a disk copy without the file by file copy which allowed me to back up my disk in "only" 6 hours. Booting from my newly made copy on an external disk worked fine and ran at nearly normal speed (slightly slower since it was an external disk running through USB2). As a final attempt to prove this was a disk problem, I erased the internal disk and reinstalled OSX 10.8. I am still waiting for this install to finish, it has been 5 hours although the progress bar said it should be done in 20 minutes. This was fairly convincing evidence that it is not a software or settings problem. However, all my web searches could find no other case of a problem like mine. I presume I have a failed hard disk but as all the diagnostic programs say it is working fine, I was hesitating to bring it in without hard diagnostic evidence. If anyone knows what might be the problem, it would be much appreciated to hear from you.       

    It should not take 5 hours to install Mac OS X.  There is something wrong with the disk.  Try reformatting where you do a wipe of the drive (an select the option to write zeros which will remap bad sectors).   Then try to install MAc OS X.
    I got this information from here:
    http://reviews.cnet.com/8301-13727_7-20064489-263.html
    Back up your data.
    Use Time Machine or a system cloning utility to create a full and restorable backup of your data. If you suspect bad blocks, then when cloning you might consider not using a "block-level" copy process, since this will likely run into problems.
    Boot to the utilities DVD.
    If you have a boot DVD for a tool like Drive Genius or another drive utility, then boot to that; if not, use your OS X installation DVD (once you select your language, open Disk Utility from the Utilities menu).
    Format the drive.
    Using your selected utility, format the drive and check for bad blocks. If you are using Disk Utility, click the Erase tab, click the Options button, and then select the option to write zeros to the disk (you do not need to do multipass erase options, as this will provide no additional benefit for managing bad blocks). Writing to zeros may take a couple of hours depending on the size of the drive, but when done the drive will have remapped any blocks that were not reliably read.
    Restore the OS installation.
    If you have used Time Machine to create your backup, boot to your OS X installation DVD (if you are not using Disk Utility) and use the option in the Utilities menu to restore from backup. Attach your Time Machine drive and then proceed with the restoration, selecting the newest backup as the one to restore to your system. If you have used a system cloning tool, then attach the cloned drive and boot off of it (hold the Option key at start-up to select it from the boot menu). When you are booted to the cloned drive, run your cloning utility to copy the installation back to the computer's main boot drive.An optional approach here is to perform a full reinstallation of the OS from your installation DVD, and then migrate your data, applications, and settings from either the clone or the Time Machine backups using Apple's Migration Assistant.

  • Macbook Pro Mid 2012 15" Retina - Display blackout on restart.

    I am having a major issue with my 15" Retina MacBook Pro (mid 2012). When I shutdown the Macbook, and boot it again later, it is not showing anything on screen.. Even the grey screen on bootup.. Completely black.. I can hear the startup chime, and a bit later, keyboard backlight turns on, which is indicating that the boot process is completed.. But no display.. Even for 15-20 min.. I cant even access Bootcamp and Apple Hardware test.. (Even if they are available, I can't see them on screen.. Fully black.. And I can't know where to click on what, in that darkness..)
    But one small thing I found was, when the keyboard lights up, I just closed the lid.. It then goes to sleep.. Again opened it.. I found the screen working normal, after a small flashing of Blue screen.. I'm thinking that this problem occurs only at startup, but not at sleep.. This is not a solution, but a temporary remedy..
    Can anybody help me over this issue..??

  • Macbook Pro mid 2012 15" (non-retina) graphics tearing

    Hello everyone,
    I would like to post my experiences using two identical macbook pros 2012 (non-retina, with nVidia GT650M 512MB) who presented the same graphics cards glitches and problems, and hopefully to obtain some information.
    Exhibit 1: My own macbook pro
    Bought from France, in November 2012. Used mainly for professional non-graphics programming, it's clean, no bloated software, and only necessary professional tools are installed. 16Gbytes of memory, by Crucial.
    At some point during July, when the machine was relatively cold and I was watching a youtube video, this happened (see attached pics). The mouse was moving, and the computer was fully operational, but with this "glitchy graphics overlay". I logged out, and logged back in. Problem disappeared and appeared again at random times, 4 times during an hour. All those times, a log-out and log-in would fix the problem. After that, I could not reproduce it. Apple changed the motherboard, claiming that it could be a faulty nVidia card.
    Exhibit 2: My brother's macbook pro
    Bought from Greece, in february 2013. Same model as my own, same RAM, same specs. Used for professional video editing, no bloated software, mostly using Final Cut Pro X. He noticed various malfunctions with FCPX, like freezing when applying a visual effect, and graphics tearing when rendering (that's when the nVidia card kicks in, normally). Yesterday, same symptoms as my macbook pro appeared, graphics tearing, etc.
    EDIT: videos of the problem:
    http://www.youtube.com/watch?v=jGBijGMO9NE
    http://www.youtube.com/watch?v=jnEXtVWgKKM
    Both machines are in a completely different environment (I live in France, my brother in Greece), non-smoking areas, and have worked in completely different ways. Both with OS X 10.8.4.
    That's two out of two. Given nVidia's background, I am starting to feel that my purchase is not so reliable as I originally thought, and I am thinking that this problem is more generic than originally seemed.
    Does anyone have any relevant information on this matter? Could these problems be related to issues with nVidia drivers? Is there any information about unreliable nVidia graphics cards on 15 inch macbook pros mid-2012 (non-retina)?

    Hi there,
    I would recommend taking a look at the troubleshooting steps found in the article below.

  • Macbook pro mid 2012 backing up from disk ulitiy asking for "login" keychain?

    I bought a "WD My passport For Mac 1TB" portable external hard drive since I can't get into my macbook pro mid 2012 10.9 because when I turn it on its just grey screen with apple logo and spinning wheel. I went to future shop to the geek squad and they did diagnose of it that is wasn't the hard drive but the operating system with problem. Which makes sense since I did the apple hardware test, disk repair/verfy, permissions repair/verify and they all came back with saying my volume is ok etc.
    SO my question is to back up my files etc. I do the command + r and go to disk ulitiy and click on "Macintosh HD" and then click "New Image" and then select "My Passport for Mac" to save on there. What I want to know should I put "compressed", "read/write", "read only" or "DVD/CD master" for Image Format? AND For encrytion, do i pick "128-bit AES encryption (recommended)" or "256-bit AES encryption (more secure, but slower)"?
    Also I have one more option before I go to my genius appointment on saturday is to do the "erase and reinstall" option. Of course I need to back up my files to do that which is why I am asking the questions above. Can any one link me to the "erase and reinstall" option OR tell me your experience on how to do it OR how to do in overall? Also, is it an effective method? I already have the important files on my google drive, have my microsoft disk stuff on my USB, the only app I kind of don't want to lose is my "Notes" app. Also for the apps I downloaded in Apple store they should be still there even if I erase my hard drive?
    So I did  the command + r and go to disk ulitiy and click on "Macintosh HD" and then click "New Image" and then select "My Passport for Mac" to save on there. I put "read/write" for Image Format AND For encrytion,  i pick "128-bit AES encryption (recommended)"
    I put in a password when prompted but after that it says "Disk Ultitiy wants to use the "login" keychain." I put in my ususally login password that I use to get on to my desktop but that doesn't work. I have the option to press ok or cancel. Can I just press cancel and will it contiune on backing my files to my external hard drive?
    I pressed cancel and the progress bar to saving my macintosh HD to MY external hard drive portable isn't shown any blue bar progress for 9 mins now...
    do u know what to do?

    If you like you can also restore, via Disk Utility, the DMG onto another disk, but you will be able to read the contents, simply mounting the volume inside any version of OS X.
    ^ What do you mean by this?
    Also, It says on here:Mac OS X v10.5, v10.6: How to back up and restore your files - Apple Support
    When the imaging process is complete, select the newly created disk image in the device pane.  Then, choose Images > Scan Image for Restore... from the menu bar, and let the scan complete.
    Quit Disk Utility (press Command-Q). Then press Command-Q to quit the Mac OS X installer; you will be prompted to restart.
    Restoring the backup disk image's contents to your internal Mac OS X disk
    What does Images > Scan Image for Restore mean?
    Also  If I erase hard drive and then reinstall mavericks OS X from "command + r mode" and after that hopefully I can get back in would I hook my external hard drive and then open the copy of the "macintosh".dmg and drag everything back on? or...?
