Lightroom 5 color labels appear dark causing mac pro monitor(s) to go black, have to restart, get a kernel panic os 10.7 5

I have a Mac Pro 12 core, with a Nvidia Quadro Pro 4000 video card. I have been using lightroom with this video card since 2011 without a problem. I updated to os 10.7.5, which apple says it is the latest f  and now when i use lightroom (after about 15 minutes),  my monitor goes black, which i am sure is a video card issue which involves lightroom settings, and i have to restart my system. After restart I get a kernel panic report. I unistalled lightroom, and had no crashes. I reinstalled it and i started to get computer crashes again. (not lightroom crashes but computer  -) When i open lightroom, the color labels appear saturated and much darker than usual. I took a screenshot www.jlanceimaging.com/lrscreenshot.jpg.
Since updating to 10.7.5 i have had this issue with lightroom and the video card.
I also went into photoshop an unchecked the graphics processor but still got the crashes.
and last;y, i opened up lightroom 4 and had no problems

You don't say what, if anything, you have done to test, resolve or rule out causes, so you can always assume hard restarts, freezes, and not safe shutdowns will make for more problems (corrupt files, file system, directory, etc).
Running Apple Hardware Test; Reset SMC; repairing your drives; ruling out cables, controllers, external devices, even drivers for printers and other devices.
If you are on a UPS, it should be 1000VA or larger (1300-1500VA). If there are other devices and you could be exceeding the load on circuit breaker, also worth looking into and sometimes requires adding a new circuit line.
A good place to start is

  • Mac Pro - crashed and now won't start up, stripes on screen + kernel panic?

    My computer apparently crashed while the screensaver was up (I was away for 10 or so mins, just Firefox and World of Warcraft in windowed mode running), as it was showing a black screen with a fuzzy whitish line along the top and was completely unresponsive. Unusual, but nothing to freak out about.. right?
    So I did the on switch turn off/turn on routine and as soon as anything shows on the screen, I've got these black + white horizontal bars/stripes along the top 1/4 of my screen. The Apple Logo and the spinning progress bar have little fuzzy red spots on 'em. That's when it's time to freak out, as we're in "my computer done broke itself" territory. A few seconds of fuzzy progress bar and we get the wonderful "You need to restart your computer" message.
    Fine.. restart.. same thing.
    Reset the PRAM and SMC. Same thing.
    Can't start up from external disks.. it just gives the same stripes + message.
    I'm running a detailed hardware test (the hardware test loads but with the same stripes at the top and annoying blue/red vertical ones in the background to boot), and it's been running for about 80 minutes and is only 60% of the way through.
    Anything else I can do, or do I have to drag the heavy thing to an Apple store and leave it there for a month? How in the world does a computer go from "working fine" to "completely broken" in 10 minutes?

    More details:
    The regular/non-extended Hardware Test returned no problems, despite taking hours for what was supposed to be a 3-5 minute test. I haven't dared run the extended.
    I also tried removing third-party RAM and using the original configuration, then just the third-party and no Apple, etc.. It's not the RAM, as the problem is exactly the same.
    I'm going to call up Apple support when I can, but just looking for other things I can check or possibly do until then, or just insight on what the problem could be.
    Is it most likely the graphics card? Could it be an issue with the core hardware?

  • I have a 30 inch monitor on my mac pro tower that just went black, what do I do to fix it?

    I have a 30 inch monitor on my mac pro tower that just went black, how can I get it back on?

    He's asking what are those things you are using, i.e., ...
    What video card are you using?
    What version of OSX are you using?
    What model of mac pro are you using (e.g., 2010 Mac Pro is 5,1).
    And also,
    Try smc and pram reset.
    And see if the monitor lites up if you boot in safe mode.
    It is possible your monitor simply failed -- its power supply or something else.

    I have been using a Lightroom 5 including recent upgrades on my Mac Pro laptop for the past 1 year. This was purchased as an upgrade from Lightroom 4 for which I have a serial number. Today I purchased a new Macbook pro and loaded my Lightroom 5 however it is asking for my serial number which I have misplaced. I am unable to trace my serial number anywhere. I have even checked my adobe membership to locate my serial number but it does not seem to have any record which is strange as I have been using this software for over a year now and the previous versions since 2009. Could someone help me in my predicament.

    I use my own color profiles from Photoshop CS6/Mac Pro - how do I turn of Epson Artisan 837 printer color management?

    Choose Photoshop Manages Color in the CS6 print dialogue. At the top, click the Print Settings button and disable any color management settings for the printer.
    Edit: Correction, that's CS6 in Snow Leopard. In Mountain Lion, if you check the print settings, color management for the printer should automatically be disabled when using Photoshop Manages Color.

  • Mac pro 1.1 2006 universal black  power lead uk

    Hi as i am new to Mac could using the wrong power cable cause the mac pro to go into power safe mode ?
    i get a message on my screen saying DIGITAL INPUT IN POWER SAVE MODE,PRESS COMPUTER POWER BUTTON AND ANY KEY ON KEYBOARD OR MOVE MOUSE
    TRIED IT BUT NOTHING HAPPINS

    So many times we get to the hardware details needed after some Q & A back and forth....
    Any PC graphic card will work if you get Windows to install, which is harder on a 1,1 Mac Pro 2006.
    The 8800GT may not be powerful but powerful and Mac Pro would require a 2009 or later, improved PCIe 2.1+
    Up until a month ago the safe route was Apple's own 5770 - AMD card that worked in all Mac Pro models if they have 10.6.5 or later.
    your last post sounds like you quoted but no acknowledgement where, sounds like ebay's MacVidCards is a good reliable source of cards, mostly Nvidia. Use to have 1GB 8800GTX too.
    There are forums that get into flashing and 3rd party PC card support.

    How to Perform an Archive and Install
    An Archive and Install will NOT erase your hard drive, but you must have sufficient free space for a second OS X installation which could be from 3-9 GBs depending upon the version of OS X and selected installation options. The free space requirement is over and above normal free space requirements which should be at least 6-10 GBs. Read all the linked references carefully before proceeding.
    1. Be sure to use Disk Utility first to repair the disk before performing the Archive and Install.
    Repairing the Hard Drive and Permissions
    Boot from your OS X 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 Installer menu (Utilities menu for Tiger, Leopard or Snow Leopard.) 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 installer. Now restart normally.
    If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
    2. Do not proceed with an Archive and Install if DU reports errors it cannot fix. In that case use Disk Warrior and/or TechTool Pro to repair the hard drive. If neither can repair the drive, then you will have to erase the drive and reinstall from scratch.
    3. Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When you reach the screen to select a destination drive click once on the destination drive then click on the Option button. Select the Archive and Install option. You have an option to preserve users and network preferences. Only select this option if you are sure you have no corrupted files in your user accounts. Otherwise leave this option unchecked. Click on the OK button and continue with the OS X Installation.
    4. Upon completion of the Archive and Install you will have a Previous System Folder in the root directory. You should retain the PSF until you are sure you do not need to manually transfer any items from the PSF to your newly installed system.
    5. After moving any items you want to keep from the PSF you should delete it. You can back it up if you prefer, but you must delete it from the hard drive.
    6. You can now download a Combo Updater directly from Apple's download site to update your new system to the desired version as well as install any security or other updates. You can also do this using Software Update.

  • I would like to display what's on my Mac Pro monitor on my iPad with as little latency as possible. What's the best way to do this?

    I would like to display what's on my Mac Pro monitor on my iPad with as little latency as possible. What's the best way to do this?

    Your image history (if I understand you properly) is stored in your catalog file, and nowhere else, and so it is only on a single drive.
    Do you mean you have edited photos on multiple drives? This isn't a problem for Lightroom at all, the software doesn't care, and you can leave things just the way they are. But if it bothers you for some reason, you can move the photos to a single drive if you want. In Lightroom select the desired photos or folders (it's easier to do this using Folders) and drag them to the desired drive.
    Alternative if you will be moving lots of folders: Adobe Lightroom - Find moved or missing files and folders

  • I have a Mac Pro OS 10.7.5 and have a DVD+R disc with files on it, but it ejects the disk after about 10 seconds--what to do?  How can I get the data off this disc?  I can see it has been already burned, so files are on there?

    I have a Mac Pro OS 10.7.5 and have a DVD+R disc with files on it, but it ejects the disk after about 10 seconds--what to do?  How can I get the data off this disc?  I can see it has been already burned, so files are on there?

    Try cleaning the lens and see if that will restore functionality to the DVD drive.  Use a DVD lens cleaning disk, if you have a can of compressed air, shoot some into the slot or wrap a fine microfiber cloth (eyeglasses cleaning cloth)  around a business card and insert it gently inside the slot.
    If no success, make an appointment at an Apple store genius bar and get a free diagnosis from them.

    Hello i would like instal windows in my mac pro retina but i don't have boot camp

    What version of OS X are you running on your MBPr?
    If you open Applications > Utilities, you should see Boot Camp Assistant in that folder.
    That is the utility which will create the partition into which you can install Windows that you have purchased from Microsoft.

  • Moving photoshop elements 12 and lightroom 5 from windows machine to a Mac Pro

    Is it possible to transfer licence from the windows machine to the mac?
    The Lightroom version does appear to be a windows/mac version but the serial number won't activate the product.
    The Photoshop Elements was actually a windows version so perhaps that is more excusable.
    But is one really expected to either buy this software again or just forget about them all together?

    For Lightroom and Elements your license covers both Mac and Windows.  You do need to install the appropriate version in each case however.  I Windows version will not work on a Mac, and vice versa.
    If you continue to have a problem you should contact Adobe support thru chat... Start Here  If after selecting relevant responses you are unable to find a solution, choose "Still need help? Contact us." and the chat contact option.

  • Going into my hard drive causes mac pro to lock up like fort knox

    Hi, I have been a mac user for just a hair over a year.(Apple will not help me with anything)
    All has been swell until now.
    If I go into my hard drive my computer locks right up. I can do
    nothing to move it along. The only option I have is to hold down the
    power button for six seconds, which kills me and the computer a little
    each time. I booted up the computer using the mac install disc and I
    used disk utility to "repair" the disk. It reported the disk was "OK".
    I thought swell, and went into documents on the hard disk and it
    locked my computer up again. I let it sit there for an hour and
    nothing moved. apple/option/esc does not do anything. I went into time machine and
    went to the documents there and it locked up the computer too. I went into finder and went to documents and it locked up the computer. I went into other areas of the hard drive and it locked up the computer. The funny thing is I can go on the internet, use programs, read email, and everything works fine. Can anyone guide me in
    the right direction in solving this problem I am facing?

    Sounds like itneeds some good basic maintenance and troubleshooting. Stop using this drive. Start trashing temp files, and off loading good files.
    Everytime you freeze and do a hard restart, the chance that the journal, directory, file system and data are compromised increases, in spite of the "OKAY" from Disk Utility's repair routines it is not reliable. And leads to false sense of security. Disk Utility only checks the basic directory, not the files themselves.
    It may be something like a damaged Finder plist/preference, or worse, but either you look for an easy fix, or just start cleaning up and moving files and system to a good drive and system.
    You may have bad blocks on your drive causing all this. Or not. TechTool can detect bad sectors, but not map them out. (Deluxe is part of AppleCare; or Pro, commercial version).
    Start using SuperDuper if you don't already, and Disk Warrior, premiere for disk repairs.
    http://www.shirt-pocket.com/SuperDuper/SuperDuperDescription.html
    What you need to be doing is rebuild your system from the foundation up.
    You may need to check out Data Rescue II demo from Prosoft Engineering to recover files.
    I would begin by installing OS X on another drive, or restoring from TimeMachine. Create/name an "emergency" boot drive partition. Doesn't need to be that large. Keep it handy just for doing repairs and maintenance. Keep another as a clone of your working system and backup - in addition to TimeMachine.
    You may want to start by erasing the drive (not just the OS volume) with a 7-way write (not just zero all, it does NOT do a reliable safe job mapping out bad blocks) and restore from TimeMachine. Or work with a new drive.

    So I have to reboot manual with holding power button, but cannot load osx (blank screen), I try to hold smc reset button, don't work too.
    So I unplug and plug the memory raiser, so finally everything back to normal. It can loading osx snow leopard normally.
    So what is the problem?
    Thank you,
    David

    It's a hardware fault. I suggest you make a "Genius" appointment at an Apple Store to have it tested. It's a free service. The repair won't be free, but if it's something simple, such as a bad memory module, you may be able to fix it yourself.

  • Mac pro monitor has a shadow in its center. Does anybody know what can cause that?

    Last day my mac pro showed a shadow in its display center. Does anybody know what can cause?
    I use to use it a litle, cause i'm new on macs and still use pc based on windows.

      Who made the monitor?  Is it even Apple?
      If you have the right connections, try swapping out the monitor with your PeeCee monitor and see if the problems stays or goes.   But does sound like a monitor issue.  But then, hard to know what you mean by shadow...
