Mac pro cinema display cuts out and can't access Mac with screen sharing

Hi
A weird thing has started happening to my Mac Pro today. After using it for a few minutes the cinema display it is attached to on the Mac Pro just goes black. The Mac Pro is clearly still on - the light is on and i can hear the fans. The Mac Pro shows up on my local network and i can connect to it and access files from my Macbook, but screen sharing doesn't work (i just get the message 'contacting mac pro' and nothing else) and i can't connect to shared iTunes library either, which makes me think it is not just a display issue. I cannot wake the computer with the mouse or keyboard, which makes me think it isn't just a sleep issue. All i can do is physically turn the Mac Pro off, start it up and it will start up successfully and then work for a few more minutes before i get the same problem. I have reset the PRAM and SMC and still have the same problems. Can anyone suggest anything else i can try?
I should mention that i have another problem with the Mac Pro in that it has been spontaneously waking up from sleep and starting up from shutdown, and i still haven't resolved this. I don't know if it is connected to the above issue.
thanks

I have experienced almost the exact same thing with my new 2008 Mac Pro and my 30" Apple display. It has happened to me twice in the last few weeks. The first time I chalked it up to a fluke, but now that it's happened again I searched the forums. In both cases I've had music playing in iTunes which continues playing, goes on to the next track, and so on. So the machine has not crashed in full. I too can connect to the files via another computer on the network, but cannot share the screen.
I have not had the sleep issues you have had.
I'll look at the link you provided in your next post to see where that gets me, but I wanted to let you know you were not alone on this one.

  • My ipad keeps cutting out and going back to start up screen, my ipad keeps cutting out and going back to start up screen

    my ipad2 keeps cutting out and going back to start up screen?

    First, try a system reset.  It cures many ills and it's quick, easy and harmless...
    Hold down the on/off switch and the Home button simultaneously until the screen blacks out or you see the Apple logo.  Ignore the "Slide to power off" text if it appears.  You will not lose any apps, data, music, movies, settings, etc.
    If the Reset doesn't work, try a Restore.  Note that it's nowhere near as quick as a Reset.  Connect via cable to the computer that you use for sync.  From iTunes, select the iPad/iPod and then select the Summary tab.  Follow directions for Restore and be sure to say "yes" to the backup.  You will be warned that all data (apps, music, movies, etc.) will be erased but, as the Restore finishes, you will be asked if you wish the contents of the backup to be copied to the iPad/iPod.  Again, say "yes."
    Finally, if the Restore doesn't work, let the battery drain completely.  Then recharge for at least an hour and Restore again.

  • Mac Pro / Cinema Display slow boot time

    Hi there,
    I have a late 2008 Mac Pro, running OSX 10.6.8 and it is connected to a 23" Apple Cinema Display.
    A couple of days ago I noticed that when I switched the Mac on, the display would not turn on.
    I forced it to shut down by holding the power button, and tried again, but nothing.
    Today I switched it on, and again the display did not turn on, but I left it like that, and after about 25 minutes it turned on.
    I shut it down from finder, and switched it back on and it worked instantly.
    I used Disk Utility to clean up my disk, but I can't run a Disk Utility or Hardware Test from the CD, as the optical drive has not been working well for a few years.
    I am guessing that it may be the display needing a while to "warm up" so it is dying, or that it might be a RAM issue that after the first long boot resolves itself.
    Any thoughts as to how I should look into this more?
    Thanks!!

    Never use DVDs myself, definitely not for repairs.
    Install OS X or clone the drive and have a 2nd bootable backup.
    CCC can check files with checkum for integrity during copy (have to go into advanced options for copy operation).
    Always have even a small boot drive handy. Even a flash drive can serve your purposes.
    DU checks the directory. You don't clean up, not with DU and not with 3rd party "cleaner" apps.
    You can do a Safe Boot, or try, and even run fsck -fy in Single User Mode in a pinch - the Safe Boot though you should try.
    I would suspect the GPU. Beyond that, just 2008-itis that affects these 3,1 models more than any other. And yes SMC and NVRAM reset and remove all devices. Even slide out the disk drives and anything else. And press the power on button for 10 seconds while unplugged, to fully reset. NRAM is done from cold boot and the old 4-finger salute of P+R+CMD+OPT keys.

    I am not sure what monitor will run on this mac pro bought in Spring of 2007.  Is there any monitor with a built in camera that can be used on this machine?
    I have confirmed with apple that it cannot run the LED monitors that apple sells. 
    suggestions or if you know what monitors I can try to find would be great.  If you need more information, please let me know.  I want to be able to do this right.  Thank you so much.

    I know there were many more problems 5 yrs ago with 3rd party monitors and have been some issues in between also.
    Apple does have what is needed to use multiple 30 inch displays and the 5770 is pretty mainstream and standard.
    It is also about the only card being sold outside ebay and a couple places in case you want to take your chances with Nvidia 8800GT 1st gen model or ATI 4870.

  • Extensions grayed out and can't access plug-ins

    I've used the water mark plug-in before and it worked just fine but now when I go to window>extensions, the "extensions" are grayed out.
    Macbook pro 17" with OS X 10.6.4.
    Photoshop 12.01, mode RGB, 8-bit/channel.
    Watermark 2.0.6. (2.0.5 didn't show up so I loaded the newer version before I noticed extension were grayed out)
    The plug-ins are listed under "about plug-ins"
    I use Font Agent Pro4.140 and installed the plug-in for Photoshop.
    Extensions manager shows Watermar installed.
    There is no Extensions Manager under "Help" in Photoshop.
    I have no idea what to do to get to my plug-ins.

    It took me all day to fix this problem but right now the extensions are visible again.
    Deleting Photoshop preferences didn't fix it.
    Uninstalling Photoshop and then re-installing didn't work.
    So I uninstalled the complete CS5 suite and hope that I got rid of everything before reinstalling the whole suite. I applied updates, installed plug-ins and it now works. What a pain. I am not very happy. I've never had to do this before and I would really like to know what turned the extension off so I don't have to go through this again. Now I am ready to personalize my short cut keys, etc.

  • My MacBook Pro randomly disconnects from Safari and can only access it after I restart my computer...What is wrong? and how do I fix it?

    I restored my MBP to factory thinking that would help...NOPE! I spend a great portion of my day on the web, networking for my writing, what can I do...getting desparate.

    While I'm using Safari, whatever site I'm on...freezes, it just locks and won't refresh or do anything. I'm unable to redirect to anyother links or sites. At this moment I have to close Safari and restart my computer to get my internet to work proper again for a short while. I am on a wireless network. Everything worked great with NO problems for the past year then about 3 weeks ago I started having these issues. I've never used anything but Safari. My GMAIL also went funky at the same time and wouldn't display properly. Since I restored my MBP, my GMAIL is working again, but the internet still freezes. When it freezes, my airport still shows full connection.

  • My display freaks out and gets 4 of the same screen one it

    I have my display (apple cin of course), hooked to my Macbook Pro.  It has worked perfect for about a year and now it is clicking on and off every once in a while.  Then yesterday is went off and came back on with 4 of the same screen on the main screen and it was all jumbled up.  Why is it doing this and is the display failing?

    It sounds like the display or video card could be failing.  Try an smc reset but it probably won't have any affect.

  • Photoshop CS6 on a Mac Pro 1,1 - how much RAM can it access?

    Hi everybody,
    After reading many related threads, I have gathered that the MP 1,1 has 64bit architecture, but only runs a 32bit kernel. Will this limit PS CS6 accessing all the RAM (currently 13 GB) on my MP 1,1?
    Many thanks!

    There are still benefits to more RAM when working with files that can grow or take up more memory even though you are not using 64-bit kernel, but still able to run CS6 as a 64-bit application.
    people have outfitted their MacPro1,1 with more than 16GB to full 32GB to improve performance. That along with SSD for scratch and another for system (or use an array for scratch, though memory is your best "scratch") and of course an array for loading files and for your save volume (2GB files taking too many seconds?).

  • HT1338 cinema Display 30" no longer recognized by my mac pro? What can I do? It worked fine until now.

    Cinema display 30" no longer recognized by my mac pro. Until now it worked without problems, then after a crash it fails to recognize the display.
    Now it runs in a far lower resolution. What can I do?
    I tried to get da driver for it, but could not find any.

    Try the other DVI port on the graphics card.  On early Mac Pros, only one port is the dual-link DVI needed for full resolution on the 30" display.  Make sure the display's USB cable is plugged into the computer.

    Hello (hopefully someone can shed some light on my issue)
    I own as above a MAC PRO (Early 2008) this has a RAID card installed along with two 15k.7 cheetah hdd (320gb) and a spare drive, (which i made a regular drive)
    a while ago i had to replace the RAID card battery, so i did this, over a year later the same thing happened again, but as previous just left it and the system seemed fine for ages, until last night i was working in PHOTOSHOP and everything just froze and the screen kind of appeared GREEN, could not do a single thing. So restarted the mac, this time grey screen for ages and a message appeared, (macs version of blue screen) (see attached).
    I restarted the machine and this time a flashing question mark folder!
    could not do a thing.
    so i found my copy of snow leopard and got the computer to run this and at least launch the DISK UTILITY and (Interestingly in the drop down menu RAID UTILITY was also in the menu) but it did not matter which utility i used the (RAID or DISK) neither could see any of drives, just the dvd drive.
    so looked around on you tube and various forums and discovered if i take out the RAID CARD and re-plug the main lead from the RAID card back in to the LOGIC BOARD I would be reverting the MAC to a normal regular non-RAID computer.
    After performing this HARDWARE task and inserting all three HDD, and running the DISK utility from the drop down menu via the SNOW LEOPARD disc.
    (interestingly since the RAID card had been removed the RAID UTILITY  from the drop down menu no longer appeared). running disk utility I can now only see the regular (spare) hdd and DVD Drive, but the two RAID HDD , again, still do not show up DISK UTILITY?
    O.K. so i could chuck out the RAID card (AND RAID HDD) and just go with a regular set-up, and run a back restore from Time Machine on a NEW hdd purchased.
    but what is wrong with the RAID, is the card at fault or are both HDD used for the RAID knackered? can i perform any tests, to see whats what?
    thanks for your help in advanced.

    hello people, the issue was in fact the GRAPHICS card nothing to do with the HDD or RAID system ( although this did cause issues with the RAID system it basically lost its way) below is my replay to another similar  problem some one else had!
    working in photoshop and then everything stopped working and the lot froze! only option was to force shutdown (via button).
    and try to restart, hoping all was fine, this was not the case :-(
    I had the added issue of the RAID card system, that i have, this was confused to say the lease and would not behave or work, causing the start up to hang.
    so i thought the HDD must be bust and the root cause. ( but soon learnt it was not the cause )
    ...bought a new HDD removed the RAID card and replugged the cable from RAID card into LOGIC board, ( making the computer act like any normal non-RAID system). I managed to install the OSX, using the snow leopard disk way. once the mac was running, i started to notice the screen would flicker and started to see 'artefacts'. so i started to reveal my symptoms to the web and forums and soon discovered that my graphics card could be the issue all along?.
    (nvidia geforce 8800gt 2x dvi).
    I read up on that a fix, could be either A. reply the thermal paste, as the card could be over heating or B. stick the card in the oven trick.
    Tried option A. first and nothing still issues, so last night took the plunge carried out option B. and ta da it worked! i even managed to run
    from my new HDD my lasted install OS X, absolutely fine. I then thought, maybe i could repair my RAID so replugged all the HARDWARD back in and
    carried out a disk repair and disk permissions on drives( took a small amount of time), via the SNOW LEOPARD disc - (Disk utilities) and this worked and now have my system working as it was just over 6 days ago.
    what was the cost to get this?  bought a new hdd so 40.00gbp and thermal paste and cleaner kit ( your still need to do this ) search video card trick on you tube.
    and renew thermal paste, approx 15.00gbp, technically i don't need the new HDD, but it was all part of the trial and error way i went. ( i do have extra storage as a result!)"
