No More drivers when i restart my MAC PRO XEON

Good day !
So here is my problem :
I have two Pioneer Drivers 116 and 112. I initialized my hard disk and after install and restart, my drivers don't appear at all. When i do "about this mac" / more information and ATA,
No drivers on my MAC PRO XEON, all vanished !!!
And when i open the MAC, the power supply of my two drivers are working, i hear the sound of "the power supply" i don't know if it's correct... cause my english is approximate.
Did you heard somewhere the same problem ?
I don't understand.
Thanks for your help cause i really need it.

I would suspect your jumpers settings are wrong. These are cable select...try that not slave/master

  • Snow Leopard Server fails when I restart my Mac Pro

    I have a new Mac Pro that I've been running Snow Leopard Server on. When I restarted my computer it wouldn't boot up. It would only get to the screen with the apple symbol and the spinning dial under it. I had to totally reset up the computer and server software. 2 weeks later the same thing happened and I had to reset it all up again! A week later the same thing happened so I just gave up and installed Snow Leopard. I was using the computer as a "regular computer" meaning I had all my music, photos, other apps.... but nothing was installed or changed the day and the day before it failed. I didn't even have time to set up web hosting and all that crap. I was just browsing the web using Safari.
    And yes everything was up to date.
    I would love to go back to Server but I'm not going through all that crap again!!
    Any ideas for what the problem could be would be great!
    one last thing. Finder froze the last time which is why I had to restart; if that helps anyone.
    but please leave a message even if you think it wouldn't affect it.

  • When I restart my Mac, the grey screen appears like usual. But it takes more than 40 minutes (more) for it to load to finish restarting the Mac. What should I do?!

    Disconnect all devices from your computer if you have not already done so.  Restart again.  If the problem has been resolved, you had a peripheral conflict.  You will then have to reconnect the devices one at time, restart,  to locate the culprit.
    Login Items is another culprit.  Check your login items.

Will it go back to Leopard if I restore it from the backup?

    No, it won't revert to the prior OS X but you you may have third party apps installed that were compatible with Lion that may not be compatible with Mountain Lion.

  • I'm stucked on APPLE evolution bar when I restarted my Mac after upgrade to Yosemite. I Can't access on my computer.

    I'm stucked on APPLE evolution bar when I restarted my Mac after upgrade to Yosemite. I Can't access on my computer.

    Good Question.
    I downloaded Yosemite a while ago, but didn¹t install it because it would
    knock out several applications such as Solitaire till Dawn But finally
    when some apps wouldn¹t work with my current version of Safari I thought I
    would upgrade Safari but they wouldn¹t work with the OS I was using so
    suddenly I had no Safari and was worse off than before. So I bit the bullet
    and upgraded to Yosemite with the earlier version I already had. Not pleased
    when iPhoto didn¹t work, and it also coincided with an national email outage
    here in Australia by the major carrier so no email either.
    Experience has taught me that it gets sorted out in the end but in the
    meantime...

  • PRAM reset when I restart to Mac OS?

    I hope I posted this message at the right place...
    I installed vista, no pb. Sometimes - and that's the issue, it's not always - when I restart to Mac OS, the iMac restarts several times (several restart chimes), and the I get the gray screen with the Apple and the little loading logo.
    The clock is un-set, so it looks like the PRAM has been reset
    Is there a way to be sure that's what happens (PRAM reset)?
    How to avoid it?
    Is it bad for the computer?
    thanks!

    I should also mention, I have a 3rd hard disk with Windows XP installed (all of these are internal in the MACPRO). The same thing is now happening there as I have just checked. The Bootcamp control panel does not instigate to boot into Mac OS X either. So how can I get this control panel to write to the EFI (if this is what it is called?) to boot into the correct selected partitions? I should also mention I can see the Windows 7 and the The Windows XP respectively displayed in there. But I cannot get to boot into either of those either by selecting them from this control panel. It is stuck booting into it's own OS disregarding my selection. I don't think it is 'talking' to the EFI anymore and writing what it should to it (or to bootmgr or something)? What can I do in this case?
    What does bootcamp.exe actually do? If I could delete the current list it has stored and get it to rescan even though everything is exactly the same, just reinstalled Mac OS X by erasing the partition on the main drive, which I'm guessing this is why Bootcamp.exe does not write the appropriate command to boot into my OSes?

    WiFi signals get stronger the closer the machine is to the router and the less interference/blocking of the signal like via walls with metal in them or of thick concrete.
    Since the signal emanates outwards in a sphere, your supposed to place the wireless router in a central location in the building so it covers all areas.
    The power of the router also has a affect, if your router is old or something not that powerful like a Airport Express, it doesn't have the ability to filter out other signals or enough punch to get through walls etc. or cover a large area as effectively.
    If you buy/have a powerful router of newer make and have issues where there is metal in the walls or thick concrete, then you can buy something like OpenMesh and by using Ethernet cables from the back of the router, extend the WiFi signal into other rooms and areas past the blockage.

  • Even when I charge my Mac Pro to the full bar, the battery seems to be drained even when I am not using it. Example, after charging it full, i switched it on the next day and its 79% battery left. Is there something wrong? help please

    Even when I charge my Mac Pro to the full bar, the battery seems to be drained even when I am not using it. Example, after charging it full, i switched it on the next day and its 79% battery left. Is there something wrong? help please

    Assuming you are disconnecting from line power, when you say switched on, do you mean it was shutdown or in sleep mode?  If sleep mode the battery will still drain because sleep still keeps some things active and the battery does drain a little.  However, to go from 100% to 79% charge overnight is a bit excessive in sleep mode.  Unless you have some processes set to activate over night by the cron file and do things like backup the system.

  • When i active my mac pro all i get is a white screen and  it loading .. and when it fully loaded it turns off and the same thing keep on happening again

    when i active my mac pro all i get is a white screen and  it loading and when it fully load its turn off , and it keep on doing the same thing for hours

    Hi Shahenaz,
    It's a little difficult to understand exactly what's going on with your mac based on the description you gave. Is there anything else you could add? Is it stuck in a reboot loop? Or is it just showing a white screen forever?
    I had pretty much the same problem a few days ago, and was worried my mac was screwed permanently, but I got it fixed up no problem!
    Follow these steps to try and troubleshoot/fix the problem.
    1. Boot into OSX Recovery Mode
    First, turn off your Mac. If it isn't responding, or is stuck in a reboot loop, just hold down the power button until it turns off, and you hear the fans stop. Then boot it while holding the Command and R keys. If it successfully boots into OSX Recovery Mode, continue with this step. If not, skip to step two. (My Mac couldn't successfully boot into the recovery mode, so I had to go to step 2)
    Select "Disk Utility" from the list of options, and find your built in hard drive from the list on the left. Usually there are two listings/names for your drive. The first should be something like "500GB longchainoflettersnumbers Media". Then the one below will be a little easier on the eyes, named Macintosh HD, if you haven't changed its name. That's the one you want, click it.
    Now go to the "First Aid" tab. Click on the "Verify Disk" button in the bottom right corner, and let it do its thing. Once that's done, hit repair disk, also in the bottom right corner. If your disk is corrupted, you may need to run the repair process several times, before it comes up completely clean.
    Once this is done, select Shut Down from the Apple menu and, once your Mac is completely off, turn it back on like normal. If it works, great. If not, proceed to step two.
    2. SafeBoot
    Sometimes, when a mac is acting up and doesn't want to start, all it takes is a safe boot, followed by a regular restart. Or maybe you recently installed a program that either has malicious or errored coding that's causing your troubles. This is where Safe Boot comes in.
    Turn off your mac, and reboot it while holding Shift. (If you want to see the process that's going on in the background, boot while holding Shift, Command, and V. This will enter something called Verbose Mode).
    If it boots successfully into Safe Mode, great. If you believe that there's a particular program that you recently downloaded that might be causing your trouble, now's the time to delete it. If not, just reboot normally and see if it works! If it doesn't, or if your Mac didn't even Safe Boot like mine, proceed to step 3.
    3. Fsck!
    For this step, you're going to be booting your mac into Single User Mode. I'm not going to go into details as to what this step does, but it works for some people. Here are the steps.
    Turn off your mac, and reboot it while holding Command and S. The screen should go black, and you'll see some white text run across the screen, wait a few seconds, until you see the command prompt. Now type
    fsck -fy
    and hit the Enter key. This will run a series of system checks, which could take a few minutes. Be patient on this part. Once it's done, it will show one of two messages:
    1. "The volume (your Mac) appears to be OK
    or
    2. "File System Was Modified"
    If you got message 1, type reboot and press Return. Hopefully your computer works after this - if not, proceed to step 4.
    If you got message 2, run the same command again until you get message 1. If it doesn't seem to be working, turn off your system and proceed to step 4.
    If you couldn't even boot into Single User Mode in the first place (like me), go to step 4 anyways.
    Step 4: Reset the NVRAM
    The NVRAM is another kind of RAM that stores data like the computer volume you had set before you turned it off, or the screen brightness, resolution etc. This memory is saved, unlike with regular RAM. Resetting it isn't harmful to your system, it will just put your screen brightness, volume, etc. to defaults.
    Turn off your Mac, and reboot while holding Command, Option, P, and R, and continue holding them down until you hear the computer restart again.
    I can't really explain why to do this step, I just know it works for some people, and seems to be what unbricked my MacBook Pro. If none of these steps, fixed your Mac, well the situation is looking pretty grim. Try setting up a meeting with a Mac Genius at your local Apple store. However, I know that many other people with these symptoms ended up having a logic board failure. Apple can swap out your logic board for a new one, but the price is pretty hefty, somewhere around $300 I believe.
    Well I wish you luck, I hope this helped you!

  • When switching on my Mac Pro on bootup it keep shutting down then eventually it works fine

    When switching on my Mac Pro on bootup it keep shutting down then eventually it works fine

    I also have the exact same problem with my early 2008 Mac Pro.  Last spring, the video card that came with the unit burned out.  I brought it in to the Apple Store in my area, but they were unable to really help me out.  I ended up replacing the card, but about two or three weeks ago I started having the same exact issue that you do - the Mac would suddenly die occasionally, and then would take quite a few tries to come back up.  It seems that resetting the PRAM helps temporarily with me.  It has been up since about 3 PM so far, and it is behaving.
    My main issue is that replacement parts are expensive for this machine.  If I were to replace the power supply and the logic board, Apple would charge me about a thousand bucks!  That's simply too much money to drop on a 4 year old computer.
    My solution is that I will run it for a while longer, and replace it with the Mac Mini with the ATI GPU.  The Mini is about 85% as powerful according to Geekbench, and if it dies I will not be out more than a few hundred bucks.
    I will be migrating all my OpenCL code to FreeBSD as well, because replacing a power supply or motherboard in a generic DIY PC is only a hundred or two dollars at the most.

  • I replaced the battery on my RAID card, when I booted my mac pro up, I get the folder with the question mark. I used a boot USB drive to boot and when I looked in the RAID utility, my RAID 5 volumes were no longer showing, advise.

    Ernest

    Not sure if I'm following you. I have 4 hard drives installed on my Mac Pro. I had a RAID 5 configured and functional for about 5 months. My battery died on the RAID card. I replaced the battery, seated the RAID card back in the slot I removed it from. When I booted to the USB drive to look in the RAID utility, I could see the battery is charged but my volumes are not showing.
    The drives don't show in disk Utility. I built the RAID with the RAID Utility and they did show there. I have a early 2008 Mac Pro, Mavricks OS running Mac Server
