  • Mac Pro doesn't recognize any internal drive

    My Mac Pro (2008) -- after rebooting -- does not recognize any of the internal drives. I'm running 10.6.8 and all of a sudden after reboot, the machine hangs on grey screen and I get folder w/ question mark symbol. I boot from Snow Leopard install disk but no drive shows up as being able to reinstall on. Even opening up Disk Utility from Snow Leopard disc shows no internal drive.
    Any ideas?

    Just a few additional random thoughts on this Hardware:
    A SATA controller failure should take out all SATA drives. On the 2008 model, the Optical drives are IDE/ATA, but there are two additional SATA ports (data only) on the motherboard.
    In the 2008 and previous models, the Mac Pro RAID card uses a cable called iPass to intercept the essential signals to the four Hard Drive bays and route them through the RAID card. If that iPass cable were to come loose, the four main drive bays would stop working.

  • Mac pro doesn't recognize admin password

    Mac pro doesn't recognize administrator password on login, I am using Yosemite and I was using erlier and didint let me log back in password was correct at all times tries to reset password with apple id and still not working. Try disk utilities with terminal and disk is not available, when I updated from maverick to yosemite I didin't set up a disc recovery.

    when I updated from maverick to yosemite I didin't set up a disc recovery.
    There is no need to do anything to set up Recovery. It should have been created and updated automatically on your Boot Drive when you upgraded to Yosemite.

  • Mac Pro doesn't recognize USB 3.0 PCI express card

    Mac Pro doesn't recognize USB 3.0 PCI express card.  Does it need specific drivers? 

    I did a little searching for that card.  The more I looked at it the more I felt that, yes, it needs a driver, and no, one doesn't exist for the Mac.  So it looks like that is a card only supported for PC's. But to be sure, if I were in your place at this point, I would contact MSI directly.

  • Mac Pro doesn't recognize BluRay burner with Lion

    My Mac Pro would occasionally recognize my Blu-ray DVD burner, now with the Lion update, not at all.  My Apple Superdrive is recognized in Bay 1, but not the Blu-Ray in Bay 2.  Is there any way I can get my blu-ray burner to show up and be usable?  I have used Toast Titanium Pro to burn several BluRay discs before on this computer, but with Snow Leopard; even then, I would have to re-boot the Mac Pro in order to get it to remember it.

    Look back a couple months for a long thread on BR burners and support.
    Also, check and see what OWC sells and supports, and what 3rd party softare or from the vendor of course.
    Seemed like BR drive not being "present" after waking from sleep was one issue, or affecting sleep mode. Just like yours.
    I don't see that you include the make etc, you might consider that of interest.

  • My MB pro doesn't recognize any start up discs. I have the flashing question mark, but when I press option/alt, I'm only prompted to start the internet recovery. Afterwards the Mac OS X Utilities pops up, but there's no start up disc?

  • Mac Pro doesn't recognize Magic Mouse

    I have had a wireless mighty mouse without any problems but liked the idea of the magic mouse. The Mighty Mouse works fine and I've switched around the BT wires inside like many have talked about. However, when I try to setup the Magic Mouse, it isn't recognized at all. However, I can set it up without any problems with my Macbook Pro. Any thoughts?

    Good question. I have a PPC with a D-LInk bluetooth (DBT-120, Rev. C) and I can't get the Magic Mouse to pair with the Mac. I downloaded the latest version, and all I get is a blinking mouse light. D-Link companyt says their bluetooth was only developed for OS-X 10.4 (Tiger) and only worked with luck with OS-X 10.5 (Leopard). There are some problems with the bluetooth keyboard (won't send wakeup from sleep mode) but it hasn't had problems with the Mightly mouse.

  • HT1533 My MacBook Pro doesn't recognize any key during startup!

    I press and hold option, nothing. C, nothing. D, nothing. Of course, one at a time, on different startups. Nothing happens!
    Any ideas?
    Thank you.

    Keyboard works otherwise? Why are you pressing C and what do your expect to happen? Try holding down the command-r keys on boot up.

  • The thunderbolt outputs on my new power mac pro doesn't work

    Ttrying to use a new 3tb thunderbolt external HD and my Power Mac Pro doesn't see the drive but it works fine on my Mac Mini.
    Have had this computer less than 4 weeks.
    Any help?
    Tom

    The current Mac Pro does not have Thunderbolt ports, it has Mini DisplayPorts that are physically identical to Thunderbolt but only pass video signals. The Mac Pro that is coming out in December (small black cylinder) will have Thunderbolt.

    Ok, fair enough.  But since Job's death - Apple's control on leaks has been terrible.  I got the new iPhone, and I like it - but it hasn't made nearly as big as an impression as previous ones.  Because of the vast ammount of leaks.  With the iPad mini leaks, it's 99% sure to come out next week.
    Apple uses many manufacturers and it's massive also websites prefer to report on Apple whether true or false because it brings more hits.
    Amd by "others" I meant other people on iPads - not other devices/manufacturers.  It's possible to do so, I just want to know how.  I honestly don't think we'll ever be in a Post-PC era until all tablets allow us to use USB in the way computers do.
    No, USB is not the future, you missed the memo about cloud and wireless computing?

  • Connectiong an external thunderbolt hard drive to an older iMac via firewire to thunderbolt adapter, as my Mac doesn't have any thunderbolt entry?

    Is there a possibility to connect an external thunderbolt hard drive to my iMac (originally Leopard 10.5.8. upgraded to Snow Leopard 10.6.3) via firewire to thunderbolt adapter, as my Mac doesn't have any thunderbolt, but has two firewire entries?
    Would like to use the hard drive's big data stocking capacity of 8TB, but actual WD-HDDs of such a capacity have no more other entries than thunderbolt.

    Basically, no.  The Thunderbolt-Firewire adapter does not work "in reverse,"  meaning, you have to have a Thunderbolt port on your Mac in order to use it.
    Most Thunderbolt drives that I have seen also have a USB 3 port.  You could use that, but on on an older Mac that does not have a USB 3 port you will be limited to USB 2 speeds.

  • Macbook pro doesn't recognize camera on image capture

    My MacBook Pro doesn't recognize the built-in camera for a lot of my applications, including Image Capture. It doesn't show up anywhere in my system preferences. Any idea why this is so?

    (1)  Mac's built-in camera does not work with Image Capture.
    Image Capture works with external devices like scanners, some iOS devices, some cameras and RAM cards, etc.  Click this link for more info about Image capture and some of the apps that can work with your inbuilt camera.
    Click here for info about how to use Image Capture to transfer images from a connected external camera.
    For more info about Image Capture functions, see Image Capture > Help on your Mac or the Apple pages in this link.
    (2) To test for application-specific problems mentioned in the "How to Troubleshoot iSight " article, use apps like Photo Booth, QuickTime Player, iChat, FaceTime, or others intended to work with your Mac's inbuilt camera.
    (3) To test for user-specific problems mentioned in http://support.apple.com/kb/HT2090 the "How to Troubleshoot iSight " article, you must have more than one user account.  Do NOT use the "Guest" account.  Click this link if you need help creating new accounts for testing.

  • What can I do when I try to access a URL and get the message "MAC OSX doesn't recognize internet addresses starting with "c:"?

    I recently tried to download a pdf file from a website in the UK.  Up popped a message saying the website could not be accessed, followed by this message: "MAC OSX doesn't recognize internet addresses starting with "c:".  I was able to access the website easily (its domain was "www") and the page listing the pdfs, but could not download a pdf.  Of course," c:" appears not to be a valid domain name, but why would anyone use "c:" in place of a domain name in their URL?  And what can I do about the problem?  I'm using Snow Leopard 10.6.8 and Safari 5.1.10, but also have Firefox and Chrome loaded.  Thanks.

    An address starting with c: wouldn't be any kind of domain name. C: is the drive lettering system DOS and and later uses. By default, A: and B: are reserved for your first and second floppy disk drive. All hard drives are then named C: through Z:, if you have that many. C: is normally your startup disk.
    Anyway, their PDF file is incorrectly linked to a file directly on the C: drive of someone's computer. It's not going to work no matter what you do.

    in my new macbook pro retina I've a problem on window 7 64bit (bootcamp 4.0). the OS doesn't recognize the thunderbolt-ethernet adapter..

    The thunderbolt ethernet adapter works without issue on my rMBP with Windows 7. Did you download and install the Windows Support software? Did you refer to the Windows help regarding networking? Did you try a different adapter? What happens when you try to use Ethernet networking?
