Just bought a used mac pro and it has 4 video cards?

Hi all, I just bought a used mac pro and it has 4 Geforce 7300 GT video cards in it. Why would it have 4? Is it just to display on 8 monitors, or can OSX use the power of each card? Is there anything I can do to take advantage of these extra cards? sell them?!

No, OS X cannot combine the four cards. All they are good for is to connect 8 monitors. If you don't plan to do that then you're better off removing three of them (only the upper three.) This will save energy - roughly 50-75 watts per card - and the computer will be cooler.

  • Just bought a used macbook pro and it was wiped clean. how do I purchase Lion or maverick to start it up??

    My daughter just purchased a macbook pro and it was wiped clean. It says we need to purchase Lion. How do we do that? We can't find it in the app store

    It has a question mark inside the quick time logo everytime I click on it
    If you mean you are trying to play a file and the QT icon with a quesion mark appears in the display area, then this means the play has reached a programming disjunction and doesn know what to do—i.e., the player recognizes the content but something is preventing proper playback is telling the user it has a question as to how the content is to be played. In such cases you normally have to determine what content, what file container, and which player version is involved before you can decide how to best fix the problem.

  • Just bought a used Macbook pro, and now I cannot get Garauge Band, iPhoto, or iMovie without having to pay?

    Title Basically sums it up.. is there anyway I can get those apps without having to pay for them..?

    You and the original owner need to contact Apple Care and have the MBP released from his Apple ID. Then you can use OS X Recovery to erase the MBP, install the original version of the shipping OS X updated to the most recent  version available and install new versions of the iLife apps that you can then accept into your Apple ID used with the Mac App Store.

  • HT1338 I have just bought a new Mac Pro after my old one died after nearly 10 years. I have most of my music backed up on CDs, but when i load them into iTunes they are only identified as Track 1, 2, etc. Can I transfer from my iPod and how?

    Greetings,
    I've never seen this issue, and I handle many iPads, of all versions. WiFi issues are generally local to the WiFi router - they are not all of the same quality, range, immunity to interference, etc. You have distance, building construction, and the biggie - interference.
    At home, I use Apple routers, and have no issues with any of my WiFi enabled devices, computers, mobile devices, etc - even the lowly PeeCees. I have locations where I have Juniper Networks, as well as Aruba, and a few Netgears - all of them work as they should.
    The cheaper routers, Linksys, D-Link, Seimens home units, and many other no name devices have caused issues of various kinds, and even connectivity.
    I have no idea what Starbucks uses, but I always have a good connection, and I go there nearly every morning and get some work done, as well as play.
    You could try changing channels, 2.4 to 5 Gigs, changing locations of the router. I have had to do all of these at one time or another over the many years that I have been a Network Engineer.
    Good Luck - Cheers,
    M.

  • Hello, I just bought a 2013 Mac mini and I cannot get the sound to output to my Dell U2713HM monitor.  I went to sound output but even though my Dell shows up there when I select it there is no sound output to it.  I am using a mini DP to DP cable...

    Hello, I just bought a 2013 Mac mini and I cannot get the sound to output to my Dell U2713HM monitor.  I went to sound output but even though my Dell shows up there when I select it there is no sound output to it.  I am using a mini DP to DP cable...Any ideas? Thanks

    Hi Alxx911, and John Hammer1. After reading John's reply - " You can plug something into it's headphone jack. though" . I thought i'd try out of curiosity. I plugged in some headphones. I didn't expect anything to happen  and nothing happened. The audio jack is for the Dell soundbar which is optional.
    Here's a direct copy and paste from the users manual: Section About Your Monitor.
    Attaching the Soundbar AX510 / AX510PA (Optional) CAUTION: Do not use with any device other than the Dell Soundbar. NOTE: The Soundbar power connector (+12 V DC output) is for the optional Dell Soundbar AX510/AX510PAonly. To attach the Soundbar: 1. Working from the back of the monitor, attach the Soundbar by aligning the two slots with the two tabs along the bottom of the monitor. 2. Slide the Soundbar to the left until it snaps into place. 3.  Connectthe Soundbar with the DC power connector. 4. Insert the mini stereo plug from the back of the Soundbar into the computerís audio output jack. For HDMI/DP, you can insert the mini stereo plug into the monitorís audio output port.  If there is no sound, check your PC if the Audio output is configured to HDMI/DP output.
    This monitor has no speakers. (Like John Hammer1 mentioned). The no speakers feature was one of the reasons I chose this monitor.
    Good Luck !

  • I just bought a used Macbook Pro. How do I make the changes to make it personal. Example the iTunes comes up as the old user and I have to have his password to make changes on the laptop. Can you make any suggestions?

    Also I cant make a right click on the pad. Is that normal?

    Your first going to have to remove all your personal data off the machine to a external storage drive, do not use TimeMachine when it asks as this will copy the entire drive and is unnecessary at this time (also takes too long).
    You need to drag and drop copy your personal data folders (Music, Pictures, Movies etc) to a external storage drive, once done, unmount and disconnect this drive.
    Most commonly used backup methods
    Next your going to follow the Zero Erase and install method for your OS X version, either 10.6 or 10.7, here
    How to reinstall just OS X or erase/install OS X
    10.7 requires your AppleID and password to install, so make sure to have that ready.
    Once you reboot your into the real setup of OS X, which will require your name etc, so it's now your machine.
    Install your programs, iLife package is only free for the owner of the machine.
    If you have the 10.6 machine specific disks, then it's on there.
    If your using 10.7, then you'll have to purchase it from the App Store.
    Last, return your files from the storage drive, consider setting up a TimeMachine or clone on the external drive.

  • I started using LT 4 and I have a serial number, also upgraded to LT 5 and have a serial number. Now I just bought a new Macbook Pro and installed the LT 5, but it doesn't accept my serial number. Why?

    I started using LT 4 and I have a serial number, also upgraded to LT 5 and have a serial number. Now I just bought a new Macbook Pro and installed the LT 5, but it doesn't accept my serial number. Why?

    When you installed the Lightroom 5 on your MacBook, did it ask for both serial numbers. Since you purchased Lightroom 5 as an upgrade, you need both the serial number from your original purchase as well as the new serial number for Lightroom 5. If you have both of those numbers and they are still not being accepted then you will have to contact Adobe customer support for a solution.

  • HT201364 I just bought a new Macbook Pro and I'm not sure if I have the new Mavericks as my OS.

    I just bought a new Macbook Pro and under current operating system, it list OS X 10.9.1 as my current system and says I can update to Mavericks. Isn't 10.9.1 the newest OS for Mac? This is my first Mac and I'm not sure about the way it lists the OS systems in the "about this computer tab". I tried to update to Mavericks and it will not allow me to update, despite meeting all of the above requirements. Can anyone help me?

    Mac OS X 10.9 and 10.9.1 are Mavericks.

  • Just got a new mac pro and can't manage to set a password and keep it.  It keeps telling me I have the wrong password.

    Just got a new mac pro and can't manage to set a password and keep it.  It keeps telling me I have the wrong password.  I want to start over and I can't even get back in to do this bc it won't take any of my passwords.  How can I start over completely?

    You got a new laptop? try asking there or in Lion forum.
    If it has Lion, use the Recovery Mode boot Command-R
    Use that to erase and reinstall - it has network install ability.
    Want MacBook Pro forum or Lion Community?

    New, as in from Apple, it would have asked for full setup.

  • HT4796 Hi, I've just bought a new Macbook Pro and started migrating from PC but the remaining time is about 70 hours long, I just wanted to know if that timing is normal and if not, does leaving running my MacBook that time can affect it?

    70 hours...  no, it's not normal but it can't hurt your Mac to be running for that amount of time.

    Click here and follow the instructions. If the computer originally shipped with Mac OS X 10.6.8 or earlier, when you reach step 5, insert its original disk, restart with the C or Option key held down, use the Disk Utility to erase the internal drive, and install a fresh OS.

    I just bought a new macbook pro and my CS6 migrated, but now when I open existing documents, it launches a free trial version. There doesn't appear to be a way to enter my serial number or communicate that I simply have a new computer. HELP! There is no customer support for this. I can't believe what a poor service company Adobe is!!

    The problem was that you migrated CS6. Unfortunately, migration doesn't work because it doesn't move all the files.
    First, you'll need to use the Adobe Cleaner Tool to remove the components that were installed:
    Use the CC Cleaner Tool to solve installation problems | CC, CS3-CS6
    Second, you should install a clean copy of CS6. Here is a link:

    How is your external drive formatted? Use Disk Utility to check the volume format. If it is NTFS, you will need to reformat the HDD as exFAT in order to retain universal compatibility (RW to it on both Mac and Windows).

  • Hi all, i just bought the new macbook pro and just want to know if i can install Vista or Xp on it?

    Hi all, i just bought the new macbook pro and just want to know if i can install Vista or Xp on it?

    Yes.
    Windows on Intel Macs
    There are presently several alternatives for running Windows on Intel Macs.
    1. Install the Apple Boot Camp software.  Purchase Windows XP w/Service Pak2, Vista, or Windows 7.  Follow instructions in the Boot Camp documentation on installation of Boot Camp, creating Driver CD, and installing Windows.  Boot Camp enables you to boot the computer into OS X or Windows.
    2. Parallels Desktop for Mac and Windows XP, Vista Business, Vista Ultimate, or Windows 7.  Parallels is software virtualization that enables running Windows concurrently with OS X.
    3. VM Fusionand Windows XP, Vista Business, Vista Ultimate, or Windows 7.  VM Fusion is software virtualization that enables running Windows concurrently with OS X.
    4. CrossOver which enables running many Windows applications without having to install Windows.  The Windows applications can run concurrently with OS X.
    5. VirtualBox is a new Open Source freeware virtual machine such as VM Fusion and Parallels that was developed by Solaris.  It is not as fully developed for the Mac as Parallels and VM Fusion.
    Note that Parallels and VM Fusion can also run other operating systems such as Linux, Unix, OS/2, Solaris, etc.  There are performance differences between dual-boot systems and virtualization.  The latter tend to be a little slower (not much) and do not provide the video performance of the dual-boot system.
    See MacTech.com's Virtualization Benchmarking for comparisons of Boot Camp, Parallels, and VM Fusion.  Boot Camp is only available with Leopard or Snow Leopard. Except for Crossover and a couple of similar alternatives like DarWine you must have a valid installer disc for Windows. You must also have an internal optical drive for installing Windows. Windows cannot be installed from an external optical drive.
