Mac Pro is continually tries to connect to iMac

I have a Mac Pro that is constantly trying to connect to my wife's iMac. If her computer is not on, I keep getting an irritating message saying that her computer can not be found. If her computer is on, it constantly gets remounted on my desktop no matter how many times I eject it. This just started the other day and it seems to happen no matter what programs are running or if any are running at all.
I have checked to see if that computer somehow got put into my startup items but it has not. I have also cleared out the recent server list but that did not help.
Any help would be much appreciated.

Do you have any programs that keep the two in sync?
Does it happen form the time it is started, or does it start happening after a period of time or after starting a program?
Try starting with the Shift key held down. It will take a little while longer to start as it is running a file consistency check, but it will disable any startup items, also. If it doesn't try to connect when you boot like that into safe mode, then there is something that is being loaded at startup.

  • Using Mac Pro in Target Disk Mode Connected to MacBook Pro

    Hi all,
    I am trying to set up two macs to run off of the same monitors/keyboard/mouse/etc. I know about KVMs, but they are too expensive for my current setup.
    I want to know if it's possible to run a 2006 Mac Pro in target disk mode connected to a brand new MacBook Pro 13" via a firewire to thunderbolt converter.
    I would need to access the files, but also run the applications from the Mac Pro on the MacBook Pro.
    Would such a setup work? Would I have to reboot each time I wanted to switch machines? Would there be a significant lag in the Mac Pro's performance?
    Any tips or links to articles/etc. would be appreciated.
    Thanks,
    Nick

    Hi Niel,
    Thanks for the speedy response.
    I should have clarified that I know that I can access the drive like a firewire drive. I'm more curious as to whether I can either:
    1. use it's applications in target disk mode (based on your answer -- No, unless all the necessary system components are identical between the two computers).
    2. Boot from the Target Disk computer as if it were a separate drive of my main computer. If so, since this is Firewire and not SATA, will I notice a severe loss of processing power?

  • 2008 Apple Mac Pro with SAPPHIRE TRI-X R9 290 4GB GDDR5 OC (UEFI)

    Dear Apple,
    Can you please add hardware/drivers support for the Sapphire Tri-X R9 290 GDDR5 OC (UEFI) Graphics cards to the latest Mac OS X 10.10 operating system?
    We have a few Apple Mac Pro's that we installed older Radeon 7970 graphics cards in (a few years back) and now we are upgrading the graphics cards to the newest Radeon R9 290 Series cards (Sapphire Tri-X R9 290 4GB GDDR5 OC UEFI).
    We chose the Sapphire Tri-X R9 290 4GB GDDR5 OC (UEFI) (11227-00-40G) Graphics cards.  
    The Sapphire Graphics card can be found here:
    http://www.sapphiretech.com/presentation/product/?cid=1&gid=3&sgid=1227&pid=2091 &psn=&lid=1&leg=0
    We have been trying to figure out how to get this graphics card to work with the latest OS X 10.10 Yosemite.  We are installing two Sapphire R9 290 graphics cards per machine.
    We want to make sure that the OS X drivers support multiple monitors, CrossFire, as well as HDMI audio, and support GPU hardware support in the latest OS X 10.10 Yosemite.
    Has anyone managed to get the Sapphire Tri-X R9 290 (SKU ID: 11227-00-40G) working in a 2008 or 2009 Apple Mac Pro?
    We have 24 Apple Mac Pro's and we purchased 48 of the Sapphire Tri-X R9 290 graphics cards (to install into the Apple Mac Pro's) and we're trying to figure out how to add driver support to OS X for the Sapphire Tri-X R9 290 / Radeon R9 290 to the latest Mac OS X.
    If I go into the "Graphics/Displays" Hardware section it shows that the Sapphire card (in Slot 2) is installed, but it only displays the name "Display".
    The properties of the Sapphire Tri-X R9 290 graphics card are:
      Vendor: ATI (0x1002)
      Device ID: 0x67b1
      Revision ID: 0x0000
      Kernel Extension Info: No Kext Loaded
    Any ideas as to how to install hardware drivers to get these graphics cards to work properly in OS X 10.10 Yosemite and to enable GPU hardware support in OS X and also enable HDMI Audio?

    Over a YEAR has passed, and we still can't get Apple to add the latest hardware drivers for the newest/latest AMD Graphics Cards (AMD R9 290 series).
    We have contacted AMD, and Sapphire, and everyone has pointed their fingers back at Apple, and said that Apple is the only ones that can add the latest graphics drivers to their Apple OS X Operating System.
    So the problem lies on Apple, and Apple refuses to update it's operating system to support the newest/latest hardware.
    AMD pointed us right back to Apple and said that it's Apple's OS X Operating System, and that it's Apple's job to add and write the newest/latest graphics display drivers to their OS X operating system.
    AMD says it's Apple's fault.  Sapphire says it's Apple's fault.  Apple just refuses to do anything, and ultimately it's Apple's operating system and Apple's closed-ended ecosystem that refuses to allow customers/users to upgrade their Apple Mac Pro computers to the newest/latest hardware.
    In the end, I guess the only solution is to abandon Apple Mac Pro products, and just start purchasing "Microsoft Windows PC" computers that we can upgrade and that have PCIe slots that we can just swap out the graphics cards (every year) with the newest/latest graphics card hardware.

    Apple seems to be a "dead end" and they don't support their high-end customers and don't seem to support Apple Mac Pro (high-end) users.  Apple only seems to be concerned about selling iPods and iPads and iPhones, and they've abandoned their HIGH-END Apple Mac Pro users that want HIGH-END workstations for professional use.
    I guess if you want a high-end workstation, you have to go back to buying a Microsoft Windows PC, and start going back to using the Adobe suite, and just completely abandon Apple and Apple products all together.  (Apple is not in the business of designing or selling "high-end" products anymore).  Apple just designs low-end "overpriced" hardware, that you can't upgrade, and must toss in the garbage every other year, because you can't upgrade it.
    Apple has been heading this way for years, and the newest/latest "Black Shiny Trash Can" (that is NOT upgradeable and has no upgradeable PCIe slots and no way to even upgrade the video cards) and Apple has turned into a "disposable" computer company/business that just builds "All-In-One" garbage computers (that become extremely outdated and must be thrown away every other year, because they are not upgradeable) and you can't swap out video cards using standard COTS (Commercial Off The Shelf) latest Graphics Card adapters, and we can't even get the latest Mac OS X operating system to support the newest/latest graphics display hardware, it seems like our only choice (as others have stated before) is to abandon Apple products and begin moving/migrating back to Microsoft Windows 8.1 Pro machines.
    We can't get Apple to support their customers or update their operating system or support the newest/latest hardware in their operating system, so it seems to be a "dead end" ecosystem, and Windows 8.1 Pro and using standard PC hardware is probably a much cheaper/affordable route and it's a long-term solution, because Apple seems to come out with one nice product (every ten years) and then they don't support the product or it's users, or don't follow-up with Apple OS X operating system upgrades, and then you are stuck with very old outdated hardware because you can't even get the newest/latest drivers for the latest graphics cards/hardware.
    The only solution is to boot directly into Windows 8.1 Pro, and use Windows drivers, but then why even own a Apple Mac Pro if we can't use Apple OS X and can't even use our OS X software, and the only solution is to use our Apple Mac Pro as a Windows PC?
    We're really disappointed in Apple and how Apple fails to update Apple OS X and fails to support the latest graphics cards (such as the AMD R9 290 graphics card).
    I think 2014 is the last year that we are going to deal with Apple.  Starting in 2015, as part of our 2015 New Year's Resolution, I guess we'll start e-baying our Apple Mac Pro equipment, or selling it (as salvage) and begin purchasing standard Microsoft Windows 8.1 Pro high-end workstations, and get away from the old legacy dead-end Apple garbage hardware and dead-end Apple OS X operating system.
    It shouldn't be this hard, just to get some graphics drivers released to support the latest graphics card (which has been out for over a year now).  The Radeon R9 290 graphics cards were out in mid 2013 (for over a year and a half, almost 2 years now...) and we are already coming up on 2015, and Apple still hasn't added drivers support for the R9 290 series graphics cards to it's latest Apple OS X 10.10.1 Yosemite.
    It's a shame, but Apple has really gone downhill over the past few years.  Nothing but really old and outdated hardware, and even their "latest" Apple Mac Pro is 2-3 year old hardware (that Apple is marketing as "new") and it's non-upgradeable, and you can't even run/install the latest graphics cards into it.
    Apple is dead-end and it's not a place for "high-end" users anymore.  I guess Apple doesn't care about it's "high-end" user market anymore, and is just interested in designing silly iPhones and iPods/iPads.

    my mac pro suddenly stops working (2011), connection to the monitor stops, but de tiny light on computer still on and all sound stops. what's the problem?

    When the display turns off, it is not clear whether the computer has halted, or whether the display subsystem has failed.
    Those tests determine whether:
    a) Your Mac software had stopped working  OR
    b) Only the display had stopped working
    If the pressing the Caps lock light on the keyboard lights the Caps Lock light on the keyboard, some software is still running -- your Mac has not halted.
    If pressing Control-Eject on the keyboard, followed by the Return key shuts down your Mac, the software was still running.
    ¿Software was still running?
    --Yes, the problem is ONLY in the display subsystem
    --No, this is a computer-wide problem such as a kernel panic

  • 12 core Mac Pro does not improve render time over iMac quad core

    I'm rendering the same composition independently on two computers and they are basically rendering at the same rate, which is slightly better than 1 frame per second.
    The project settings and preferences are identical in each instance (with the exception of memory and multiprocessing, which I have experimented with ad nauseum). The composition includes no motion blur, no effects, just a couple of layers of chroma keyed .mov files (using keylight 2.0) and some still images. Neither machine is running any other applications, except occasionally Google Chrome, which seems to have no effect on performance.
    Both systems are running the latest version of After Effects CC (2014) and using the Classic 3D renderer.
    System 1 MAC PRO:
    Mac Pro 12 core 2.7 GHz Intel Xeon E5
    dual AMD FirePro 500D 3072 MB GPUs
    32 GB RAM
    OS X 10.9.4
    System 2 iMAC:
    iMac quad core 2.5 GHz Intel Core i5
    AMD Radeon HD 6750M 512 MB GPU
    8 GB RAM
    OS X 10.9.3
    As you can see, system 1 is vastly more powerful, and yet no combination of memory/multiprocessing settings can get the system to render faster than system 2.
    It doesn't seem to matter how much or little RAM I reserve for other applications (I have settled on 4 GB), or the number of CPUs I reserve for After Effects. The one setting that has improved performance is turning OFF render multiple frames. And even then it only brings the performance of the Mac Pro up to par with the iMac. I have cleared my cache, rebooted the computer, and read everything I can find online regarding the optimization of render settings.
    Here's a comparison of the respective CPU Loads:
    iMac
    Mac Pro
    With such a low CPU load, After Effects is obviously not utilizing the resources available to it on the Mac Pro. What a waste.
    Can anyone help?

    There's plenty of debate about the new Mac Pro vs a kitted out iMac.  Benchmarks show that some iMac After Effects processing can actually be faster than on a Mac Pro, depending on the content and some other factors.  If you're using software that has been optimised for the Mac Pro's GPU-centric architecture, like Final Cut Pro X, you will see great benefits.
    mac pro vs imac
    In my own facility recently we opted out of purchasing Mac Pros this year, and bought top-end iMacs instead.  The benefit to cost ratio simply didn't make sense for us right now.  Mac Pros are awesome machines, but a significant component of their cost is the dual GPUs, which are simply no benefit to After Effects.
    Reports say that the After Effects engineers are working on a major revamp of the After Effects processing system, so I'm betting you will realise far greater benefits from your Mac pro in coming AE versions.  For now, you may continue to see performance that is not spectacularly better than a souped-up iMac, depending on the type of processing involved.
    I've seen a few benchmarks that suggest the 8 core systems give better bang-for-buck than the 12 cores.  Try reducing your processors to 8 in After Effects and see if it makes a difference.  With 8 cores, allocate 3GB of RAM per core to leave some RAM for the OS.

  • Trying to connect my iMac to on 10.8.2 with PowerBook Intel on 10.5.8; sharing works from PowerBook to iMac but not the other way around. Why?

    Trying to connect my iMac to on 10.8.2 with PowerBook Intel on 10.5.8; sharing works from PowerBook to iMac but not the other way around. Why?

    Thanks for the interest. Preferences are similar on both machines: screen sharing, file sharing, printer sharing & scanner sharing all ticked and radio button for Screen Sharing is ON.
    My confusion is that I can get a network connection to the iMac by selecting "go to server" on the PowerMac running 10.5.8 but am unable to make the iMac connect to the PowerMac using similar selections. When ethernet cable is plugged in the PowerMac shows up on the finder bar on the iMac, but it does not allow either screen sharing or connection to occur - a dialog box tells me to check System Prefs and Network connection.
    I'm hoping to export a large file of photos from iPhoto on my iMac to my wife's PowerMac and hoped to achieve this with an ethernet network connection.

    The MacPro is a tower aimed at professional users. The display is sold separately. The iMac is an all-in-one aimed at consumers (and, well professionals, actually). The computer is built into the same housing that holds the display, optical drive and hard drive. It includes a keyboard and mouse (or trackpad).

  • Mac Pro does not stay consistently connected to internet

    Okay, I will try to be as detailed as possible...
    I recently moved and had a new internet connection set up. The company replaced the modem and router I previously had (against my will) with their modem/wireless router combo. My Mac Pro has a wired connection, while all other devices (iPods, iPhones, PC laptop, etc.) in my home are wireless. The wireless devices all work consistently fine, however, the Mac does not. Typically, while having network diagnostics open, I reset the modem and everything is fine. After a few minutes, or after closing diagnostics, it no longer works again. Today, even after restarting the modem and getting all green lights, it doesn't seem to connect at all.
    I have Windows installed under boot camp and the connection there works perfectly fine. This tells me there is an issue within my OSX settings, and not the equipment or connection. After learning this, my cable company's tech support basically told me to get lost and contact Apple. Though I'm paying them an obsene amount of money for crappy internet service, they really could care less about ensuring that their products at least work with their customers' equipment (they even told me they're tech support is unfamiliar with OSX).
    I'm guessing something in my network settings is causing this, but I don't have enough in-depth knowledge about this particular subject to troubleshoot it myself. I'm desperate for a good samaritan to help as my business can no longer operate until I have working internet access.
    PLEASE HELP ME!!!!

    Disable the router function in the modem they provided and you can continue to use yours.
    Modems, esp. cable, you may be able to return it.
    There may be a list of modems that are compatible on their service - even some that aren't listed will be like SB6121.
    And are you paying a monthly fee for their modem?
    Others have "commented on" the Mac Pro not negotiating as well. But it was when you used your own router, right ?
    I am totally sold on
    having modem and router separate
    Netgear routers - got the WNDR3400v2 last year and thinking about the next level, the R6300 probably this fall. I can even configure and monitor from iPad, iPhone, Android and their desktop app (Win and Mac).
    I wonder if like my ISP they have a support forum, I'd be lost w/o. They can check the modem remote login and see what the modem is logging (over my head).
    Had some odd electrial spike - 3x in a minute going onto UPS but not an outage. Spikes? left their modem 50% function and semi-crippled. I had to reset modem or it would reset itself I should say every 5-10 minutes at times. ISP could not tell until they got there. Then they found the modem was unable to connect to their activation page and had to replace it and the drop point on the telephone pole 70 ft away.
    I now keep a spare modem of my own (SB6121) and continue to use theirs, Cisco.
    You do have the ability to use your router, just not double-NAT is all.

  • Why are the Mac Pro's dropping their server connection over a PC network.

    This seems to be a common thread on the discussion, but I can't find a resolution. I have a mix of G5s and Mac Pro's all running 10.4.10. All the machines are set to manual 100BaseT Duplex. The Mac Pro's constantly drop their network connections or show write errors when you are trying to save. Can someone point me in the direction of the answer? thanks.

  • Mac Pro won't recognize ethernet connection

    My Mac Pro won't recognize the Ethernet cable when it's plugged in. I know the cable and connection are good because my MacBook Pro recognizes it with no problem. I've had it for around a year, but have always used the airport to connect to the internet. It has two Ethernet ports on the back and I've tried both. Is there anything I need to do to configure the NIC card?
    Thanks in advance!
    Ryan

    No, but you do need to configure the Ethernet port in Network preferences. Open Network preferences and select the Ethernet port. Click on the Advanced button then on the TCP/IP tab. Set the Configure IPv4 drop down menu to DHCP. Set the Configure IPv6 drop down menu to Off. Click on the Apply button. If all is well you should see a valid IP address in the network settings for the port. If you see an IP address starting with 169., then it means your Ethernet port is not getting an IP address from your router. You should have an Ethernet cable connected from the Ethernet port on the computer to one of the LAN ports on your router.

  • IPhone 3Gs, Mac Pro Internet sharing via Airport connection problems

    Hi, I have internet sharing turned on in my Mac Pro for the Airport connection and it works very well with laptops, but I have trouble getting my iphone 3gs to connect to it sometimes.
    restarting the iphones does not help
    stopping and starting the airport does not help
    I can restart the Mac Pro, but that can be a pain, but does usually allow be to connect again for awhile...

    I've been having the same problems as everyone else here. Trying to share internet connection from my ethernet wired iMac to my MacBook and my iPhone. Tried all the workarounds, but nothing works, or lasts very long.
    Yesterday, I finally talked with AppleCare for over an hour. All their suggestions (trashing preferences, changing settings, etc.) failed, as well. The AppleCare person then put me on hold to speak to an engineer, who told her that Snow Leopard no longer supports Internet Sharing as of 10.6.1.
    Not willing to accept that answer, I had them set up an appointment at the Apple Store Genius Bar for me, and after chatting with the Genius for a while, he also confirmed that Internet Sharing is no longer supported under Snow Leopard. Apparently, there were many hardware issues that the engineers decided to circumvent, and so did not include support for Internet Sharing with the internal airport in Macs. They said that the Airport it is intended to receive, not to send a signals! Yet, it worked fine, doing just that, under Tiger and Leopard! The only fix he could offer was to wipe my drive and take me back to 10.5, which I declined.
    However both the guy at the Genius Bar and the lady at AppleCare inferred that Apple "may" release another update to fix this issue, if they get enough complaints and bug reports.
    So, there you have it. Apple no longer officially supports Internet Sharing in Snow Leopard.
