Mac divider has changed

hi can u please help me i am runing os 10.8 and my mac divider in the dock has changed to the old one please help i want the new one back

Dear all,
I am having the same problem with a new MacBook Pro, bought end of October - for me it became apparent for software (Matlab, Comsol) that are registered with a licence file which was created based on the MAC address, and also when trying to register the computer to the company network. That software will only work those times that the computer "knows" its real MAC. Also, I found that audible audio books, managed through itunes, will not synchronize with the ipod at those times when the MAC address is at the producer's default (00:10:15:00:00). I never had network issues other than this computer registration, - no probs at home or elsewhere - , so it will depend on the individual setup which issue users observe.
I have had long phone discussions with different Apple support people, they have done checks based on Capture Data that I sent to them via email, etc.. They can't find the problem in the software/setup and they advised me to go the Genius Bar and have those guys look at the computer's guts.
Restarting sometimes did set the MAC to the real one, also running the code that someone suggested in Terminal sometimes helped.
Other than that, looking through the web, it does not seem to be an Apple-unique problem, but certainly one would like to see support to take care of that issue for Macs soon.
Also, thanks a lot for this thread! Otherwise the support guys on the phone would not have believed my : "the Mac address changes on a daily basis" and would just have brushed me off.
All the best,
Susanne

  • Ethernet MAC address has changed and I can no longer connect to the network

    I have a new iMac, 21.5" running 10.6.4. It was purchased in the past month.
    I am using it on an ethernet network and using DHCP to obtain the address. It has been working for the past few weeks. I turned it on today and it is failing to connect. After some digging around, it seems that the MAC address (Ethernet ID) has been reset to 00:10:18:00:00:00. This is different to the one it has been using last week.
    I have not changed any network settings. Airport is working fine.
    If I pull out the ethernet cable and reinsert, the machine tries to obtain an IP address. After a while, it returns with a self-assigned IP Address.
    Last week, I did notice that it was taking a relatively long time (a minute or so) to obtain the IP address over ethernet. Plugging the same ethernet cable in a macbook, I am able to obtain the IP address for the macbook much more quickly.
    I see that I could use ipconfig to change the interface address to what I believe is the correct address. Would this be sensible?
    Why would the machine have reset the MAC address anyway?
    Regards,
    Neil

    Hi,
    I have an iCloud account on my Mac which has a different account name to the iCloud account on my iPhone. How can I change the Mac account name to match the iPhone one? Kuranda.

    You can't change it in one step. Sign out of the one now on the Mac, sign onto the right one.

  • When i double click on Mac HD the view has changed and my user name is no longer listed on the left. How can I reset this

    When i double click on Mac HD the view has changed and my user name is no longer listed on the left. How can I reset this?

    Do a factory reset .. nothing will be deleted from your backups and you will be able to get access to them again.
    The Factory Reset Gen1-4.
    Unplug your TC. Hold in reset. and power the TC back on.. without releasing reset for about 10sec. When the status light flashes rapidly; release it.
    Be Gentle! Feel the switch click on. It has a positive feel..  add no more pressure after that.
    TC will reboot after a couple of minutes with default factory settings and will wipe out previous configurations.
    No files are deleted on the hard disk.. No reset of the TC deletes files.. to do that you use erase from the airport utility.

    I have posted in Mac pro Eplehust and Oslo in early June to change videokart (which has changed six months ago) got my Mac a month by mail, with the terrible damage the body, but the packaging in which he lay was not damaged. I sent him back to change the computer, 4 weeks, I changed it and checked 2 more weeks. as a result of three days ago, got back, more than half the programs crash, I can not open or closed CDrom, some programs do not come off or stop, and stop responding commands, turn it off only mechanically, not any excuses, I did not get to the store, what should I do?
    My patience is crowded, nerves on edge, I have lost my time with the worst service of my life, the only thing I see its the draw Eplehuset and apple to court.

    While writing I made a mistake... It is true I could become aware of the Scorpio incompatibility.
    I also tried the same identical procedure with a Seagate one. This disk and the same procedure was performed by some people I know on many MacBookPro Mid-2010 and everything was OK.
    We do not understand why this problenm occurs.
    Furthermore, If I installed the system on the broken HDD (that works, but sometimes it fails so badly and makes the system experience kernel panic) I could boot from it.
    I guess it is because of the **** Apple FIrmware written on the label.
    Is it possible that I cannot manage to boot from my new HDD because it has not a "special" feature on it that makes it compatible with apple??? Why making things so **** difficult my god a closer world like Apple one is impossible to imagine.
    However Shootist007 thanks for your message, but given what I said I do not think is a cable problem.

    Start Firefox in <u>[[Safe Mode]]</u> to check if one of the extensions or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).
    *Don't make any changes on the Safe mode start window.

  • What do I have to do in creating a Keynote presentation on my MAC so that when I send it to my iPad, I don't have to re-do the presentation all over again as the fonts have changed, sizing has changed and everything is basically a mess?

    What do I have to do in creating a Keynote presentation on my MAC so that when I send it to my iPad, I don't have to re-do the presentation all over again as the fonts have changed, sizing has changed and everything is basically a mess?
    I have downloaded many of my previous Keynote presentation into my new ipad mini and not ONE has opened properly
    Rather defeats the purpose of icloud, synching, Keynote on IOS etc doesn't it?
    Any tips anyone?
    Cheers
    Philip

    Thanks for this Gary. Much appreciated. Will help with future ones.
    Still a bit like using keynote in 'safe mode' and very limiting.
    If anyone produces an 'auto convert' app that will save me the work of fixing existing presentations slide by slide, I'm buying it :-)
    Thanks again

  • Macbook pro now says itunes not supported on this type of Mac.  only change has been addition of Apple TV. how to fix?

    My older macbook pro now says itunes not supported "on this type of Mac".  Only change has been addition of Apple TV. The Apple TV remote is also controlling the Macbook.  Is this the problem?  How to fix?

    Did you recently update OS X? The icon indicates you have a version of iTunes that is not compatible with the version of OS X you now have installed. The current version is Apple iTunes 11.0.2, and it's compatible with 10.6.8.

  • My projector no longer recognizes my mac.  It always worked before, but last week, it would not detect a signal.  what has changed?

    I have been doing powerpoint presentations for 3 years.  No problem.  Last week, the projector did not recognize any signal coming from my Macbook.  It recognizes two other Macbooks, so I don't think it's an issue with the cable.  I'm guessing something has changed on my settings, but I have no idea what!!!!

    Thanks for the response, and sorry for the delay on my end. This seemed to resolve my problem as well. I had no idea about a device manager. To find it, Right click My Computer, then click Manage, then find and click Device Manager under System Tools. In my case, my computer recognized the devices and the drivers, but still indicated a problem. So I finally uninstalled the devices (Right click / Uninstall), then installed them again. The X-Fi did not software for this. For my Micro, I used the original CD. I believe this all of the drivers and software are on the Creative site as well. I still have no idea what happened, but everything works and I am satisfied. Thanks for the lead.

  • I have an iPad 2 v6.1.3 that has a problem with connecting to wi-fi.  My other I macs have no problem with connecting.  The pad keeps coming up with unable to join the network. Nothing has changed with passwords--it just refuses to join my secure network.

    My other Imacs and my wife's Ipad 3 have no problem with conneccting.  My Ipad keeps coming up with unable to join the network.  Nothing has changed with passwords--it just refuses to join my secure network.  A couple minutes ago, it connected for 10 seconds, then dropped the connection.  Is there a way to reconfigure the Ipad to fix this major problem, as we dropped our carrier (saved a bunch of money) and just went wifi.
    Thanks so much for any help with resolving my connection problem.
