My Mac Pro (1,1 Intel core) does not start up and the white light is blinking

Mac Pro does not start up, the white light is blinking. I check the conexion with the monitor and tried the monitor on another Mac Pro (5,5) and work correctly

When the Power light blinks in a deliberate pattern at Satrtup, that indicates not enough RAM, in full working order, is available.
You will need some known-good RAM to make progress.

  • HT4628 My ipad and iphone connect and recognize wifi signal, but my mac pro running 10.6.8 does not  recognize or list the wiifi signal as option, any ideas?

    Hi,
    In Austria, iphone and ipad "see" and connect to wifi signal no problem but mac pro in same room will not even allow me to choose the same wifi signal.  It seems almost blocked.  Havectried everything it seems by restarting, deleting preferred accoints, etc.  software is updated but running osx 10.6.8
    Thanks for any help!

    Try the basics first:
       Change your router channel number.  Most times this works & is all you have to do.
    Disconnect & reconnect your modem.  unplug it for about 10 seconds.  Plug it back in.  Do the same for Apple’s routers.  Wait for everything to reboot.
    System Preferences>Network
    Click the Assist Me button.
    In the next window that pops up, click the Diagnostic button & do the necessary.

  • Photoshop does not close files and the program does not quit.

    I have been on the phone with tech support for over an hour. Photoshop does not close files and the program does not quit. I am on a Mac and I am using Photoshop CC 2014.

    Have you tried uninstalling Photoshop CC and re-installing? Another thing to try is to remove all Photoshop CC plist files. There is also the Cleaner tool:

  • My iphone does not automatically switch off the display light when locked. How do I fix this?

    I have an iPhone 5 with iOS 8.2 software.
    My iPhone does not automatically switch off the display light when it is locked. Therefore, if I get an e-mail/text message/pop-up from other application, the light just stays on, which obviously drains my battery.
    The problem just started yesterday, and it has been a couple of days since I updated the software, so I wouldn't think the software update is the problem.
    I have tried restarting the phone (using home and lock button), but that did not work.
    Something else that seems weird is that once in a while, a blue beam rolls over the screen from one side to the other. I don't know why it does this, and have no idea whether this is related to the display light issue.
    I hope someone is able to help by telling me what to do in order to get my phone to act normal again.
    Thank you x

    Restart your device by holding the home and power button until the Apple logo appears. You will not lose any data.

  • Press Alt to popup Menu Toolbar, Click on a Custom Icon and the item does not come up AND the Tool Bar closes

    Options-->Menu Bar is Unchecked(off) (so, TABS are at the top of the screen):
    Press Alt to popup Menu Bar, Click on a Custom Icon and the item clicked on does not come up -and- the Menu Bar closes.
    So, Alt->Popup Menu Bar->Click a Custom Icon does not function properly.

    First off if you have Firefox4 you probably also have an earlier version such as firefox 3.6.15 installed. By default firefox installs these in slightly different locations, but it leaves it up to you to create a separate profile for each version. The profile is where firefox stores data and settings. I am not sure that firefox explains this clearly, but you will run into problems if you do not have a separate profile for each version of firefox. See http://kb.mozillazine.org/Testing_pre-release_versions
    To try to get the toolbars working correctly, after you have ensured you have separate profiles in use for each version ( the following action will make changes)
    # use the restore default set from the customise / customize toolbars dialogue
    # if that does not work then
    #* use [safe mode] and the option [X] reset toolbars and controls

  • Acrobat Pro X 10.1.10 Does Not Start Windows 8.1

    I have Create Suite CS6 which apparently bundles Adobe Acrobat Pro X.   I have upgraded to 10.1.10.    Under Window 8.1, this version simply does not start.   There is no startup screen.  There is no error in EventViewer of Windows.   It simply does NOTHING.
    I went to Windows Program and Features and did a "Repair" on Acrobat Pro X.  This redid the install but the result is the same.
    Is there a known compatibility issue here?   How do I work around this?

    Hello, 
    Have you tried to run the Acrofix patch on your computer?

    after installing the update the machine rebooted. But only the apple logo en circle appeared. and then....stuck.
    a hard shut down and reboot with Shift hold down until the bar did get it in safe mode (or was it the command V) but it freezes there....

    Another post did add some light to it too.

    Re: PROBLEMS WITH 10.8.5
    Sep 13, 2013 10:43 PM (in response to papanast)
    You might try this:
    Repair the Hard Drive and Permissions - Lion/Mountain Lion
    Boot to the Recovery HD:
    Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
    Repair
    When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list.  In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive.  If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported then click on the Repair Permissions button. When the process is completed, then quit DU and return to the main menu. Select Restart from the Apple menu.
    Then download and install: OS X Mountain Lion Update v10.8.5 (Combo).

  • Lightroom cc does not start. logout and login in creative cloud does not help. Have a test account, 2 days more to go (and want to decide whether to buy PS & LR CC or to stay with current desktop solutions.)

    I installed lightroom cc. But it did not start. Tried the solution, that seemed to help many others (logout, login) but it did not help. Even did logout, restartet pc (win 8.1, 64) and logged in again. tried to log out and log in in the cloud panel and in photoshop cc. nothing helped.
    Maybe it has to do with the fact, that i have a test account and only 2 more days to go? but i need to launch lightroom cc first before i can decide to purchase CC.

    Thanks for your reply. I was able to find help through a tech support chat session and the person helped me edit my /etc/hosts file and it solved the problem.
    For anyone else experiencing this issue (Mac OS X):
    Close all other programs and sign out from the Adobe Desktop App
    From the Finder, Go > Go to Folder...
    Type /etc and hit enter
    Find "hosts" file (only "hosts", there were similar files such as hosts.config but only open the one that says "hosts"
    Open the file, and replace the entire content with ### Host Database## localhost is used to configure the loopback interface#
    Close the file, sign back into the Adobe Desktop App
    Problem solved!
