HT5815 Screen flicker started after supplemental update to 10.8 5 on my 2012 mac mini

The problem monitor was one of 2 Dell S2740L and is connected via a mini DP to HDMI cable
The 10.8.5 supplemental update came with the iTunes 11.1.1 update
The screen would soften and flicker every few seconds and sometimes black out
Tried lots of fixes including another cable but nothing worked
Restoring back to previous know good version has solved the problem
Looks like fixing someones flicker problem has started another

Sorry - never mind.  I realized that my version of Java needed to be updated.  Once I did that, it connected just fine.

  • Black screen on start after update to OS X 10.10.3

    Hello,
    I updated my Mac Book Air to OS X 10.10.3 and now when I start it the screen is black and after several seconds I get the password screen.
    My Mac Book Air is a mid-2013, FileVault is activated.
    This behavior started after the update to 10.10.3, and FileVault was already activated.
    Could you please give me some help to find a solution and have my Mac Book Air work normally as before?
    Thank you all for your help.

    Hello again,
    I found a trick in order to get my Mac Book Air start normally.
    Here it is:
    1. I deactivated FileVault.
    2. Once the FileVault deactivation process completely terminated, I switched off the Mac Book Air.
    3. I restarted the Mac Book Air, it started normally.
    4. I reactivated FileVault.
    5. Once the FileVault reactivation process completely terminated, I switched off the Mac Book Air.
    6. I restarted the Mac Book Air, it started normally with FileVault activated.
    Well, I solved the issue by myself, but I think this should not have happened.
    Maybe the problem is that the update process had not been set for a Mac Book Air with FileVault activated?
    I hope someone from Apple will give me/us an explication for that issue, and it would be a good thing that this situation does not arise again for next OS updates.
    Best regards.

  • HT2693 My UPAD lite does not start after recent update. I have lots of info in it. Can anybody help me to get it back. Can I get the update out somehow? Thanks

    My UPAD lite does not start after recent update. I have lots of info in it. Can anybody help me to get it back? Can I somehow undo the update? Thanks

    "UPAD lite?"
    I expect that you mean some version of iPad.
    First, try a system reset.  It cures many ills and it's quick, easy and harmless...
    Hold down the on/off switch and the Home button simultaneously until the screen blacks out or you see the Apple logo.  Ignore the "Slide to power off" text if it appears.  You will not lose any apps, data, music, movies, settings, etc.
    If the Reset doesn't work, try a Restore.  Note that it's nowhere near as quick as a Reset.  Connect via cable to the computer that you use for sync.  From iTunes, select the iPad/iPod and then select the Summary tab.  Follow directions for Restore and be sure to say "yes" to the backup.  You will be warned that all data (apps, music, movies, etc.) will be erased but, as the Restore finishes, you will be asked if you wish the contents of the backup to be copied to the iPad/iPod.  Again, say "yes."
    At the end of the basic Restore, you will be asked if you wish to sync the iPad/iPod.  As before, say "yes."  Note that that sync selection will disappear and the Restore will end if you do not respond within a reasonable time.  If that happens, only the apps that are part of the IOS will appear on your device.  Corrective action is simple -  choose manual "Sync" from the bottom right of iTunes.
    If you're unable to do the Restore, go into Recovery Mode per the instructions here.

  • Firefox will not start after interrupted update to 5.0

    Lenovo x200 | Windows 7 32bit | Firefox 5.0
    I was updating Firefox from version 3.6 (I think) to 5.0. Simultaneously I had done a update on Windows that seemed to have stopped. The update of Firefox had also come to a stop. As I remember it the installation was complete, and I was attempting to start the program, when Firefox was checking compatibility with installed plug-ins and so forth.
    The Windows updates installed fine afterwards but after several reinstalls of Firefox, I still can't seem to get it to start.
    There is no error message or notification at all when trying to start Firefox.
    One processes is created, staying steady at 50% CPU and 26 404 K memory.
    If i try to open another instance of Firefox I get a process that takes 0% CPU and about 1 844 K memory.
    Summary:
    Firefox fails to start after interrupted update to 5.0 from 3.6.
    There is no error message.
    Firefox never starts (and the process never shuts down), just shows in the Task Manager under Processes steady at 50% CPU and about 26 000 K memory (I've seen it do this for at least 20 minutes, before terminating it).

    Thanks kenton. But now pop-up says beta 5.
    The ''real issue'' is what is going on. On one machine the update process works, but on my other machine it does not.
    The machines are identical IBM T60s with Windows XP.
    This is a real mystery, as well as being annoying.
    A clue or suggestion any one?

    Photos/videos in the Camera Roll are not synced. Photos/videos in the Camera Roll are not touched with the iTunes sync process. Photos/videos in the Camera Roll can be imported by your computer which is not handled by iTunes. Most importing software includes an option to delete the photos/videos from the Camera Roll after the import process is complete. If is my understanding that some Windows import software supports importing photos from the Camera Roll, but not videos. Regardless, the import software should not delete the photos/videos from the Camera Roll unless you set the app to do so.
    Photos/videos in the Camera Roll are included with your iPhone's backup. If you synced your iPhone with iTunes before the videos on the Camera Roll went missing and you haven't synced your iPhone with iTunes since they went missing, you can try restoring the iPhone with iTunes from the iPhone's backup. Don't sync the iPhone with iTunes again and decline the prompt to update the iPhone's backup after selecting Restore.

    hello, this is a scam tactic that is trying to trick you into installing malware, so don't download or execute this kind of stuff! as you've rightly mentioned, you're already using the latest version of firefox installed and you can always initiate a check for ''updates in firefox > help > about firefox''.
    you might also want to run a full scan of your system with the security software already in place and different tools like the [http://www.malwarebytes.org/products/malwarebytes_free free version of malwarebytes], [http://www.bleepingcomputer.com/download/adwcleaner/ adwcleaner] & [http://www.kaspersky.com/security-scan kaspersky security scan] in order to make sure that there isn't already some sort of malware active on your system that triggers these false alerts.

  • After rebooting late 2012 Mac Mini a question mark appears on screen

    Hi guys,
    After rebooting my late 2012 Mac mini model No A1347 I have a question mark inside a folder always when i try to start my Mac Mini. I understand that I need to reinstall Mac OS X, but I have tryed holding the command, option, R and P keys and nothing happens... I also think the wireless keyboard is maybe not sincronised with the computer, maybe?
    I am clueless in how to proceed.
    Offcourse, there is no DVD drivein the new mac minis so i can't just reinstall it from a CD.
    Please help!!!
    Thank you!!

    You need to press either the Option key or the Command and R keys. If this doesn't work with the wireless keyboard, use a wired one.
    If you can get it booted to a normal Mac OS X system, select that system in the Startup Disk pane of System Preferences.
