Black Screen with white text at startup (??)

Hello All:
I have a 2010 15" MacBook Pro, just got it in June. Had to send it in for a logic board replacement and now have it back. Everything works great except now instead of having the standard Apple greyish startup screen, I have a black screen with white text that scrolls through all of the startup stuff. I figure they changed some line on a plist somewhere so they could watch the startup and make sure everything was OK, then forgot to change it back.
Although I know it is good to know what's going on under the hood, I would rather it started up the regular way. Anyone know how to switch it back? I would call Apple, but would rather not sit on the phone for a long time for what I believe is probably a very simple fix. I did a search but couldn't find my problem listed....
Thanks everyone...

Kappy:
Thanks for the reply. I looked at the plist, but the -v was not there. Here is a copy of the plist:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
<key>Kernel Flags</key>
<string></string>
</dict>
</plist>
At least I know what it is called now - a "verbose startup".
Again, thanks for the help. Learn something new every day.

  • Macbook Pro boot shows black screen with white text cursor

    Hello,
    I have a MacBook Pro 7,1 MC374xx/A running Mavericks.  My box has two internal hard drives in it.  One had the Mac OS installed to it, and the other has absolutely nothing on it.  I decided to give Boot Camp Assistant a try and chose the hard drive with nothing on it to install Windows on.  I also had an external USB DVD drive attached with the Windows 7 installation disc on it.
    So, next thing ya know, my Mac reboots and loads a black screen that says "Memory Overload." I take out the external USB drive and restart.  Then it said, "No boot devices found."  Now for whatever reason, it's just a black screen with a white text cursor.
    What the heck happened?
    I selected command R and confirmed that I installed Boot Camp on the right hard drive (the drive that did not contain my Mac OS).  Then, I completely erased everything from the drive with Boot Camp on it.  But still..black screen with white text cursor.
    I have no Time Machine backups available so I'm forced to reinstall the OS.  Any idea why this happened?  It seems I must have attempted to install Boot Camp improperly.  Any ideas or instructions on what to do now or how to install Boot Camp successfully on the Macbook Pro I own?
    Earnestly,
    Speck

  • Black screen with white text on boot

    Hi, When I boot my mac I see the apple logo for a few seconds. after that I see a black screen with white text then the computer starts up. What is this and how do I fix it?
    Any help appreciated

    Hi
    This is "verbose mode", which is a boot-up mode used mostly for troubleshooting the boot process. Sometimes your system can get into that mode accidentally. Try this: boot up holding down cmd-opt-O-F (to get into Open Firmware). Type:
    reset-nvram
    reset-all
    Your computer should restart; reboot it once more to see if you are now booting normally.

  • When I boot up my iMac I get a black screen with white text?

    Hey guys wondering if anyone can help me. I installed mountain lion on my iMac the other day (2.8ghz Intel Core 2 Duo, 24inch) and now when I turn it on I get this screen come up? Any one no of a way to fix it? It comes up black all this white text appears and at the end it says..

Its strange cause ML is running fine on my macbook air. If anyone has any suggestions I would be so grateful. Tell me this isnt the end of her?
    Its not something silly like the keyboard and mouse aren't connecting? I leave them on all the time.
    Heres a snap of the screen
    Thanks everyone

    I did reset the PRAM, but don't think that worked.  I did find this on a blog on the web.  It worked for me
    When I first read this post I did not realize that the Mac boots properly if you type "exit". It seems like perhaps your mac thinks you want to boot in "verbose" mode. Try this before doing a reinstall.
    http://www.ernieflores.net/osx-page-3/always-boot-mac-os-x-in-verbose-mode/
    I got this info from here
    http://www.mac-forums.com/forums/os-x-operating-system/280859-black-screen-white -text-startup.html
    note: after it starts with the white text and black screen just type exit then hit return key and the computer will startup.  open the terminal after that and follow the ernie flores blog tip.

  • Black Screen and White text at startup

    Greetings, I recently installed the latest security update so I don't know for sure if this is the cause or a coincidence. When I startup my iMac G5 1.8Ghz PPC I now get a black screen with a lot of white text instead of the ususal grey screen with the apple logo. The computer does startup and seems to function OK however but this is total weirdness. I downloaded and reinstalled the 10.4.8 combo PPC update. I booted from my backup drive and it still does this. While booted from backup I ran repairs on permissions and disk repairs and then I ran DiskWarrior. Still flakey. Last week the power suppluy and logic board were replaced as part of the iMac G5 repair extension program from Apple but this behavior started immediateely after the latest Security update was installed as recommended by the software updates application. Any insight is appreciated. Thanks for reading this and thanks in advance for any help.
    iMac G5 1.8Ghz PowerPC G5   Mac OS X (10.4.8)  

    I zapped the PRAM and all is well now.... Weird! Thanks to all!
    One of the settings in the PRAM can cause the Mac to act like a specific keyboard shortcut was pressed at startup; in your case, it was the verbose mode shortcut, which is Command+V. Some utility software packages can toggle this setting, and it can be changed from the Terminal.

  • Is there a way to set the iPhone to have a black screen with white text?

    I found the "Invert Colors" option under Settings > General > Accessibility, and like it a lot. It provides enhanced readability.
    The problem is that it inverts all colors, even for apps. So when I view a web page in Safari, all the colors are inverted for the images.
    And when I view my photos in Photos, these are also inverted as well.
    Is there a way to set up the iPhone to default to a black screen and white letters for the OS, but allow the apps and photos, etc. to
    be viewed in their regular colors. For example, can I run Photos to view my photos on a black background but view the photos in their
    normal coloring?

    I'm afraid that is not possible, maybe this could bee a step in that direction if you use the mentioned Zoom function:
    Invert Colors and Grayscale
    Sometimes, inverting the colors or changing to grayscale on the iPhone screen makes it easier to read.
    Invert the screen colors. Go to Settings > General > Accessibility, then turn on Invert Colors.
    See the screen in grayscale. Go to Settings > General > Accessibility, then turn on Grayscale.
    Turn on both effects to see inverted grayscale. You can also apply these effects to just the contents of the zoom window—see Zoom on page 150.

  • Black screen with white texts before Windows start in Boot Camp

    I just bought my Macbook 13" and installed Windows Vista in Boot Camp. Everything went fine, Windows run seamlessly with the native speed that's said. My only problem is when I start Windows, it goes through a black screen first with a lot of white texts. One is the message "Unrecognized partition table drive 80. Please rebuild using Microsoft Fdisk Tool." Among others, this message repeats a number of times before Windows start. I don't have any problem after that, except that it delay the start up. I have tried to change a lot of settings that is associated with start up, so far nothing work. Can somebody out there help.

    Highlight the phrase and add "Mac" to it, and do a look-up in Google.
    "Unrecognized partition table drive 80. Please rebuild using Microsoft Fdisk Tool."
    That error is listed on other threads and Microsoft, just easier to find and link thru Google than Apple forum search.
    Hopefully that will help. But I would boot from Vista DVD and go through the automatic system repair too.

  • PLEASE HELP!!! Black Screen with white curser at startup...

    at startup after grey screen fan turns on and screen turns black with a white curser in the upper left. Then one line of text shows saying something to do with single user mode failed with a bunch of other text. (sorry I didn't write it down) It then vanishes for a minute with just the white curser remaining and repeats.
    Ran hardware test... everything OK
    I have repaired permissions which took almost an hour of CD.
    I tried repairing disk failed " Invalid Key Length, volume check failed" twice.
    I am currently running os off external backup HD.
    I tried doing a archive and install but said I could not because the my os software(10.4.11) was newer than my original CD (10.4), is that correct?
    I do not know what to do? Please help!!!!

    You will need to reinstall OS X, but you cannot do an Archive and Install until you repair the drive. See the following:
    How to Perform an Archive and Install
    An Archive and Install will NOT erase your hard drive, but you must have sufficient free space for a second OS X installation which could be from 3-9 GBs depending upon the version of OS X and selected installation options. The free space requirement is over and above normal free space requirements which should be at least 6-10 GBs. Read all the linked references carefully before proceeding.
    1. Be sure to use Disk Utility first to repair the disk before performing the Archive and Install.
    Repairing the Hard Drive and Permissions
    Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Installer menu (Utilities menu for Tiger.) 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 quit DU and return to the installer.
    2. Do not proceed with an Archive and Install if DU reports errors it cannot fix. In that case use Disk Warrior and/or TechTool Pro to repair the hard drive. If neither can repair the drive, then you will have to erase the drive and reinstall from scratch.
    3. Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When you reach the screen to select a destination drive click once on the destination drive then click on the Option button. Select the Archive and Install option. You have an option to preserve users and network preferences. Only select this option if you are sure you have no corrupted files in your user accounts. Otherwise leave this option unchecked. Click on the OK button and continue with the OS X Installation.
    4. Upon completion of the Archive and Install you will have a Previous System Folder in the root directory. You should retain the PSF until you are sure you do not need to manually transfer any items from the PSF to your newly installed system.
    5. After moving any items you want to keep from the PSF you should delete it. You can back it up if you prefer, but you must delete it from the hard drive.
    6. You can now download a Combo Updater directly from Apple's download site to update your new system to the desired version as well as install any security or other updates. You can also do this using Software Update.

  • I installed Mountain Lion and now some times when I start my mac it look with a black screen and white text. I'm really worry about it, can somebody help me?

    I installed Mountain Lion in my IMac and now, some times, when I start up my mac it looks with a black screen and white text. I'm really worry about it, can somebody help me?

    Don't worry, this is probably just Verbose Mode. It's perfectly harmless.  If you're not specifically invoking it, than it's probably down to an unwanted setting in NVRAM.  See this article on resetting NVRAM if it continues to bother you.

  • Black screen with white writing on boot - then nothing...

    Ok, this is a long story, but here's the abridged version;
    I have a mac mini - the old PPC version. It has just come back from being repaired - replacement logic board. However, repaired it is not. Every time i try to start it up, I get a brief white screen with grey apple logo as normal, and then a black screen with white writing on. The writing is exactly the same text as you can see in the console system log. It gets about a page-full through this, and then goes completely black. No video at all.
    However, the machine is still working in there - I know this because I'm typing on it now via VNC. It is perfectly happy and all. It just does this weirdness start up and then no video.
    My question is twofold:
    1. The company that repaired it claims that it booted fine before they gave it back to me; however, it hasn't since I've had it back. Could the boot behaviour be some kind of diagnostic thing they left on my machine, or a mode they left it in. If so, how do I get rid of it?
    2. Failing this, does it sound like my vidoe card packed up maybe?
    Thoughts, solutions, etc., most welcome!

    Have you
    tried to simply do a clean install of Mac OS X and
    your other software? I normally find that this fixes
    90%+ of all unexplained software related issues.
    I could, but (a) I'm not convinced it's not related to the replacement logic board and thus a hardware issue, and (b) I can't see to do a clean install because it has no video signal

  • I don't know what's wrong with my 3GS. It only shows the black screen with white apple. Turning it on then off doesn't help.

    I don't know what's wrong with my 3GS. It only shows the black screen with white apple. Home button and turning the phone off then on doesn't seem to do anything.

    Thanks Lucas,
    I've tried doing that with no results. Same screen keeps showing. Maybe it'd be more helpful if I told you a bit more info.  My phone was randomly playing music, and the voice control would also suddenly start without me touching the phone.  Then I let the battery die and started to recharge when on the screen it indicated to plug into my computer/iTunes, I tried to restore but was getting an error message (can't remember what it said now). Battery died and now my current issue of the black screen with white apple.  I'd love to be able to restore my phone but now its not showing as a device on my iTunes. HELP! Any other suggestions?

  • Black screen with white apple logo won't go away! Help please.

    Last night I turned theipod completeley off and restarted it. The black screen with the white apple logo came on and hasn't went of since.
    I've tried everything I could find in the forums and on the support page.
    iTunes will not recognize my ipod which has continously tried to start up again every 5 minutes.
    I don't know what more to do, ANY help would be greatly appreciated.
    Thanks
    Dana

    I did try that. When I do that the red slider bar to turn the ipod off doesn't come up.
    Its still trying to reset itself but won't go any farther than the black screen with white apple.
    Thanks

  • After installing Yosemite my fax is sending black pages with white text

    I used to send faxes with my Panasonic KX-MB2020 using Prewiew program. With Mavericks faxes were good. After installing Yosemite, my recepients started to tell that they get "negatives" - black pages with white text. Fax machine is ok - if I print a documet and then send it to the same recepient without my notebook, it goes well.
    Please check this bug.

    Furthermore, before now, my Panasonic easily scanned documents directly, with pressing "Scan" button on the machine. Now this operation is impossible - I have to launch Printer properties on my Mac, and from this window I have to start scanning.

  • Itunes 7.0.1.8 / xp --- momentary black screen w/white lines at startup

    I upgraded to itunes 7.0.1.8 about a week ago. It's been fine, except now when I start up itunes a black screen with white lines flashes momentarily, then everything reverts back to normal. I'm pretty sure it just started happening in the last couple days. Also, I just noticed that it only seems to happen when itunes starts up maximized. Otherwise, it's fine. The only thing out of the ordinary that I've done recently is to run an old DOS game that I never ran before. I guess I'm concerned that maybe the game may have done something to cause this. Anyone else out there getting the black screen with white lines at start up?
    Thanks.

    UPDATE/EDIT FROM PREVIOUS POST:
    Ok. The new 7.0.18 does repair the volume slider audio issue. HOWEVER, Simply installing the new update (at least for me) did **NOT** fix the problem. After posting my previous post, I tried to remove Quicktime and iTunes completely and try reinstalling.
    It turns out that when I uninstalled Quicktime from Add/Remove Programs, it didn't remove all the Quicktime files and it was not reinstalling Quicktime afterwards!!
    I only noticed when I downloaded the standalone version of Quicktime and tried running it and it said a "newer version" was on my computer, though it did not show up on my Add/Remove Programs file listing.
    So I looked in the usual places and found that I had a Quicktime folder remaining in the Program Files folder and one in the C:\Windows\system32 folder. I also had to manually remove the following files from the C:\Windows\system32 folder:
    Quicktime.qts, QuickTimeMusicalInstruments.qtx, the Quicktime.Resources folder, QuicktimeVR.qtx and the QuickTimeVR.Resources folder.
    The main problem is that iTunes didn't let me know there was an issue with the QuickTime installation. It just wouldn't run iTunes. There should have been a notification.
    Anyway, after all this, I reinstalled iTunes fresh and checked the volume slider and LO' And Behold! The volume slider issue was repaired.
    However, there is a LOT of skipping occurring that never happened before. Not sure what's up with that. CPU usage stays low and then I get a few skips per minute...UNACCEPTABLE!!! That didn't happen before and that issue will still need to be fixed. Until then, back to WinAmp. Thx a LOT Apple...you *#^@ing hosers!
