Bootcamp target disk weird screen saver on restart?

I want to make windows my default operating system so I open bootcamp highlight windows & click target disk mode. However when it restarts I get this weird screen saver it looks like computer power & fan symbol side by side moving one point to another extractly like a screen saver.

Hmmmm... that's weird, you might try selecting your Startup Disk in the System Preferences / Startup Disk and see if that stop's it. Just click on your start up drive once, just enough to highlight it and it should "stick".
Did you completely remove Window's AND the partition or just remove Windows? If you only deleted Windows just have Boot Camp Assistant or Disk Utility "Restore" the partition to one again.
Other things you might try, Try re-setting the PRAM, or try booting from the 10.6 MacOS installer disk and "Repair Disk" and see if either one works.
You might even try an external keyboard and see if maybe the "T" key on the built in one may have a defect. Yes it has happend.

HI and Welcome to Apple Discussions...
Boot from your install disc and run Disk Utility in case the startup disk needs repairs.
Insert your install disk and Restart, holding down the "C" key until grey Apple appears.
Go to Installer menu and launch Disk Utility.
Select your HDD (manufacturer ID) in the left panel.
Select First Aid in the Main panel.
(Check S.M.A.R.T Status of HDD at the bottom of right panel. It should say: Verified)
Click Repair Disk on the bottom right.
If DU reports disk does not need repairs quit DU and restart.
If DU reports errors Repair again and again until DU reports disk is repaired.
When you are finished with DU, from the Menu Bar, select Utilities/Startup Manager.
Select your start up disk and click Restart
While you have the Disk Utility window open, look at the bottom of the window. Where you see Capacity and Available. Make sure there is always 10% to 15% free disk space
If you cannot boot from your install disc, try booting in Safe Mode You can run Disk Utility from there.

Using Target Disk mode to reinstall OS-X

I have a PPC G5 Dual 2.0gHz which failed the other day. All the fans were running full and a red LED showing on the logic board (it's just a warning I think). Since then the machine cannot be started up. It will begin the startup process normally but will hang on the Apple logo screen (no spinning gear wheel).
The same thing happens when attempting to start up from the install disks and also when started in safe mode or with Option pressed down at startup.
The logical assumption (given the original failure) is a hardware problem but I'm not entirely certain that's the case and cannot get it to a technician right now. I can run Apple Hardware Test and it passes that. I can also mount the G5's drive in Target Disk mode using a PowerBook G4 as a host so the drive itself appears to be okay. All the data is there and can be transferred.
Is it possible that this is software not a hardware issue? The normal startup chime is there, the relay clicks at startup and it does begin to access the drive and all the normal noises can be heard. Just stops loading at the Apple logo screen. I'm wondering if some OS files were corrupted in the original crash (which happened overnight so I don't know what caused it) and if there is some way to eliminate the OS as the problem before going to a technician.
As I can mount the drive in target mode, is it possible to use my PB as a host and reinstall the G5 OS-X that way? They're different machines so I don't know if that would work or the PB would reject the installation. Alternatively, if it could be just corrupted OS system files would it make sense to try to 'guess' the most likely to have been corrupted and manually replace them, again using the PB as a target host?
I'm really stuck without this machine but just can't get it to a workshop for at least a couple of weeks so I'll try anything!

Boy, I love these forums, and I love Macs (most of the time). I was so convinced this was hardware but it seems (fingers crossed) to be fixed. Yay!
You guys were both right in a way. Roam's solution would clearly have been the easiest but because I had tried it before without success I didn't expect it to work. And, trying it again with the G5 install disk, it didn't. Same problem as before. But Graham's reminder of using the original multi-machine Tiger disks in target mode made me wonder. So before trying Target Disk mode I tried just restarting the machine using the Tiger DVD instead of the G5 disks -- and it booted into the installation dialogue!
I figured I'd need to reinstall 10.4 (and, if it worked, go through the whole update drag to get back to 10.4.10). Before I did that though, on a whim, I tried quitting the installer and selecting the normal G5 system as the startup disk. Restarted and voila -- there it was, all back to normal, everything sweet and no data lost!
I didn't even need to repair the disk. Disk verify shows no problems. Even repairing permissions was just a couple of minor changes. I'm amazed. And delighted.
I might be jumping the gun and there might still be a hardware problem that will repeat the original failure and I'll find all the fans going full blast and nothing working again tomorrow but, if Murphy is having time off, for the moment I'm back in business.
I would love to figure out what caused the problem in the first place. I suspect a big power surge overnight did it but I have no idea exactly what it did to cause these symptoms.
My grateful thanks guys.

Pismo with Tiger won't go into target disk mode

I recently upgraded my Pismo to Tiger and can't seem to boot into firewire target disk mode. The computer restarts and gives me a terminal screen that reads: "can't OPEN DISK" and then goes on to say "Welcome to Open Firmware. To continue booting, type "mac-boot"..."
I tried zapping the pram, but that did nothing. Does anybody have any suggestions?

MacUser,
When booted in 10.4.8, select Target Disk Mode in the System Preferences > Startup Disk and see what happens.
If no success, try resetting Open Firmware (from Apple docs):
Boot into Open Firmware by holding down the 'Command-Option-O-F' keys from a cold start while the chime is being played. You will see a command-line screen...enter these commands:
1. At the Open Firmware prompt, type: reset-nvram
2. Press Return.
3. At the Open Firmware prompt, type: reset-all
4. Press Return.
Example:
0 > reset-nvram
Press Return
0 > reset-all
Press Return
The reset-all command should cause the computer to restart. If this occurs, you have successfully reset the Open Firmware settings.

Apps show in mission control but won't open after it has gone to screen saver

I have three desk tops open on Mission Control, plus dash board. If I leave the computer and come back later and go to the desk top there is nothing there. When I click on the app it shows it is open, but just flashes and then it is gone. I have set the app, under options, to be on a particular desktop. I have to close out the app and reopen it to see it.

Disable screen saver. Restart.

Target disk mode only shows bootcamp partition

My mid 2006 MBP doesn't boot anymore, I am getting the gray screen with the rotating wheel.
When trying to boot in target disk mode and connect it to my iMac only the bootcamp partition is mounting, but not the Macintosh HD, I could like to make a backup before I run to the Genius Bar.
Any ideas on how to get to the real HD?

I can't boot from snow leopard DVD either. When I try, the DVD just ejects. I was able to boot once in safe mode, repaired disk permissions there. Since then it's not booting anymore. Sometimes I get a gray progress bar, sometimes just spinning wheel. Can't even boot from external disk.
The only thing that works is booting into Windows Safe Mode. But screen looks fuzzy, with small horizontal lines all over the screen.
Before my MBP froze there were 8 horizontal lines around the mouse cursor under OSX.
I just want to try to get to my Mac partition to backup the drive before I go to the Genius Bar.

G4 PPC won't Sleep, Restart, or run Screen Saver

Hi all,
My 7 year old 1.25 GHz G4 PPC, until recently, has run with little to almost no problems (at least nothing I couldn't solve on my own).
Now, this past week all of a sudden I can't get the computer to go to sleep, either through Energy Saver settings or manually. It just doesn't respond and nothing happens. I read through some other similar questions that have been posted in the past and tried a few of the offered solutions. I've run disk utility, and tried disconnecting all USB peripherals, still non-responsive.
Likewise, I can't get my screen saver to run either through Energy Saver settings or through my Hot Corners (all other hot corner settings seem to work fine). It will only launch through System Prefs > Desktop & Screen Saver > Test.
The last problem I have noticed so far is that I can't perform a restart, when I do the process starts, but almost immediately goes to a grey screen with the little spinning circle (the one that looks like a clock face) and stays that way. I've let this screen run for as long as about a half hour to see if something would happen, and nothing did. In the end I have to force a power down by holding down the power button.
Again, as recommended elsewhere, I have repaired disk permissions and verified the disk, with still no change. I have disconnected all usb peripherals (3 external HD's, iPod, powered usb hub, despite the fact it's worked fine for the past 6 months with all these connections [6 months ago my firewire 400 ports stopped working, haven't replaced them yet]). I have not installed any new software recently, and my last software update before this started happening was iTunes 8.2.1 a couple of days before I first noticed the problem.
Any ideas?

Hi japamac,
Thanks for the tips. (I had to create a new account here).
Tried all your advice and nothing worked. I ended up getting fed up and tried reinstalling OSX and that didn't work either. After that I zeroed my drive (twice) and started from scratch. That's why I've been late in responding, it takes forever to backup your system when all you have to work with are usb ports at 12kb/s.
Anyway, upon completion of zeroing my HD I reinstalled OSX 10.3 and checked all my settings, no issues were apparent, I could put the computer to sleep, run my screensaver, and all hot corners worked as well, all with no apparent problems. After that I downloaded and installed all updates for OSX 10.3, and still everything worked fine. So next I reinstalled OSX 10.4 off my disk, and once again, everything worked fine. So I started with my software updates (just the basics) one at a time retesting after each one, Java updates: everything worked, iPod phone support: everything worked, DVD Player update: everything worked, then I updated the 10.4 update bundle to 10.4.11 and all the problems returned. So I started over one more time, this time updating OSX first, and still, as soon as 10.4 is updated to 10.4.11 the problems return.
So what could be happening with my computer that an operating system update (one I've had and run since it first came out, with no previous problems), is all of a sudden causing some sort of conflict or is just buggered in general, even after I have erased and zeroed my HD twice (presumably deleting any other file/program that could have been causing the conflict in the first place).
And because I erased my HD, all my login settings for this forum were gone and I couldn't remember my login info so I had to create a new account.
Thanks again,
Chris

Target Disk with firewire only recognizes bootcamp!?

Hi there, my MBP will not boot anymore.. it just stays at the apple logo.. I only want to rescue some files I really really need(the rest I have on time machine) but when I try to Target Disk my MBP to another MBP it only recognizes the partition which contains Windows XP..
Does anyone have only a slightest idea of what I can do?

Usually means the OS X volume is inaccessible. You might try reinstalling OS X if possible:
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.
Failing that see the following:
Basics of File Recovery
Files in Trash
If you simply put files in the Trash you can restore them by opening the Trash (left-click on the Trash icon) and drag the files from the Trash to your Desktop or other desired location. OS X also provides a short-cut to undo the last item moved to the Trash -press COMMAND-Z.
If you empty the Trash the files are gone. If a program does an immediate delete rather than moving files to the Trash, then the files are gone. Recovery is possible but you must not allow any additional writes to the hard drive - shut it down. When files are deleted only the directory entries, not the files themselves, is modified. The space occupied by the files has been returned to the system as available for storage, but the files are still on the drive. Writing to the drive will then eventually overwrite the space once occupied by the deleted files in which case the files are lost permanently. Also if you save a file over an existing file of the same name, then the old file is overwritten and cannot be recovered.
General File Recovery
If you stop using the drive it's possible to recover deleted files that have not been overwritten with recovery software such as Data Rescue II, File Salvage or TechTool Pro. Each of the preceding come on bootable CDs to enable usage without risk of writing more data to the hard drive.
The longer the hard drive remains in use and data are written to it, the greater the risk your deleted files will be overwritten.
Also visit The XLab FAQs and read the FAQ on Data Recovery.

Grey screen on Target Disk mode boot up

I have a home iMac, Late 2012, OSX 10.9.1, 32GB, and a corp MBP, Late 2011, 8GB. I would really like to use Target Disk Mode to boot the MBP on the faster iMac - it worked once or twice and was fabulous, but that was when both were on Lion.
Now after upgrading both to Mavericks, Target Disk mode bootup isn't working anymore. I get to the Login Screen on the MBP bootup, but after logging in i just get a grey screen. Nothing else.
Pretty sure i'm doing everything right. Connect both, boot target with cmd-T, boot host with "alt", select startup disk, login ..... then nothing.
Fix is probably simple - any help would be great.

Ok this is a guess.
Are you trying to use the system files etc on the iMac to run the MBP?
If so I am surprised it worked in Mountain Lion, the Video cards probably have different drivers and that could be why you cannot login but the login screen with standard resolution works.
You could try and match the resolution on the iMac with one that suits both machines but running it that way is not something I would do.
Perhaps I understand your question incorectly, if so apologies and disregard my post.

Screen Saver not working & Phone Restarting unexpe...

Hi,
Never expected this problem on my Nokia 701 after updating to nokia belle fp1. My phone restarts unexpectedly even though i m not using it and also while using some applications. Also my screen saver does not work whatever i do the screen saver just doesnt come i dont know whats the problem as i also tried to reinstall the belle fp1 on my phone through nokia suite and still the issue remained the same.
. the issue looks small but its very frustrating that the battery goes down because of no screen saver and every time reboot without any reason.
I request nokia to go through this message and look into this issue and release a bug fix for this issue.
Moderators notes: Inaccurate information removed.

Don't call me crazy but...last night I activated a hot corner to put display to sleep, no screen saver, nothing, just off. This morning, a minute ago, I checked the display and it's fine again. No shadows, as if the "memory or imprint" of the images were cooled off and erased. The display is clear again!
Not crazy at all, it's what I would expect. LCD screens can experience a temporary image persistence, if an image remains static for a very long time, but it is not a permanent effect. Letting the screen rest can help eliminate the persistent image, and if that doesn't, you can get rid of it by displaying a white full-screen image for a while with the brightness turned down to low.
For more information, see:
http://support.apple.com/kb/HT2807
As to why your screensaver quit working, I don't know.

Cannot clear screen saver picture after sleep. A restart is required to resume work.

A three year old iMac owned by a friend freezes after sleep. It seems the screen saver picture will not clear. A force quit or finder restart does not work. Only way to resume work is to restart the computer.

Turned out a bad USB device was preventing sleep. Once I removed it the display went to sleep like a baby.

Why does screen saver prompt for secure disk image password?

Okay, seems like an odd problem, but here it goes.
I go into System Preferences->Dektop & Screen Saver. As the program "loads" availabe image sources and such I get a pop-up requesting a password to my secure disk image.
Yes, I have a secure disk image in my home directory.
Yes, the secure disk image is currently "locked" (Not mounted in finder).
I click cancel (a few times, probably 2 maybe 3 times) and things continue along fine.
I select a photo source that I want for a screen save and exit peferences.
I then go an start the screen saver (I'm using Hot-Corners).
I get the message "Looking for pictures....." for , well...basically forever...
Sure enough I touch the mouse to leave my screen saver and there is the pop-up again. Asking for me to unlock my secure
disk image.
I thought this might be related to Spotlight. I tried reading several threads and have gone as far as taking my entire hard-drive/volume
and putting it into the "Privacy" tab under spotlight.
Anybody have any idea on what is going on and how I might get it so the "Desktop & Screen Saver" stop prompting me to unlock my
secure disk image? (WITHOUT having to make sure the disk image is unlocked before I sleep my screen or open the screen saver utlity)
As always, I am only speculating that this is Spotlight related so that could be a red-herring....
thanks in advance.
OSX:10.7.3
imac/3.1G/Intel

Update: i made some progress on this issue. I found that in the ~/picture/iPhot Library/Database/ directory
there is a file called Library.apdb. This file has an entry for the secure disk image i have/had. I moved the file
to Libraryapdb.bkup and sure enough, my picture problem went away. The screen aaver panel no longer prompts
me to unlock my secure disk image.
So now the next chapter of my problem;when i open up iPhoto it wants to rebuild my photo library(which makes
sense and is what i want to haopen) so i allow it. After about 25 mins it has rebuilt the iPhoto library, but there is
one problem. The secure diskimage reference is back in the Library.apdb file that has been recreated!
So now i need to figure outnhow to get iPhoto to remove anynreference to a phot library i once had on the secure
disk image but have long since removed.
I first created an iPhoto library on my secure disk image by holding the option key and invoking iPhoto.
I removed that library awhile ago....
So how do i make iPhoto remove a no longer used iPhoto library?

Target disk mode for edit and save?

I have about 40 GB worth of photoshop files on a white Macbook 2009 running Lion and I need to delete layer 1 from each file. Is it safe to start the Macbook in target disk mode, mount it on my MDD G4 (running 10.4.11) and then run a PhotoShop batch on the G4 which deletes layer 1 and saves to original location? I don't have room to move the files to the G4 and my older version of Photoshop won't run on the Macbook.

Sure, "in theory" there should be no problems at all!
However, risking the ONLY copy of your data doing a non-reversable change is just a generic "bad idea"!
Always working on copies is a general good practice.
Always!

IBook screen flickers in Target Disk Mode or in Open Firmware

When booting in Target Disk or Open Firmware the screen seems to shift to one side showing a duplicate of the displayed image. In addidtion to this on the right hand side of the screen roughly about 1" wide the image is completely distorted. I'm not sure but I think the problem only occurs when the Power Adapter is plugged in (Still testing).
Update: The problem occurs with or without the power supply connected. In addition to the above the screen distortion can sometimes be intermittent and does not always distort in the same position as described above.

When you can't boot from any method it usually signals that one of 2 things (maybe both) have failed:
Motherboard
Hard drive - Some hard drive failures lock up the ATA controller so badly that the Mac can't boot from any device.

Hot corners enabling screen saver/ ss not working; restart they're working

Hi, for no discernable reason, my hot corners which are set to start secreen saver were not working; neither it seemed was my screen saver turning on. My computer seemed simply to be going to sleep from the screen image of the desktop without benefit of having gone through the screen saver cycle first. I ran disk utility and verified permissions. Then I did the old pc trick of rebooting the computer. That seemed to have done it. My hot corners are working the way they were set up to function. Por Que? Why is my PB G4 behaving like a PC?
Thanks.

Hi, Nagafugi
Had the same problem and here's what worked for me:
Navigate to System Preferences/Desktop & Screen Saver/ and click the Hot Corners button.
I generally set the bottom left corner to Start Screen Saver, with all of the other corners set to minus. I temporarily set the top left corner to Disable Screen Saver, and after moving the mouse pointer into that corner, I was then able to use my bottom left corner again to start my screen saver.
I put the top left corner back to minus.
Simple enough and good luck!
