Ok so i got this laptop in a few days ago here are the problems and the things i have tried. This laptop when it came to me did not have a hard drive, so obviously no OS. Upon installing a hard drive then trying to load Yosemite from a USB stick, I turn mac on, sleep light will blink 5 times then boot, Will come to normal gray screen then apple logo, will then load the OS install, but go straight to a blue screen with vertical lines. Tried different hard drive, tried different RAM sizes and speeds, tried different OS, tried CD instead. Have done numerous PRAM and SMC resets. trying Safe mode gets me a panic cpu 4 caller error then restarts. I have tried using a hard drive that had an OS already installed and will go straight to blue screen after loading. I have tried fsck -fy in single user mode. I do get that disk2s3 is write protected in single user mode, but im pretty sure that its the OS disk. I do not see a second hard drive in single user mode but i believe that because its not partitioned yet. Any ideas community?

Tried doing OS X lion by CD now, and will only get half way through load bar before the apple logo and loading bar disappears and then it will sit at a gray screen.

Blue screen after appemtping a safe boot. HELP!

I attempted a safe boot after receiving a gray screen w/ spining gear. I have since gotten a blue screen. PLEASE HELP!

Hello,
Could be many things, we should start with this...
"Try Disk Utility
1. Insert the Mac OS X Install disc, then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu at the top of the screen. (In Mac OS X 10.4 or later, you must select your language first.)
Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.
3. Click the First Aid tab.
4. Select your Mac OS X volume.
5. Click Repair. Disk Utility checks and repairs the disk."
http://docs.info.apple.com/article.html?artnum=106214
Then try a Safe Boot, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when it completes.
(Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive.)

Blue screen at start up Safe Boot however works...please help

After reading various posts around I can't nail it down...
My powerbook boots to a blue screen which changes 2 hues and then stops.
However, it will boot up in safe boot.
Things I have tried so far (hope I don't forget something):
1) Repair permissions.
2) Boot from Diskwarrior cd and perform repairs.
3) Reset nvram
4) Boot in open-firmware mode and reset pram and all
5) boot in single-user mode and perform that unix command ("fsck -fy" or something like that
6) ran apple hardware diagnostics from original apple cd that came with my powerbook. Here is where it gets interesting. The first time it reported an error with one of my RAM chips. I ran it again and it passed all tests. I ran it a third time and passed again...."hm..." I murmured to myself.
At this point I am suspecting it is a hardware problem but I can't trace it.
Keep in mind that the powerbook boots up fine Safe Boot mode.
Please help!

Unfortunately this problem remains unsolved.
I am able to work in safe mode however, no sound, no extensions, nada...
Too bad as I was eagerly waiting for the Airbook to be my pb replacement which isn't the case.
I a disappointed that Apple gave precedence to form over function for the Air. It will never replace
the tiny footprint of my pb, nor does it offer its options.
I don't care if a laptop is a millimeter thin. It still has the same footprint as a Macbook on a desk.
Apple tell us if this is easily fixable or should be just trash our PBs?
Other users report the same problem on various sites...

Startup issue - blue screen freeze before login - Safe Boot works fine?

I've not seen this before and I can't fix, wonder if anyone has any new suggestions, here is what I've tried so far... (safe boot works fine)
1. Verbose and Single user login
2. removing the startup folder from disk library
3. Zapping PRAM
4. Reset SMC
5. Zeroed disk and reinstalled system
6. Target disk and disk repair (No Problems Found)
7. Permissions repair (No Problems Found
8. Apple Hardware Test (No Problems Found)
9. System DVD Startup - Disk Utility (No Problems Found)
10. Network Startup - Disk Utility (No Problems Found)
In every case unless I hold the shift key down for safe boot, the mac will freeze on a blue screen when the grey screen disappears, and never proceed to login. Thought about replacing the disk but it's a lot of bother on these machines and there doesn't appear to be anything wrong with it??
Any ideas?
Can anyone think of a possible fix not listed above?

Hello chip
The only thing I see missing from your list is, have you disconnected all External HD's, iPods and other storage devices befor Starting up? Sometimes when the iMac has multiple storage devices connected the Startup Manager will get lost.
Also try going to: Startup Manager in System Preferences, select the Macintosh HD and restart the iMac..

21.5 iMac display blue screen after installing Win7 and boot camp

I installed Windows 7 on iMac, it reboot fine.
But after I installed the boot camp 3.0 from Mac OS X 10.6 disc and pressed the restart buttom, the computer restarted and displayed a blue screen before entering the Windows and then reboot again automatically.

Thanks

Can´t view photos in full screen after loading photos to dropbox? what to do?, can´t view photos in full screen after loading photos to dropbox? what to do?

after loading photos to dropbox i can´t view them in full screen in iphoto ... i can only view them small ... when i click on them this sign "!" appears... do you know how to fix this????

If you're loading photos to drop box why do you expect to see them in iPhoto?
The ! turns up when iPhoto loses the connection between the thumbnail in the iPhoto Window and the file it represents.
Remember: we cannot see your machine. There are 9 different versions of iPhoto and they run on 8 different versions of the Operating System. The tricks and tips for dealing with issues vary depending on the version of iPhoto and the version of the OS. So to get help you need to give as much information as you can. Basic things like :
- What version of iPhoto.
- What version of the Operating System.
- Details. As full a description of the problem as you can. For instance: 'iPhoto won't export' is best explained by describing how you are trying to export, and so on.
- History: Is this going on long? Has anything been installed or deleted?
- Are there error messages?
- What steps have you tried already to solve the issue.
- Anything unusual about your set up? Or how you use iPhoto?
Anything else you can think of that might help someone understand the problem you have.

Stuck on blue screen, after os x loads

Unable to get MacBook pro to move past blue screen after os x loading bar completes. Doing safe start gets me past login screen only to freeze on blue screen again. I've tried running applejack, I've tried re-starting holding down shift + ctrl + option and I've tried starting using command + d. All methods end with the same results, frozen blue screen. To make matters worse, the disc drive recently decided to crap out.

It's possible. You should make a good up to date backup before reinstalling the OS.
Do you have a friend with a Mac, and do you have an empty external hard drive? If so, you can mount your Mac's hard drive on your friend's desktop using FireWire target Disk Mode:
http://support.apple.com/kb/HT1661
You can also mount the external hard drive on your friend's Mac. Once that is done, you can use Super Duper or Carbon Copy Cloner to make an exact copy of your Mac's hard drive on the external, which will give you a good up to date backup. It should preserve everything on your hard drive including all the files.
I believe that you can use your friend's optical drive to install the OS on your boot drive, but I don't know in detail exactly how to do this.
Probably someone else on this thread could provide the details.
Good luck!

My Macbook will not boot the operating system. It just goes to a blue screen after the apple logo and the spinning wheel goes off. I took the battery out and held the on/off button for five seconds and reset the PRAM. I have the old mac os disk.

My macbook will not boot. It goes to a blue screen after the logo and wheel goes off. I have taken the battery out and held the on/off button for five seconds and reset the PRAM. I have the the original os disk but have not put it in for fear of losing un backed op data.
Thanks

You won't lose any data unless you erase your hard drive.
Put your install DVD into the optical drive and reboot. As soon as you hear the boot chime, hold down the "c"key on your keyboard (or the Option key until the Install Disk shows up). That will force your MacBook to boot from the install DVD in the optical drive.
When it does start up, you'll see a panel asking you to choose your language. Choose your language and press the Return key on your keyboard once. It will then present you with an Installation window. Completely ignore this window and click on Utilities in the top menu and scroll down to Disk Utility and click it.When it comes up is your Hard Drive in the list on the left?
If it is then click on the Mac OS partition of your hard drive in the left hand list. Then select the First Aid Tab and run Repair Disk. The Repair Disk button won't be available until you've selected the Mac OS partition on your hard drive. If that repairs any problems run it again until the green OK appears and then run Repair Permissions.

Some clarification may help.
You say you cannot boot normally. It shows a gray screen with the Apple logo.
Did you say it will boot successfully in Safe Mode (boot, then hold down the Shift key)?
How did you boot the machine to run Disk Utility? (Which keyboard combinations)?

Satellite P30 - Blue screen after reinstall OS

I just reinstall OS (Windows XP) on my older laptop Toshiba Satellite P30, but after first reboot (required to continue XP configuration) the DOS blue screen appear (System Has Recovered From Serious Error).
The laptop cannot load Windows XP at all. Do you have some idea whats going on ?
Thanks :)

Hi,
This looks like a hardware issue. You should check the HDD and RAM.
http://www.hitachigst.com/hdd/support/download.htm#DFT
With the Drive Fitness Test you can test your HDD. Download the CD image, burn it on a CD and boot from it. Then you can the HDD.
On the same website is a user guide if you want to know more.
http://memtest86.com/
Memtest86 is a diagnostic tool to check the RAM. There you can also download a CD image.
Its easy to use. Run the test 3-4 hours and then you will see if the RAM has some errors.
Good luck!
Bye

Blue Screen after clean reinstall snow leopard

I have a mid 2011 that came with Snow Leopard and disks. I upgraded from there to Lion - then whatever came next and to Mavericks and finally Yosemite, which was a nightmare for me. I did not use disks of any of the rest. So I just decided to take my disks and go back to Snow Leopard. I did this and it asked to go to disk utility and repair both the HD and Permissions. It came out ok, but there was an instance where looking at the list in HD repair, I saw Suid File System Library Core was moved and cannot be repaired. I went ahead and erased the Hard Drive. Then closed out and installed Snow Leopard. I'm not sure I did it right because I had to rename the new start up disk and typed in unnamed 1.
after that I was able to start up to Snow Leopard. It worked fine until I tried to download all the updates. Then it didn't seem to restart, but just went to the sign in screen. So I had to keep shutting down and turning it back on. No updates. One of times I started up, I got the blue screen after the apple and gray screen.
Also on start up the apple comes up without the chime. Last night I got some instructions from a similar situation and tried to use my disk to a clean reinstall all over. It didn't work, still the blue screen. (it does fine in safemode.)
I need help to get this mac running. If someone can help me......

Clean Install of Snow Leopard
Be sure to make a backup first because the following procedure will erase
the drive and everything on it.
     1. Boot the computer using the Snow Leopard Installer Disc or the Disc 1 that came
         with your computer. Insert the disc into the optical drive and restart the computer.
         After the chime press and hold down the "C" key. Release the key when you see
         a small spinning gear appear below the dark gray Apple logo.
     2. After the installer loads select your language and click on the Continue
         button. When the menu bar appears select Disk Utility from the Utilities menu.
         After DU loads select the hard drive entry from the left side list (mfgr.'s ID and drive
         size.) Click on the Partition tab in the DU main window. Set the number of
         partitions to one (1) from the Partitions drop down menu, click on Options button
         and select GUID, click on OK, then set the format type to MacOS Extended
         (Journaled, if supported), then click on the Apply button.
     3. When the formatting has completed quit DU and return to the installer. Proceed
         with the OS X installation and follow the directions included with the installer.
     4. When the installation has completed your computer will Restart into the Setup
         Assistant. After you finish Setup Assistant will complete the installation after which
         you will be running a fresh install of OS X. You can now begin the update process
         by opening Software Update and installing all recommended updates to bring your
         installation current.
Download and install Mac OS X 10.6.8 Update Combo v1.1.

Server 2012 R2 Hyper-V Cluster, VM blue screens after migration between nodes.

I currently have a two node Server 2012 R2 Hyper-v Cluster (fully patched) with a Windows Server 2012 R2 Iscsi target.
The VMs run fine all day long, but when I try to do a live/quick migration the VM blue screens after about 20 minutes. The blue reports back about a “Critical_Structure_Corruption”.
I’m being to think it might be down to CPU, as one system has an E-2640v2 and the other one has an E5-2670v3. Should I be able to migrate between these two systems with these type of CPU?
Tim

Sorry Tim, is that all 50 blue screen if live migrated?
Are they all on the latest integration services? Does a cluster validation complete successfully? Are the hosts patched to the same level?
The fact that if you power them off then migrate them and they boot fine, does point to a processor incompatibility and the memory BIN file is not accepted on the new host.
Bit of a long shot but the only other thing I can think of off the top of my head if the compatibility option is checked, is checking the location of the BIN file when the VM is running to make sure its in the same place as the VHD\VHDX in the
CSV storage where the VM is located and not on the local host somewhere like C:\program data\.... that is stopping it being migrated to the new host when the VM is live migrated.
Kind Regards

Blue screen after upgrades - 3000 J115 7387-A32

I recently upgraded the graphics card and memory on my Lenovo 3000 J115 7387-A32. After the memory upgrade I noticed that when the computer booted it would 1) go to the blue screen, 2) automatically reboot, 3) boot normally to windows vista.
I upgraded the Graphics Card from an onboard Nvidia 6100 to an Nvidia 8500 GT pci expressI completed this upgrade a couple days prior to the memory upgrade and noticed no issues when booting the computer.
I upgraded from 1 gig (2 x 512 mb) of memory to 4 gigs (2 x 2g) ddr2I did notice that the bios system summary notes the memory as 2.5g while the vista - control panel - system notes 4g, but based on the other posts that seems to be a 32-bit OS limitation and should not be causing the blue screen.
After the computer boots normally, it acknowledges that it did not boot properly and offers to find a solution. It notes that the problem is due to the NVIDIA nforce serial ATA driver (which as far as I can tell is not related to either graphics card?) and takes me to the NVIDIA site. I scan my system for both graphics and motherboard, and the results of both scans are that I have the most up to date drivers available.
I did update my bios through this process.
It does eventually boot up and seems to be working fine, but the blue screen shouldn't occur and I would like to prevent it if I can. I would appreciate any help on this issue.

what are you specs cause i also had some bluie screen errors b4 ( didnt upgrade anything at that point)..and btw i am also looking for an upgrade on a graphics card...i found couple but i have no clue how much my lenovo 7387 can handle (in terms of power supply) can you please help me out here...
Thanks
