Screen flash & restart from boot off another disk

I tried to boot off another disk by pressing option/alt at startup but when I select the disk I want, my screen flashes and my mac restarts. I tried using both rEFIt and rEFInd, but none of them appear on startup. Does any of this have anything to do with the fact that I changed some startup flags so that it always boots into verbose mode? (the flag is -v)

Using Snow Leopard forum is probably your best bet.
I don't care if someone has 20+ yrs, I still like having a good troubleshooting book/manual handy.
Mac: can't get by without bootable backups, even if you use TimeMachine, clone your system. Save you all this fuss and work.
Then invest in high quality disk repair and maintenance program.

Make sure all your software is current, don't install anything you are unsure of or can do without.
Run Apple Hardware Test off your OEM DVD specific to the Mac.
Now, have you Googled for this?
have you looked at reports about 500GB drives used in some Macs that had issues and were offered firmware update for the drive?
Considered just using another drive connected to iMac?

Black Screen - Get Chime - Can Boot off HDD using another Mac - iMac 24in.

Hope someone can help me here, as I'm at my wits end.
I've got two issues, one with my MacBook Pro 17in, 4GB RAM, 160GB 7200rpm (2008) and another with my iMac 24in. 4GB RAM, 500GB 7200rpm (2009).
Firstly the MBP, left work on Thursday last week, got home, powered up the MBP and got a black screen!!! Tried resetting PRAM, SMC, booting in safe mode, removing and re-installing RAM, removing battery and mains power and leaving off overnight etc etc, yet nothing happens. Benn all over the forums and have not found any solution to get my beloved MBP working on it's own. I can boot off the HDD using another MBP 15in, re-install Snow Leopard and as far as I can tell the HDD is fine, as I have run disk utility and it tells me the HDD is OK.
I can't figure this out and it's doing my head in, as I use this laptop for business use and just can't afford to go out and buy another Mac. I should point out that this MBP never had any issues when running on Leopard, but ever since I upgraded to Snow Leopard, I have had nothing, but trouble. I did a clean install, in fact I have done it at least twice, even erasing the HDD securely, both at 7pass and 35pass, yet I have had permissions issues regularly and on the odd occasion, I have also had the problem of the HDD not being recognised.
The iMac is nearly the same, but the screen is working, although the iMac doesn't see the HDD no matter what way I do, again, reset PRAM, SMC, safe boot etc etc. In truth the iMac has been a lot more unreliable, but with the screen working, if I can get any solutions here, then I'll be working to work on that without the need or hassle of working via another.
I think that the MBP is only just still under warranty, but the iMac definitely is, but I need at least one working for business use, so really only want to let Apple have one at a time to look at/repair etc.
Ideally, as the HDD is working in the MBP, if I could get a solution to the black screen issue, then I could do without the iMac for whatever time it takes, so if there is anyone out there that can help, I'd be so grateful.
One last thing, when I bought the iMac 24in., I also bought an iMac 20in., but I never upgraded the 20in. to Snow Leopard and to this day, it has worked flawlessly, without a single issue ever.
Perhaps, I'm getting paranoid here, but there seems to me to be a link between the ongoing and regularly occurring problems with both Macs ant the upgrade to Snow Leopard. Why also, or is it just pure unadulterated coincidence that both the MBP and the iMac 24in have failed at pretty much the same time??!!!!
I'm going mental here, so I hope someone out there has a better fix, then me overdosing on Prozac!!
PS
I'm not a mac expert, not good with a soldering iron either, but I'm capable of following good instructions.

Mac Pro 1.1 won't restart from boot HD or install DVD

I have a MacPro 1.1 quad which won't finish the restart sequence from Boot HD or the Install DVD. I also can't get the DVD to boot to anything but hardware test (D key), which I ran and passed. After reading lots of posts about similar problems, I was pretty sure that it is my ATI Radeon 1900 card gone bad killing the restart right after the Grey apple screen. Then, while trying everything I could think of and finally getting the OPTION key restart to get the Startup Manager, I noticed my old boot camp partition (VISTA) that I had played around with, but never used much. After several failed attempts to get the install DVD to boot, I tried the boot camp partition and to my amazement, after a pause, windows started up. (That's actually how I'm writing this now.)
I ran some tests on the graphics card from windows and it appears to be running fine, albeit a little hot. So now the question: Can the graphics card still be the culprit when it performs ok on the Windows side?
Windows also says that the OSX boot partition of the same drive that boot camp is on can't be read (using MacDrive). But a Seagate HDD diag tool checked the drive and found no errors. I guess that could be part of my problem, but then why wouldn't it boot from the install DVD or in safe mode. I even tried putting the install DVD in my macbook and booting from there in Target mode, with no luck. Also, my install DVD is the original Leopard that came with the machine, but I had upgraded to 10.6.8 later. Would that cause the DVD not to work as a boot disc? I just want to get to the Disk Utility so I can reinstall.
Any knowledge or help would be so appreciated!
Thanks

I have a Mac Pro 1.1 and recently starting having issues. I was running out of drive space for my Vista drive I use Bootcamp. I decided to reinstall Vista on a bigger drive. I went through the normal procedure and had a **** of time installing Vista until I removed the main Lion SSD. Lion has Windows 7 drivers only. So I wanted to reinstall Snow Leopard on a blank drive and get those drivers.
Mac Pro will not read or mount the SL installation DVD. It mounted once and could barely read anything but at a slow rate. I cleaned the disk, but after that despite holding down not the C and D keys at boot up and using Option at boot up the SL kept getting spitted out. Tonight I took it apart and cleaned it with compressed air and vacuum cleaner. I popped the DVD again and it spit it out. I put a DVD movie and it mounted fine. I'm ripping it as we speak. I've done this before just want to see why it won't read SL.
Considered buying an external DVD write for $39 to see if I can get around this issue. Will post back on results. Otherwise this 2007 Mac Pro has been rock solid since then.

IMac G4 won't boot off startup disk

Looking at a G4 20" flat panel for a friend. He blew away some unknown file and hosed the computer. It will not start in safe mode. Get a Darwin kernel panic screen on normal start-up. Will not boot in safe mode. Will not boot off start-up disk (C) - get an interminal grey apple screen that does not proceed. It will boot off of the disk for hardware test (Option), but cannot launch off startup disk icon - get one of those Verboten circles with a line thru it. Hardware test returns two errors loading default text (1) and control (2) fonts and returns an invalid memory access at %SRRO 00000000.00000000 %SRR1 10000000.00083030.
G$ Mac OS X (10.4) unknown version of Tiger

Oops - G5, not G4. And what this young man did was delete his system library. Any suggestions about how to get him up again would be greatly appreciated.

Screen flashes and no boot when DVD is inserted!

I have a new (2 months old) iMac. My wife put in a SIMS3 DVD and weird things started happening after that - the screen would flash, and then eventually go black. I took it to the Apple Store; they found a bad hard drive and replaced it, unfortunately ignoring completely the things I told them about the display going wonky. They gave it back to me and when I brought it home it seemed fine. I then put in a 10.6.3 Install DVD (for the purpose of restoring my whole system off a Time Machine backup) and again - it won't boot (whether or not I'm holding C to boot off of it) and the screen is going wild - flashing on and off. I managed to pop the DVD out (holding down Eject key during boot) and then it booted fine. So: what does it mean that the thing won't boot when a DVD is in the drive? Are there heating problems of some sort perhaps? Why would both the hard drive and the video/DVD drive be bad? Am I missing something? Ideas welcome! thanks in advance,
Mike

Duh!!!!
Thanks Dave. I was converting some of my DVDs to .m4v files for iTunes/AppleTV and set it to Ignore. Changed it back to Open DVD Player and all is as it should be.
Thanks again,

Preventing people from booting off CDs etc.

Is there any way to prevent someone who has physical access to an Intel iMac from booting from an external firewire drive or a CD (by pressing "T" or "C" during boot-up)?
regards,
Peter

Although I admit that this is certainly one of the more confusing KB articles, I don't think it meant to imply that you would be SOL if the OS got hosed. It would have been nice if they wrote a separate article for the Intel Macs.
For the Intel Macs there is software to change the password that is accessed from the installer DVD.

New iMac is stuck on grey apple screen after restart from Migration Assistant

New iMac is stuck on grey apple screen after startup. It is a 3.4GHz Quad-core Intel Core i5 running OS 10.9.4. The problem occurred after a migration from my older 2009 iMac which is running Snow Leopard 10.6.6. When the restart occurred from Migration Assistant, the new computer will not boot up to the login screen. Disk utility did not solve problem. Followed instructions for a soft reinstall of Mavericks but that also did not solve problem. Any suggestions?

Take each of these steps that you haven't already tried. Stop when the problem is resolved.
Step 1
The first step in dealing with a startup failure is to secure the data. If you want to preserve the contents of the startup drive, and you don't already have at least one current backup, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data that has changed since the last backup, you can skip this step.
There are several ways to back up a Mac that is unable to start. You need an external hard drive to hold the backup data.
a. Start up from the Recovery partition, or from a local Time Machine backup volume (option key at startup.) When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in this support article, under “Instructions for backing up to an external hard disk via Disk Utility.” The article refers to starting up from a DVD, but the procedure in Recovery mode is the same. You don't need a DVD if you're running OS X 10.7 or later.
b. If Step 1a fails because of disk errors, and no other Mac is available, then you may be able to salvage some of your files by copying them in the Finder. If you already have an external drive with OS X installed, start up from it. Otherwise, if you have Internet access, follow the instructions on this page to prepare the external drive and install OS X on it. You'll use the Recovery installer, rather than downloading it from the App Store.
c. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, start the non-working Mac in target disk mode. Use the working Mac to copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
d. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.
Step 2
If the startup process stops at a blank gray screen with no Apple logo or spinning "daisy wheel," then the startup volume may be full. If you had previously seen warnings of low disk space, this is almost certainly the case. You might be able to start up in safe mode even though you can't start up normally. Otherwise, start up from an external drive, or else use the technique in Step 1b, 1c, or 1d to mount the internal drive and delete some files. According to Apple documentation, you need at least 9 GB of available space on the startup volume (as shown in the Finder Info window) for normal operation.
Step 3
Sometimes a startup failure can be resolved by resetting the NVRAM.
Step 4
If you use a wireless keyboard, trackpad, or mouse, replace or recharge the batteries. The battery level shown in the Bluetooth menu item may not be accurate.
Step 5
If there's a built-in optical drive, a disc may be stuck in it. Follow these instructions to eject it.
Step 6
Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to start up, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can start up now, one of the devices you disconnected, or a combination of them, is causing the problem. Finding out which one is a process of elimination.
Step 7
If you've started from an external storage device, make sure that the internal startup volume is selected in the Startup Disk pane of System Preferences.
Start up in safe mode. Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a software RAID, you can’t do this. Post for further instructions.
Safe mode is much slower to start and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
The login screen appears even if you usually log in automatically. You must know the login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
When you start up in safe mode, it's normal to see a dark gray progress bar on a light gray background. If the progress bar gets stuck for more than a few minutes, or if the system shuts down automatically while the progress bar is displayed, the startup volume is corrupt and the drive is probably malfunctioning. In that case, go to Step 11. If you ever have another problem with the drive, replace it immediately.
If you can start and log in in safe mode, empty the Trash, and then open the Finder Info window on the startup volume ("Macintosh HD," unless you gave it a different name.) Check that you have at least 9 GB of available space, as shown in the window. If you don't, copy as many files as necessary to another volume (not another folder on the same volume) and delete the originals. Deletion isn't complete until you empty the Trash again. Do this until the available space is more than 9 GB. Then restart as usual (i.e., not in safe mode.)
If the startup process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
Step 8
Launch Disk Utility in Recovery mode (see Step 1.) Select the startup volume, then run Repair Disk. If any problems are found, repeat until clear. If Disk Utility reports that the volume can't be repaired, the drive has malfunctioned and should be replaced. You might choose to tolerate one such malfunction in the life of the drive. In that case, erase the volume and restore from a backup. If the same thing ever happens again, replace the drive immediately.
This is one of the rare situations in which you should also run Repair Permissions, ignoring the false warnings it may produce. Look for the line "Permissions repair complete" at the end of the output. Then restart as usual.
Step 9
If the startup device is an aftermarket SSD, it may need a firmware update and/or a forced "garbage collection." Instructions for doing this with a Crucial-branded SSD were posted here. Some of those instructions may apply to other brands of SSD, but you should check with the vendor's tech support.
Step 10
Reinstall the OS. If the Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
Step 11
Do as in Step 9, but this time erase the startup volume in Disk Utility before installing. The system should automatically restart into the Setup Assistant. Follow the prompts to transfer the data from a Time Machine or other backup.
Step 12
This step applies only to models that have a logic-board ("PRAM") battery: all Mac Pro's and some others (not current models.) Both desktop and portable Macs used to have such a battery. The logic-board battery, if there is one, is separate from the main battery of a portable. A dead logic-board battery can cause a startup failure. Typically the failure will be preceded by loss of the settings for the startup disk and system clock. See the user manual for replacement instructions. You may have to take the machine to a service provider to have the battery replaced.
Step 13
If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store, or go to another authorized service provider.

Cannot boot. volume disappeared from boot option after Disk Utility (GUI) repair

I have a 13-inch MBP with the latest OS X version.
Problem
Yesterday, I went to the Recovery Mode and performed Repair on my boot volume. I was not having a problem, but I just wanted to verify and repair as a regular maintenance. The Disk Utility said some kind of error (I cannot remember, but something about EFI?), and I cannot start my computer since then (question mark folder icon when I try to boot).
I have tried the following
I tried to recover the drive by going into the Recovery Mode, but when I press Option key for boot options, I just have an empty grey screen have no option(not even the recovery volume). I have also tried to enter into the Single User Mode, but it goes straight back to the question mark folder icon. Just in case, I performed PRAM and SMC reset, but still no dice.
Next, I tried to boot with Command+R pressed, and the computer went into Internet Recovery Mode, which works fine. Then, I went to the Disk Utility, and my SSD is on the list with the volume that has OS X(only volume on the entire disk except recovery volume, etc). I use FileVault2, and I can unlock the volume and mount it without any problem. When I do Verify Disk, it says that the volume appears to be OK. Also, performed fsck using Recovery Mode's Terminal, and it still says that "The volume Macintosh HD appears to be OK," the exact same message that I got from GUI disk utility. I also tried to unlock and set the volume as a start-up disk, but I still get the question mark folder icon.
If you need further details, please let me know! Please save me!

Hello jukim,
Thanks for using Apple Support Communities.
Great troubleshooting done so far. Since you're still booting to the flashing question mark, even after repairing the disk, the next step would be to reinstall OS X.

Bluetooth stops working in OS X after restarting from Boot Camp

I just recently installed XP SP3 as a part of Boot Camp on my iMac, which has worked great. Unfortunately, when I boot back into OS X, my bluetooth icon shows up as "Bluetooth: Not Available." I am able to get the bluetooth back by turning off my iMac, unplug everything, and then start it back after waiting a short period of time. So that's the good news, that I can get my bluetooth back, but this happens every time I use Boot Camp. Again, Boot Camp works just fine, bluetooth and everything. But I lose bluetooth when I go back to OS X.
Has anybody else seen this? Any solution(s) to keep me from losing my bluetooth every time coming out of XP in Boot Camp back to OS X? I would appreciate any help...

On this forum lately: JASimon, Oz, sez: " ... There is a bug with ColorSync profiles and Fast User Switching whereby *you can end up with the Generic RGB profile* instead of the appropriate LCD monitor profile after you switch users. You can read a little about it here along with a number of suggested solutions. This leads to a generally washed out and slightly bluish look to your screen (although I imagine it could be purplish depending on your screen).
It doesn't sound like you are using Fast User Switching, but it might be worth checking the Displays control panel when this problem occurs and have a look under the Color tab to see which monitor profile is being used...."

My iPhone 5s screen flashes blue then boots down or resets identical to 2013 blue screen of death

as stated the phone flashes blue after about 15 mins of use phone dosent even feel hot I've done some searches and came up with the 2013 bug blue screen of death relating to 7.0.3 but my phone is running 7.1.2 any ideas guys really frustrating
cheers simon

Standard troubleshooting steps as outlined in the manual are restart, reset, restore, and restore as new. Start by powering off the device, and if that changes nothing, a reset as outlined below.
Close all open apps by double-tapping the home button, then swiping up and off the screen with the app window (not the smaller icon).
Reset your device: hold down the home button along with the sleep/wake button until the screen goes black and you see the Apple, then let go. (No data loss)

IPod mini screen flashes apple on and off..help!

Yesterday, I tried to turn on my iPod mini and the low battery symbol came up, so I plugged it in. When I did, it wouldn't turn on, but instead, the apple keeps flashing on and off every 10 seconds and it won't quit until about 5 mintues has passed. There is also a clicking noise inside, like it is turning itself off and on and trying to restart. Since yesterday, every time I try to plug it in to recharge it, it does this same thing over and over again.
Someone please help . . the answer isn't on the FAQ either!!
Thanks alot! Leighla

OK. I've gotten my ipod working again. Here is what I did.
I reset my ipod (which didn't do anything)
http://docs.info.apple.com/article.html?artnum=61705
And then I put it into hard drive mode (which worked)
http://docs.info.apple.com/article.html?artnum=93651
From there my computer recognized it and I restored the factory settings thru ipod updater. My ipod software was current, so I didn't have the option of updating. It works now and I've reloaded all my music back on. I hope it stays in good health.
Good luck with your issue.

Error when booting off install disk: "panic: We are hanging here . . ."

My iBook's working fine except it's very slow (3 years old), so I decided to reinstall the OS.
When I try loading off my original OS X installation disk, it boots to an error "panic: We are hanging here . . ."
If I stick the install CD into the iBook while it's on, it reads the CD fine and even offers to reboot off the CD for me. But when I reboot, I get the same panic error.
When I take the CD out, the iBook loads fine again.
So my computer still works, but I can't figure out a way to reinstall. Any ideas?
fyi- I tried Disk Utility on my HD and it passed verification.

Call Apple Support. They may be able to send you a replacement disc at nominal cost (much less than new). I think you'll need your computer's serial number so they can get the correct one.
How does the computer handle other CDs? There's the slight possibility it is the drive and not the CD.
The other thing to do is to try and troubleshoot why your computer is slowing down and at least not to have to immediately worry about getting a new CD. Here's a bunch of reading. However, I wouldn't blindly go running a bunch of utilities but to address things one by one. For example, one major slow down is an over-full hard drive and no utility will help with that.

U510 boots off SATA disk and not SSD?

I just bought a U510 thinking the boot disk and OS paging drive would be the SSD. Instead the SSD has static driver files and an application folder with MacAfee. I checked into the Hybrid storage pool concept in Windows 8 but that only seems to be for mirroring and the mirror is from SSD to SATA. Why would the U510 be set up this way - and is there an easy way to change this so Windows 8 lives on the SSD? I didn't get the Windows 8 install media otherwise would have tried changing this around already.
Thanks,

Thanks. So i looked at my cache stats, i'm not sure what it's supposed to say to verify that I have 24gb of ssd hybrid drive? Look at this screenshot and let me know?
http://imgur.com/EjeW9zs,7mrmucg#0
I also took this screenshot to show that there are 2 seperate drives. I googled both part numbers and one is 24gb ssd and the other is 1tb normal hdd.
http://imgur.com/EjeW9zs,7mrmucg#1
One more thing. It appears the 24gb ssd is meant to hold the backup files. I looked at the hidden files and they are for the backup program built it, and it by defaults tries to save a 24gb backup to the 24gb D: drive. This seems like a huge waste of an ssd to house a backup file?
EDIT, just noticed the d drive is 25gb while the ssd is only 24gb, this shouldn't be possible. i am guessing this is a hybrid ssd with caching, but just listed as 2 seperate drives. can anyone confirm?

How to relocate OS X system files to boot off another internal drive?

Hello, Apple forums!
Currently I have a 120 GB SSD installed where the optical drive was in my MacBook, and Mavericks resides on that. I have a second, larger, internal disc I use to house projects, and audio samples (for music production). Recently, I learned that running the OS off an SSD may actually reduce its lifetime, with so much activity on it. I'm wondering about moving the OS to reside on the HDD (there's plenty of room) and using the SSD just for loading frequently-used samples (which would actually be a big time-saver.)
My question is, is it as simple as a copy-paste of all files on the SSD to the HDD, then rebooting holding Option and selecting the HDD? Please inform if there's any problems there. Thanks all.

I don't know who told you running OS X on an SSD would reduce its life. Of course with an SSD a lot of file erasures and frequent read/writes will in time wear out the SSD, but by the time that happened you will no longer be using SSDs.
Furthermore, you cannot simply make drag and drop copies of system files. If you wish to install a system on another drive either you clone and existing drive or you make a completely new OS installation.

BDC screen fields differ from one to another

Hi,
I want to do a recording for tcode KE21. When we run KE21 it has nearly 21 fields on the first screen. But when i do the recording for KE21 using SHDB, the number of fields are just 12 on the first screen. So after the recording, I am getting the error saying that field mismatch or similar to that. I dont want to use KE21N. There is no 'POSITION' button like what we find in VA01. How to solve this?
Thanks

Vijay,
There may be a difference in the screens that you see when you execute the transaction normally and via SHDB for recording. But from a functionality aspect, the SHDB also should cover all the options that you are looking for. This is primarily because the BDC runs in the background and might differ in the way it runs in the foreground.
Regards,
Ravi
