Getting stuck at boot

I tried to add something into rc.local (esd something), I guess I forgot the & because now it just freezes at that point.
I deleted the safe boot option out of LILO, would that have helped this?

That's a FAQ. The program is, as you correctly gathered, running in foreground. This also means, however, that you can send it a SIGINT with CTRL-C and kill it that way. If SIGINT is captured, try CTRL-D, CTRL-U, CTRL-Z and CTRL-X. One of 'em ought to get you further.

Q10 switches off when power button pushed once and gets stuck in boot up loop

Hi All
All of a sudden my Q10 power button has become sensitive and restarts when pushed once. When it tries to restart it gets stuck in the boot loop - going from red light to BlackBerry logo, back to red light.... If I push the power button a few times it will boot up.
I have tried to reload the most actual 10.3 software but problem still exists.
Any ideas? Oh and its JUST gone out of warranty.....
Is it a power button issue or something more serious?

Sounds like button. I'm assuming that is one way they can fail. I don't know for sure. What I usually read about button problems is the button doesn't work at all.
The issues could with the 10.3.1 upgrade complicates guesswork. How did you reload the OS? If you did a clean install with an autoloader then I would say you did what you could do to rule out software.

P67A-GD65 gets sometimes gets stuck on boot status code 98 until i turn of main

Hi,
I have a issue which seems to be more recurring over time - it simply gets stuck on the first status code screen, it continues to do it until I power down system by mains for 10 secs.
To start with I'd say only once a month but now about once a week.
The usual boot status codes read "98 B4 98 94" and when the problem occurs it just gets stuck on the first 1.

Would love to hear from some others because I don't know what to do about it really with it being quite rare it's hard to test possible causes/fixes.
Thanks.

I don't really know as I have the as shipped BIOS 1.9 on mine and only problem I have is my mouse doesn't work in BIOS and since mice never worked in BIOS before these new MB's it's nothing I'm concerned about. It seems every new BIOS fixes one thing and then another problem crops up for other people so I'm sticking with the no mouse and no other problems BIOS 1.9. The only BIOS's I understand that have had the fewest problems for most people have been 1.9 & 1.C. Mines goes through POST so fast I can't even read anything as it flashes by everything in just a few seconds and goes to loading Windows.
Unplugging the USB devices was just a suggestion for test purposes not a work around for the problem.

Late 2007 Intel iMac getting stuck at boot...sometimes.

I'll go into as much detail here as I can, but feel free to ask questions. This is:
Model Identifier: iMac7,1
Processor Name: Intel Core 2 Duo
Processor Speed: 2.8 GHz
Number Of Processors: 1
Total Number Of Cores: 2
L2 Cache: 4 MB
Memory: 4 GB
Bus Speed: 800 MHz
Boot ROM Version: IM71.007A.B03
SMC Version (system): 1.21f4
I rarely shut this computer off, and for the most part it runs fine, but when I do shut it down or Restart, whether it boots again or not is a gamble. I have backups, so I'm not concerned about losing data, just concerned by the instability. There's no boot camp or strange partitioning. Just a single partition "Macintosh HD" that the system boots from.
Here are the tests I've run:
1) Built in hardware test. I've had it hang while "probing hardware",
but once I run the extended tests, it always passes.
2) Disk Utility. I've verified the disk and repaired it, occasionally
I get an error, but it's always been fixable, and the last test I ran
said the HD seemed to be okay. I've also repaired the permissions several
times. There are a couple of "Warning: SUID file 'bleh' has been modified and
will not be repaired." warnings.
3) Reset the SMC controller, by disconnecting all the cables including power
and letting it sit for 30 minutes -- several times.
4) Done the Command-Option-P-R reset several times.
5) S.M.A.R.T. indicates nothing wrong with the drive.
When things go bad, there are several ways it happens.
1) Sometimes I get the grey screen, no apple or wheel. Just sits at the grey
screen forever.
2) After a couple of reboots, I'll usually get to the apple logo and wheel, but it
stays there forever.
3) After 10 or 20 reboots, I can usually get it to go all the way through
and start up.
Sometimes when I can get it to boot from the Install DVD, the physical harddrive is listed in the Disk Utility but not the "Macintosh HD" partition, so I can't check or repair it.
I have thought that this might be heat related, maybe it works better as it heats up, but this doesn't explain the inability to just restart it when it's been running for a week.
What does this sound like to you? I have to admit that I'm stumped, and since I don't really have a good grasp on what's going on at each stage of the boot sequence, I can't narrow it down to one thing or another. I guess worst case I'll take it in to the "Geniuses" at the Apple Store, but I'd like to understand exactly what's going on here.
Any help would be....helpful.

I've had totally mixed luck with hard drives in the past. I had a drive fail on me after 1 month and another last for the last 10 years. I'm not upset, assuming it doesn't happen again in 2 years.
Personally, I think the heat inside the iMac makes it a little harder on the drive, which might accelerate it's life. Once it started to go I installed "iMac Fan Control" (just google it) to keep the heat down. No idea if it milked a little more life out of it or not, but I think I'll keep running it.

Cloned volume gets stuck at boot "Waiting for Network File System"

I've used "Carbon Copy Cloner" many times with success and no problems (v 2.3 , default settings, make destination bootable) as I migrated to larger drives or make backups in advance of a major OS upgrade.
Last time I was successful, I was at OS 10.3.5. I use 3rd drive to boot my Mac, then clone the one non-boot drive to the other. I do the disk repairs & permission repairs as the normal course of this process, before & after. I am now at 10.3.9. I am do this clone in prep to go to 10.4 so I have a good back in the event of later problems.
When I attempt to boot from the newly cloned partition, it goes fine on the boot process until it hangs at the "Waiting for Network File System" step and never gets past there. I've never had this happen before. I retired all the steps, even ran "Diskwarrier", but no change.
I am not trying to run from a remote or network drive, just a 2nd drive in my
G4 from which I have previously been able to boot (until this last clone attempt that is).
I googled the symptoms ""Waiting for Network File System"", found it to be common, but no real answers. Is this one of those annoying UNIX things? Any ideas how to fix / turn-off whatever is hanging the boot up? Thanks in advance!

Hi Kool,
So there seems to be a "speed-bump" around 10.3.9. No wonder I have had the same results with a different tint. I went to Drive Genius to clone this one. Results with that were interesting.
If I did a [Device] clone, it would take and show at start with 'option' key... and work just like my internal with 3 accounts on it... login and proceed like it was internal. If I did a [Volume] clone, it would not show up at start with the 'option' key... I'd have to boot it from System Preferences > Start-up Drive. Once booted, it had no login screen so all the files were accessible. I took the clone of this 3 account PB and tried it on an iBook. Had to boot from System Preferences too, also, all the account were accessible from that machine... implying that anyone who had that drive could get past/into my files that would be secure on my computer, but not on the clone. If I took the [Device] clone and booted from the ibook at start with the option key, it would not get past the login screen... altho the mouse worked and I could click on the name, that was as far as it got, Froze.
So, I have figured, for safety, a [Device] clone is it, as long as the original computer lives. The safety features for login seem to be hardwired in the chip that the clone was made from (The iBook had 2 accounts but not my 3). If safety is not an issue, the [Volume] clone is fine... like moving to a newer OS on the same computer. It would seem from your experimentations that the situations with this 10.3.9 is just a hick-up and is solved in 10.4.3 with CCC v3...
Thanks for your info... I am thinking of going to Tiger, but I am so fond of this Panther...

Nomad JukeBox3 gets stuck upon booting

I have a Nomad Jukebox 3 with the latest firmware that recently stopped playing in the middle of a song. None of the function buttons worked; the unit was frozen. After pressing the reset button, it reboots where I can see the Creative logo and EAX logo screens then it freezes on the bitmap screen. Tried rebooting and connecting to PC many Xs without success. Worked perfectly for over 3 years.
Can anyone suggest a solution?
Thanks.

My wife's iphone 3gs gets stuck on boot logo screen sometimes with a loading circle.

I have tried holding power and home buttons to restart. Problem persists.
I have also updated software. Problem persists.
I have done a backup then a restore. It worked normally for a few hours then the problem returned.
None of the youtube videos or the advice on the web has helped so far.

I should add that I have an Iphone 4 and Itunes has no problem finding and synching my device.

Blackberry z10 help | My Mac cannot recognize the phone and my phone stuck at booting %99 for 6 hours nothing happened

My Blackberry z10 , Stuck at %99 Boot , and my Mac OSX doesn't recognize it?. i have latest Blackberry Link Version

The funniest part of the whole situation, Apple Care explained it to me as some kind of feature. The told me how to adjust the time when my computer sleeps and recommend I don't shut it down, let it sleep and "instant wake". I would bet if you called them about your Macbook, they would suggest you just close the lid and let it sleep rather than shutting it down.
Basically shutdown and restart have a problem and the solution is to not shutdown is how they explained it to me. They kept saying buzz words like "instant on" and "fast wakeup". My computer already could sleep and wakeup fast, but now shutdown and restart don't work right. I called them 3 times about it, but since they use these buzzwords, sounds like Lion is meant for a Macbook Air or a Mac with an SSD. If you have a normal hard disk, some of the saving/versions/resume features take too long to be written to the disk on shutdown. And when you start again, it takes a long time to reload the system to it's previous point.
Even if I uncheck the box to reopen windows on next start, it reopens them anyways.
If they can't give me a better explaination or some kind of fix, I will have to go back to Snow Leopard. I use my Mac in a production environment and depend on stability. They assured me before I upgraded that it would be stable and all the new saving and versions features could help my productivity. So far it's not helping me and downright annoying. You need to close all your windows before you close the program... if you have 5 windows open in terminal or textedit... every time you launch, they will launch all those windows. I just really want versions, not resume it seems.
But I can deal with it opening a million windows, just can't take it getting stuck on booting or not shutting down properly. This is a "feature" that should be fixed. LOL

Mac Pro gets stuck on the grey screen and won't finish booting

I have a Mac Pro 1, 1 recently (successfully) upgraded to snow leopard that gets stuck on the grey screen with the spinning rainbow cursor (after the apple logo and brief blue screen) and won't finish booting up. This happened after my computer froze up and I had to force quit. I checked out the forums and I tried all the all the suggestions (like disconnecting peripherals) and appropriate disk utilities, saw no errors with the HD reported, and had no trouble doing a safe boot (everything works o.k. there) or starting up from the software disk to perform the repairs. I did notice that during the repair permissions command, it gets stuck in the last few minutes, the CD starts to chug along, and everything freezes and I have to force quit. This happens every time I try it. I eventually backed everything up, erased the HD and reinstalled the OS, reset PRAM and NVRAM, but I'm still getting the grey screen on restart. Tech tool deluxe reports a "fail" on the video RAM, but everything else seems to check out. Could it be a graphics card issue? I did notice some funky visual glitches occurring prior to the breakdown. Any other ideas?

I wouldn't trust Apple Disk Utility to do a hard drive repair, but I would go with TechTool Pro 5/6 if you have that instead of Disk Warrior from Alsoft.
Clone the drive, though you should have some bootable backup clones already; repair the clone; then boot and work from that drive. Always have a working copy of the system.
And off load all your data to other drives.

Macbook pro boots past the apple logo then gets stuck on white screen

I have a macbook pro that won't boot all the way. When I turn it on it will go to the apple logo, and proceed past it then get stuck on a white screen. If you leave it on this white screen after a little while a grey ribbon will come across the top with little white squares and rectangles.

I took the hard drive out and tried to start it up with just the os x disk, and still got the same thing. I took the disk out and the hard drive out and then got the folder with the question mark. Someone said that it sounded like a graphics card issue, and if you all agree do you think that that would be something that a reflow would fix? Thanks for the input guys.

Ipad 2 gets stuck in a boot cycle

2 weeks ago, i left my ipad 2 to go to bed. when i woke up, the device had turned itself off. it was about 90% charged before i went to bed. upon attempting to turn it back on in the morning, the apple logo screen was reached and then some white text similar to cmd text appeared on the side of the screen. The text said something about NAND driver, memory= 0 and some other things i didnt catch. the device then restarted and got to the same screen again, before continuing to restart and display that screen.
I attempted to restore the ipad via itunes (latest version) in restore mode and DFU mode. Each time i got the error 1611. Reading the error codes, i uninstalled my antivirus and itunes and reinstalled itunes. i then ran itunes in windows 7 compatibility mode as administrator. I still got the error.
I took the device to my friends house who tried to restore it, in restore mode in a usb 2.0 port but got the error 1613 i think. After this we tried restore mode and DFU mode in a 3.0 port. these both failed and gave error 21. looking at this code, we then used DFU mode in the 2.0 port and the device restored and updated from ios 5.3 to 6.1.2.
the device has worked fine for 2 weeks up until today when midway through a game, it turned off and i get stuck in the same boot cycle again.
what could be wrong with it and what can be done? the device is refurbished and within its 1 year warranty.

I just can't think of any other software fixes that might work since you have done everything imaginable and recommended by Apple - at least to the best of my knowledge.
There is one sort of off the wall thing that you can try, but frankly, I don't think that it will make any difference at all. I have read here in the forum to let the iPad battery totally drain until it shuts off, recharge the battery for about a half an hour, and then try restoring again. I don't know if this is an urban legend, or if it really works. I don't see what difference that would make anyway other than you would be restoring the software after letting the battery drain.
You have restored the iOS and downloaded it again using DFU mode and that hasn't worked. My assumption would be that there has to be some hardware issue going on. A faulty connection inside the device, a bad chip.... Something non software related.

My 2009 iMac gets stuck on the grey Apple logo when booting up. It boots correctly when in safe mode. I have tried erasing the HD and re-installing from a USB installer. It says the install is complete, but after restarting it gets stuck on the Apple log

My late 2009 27" iMac gets stuck on the grey Apple logo when booting up. It boots correctly when in safe mode. I have tried erasing the HD and re-installing from a USB installer. It says the install is complete, but after restarting it gets stuck on the Apple logo again. This could possibly be an HD failure, but then why does Safe Mode still work and the USB install not work? Any ideas?

1. This procedure is a diagnostic test. It changes nothing, for better or worse, and therefore will not, in itself, solve the problem. But with the aid of the test results, the solution may take a few minutes, instead of hours or days.
Don't be put off merely by the seeming complexity of these instructions. The process is much less complicated than the description. You do harder tasks with the computer all the time.
2. If you don't already have a current backup, back up all data before doing anything else. The backup is necessary on general principle, not because of anything in the test procedure. Backup is always a must, and when you're having any kind of trouble with the computer, you may be at higher than usual risk of losing data, whether you follow these instructions or not.
There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
3. Below are instructions to run a UNIX shell script, a type of program. All it does is to collect information about the state of the computer. That information goes nowhere unless you choose to share it. However, you should be cautious about running any kind of program (not just a shell script) at the behest of a stranger. If you have doubts, search this site for other discussions in which this procedure has been followed without any report of ill effects. If you can't satisfy yourself that the instructions are safe, don't follow them. Ask for other options.
Here's a summary of what you need to do, if you choose to proceed:
☞ Copy a line of text in this window to the Clipboard.
☞ Paste into the window of another application.
☞ Wait for the test to run. It usually takes a few minutes.
☞ Paste the results, which will have been copied automatically, back into a reply on this page.
The sequence is: copy, paste, wait, paste again. You don't need to copy a second time. Details follow.
4. You may have started the computer in "safe" mode. Preferably, these steps should be taken in “normal” mode, under the conditions in which the problem is reproduced. If the system is now in safe mode and works well enough in normal mode to run the test, restart as usual. If you can only test in safe mode, do that.
5. If you have more than one user, and the one affected by the problem is not an administrator, then please run the test twice: once while logged in as the affected user, and once as an administrator. The results may be different. The user that is created automatically on a new computer when you start it for the first time is an administrator. If you can't log in as an administrator, test as the affected user. Most personal Macs have only one user, and in that case this section doesn’t apply. Don't log in as root.
6. The script is a single long line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, though you may not see all of it in the browser window, and you can then copy it.

Copy the selected text to the Clipboard by pressing the key combination command-C.
7. Launch the built-in Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Click anywhere in the Terminal window and paste by pressing command-V. The text you pasted should vanish immediately. If it doesn't, press the return key.
8. If you see an error message in the Terminal window such as "syntax error," enter
exec bash
and press return. Then paste the script again.
9. If you're logged in as an administrator, you'll be prompted for your login password. Nothing will be displayed when you type it. You will not see the usual dots in place of typed characters. Make sure caps lock is off. Type carefully and then press return. You may get a one-time warning to be careful. If you make three failed attempts to enter the password, the test will run anyway, but it will produce less information. In most cases, the difference is not important. If you don't know the password, or if you prefer not to enter it, press the key combination control-C or just press return three times at the password prompt. Again, the script will still run.
If you're not logged in as an administrator, you won't be prompted for a password. The test will still run. It just won't do anything that requires administrator privileges.
10. The test may take a few minutes to run, depending on how many files you have and the speed of the computer. A computer that's abnormally slow may take longer to run the test. While it's running, there will be nothing in the Terminal window and no indication of progress. Wait for the line
[Process completed]
to appear. If you don't see it within half an hour or so, the test probably won't complete in a reasonable time. In that case, close the Terminal window and report the results. No harm will be done.
11. When the test is complete, quit Terminal. The results will have been copied to the Clipboard automatically. They are not shown in the Terminal window. Please don't copy anything from there. All you have to do is start a reply to this comment and then paste by pressing command-V again.
At the top of the results, there will be a line that begins with "Model Identifier." If you don't see that, but instead see a mass of gibberish, you didn't wait for the "Process completed" message to appear in the Terminal window. Please wait for it and try again.
If any private information, such as your name or email address, appears in the results, anonymize it before posting. Usually that won't be necessary.
12. When you post the results, you might see the message, "You have included content in your post that is not permitted." It means that the forum software has misidentified something in the post as a violation of the rules. If that happens, please post the test results on Pastebin, then post a link here to the page you created.
Note: This is a public forum, and others may give you advice based on the results of the test. They speak only for themselves, and I don't necessarily agree with them.
