Mini not starting in safe mode

i restarted the mini while holding down the shift key, it went to the apple with the spinning thing below it for a couple of minets then shut off.
i just recently did a PMU reset. could that have affected it?

Boot Lion Recovery or your OS X DVD (or create and install OS X on another hard drive).
When Safe Mode won't work the freeze probably affected more.
Try the MacBook Pro and Lion Community forums.
you can use Disk Utility : Restore to clone your system to another hard drive from which you can boot.
Do you need one file?
What did you boot from to access Disk Utility?

My IMac 24" intel will not start in safe mode.

Did a Shift - Command-V and the black screen showing all the startup steps appeared and it all looked good except: AFL Alart Sockwed cant update and INIT Reboot transmit failed. All else looks good. I have tried this 3 times and never go past that point. Then the screen turns off white like it does when it starts normally before the apple appears and the last time the screen went black.
I have tried starting with just the Shift Key and computer starts up but not in safe mode.
I have tired starting with the OS X disk and the C key and it will not recognize the disk.I used the #1 disk since the instructions are printed on the disk. Did not work so I tried disk 2 and I get a menu to start the OS or tools. If I click on either one the screen goes white and stays that way.
computer starts fine and provides a login window, and then the desktop screen with screen saver pictures in perfect color. As it goes through starting programs it starts the same programs that is had open when the computer originally crashed. Even when I close them, before it locks up again, and I am forced to restart the same programs open up to the same place. Its like the computer is frozen in one location and will not go beyond that point. Eventually the screen turns white and sometimes black and sometimes gray.
Tech support thought it was the video card, put a new one in but did not fix the problem and then said it was not that but that it was the monitor. I said that did not make sense since the monitor and desktop icons and pictures are beautiful and clear. They then said it was the inverter board on the monitor and Apple only replace the whole thing. I purchased an inverter board and replace it. No change. The tech person said that the computer works find without the monitor connected - I will see if that is correct next. Isn't that a more systimatic testing procedure then trying parts to see if it works? Oh I did do the complete long hardware test. Took about an hour and it passed! Isn't this strange?
I have to replace a monitor that has perfect color and image if it is something simple to fix or replace. Has anyone ever encounter anything like this? Could it be a virus?

As you probably read everthing was working fine for over an hour so I shut down and put everything back together completely, all monitor screws, aluminum cover and screws and screen cover, unplugged the external monoitor, plugged in external HD's and turned on the computer and guess what the old problem returned. So I unplugged the external HD's and plugged in the external monitor and took the screen cover off and restarted the computer and guess what it is working fine. Doing a disk utility verify first then if no problem I will unplug the external monitor if all is good then I will plug in the external HD's if all is good I will install what I believe is the problem the monitor cover screen.
Your post about the Temp sensor and another post about the cable to the monitor with the temp sensor has me believing that the monitor is getting too hot for the fans to cool down or the sensor is faulty. Which one is the temp sensor? It is the monitor cable that has the little box at the end that screws to the logic board?
How do you know if the secsor is bad or the monitor is overheating and the sencor is working correctly? Is there a test?

New widows 7 install on amd phenomx6 64 bit firefox 3.6 crashes as soon as it is started also will not start in safe mode it crashes before it starts. it will run when windows is in safe mode

this is a brand new system from zt systems. it came with almost no software installed. no toolbars or anything, only trial of microsoft office.
I don't think that it even generates a crash report.

MacBook Pro 13 2010 running Mountain Lion: will not boot and shows a folder with a flashing question mark. Will not start in 'safe mode' i.e holding shift on start up - nor can I call up any utilities with the OSX shortcuts. Any thoughts?

Following an automatic update, the machine wouldn't boot. Screen came on (shows white) - then either showed a 'No-Entry' Sign and a spinning cog, or a folder with a qusetion mark. I tried to start the machine in different modes ( eg. holding shift after the tone ) but nothing worked. after leaving the machine alone for 1 hour. It worked perfectly again. I did a 'verify disk' check which found no problems. 2 hours later it then froze ( In - Photoshop). Could not force quit, so shut down, and have not been able to boot again since (white lit screen - flashing folder with question mark) . I have also taken the hard drive out and checked the connections which seem fine. Any suggestions? - Is the Hard Drive dead. : other info : It was also running parallels 8, with Windows 7. at the time of the update....

This article may help: A flashing question mark appears when you start your Mac.

Will not start in safe mode

Using PB G4 15 in. Trackpad froze and then machine auto shut down. Restart failed. V boot failed. Pram boots all failed. Has reached apple screen once but froze and auto shut down again. Please help.
Ps note sure which OS as can't power up to check. Was fully updated

can you be a little clearer in what you have done so far?
by v boot, do you mean booting to Verbose mode? and PRAM boots - the system shouldn't boot when you reset the pram, it will clear the contents of the PRAM and reboot back to the chime when finished.
sounds like it could be a hardware problem - maybe a hard disk problem. Apple recommend booting from a disk first and using Disk Utility to repair the disk. If you can't do this try booting to single-user mode (hold down cmd-s on start up) and use the command 'fsck -fy' and then issue 'reboot'.
If that doesn't work try booting from an external disk or mac through traget disk mode, if possible. if not, take the machine to the nearest service centre.

Mozilla updated last night and now crashes on update. It does not start in safe mode.

I run WIndows Vista and have never had a problem with Mozilla before.
This happened two nights ago as well. My IT departmnt does not support Mozilla but last time agreed to install a previous version. Problem solved. They will not help again. Is there a fix for the new version? Or...where can I get the older version?

My Mac Pro 2.8 crashed and will not reboot in Safe Mode - HELP!

Hello
I have a Mac Pro 2.8 and it froze up on me; I held in the power button to shut it down. Upon restart, all I get is a flashing foldoer file icon with a question mark.
What gives? It will not start in Safe Mode, via the Shift button OR DOS command (sudo nvram boot-args="-x")
1. How do I get it back up? I have a back up on my external hard drive, but it doesn't recognize it?
2. Are all my current files gone?
Thanks for your help

A flashing question mark on boot can mean several things. One, your Mac can't find a system folder to boot from or the startup disk is failing or failed.
Since you don't have the install discs now, it may take some time to order and receive them from Apple. Probably time to take the Mac to an Apple Store or Apple certified repair shop. They can tell you for certain whether or not the disk has failed.
Since holding down the Option key that prompts the Startup Manager window didn't work, not does your external drive recognized your Mac, I'm afraid without a backup to restore those files from, you may be out of luck.
can I get a new one from mac, and will it erase all my files?
You can get replacement System Install & Restore CD/DVDs from Apple's Customer Support - in the US, (800) 767-2775 - for a nominal S&H fee. You'll need to have the model and/or serial number of your Mac available.

Have an old mac mini 2008 running OS x 10.6 Whenever I shut down or restart it won't find the dell screen again. Have tried with different screen same result.

It has all my daughters exam work on it which she, of course, has not backed up so any suggestions gratefully received.

Firefox crashed and now will not start. Cannot create new profile or start in safe mode because Mozilla Crash Reporter appears and will not restart.

Browing the web, Firefox crashed. Typical "this is embarrassing" window appeared and I could choose to restore or start new session. I tried to restore, and nothing happened. Mozilla Crash Reporter appeared, the option to quit Firefox seems to work but restarting just brings back the Crash Reporter. I tried uninstalling and reinstalling Firefox, but Crash Reporter persists. I tried looking through your articles on crash on startup, but I cannot open Profile Manager, nor start in safe mode, nor anything else, with that Crash Reporter popping up. I can't give you a crash ID as I can't type anything into Firefox address bar if I can't open the program. I'm running Windows 7 starter edition on a netbook. Honetly really only use Firefox on this machine, so help would be appreciated! Thanks.

Maybe you did't understand my previous statement. There are no crashes in FF 3.6, There is no previous evidence FF 14 was ever here, I completely uninstalled all trace of Firefox, no app data, no preferences, no cache. I will upgrade to FF14 so I can send IDs,
so here ya go.

Having upgraded to Firefox 24 it will now not start at all after clicking on the icon. My OS is Windows Vista premium. It will start in safe mode.

Upgraded to Firefox 24 and now nothing at all works despite uninstalling and reinstalling it several times and losing all my bookmarks etc. However it does start in safe mode. At first I thought it was my security Norton 360 but after 2 hours in contact with them I'm still in the same position. When I double click on the Firefox icon I can see the cursor timing out and then it just disappears and nothing loads.
My OS is Windows Vista Premium and I am using Windows internet explorer at the moment.
HELP please!!!

My MacBook Pro doesn't start; in safe mode shift CMD V the message "disk0s2: media is not present" is written on the screen repeatedly but the MacBook doesn't start. Do you have any ideas of why this should be or what I should do to resolve this?

My MacBook Pro doesn't start; in safe mode <shift CMD V> the message "disk0s2: media is not present" is written on the screen repeatedly but the MacBook doesn't start. Do you have any ideas of why this should be or what I should do to resolve this? Thanks Eamonn

Thanks for these suggestions: I have tried safe mode re-starts (both "verbose" and simple "shift" + power) to no avail. I get the error message "disk0s2: media is not present". Following this I inserted the installation disc and from there ran disc utility. The "Verify Disk" indicated an error " invalid sibling link" which it could not repair.
I also tried to completely re-format/erase the disk, but again got an error message "disk object invalid or unable to serialize".
Any ideas of what could be causing this or the best solution? I fear I am fast running out of options.

MacBook pro will not boot. I get the gray screen, an apple icon and spinning wheel. Tried to start in safe mode but get the same screen. The only thing different was that I loaded the zedge sync app yesterday. Now getting this problem.

Macbook pro will not boot. I get the gray screen, an apple icon and spinning wheel. I tried to start in safe mode, but get this same screen. The only thing different is that I added the zedge update app to do a sync for adding ringtones to my apple cell phone. How can I get a good boot. I am fairly new to apple computer.

Reset PRAM: http://support.apple.com/kb/PH4405 and then try a normal boot.
Run the Startup Manager to select Startup disk: http://support.apple.com/kb/HT1310
If those did not work your disk may be sick or dying. The top priority at this point is to make a backup copy of your data.
Check the health of the disk. Boot in Recovery Mode (Boot, Command-R). Run Disk Utility. Click on the upper left disk icon. Does the S.M.A.R.T. status say “Verified”? If not the disk/SSD is unhealthy and needs to be replaced. Even if it does not show “Verified” you can still attempt a backup.
Click on the icon indented below, usually called “Macintosh HD” and Verify Disk. If it finishes with a green “OK” message then all is well with the disk. If it shows errors in red then you have found a problem to address once the system is backed up. Do not attempt software repairs until you have secured the data.
If the disk will not show up at all in Disk Utility as your ran the tests above then it may be dead or it may have a bad internal SATA cable. A trip to an Apple store for confirmation would be in order.
If you have an external disk drive you can use as a backup drive then do so. If not Google “Hitachi USB 3.0 external hard drive 1TB” to purchase one or go to a brick-and-mortar store (including an Apple store) to pickup one. Any 1 TB external drive will do.
Assuming it is still breathing you can try to recover the data without booting from the sick disk.
Reformat the external disk. (This will erase all data on the external disk.)
Boot in Recovery Mode. Start Disk Utility. Plug in the new disk. Select it’s disk Icon (the second one down, left justified). Select the Partition tab.
Partition Layout > Single Partition
Name: Emergency Recovery 1 (or whatever name you wish to use)
Format: Mac OS Extended (journaled)
Options… > GUID Partition Table > OK
Apply
Select the Restore tab.
Drag the old system volume (Macintosh HD) to Source.
Drag the new disk volume (Emergency Recovery 1) to Destination.
Click on Restore.
It may take a long time for the backup.
If that will not complete post back for other emergency data recovery methods, including those from a brody.
If the backup succeeds, use the First Aid tab in Disk Utility to select the old volume (Macintosh HD) and Repair Disk. If it does not finish with a green OK message try to repair it once or twice more. If it repairs with a green OK message, will it boot normally? If not, boot from the Recovery Partition and reinstall OS X.
If it is still not healthy, post back for further instructions.

Firefox used to work on my windows 8 machine, now it does not, even starting in safe mode and after un/reinstalling. message "firefox has stopped working".

Firefox used to work fine, then a few days ago it just stopped. When I try to start it, it comes up with a message that "firefox has stopped working". That message comes up over the box that asks if I want to start in safe mode or reset firefox. when i try to close or cancel that message so I can try starting in safe mode, both sets of messages go away.
if I try to start in safe mode using the shift key, the same thing occurs. The same thing occurred after I uninstalled and reinstalled.

Do a clean reinstall and delete the Firefox program before (re)installing a fresh copy of the current Firefox release.
*Download the full Firefox installer and save the file to the desktop http://www.mozilla.org/en-US/firefox/all.html
If possible uninstall your current Firefox version to cleanup the Windows registry and settings in security software.
*Do NOT remove "personal data" when you uninstall your current Firefox version, because this will remove all profile folders and you lose personal data like bookmarks and passwords including data in profiles created by other Firefox versions.
Remove the Firefox program before installing that newly downloaded copy of the Firefox installer.
*(32 bit Windows) "C:\Program Files\Mozilla Firefox\"
*(64 bit Windows) "C:\Program Files (x86)\Mozilla Firefox\"
*It is important to delete the Firefox program to remove all the files and make sure that there are no problems with files that were leftover after uninstalling.
*http://kb.mozillazine.org/Uninstalling_Firefox
Your bookmarks and other personal data are stored in the Firefox profile folder and won't be affected by an uninstall and (re)install, but make sure that "remove personal data" is NOT selected when you uninstall Firefox.
If you keep having problems then also create a new profile.
