Mac Pro won't boot into safe mode

I tried to boot into safe mode by using the keyboard key and the progress bar got a little bit of the way across but then it got stuck and sat there for 2 days with no change. Any idea why no safe mode? Here's a photo of the screen how it sat for 2 days:
https://dl.dropbox.com/u/23232804/no%20safe%20mode.JPG

Here's the few lines right around the boot attempt: at 1pm on 12/31 I tried to boot into Safe mode, then seeing that it was taking forever, I left, and came back on 1/2. It was in exactly the same spot so I rebooted normally. Does this give any clues?

Macbook Pro won't boot into safe mode or via bootable USB key

Hi,
Am running OSX Lion latest version on my Macbook Pro 4,1 and can't get the thing to boot from any source. Always get's stuck at the grey screen with apple logo. Have tried all the following...
- Straight Boot (power on)
- Boot via Recovery HD (hold option on bootup then select)
- Boot via Safe Mode (Holding Shift on bootup)
- Boot via Safe Mode Verbose (Shift, Command, V)
- Boot via bootable Lion USB Key (Hold option, and choose the USB drive - not the same USB key works on my other macbook pro)
On every one (except verbose) it just get's stuck on the grey screen with spinning timer thingie.
I have done PVRAM reset, SMC reset and have reseated the RAM and all to no avail. I'm pretty sure the problem was caused by removing battery at wrong time (device not responding after sleep mode started and I plugged in power - should have been more patient!)
I have a Time Machine backup but it's a bit older than I thought and very much want to get my newer photos off it before rebuilding - not that Time Machine would work in current state anyway.
So what are my remaining options? Will I have to open it up and remove the HD as next step or is there anything else left to try? Can I remove the HD and connect it via a USB caddy to my existing Mac to recover info (hardrive spins and sounds ok to me)?
Any advice appreciated...

Yes, once the data is off you can use Disk Utility to Erase the entire drive (Lion + Recovery) with the Zero option (one selection below 7x) then use the Lion USB to install it fresh and stick it back into the machine.
Thanks for the info - I removed the HD and data is all ok on there so very happy about that. Before I wipe the data (all backed up now) I thought I would try booting the mac without any harddrive installed - using a OSX Lion bootable USB. However, still can't get past the grey apple screen and circle icon whirling away. I know the USB works ok, as tried it in my 2011 Macbook Pro and it boots absolutely fine.
I am happy to wipe the HD now and start again, but seeing as the DVD Drive is broken I'll probably need a USB drive boot to install OSX onto the wiped HD anyway. I'm a bit lost as to what to try now.

Won't boot into safe mode

My 2012 iMac 27" was randomly rebooting itself, while in Sleep. I assumed this was due to the cheap 32 GB memory I bought, but before I could change it back to the original memory, to test, the Mac booted into Safe Mode (I assume - a progress bar showing at the bottom of the boot screen, below the Apple logo), and did not get further than a half the way, and then shut down. I swapped the memory to the original 8GB. I tried booting again, no buttons held down, as then it wouldn't get further than a quarter of the way. Further attempts to boot do not work, even when holding down Option to choose the boot disk, pressing Shift for Safe Mode, or Option-S for Single User Mode. I assume it's trying to boot in Safe Mode, but failing?
I also tried using a good Mac with the bad Mac as the Target Disk boot mode - the good Mac does not see the bad Mac...
I have an external DVD drive, but that isn't an option as I can't go into boot drive select mode. What are my options, apart from sending the iMac back?

Booting into the Recovery HD should allow you to effect repairs - that's the point of it, so it's a bit concerning that it won't allow you to. The Recovery HD is a partition on the internal drive that should allow you to effect repairs to the Macintosh HD, albeit part of the same physical disk.
I'm no expert, but I'd be concerned that the hard disk is on the way out. Do you have backup of everything - Time Machine or a bootable clone, perhaps?
Maybe have another try with Command+r. If it fails I'm not sure what would be the best next step - it depends if you have a full and up-to-date backup of your disk so that you can restore.
One of the options of the Recovery HD is to allow you to re-install the OS, which won't delete your data.
The more extreme step would be Internet Recovery which would involve erasing everything and re-installing via the internet.
Worth reading this carefully before proceeding: http://support.apple.com/kb/HT4718
Disk Warrior from Alsoft (not cheap) is another possibility for recovering damaged disks, although it's not a guaranteed solution.

Hard drive won't boot into safe mode

My mid 2010 Macbook Pro has suddenly decided to not boot up after installing BitDefender and running a scan.
I installed it on a whim when I saw minor malware that hijacked Safari, and decided to run a scan. While I was working on Photoshop, the scan must have finished because all of my windows disappeared and I was left with my desktop and the spinning gray loading at the bottom of my screen. I waited 20 minutes, realized it wasn't going anywhere and force shut down the Macbook by power button.
Now, I cannot successfully get it past the grey apple loading screen. Attempting to boot into safe mode still leaves it at the same screen. Tried to reset the PRAM, still can't get past the loading screen. I still have my OS disk, however it is Snow Leopard and my current is Mavericks and I'm unsure if it is a wise idea.
15 inch mid 2010 Macbook Pro running OS X Mavericks, how dead in the water am I and how much would this cost me to "fix"?

Use the original Snow Leopard installation disk and start the MBP as if you were going to reinstall the OSX. Early in the process you should see a menu bar on the top of the display. Click on UTILITIES and from the dropdown menu select Disk Utility. Run Disk Utility>First Aid, Verify and Repair. If it is not successful, the HDD will have to be replaced.
Ciao.

OS hangs at grey startup screen, won't boot into safe mode

I rebooted my G5 this morning and when it came back up, it hung on the grey screen with the Apple logo and the spinning 'gear' progress bar. I tried rebooting several times, but that didn't help. I tried booting from the install DVD (which it did) and ran disk utility (both verify & repair on the start up drive and on permissions. It claims to have found permission errors and fixed them.) I hunted for answers online and tried to boot into safe mode, which did not work.
Someone mentioned booting into verbose mode and I saw that the load sequence was choaking on the login.
What could the problem be and how can I fix it?

Hi Yosarian,
Minor permissions repairs are no concern: The good news is that your data is probably OK.
Three things can be happening: Some of the machines boot settings are corrupted, or the OS files or settings are damaged, or there's a hardware problem.
Resetting the machines power management chip, called a PMU or SMU, depending on your computer, and the PRAM will resolve machine boot settings problems. Run a google search for your model of Mac plus reset pmu OR smu for instructions. After that, reboot your computer and hold Option-Apple-P-R down as you power on. Hold all 4 keys until you hear the startup chime a second time.
You can test your hardware with the grey disk that came with it that ays AHT in little letters. Boot from the CD and run the extended test. Be patient: AHT can take a long time to boot and run.
If you reset your PMU and PRAM and pass a hardware diagnostic but still can't boot normally, in safe mode, or in single-user mode, the problem is system software. Reinstall from your latest installer, checking off Archive and Install and Preserve Users and Settings from the Options screen available at the screen where you choose which disk to install to.
Good luck,
John

Macbook Pro Won't Boot in Safe Mode...it also won't stop trying to boot in safe mode

I was having an issue with Finder crashing on my Macbook Pro. After startup Finder would give me the spinning wheel of death if I clicked "about this Mac." To try to resolve this issue, I attempted to boot in Safe Mode, but it basically died each time when the progress bar reached around 20%. I was able to get into the Disk Utility and attempt to repair, but I learned that I need to back up and restore. (I tried this twice.) However, my machine will now only attempt to boot in Safe Mode (at which point it reverts to dying at around 20%). How can I back up my machine if I can't boot into either safe mode or regular mode?
(P.S., If you can't tell, I'm not hyper computer literate, so simple explanations will be most helpful. Thanks!)

dullman82,
as you’ve discovered, the option to back up is currently unavailable to you with your disk in its current condition. You can try these two possibilities:
Install OS X onto an external disk, boot from your external disk, run Software Update to get it up-to-date in its version, and try backing up your internal disk when booted from your external disk;
Boot into Recovery mode, and select Reïnstall Mac OS X to reïnstall OS X on your internal disk (which should leave your other files there untouched) to see if that will fix your Finder problem.

MacBook Pro won't boot - tried safe mode but it went to black screen after trying.

my MacBook Pro froze after the fan was running very loudly. I turned it off and try to reboot but just got a gray screen. I tried to boot in safe mode but that did not work.any other thoughts on what might help?

Reinstalling OS X Without Erasing the Drive
Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Reinstalling OS X Without Erasing the Drive
Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility and press the Continue button. After Disk Utility loads select the Macintosh HD entry from the the left side list. Click on the First Aid tab, then click on the Repair Disk button. If Disk Utility reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit Disk Utility and return to the main menu.
Reinstall OS X: Select Reinstall OS X and click on the Continue button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.
Alternatively, see:
Reinstall OS X Without Erasing the Drive
Choose the version you have installed now:
OS X Yosemite- Reinstall OS X
OS X Mavericks- Reinstall OS X
OS X Mountain Lion- Reinstall OS X
OS X Lion- Reinstall Mac OS X
Note: You will need an active Internet connection. I suggest using Ethernet
if possible because it is three times faster than wireless.

Serious imac problem. Won't boot into safe mode, can't click anything when os loads up.

I'm trying to recover my files through the boot camp option on the windows side. Is there anyway to run something like disk warrior or windows alternative to repair the partition from the windows side. I don't think I'm going to be able to get all the files off my computer cause the hard drive is messed up and not working well. But I'm not completely dead. Safe mode won't work and I tried the fsck from single user which didn't work either. Any help would be great, please save my wounded mac!

I didnt change anything. Literally nothing. I am typically pretty good with computers but this is kinda driving me crazy. I didnt mess with anything in disk utility or partition sizes. I installed boot camp years ago so i dont really understand why i was moved to this forum. I use it for music production and web surfing. (windows for a little gaming) but havnt gamed or installed anyting in.. a month or longer.
I am thinking the hdd is having a problem. I never did anything with permissions which i heard could get messed up. But i cant do anything on the Mac side now just a spinning ball.

Mac Pro won't start in safe mode

In order to solve another problem in Garage Band, I tried to start my Mac Pro up in "Safe Mode," But the status bar wouldn't get past about 40%, and the computer froze up. Tried it twice, same result each time. I don't really see a problem here, unless it indicates something bad. Anyone have an opinion?

Boot from your installation disc. Select Utilities > Disk Utility from the menu bar. Select the boot volume and run "Repair Disk" (not "Repair Permissions.") I'm assuming you have backups; if not; back up first.

Computer won't boot into safe mode

It will boot up normally but not in safe mode. I recently upgraded to 10.6.6 and I was removing fonts and FontBook per Kurt Lang's article.
I get a spinning icon and an empty "no" slash symbol (?).

Ok, silly question, but I got burned by this a few weeks ago -- are you sure that the 'command' key and the 'S' key both work on your keyboard? Like when you are booted up and logged in, and you open a file in TextEdit, command-S is the keyboard shortcut for File->Save -- does it work?
(In my case, the command key on the left side of the spacebar was broken, while the one on the right was fine. Keyboard is now in trash!)

IMac won't boot into safe mode

Hello. I hope this is the right forum.
I have an iMac (2010 ish) that recently encountered system slugishness and then eventually would not start. All we got was the white screen, the apple logo, the spinning gear and the progress bar. It is currently stuck on the white screen with the aple logo and the spinning gear after trying to start in safe mode. Do any of you kind folk have some suggestions on what to do next? Thanks in advance.

Thank you for your reply. I have just attempted an AHT where I followed the instructions for OSX 10.7 and above. I chose this, even though I have the 10.6.4 Install disk because we upgraded this computer to 10.7. The machine did not do the test. It just repeated the same behaviour as before, white screen, apple logo, spinning gear and progress bar for several seconds and then the bar dissapears. Should I have tried the AHT by using the install disk as noted?

Can I ssh to a Mac that's booted into Safe Mode?

I'm needing to ssh to a Mac that's been booted into Safe Mode (I'm already able to ssh to it in normal boot mode, and I know how to boot it into Safe Mode from the command line, i.e. sudo nvram boot-args="-x", then sudo reboot).
I can't just test this for myself, as it has to work first time, otherwise I'll be locked out of the remote Mac. If ssh would still work in Safe Mode, the plan is to then ssh to it and issue the command to set it back to normal boot mode (with sudo nvram boot-args="") and then reboot... job done.
Ideally, but not too important, I could VNC to it in Safe Mode instead, but ssh would do fine.
Does anyone know (for sure!) please?
In case anyone wondered, I'm wanting to do the Safe Boot because I'm told it can cure an issue with Adobe CS apps freaking out and locking up, crashing etc. I want to try this over the w/e, and have no physical access to the Mac. I've already set it to power on later (via pmset) - something I do routinely.
I thought an answer to this would be easy to find, but after Googling I've drawn a blank. Can't find it in any Apple docs either.
Thanks in advance!

If this was already covered somewhere else, I
apologize. I did some browsing for this topic but had
no luck finding anything...
Anyhoo, I'm trying to log in to my wife's B&W G3
(running Jaguar) from my G4 (running 10.4.2) using
secure shell but she doesn't have a password set up
on her computer. When I enter the ssh command in
Terminal, it asks for a password — I don't enter
anything and just hit the Return key. It returns with
a massage saying "Permission denied, please try
again." What can I do to log in w/o setting up her
machine with a password first?
If you want to use SSH securily I would suggest you disable password authenticaiton altogher. If you setup public key authentication it is more secure and better than using passwords anyway.

Intel Mini will only boot into safe mode - hangs on ANY Mac OS volume

I have an Intel Mac Mini... the core2duo 1.83GHz or whatever.
I acquired it from it's previous owner, as it was "broken".
He could not get it to run an install disc.
It will not boot any of the Mac OS install media (DVD or CD - 10.4, 10.5, 10.6).
It will not boot/install a Linux disc (I haven't tried, but that's what I was told).
It WILL boot/install Windows !?!?
So... anyway, I removed the HDD, and installed OS 10.6 Leopard on it (FW Target mode installs kept failing at the end - regular retail DVD). I then reinstalled the HDD back into the machine.
The system keeps hanging at the same point it would when trying to boot an install DVD - after the screen turns blue, it goes back to the gray screen, then immediately freezes.
However, I eventually discovered that it WILL boot into safe mode !
Everyone kept saying it's the logic board failure, but if it boots into safe mode, can that be true ? It doesn't seem to me that it would be hardware based in that case - unless it's just a specific component, like the Airport module or something.
The last line displayed in Verbose mode when it hangs is:
"athset_txchainmask[5124] sc->sc.config.txchainmask 5 mask 5"
It also says something about the Airport just before that.
I tried removing the Airport module and it still hangs.
I also tried different RAM, with the same results.
I ran the 10.6.2 combo update in Safe Mode. It still hangs. Haven't tried 10.6.3 yet, though I do have it downloaded and ready to install.
This thing is driving me crazy. Please tell me there's a fix, OTHER than replacing the logic board ?!?! It just doesn't seem like it should be so complicated considering that it runs in safe mode.
It's rare I can't figure out a Mac problem - please help !

Very strange, and getting stranger !
Ok... so, from safe boot mode, I installed Windows XP Pro using the boot camp assistant.
Everything installed perfectly. I started up from Windows, and put in the Mac Mini recovery disc, in order to load the drivers. The Boot Camp software started with Auto Run, and I clicked through to install everything. The drivers start loading...Windows reacts positively, with the system tray announcing "new hardware installed" every 30 seconds or so. Airport/WiFi IS working (in Windows), as it detected my router/network...this is where it gets F'ed up - when the installer gets through with the drivers, and installs the boot camp software for Windows - the system reboots, goes through the usual Windows startup...the desktop background appears, but no icons or start menu - then it reboots again...same thing, again, over and over in a loop.
Went back into OS X (safe boot mode). Installed reEFIt (a bootloader utility), to see if maybe I can bypass the Mac OS/Boot Camp bootloader. No luck. Install worked, but still had the same issues.
For the heck of it, I try installing Linux Mint 8. The live CD starts up OK, but only as far as the boot menu. I tried the installer first - after the splash screen, it hangs on a plain gray screen (w/o the normal linux installer language selection menu - just solid grey).
I tried running the live CD w/o the installer - the actual OS. Same thing - after the splash screen, it hangs, only it's a black screen this time. If I use verbose mode, it still seems to hang on the WiFi card.
Here's the strangest thing yet - Ok, remember, it wouldn't boot normally into ANY Mac OS volume - including the installer DVDs - only in safe boot mode...
So, I try the "hackintosh" IPC osX86 10.5.6 DVD - it boots into the installer with NO problem, WITHOUT safe boot mode ! I tried installing it unsuccessfully. I forget now which options I choose, if any, though I may try it again later and pretend it's just a non-apple PC with the same specs as the Mini (or try just the "base system", and the bootloader - then run the official Apple updates)
This last thing really makes me think it has something to do with the EFI/bios - however, I've only been able to find info on how to update it, not replace or restore it - and it's only from a working install, not forced from a flash drive or CD (plus when I do try the installer from safe boot mode, it says it's current and unneeded).
I still haven't changed the hard drive. After almost successfully installing Windows, I made the assumption the -hardware- was OK, and reassembled everything.
Currently, I'm trying a direct installation of Windows XP Pro SP2 with which I'll try installing the drivers WITHOUT the boot camp software, to see if the WiFi (Airport card) and everything else is indeed working OK (remember too that the system passed ALL the ASD 3S116 tests).
So anyway, that's the current status. Any new ideas anyone ?
Thanks.

YT2 Pro Volume button stuck/boots into safe mode

The Volume down button is stuck on my YT2 Pro and I think this is the reason it now only boots into safe mode. At first I thought it was an app so I cleared the cach and uninstalled the last 3 apps. That did not make a difference. Stil thinking it was a application problem I did a factory reset, nope, still boots into safe mode. Thats when I noticed that the volume down button is not working. Anyone else have this issue? I am calling Lenovo today, w/ the Hard Reset issues and now the volume not working, I think the tablet needs to be replaced.
Solved!
