How do I abort Safe Boot when it is in process?

I am currently using my computer for this question. The problem is with my mother's computer. I was cleaning out the cache on her computer when my brother came along and shut it off (as a joke). When I turned it on again the Safe Boot process came up again, then about and eighth of the way through, it shut off. I have tried not prompuing the Safe Boot process, but that didn't work. I also tried taking the battery out, that didn't work. I even left it for a while. I don't know what is wrong. The computer turns on smoothly, and runs like it will be fine, but the, out of the blue, it goes black. There is no warning, and no shut off process (no wurring sounds). Please help me get it rumming again. Thank you.

Unless the drive is corrupted beyond any use, you need to try erasing it before reinstalling OS X:
Install or Reinstall Mavericks, Lion/Mountain Lion from Scratch
Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard 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.
Erase the hard drive:
1. Select Disk Utility from the main menu and click on the Continue button.
2. After DU loads select your startup volume (usually Macintosh HD) from the
      left side list. Click on the Erase tab in the DU main window.
3. Set the format type to Mac OS Extended (Journaled.) Optionally, click on
      the Security button and set the Zero Data option to one-pass. Click on
      the Erase button and wait until the process has completed.
4. Quit DU and return to the main menu.
Reinstall Lion/Mountain Lion, Mavericks: Select Reinstall Lion/Mountain Lion, Mavericks and click on the Install button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible
            because it is three times faster than wireless.

How to stop the safe boot mode?

Every time I start my mac by pressing the power button it atomaticly goes into safe boot mode. How can I stop this from happening?

When you get to the piont in start up where you type your password in. It says on the top right of the screen in red letters Safe Boot.

My Mac OS X 10.6.8 won't start on "Safe Boot" when holding "shift" at startup.

My computer has a kernel panic problem. And I'd like to fix it by booting as safe boot. I hold the shift key after the tone, and release it when the apple and loading gear appear. But, the bar that indicates that safe mode is loading never appears. It'll just boot on regular boot. Any answers to this question that might solve this problem will be helpful.

Work the issue from another end. Post a copy of the kernel panic report:

Maybe your problem can be identified from that.

HT201262 how long does a safe boot take?

I tried safe booting my Mac but it seemed to take forever. What's a reasonable amount of time?

How log is "forever"? Some computers are just slow booters, and can take up to a minut or two, sometimes 3 to boot at the extreme.... HOWEVER, a computer that takes, 7 - 15 minutes to boot definately has a problem.

How do you abort a Boot Camp install?

Hello,
I figured I'd give this whole BootCamp under Leopard thing a try just so I could see how it's done.
So I started the install and it rebooted to my XP CD. It says, "Press any key to boot off the CD" So I continue to press any key, but when I get to the setup screen my keyboard doesn't work at all! Same Mac keyboard I've always used and even works with my PC. It won't accept any keys so I can't continue the XP install. So I power off and and on and eject the disk. Now I get:
"No bootable device. Insert boot disk and press any key."
I don't have another Mac Keyboard, but I've tried using my PC's keyboard, which lights up when plugged into any computer. I also lights up when plugged into my Mac, but now I can't get passed the "Press Any Key to boot from CD" So it seems that I'm stuck! I can't even get back to my OSX desktop! It seems to be stuck in the middle of the Bootcamp setup, which I can't complete for some strange reason.
HELP! Even just to cancel this install. I've also tried booting off my Leopard and Tiger discs, but no go. I still get the message that the disk can't be found.
Can someone at least tell me how you abort a BootCamp install? Right now, my Mac Mini is less useful than a brick! It's a glorified paper weight! Thank God I've got another computer cause I'd really be screwed otherwise.
Very very strange that the Leopard DVD nor the Tiger CD works when trying to boot off of either one though.
Thoughts? Opinions? Ideas?
Thanks for you help!

Ok, this is very strange, but suppose I it might explain why my keyboard wasn't working during the XP install. I noticed that my Caps lock light wasn't turning on when I pressed that key. So I switched and connected my Dell keyboard and used the Alt key for Option. Then it showed me my hard drive, no other partitions like I had expected. I clicked the Hard Drive and it continued to boot up.
Now, what's up with my keyboard, it's an Apple keyboard (the new slim one with the number keypad); it works great on my Dell. But not on my Mac? Huh? My Apple Keyboard isn't working on my Apple computer? Huh? Am I in Bizzaro world here?
Anywho, thanks for your help!

How can I do Safe Boot if keyboard doesn't work

iMac frozen at restart and keyboard doesn't work. Appreciate any ideas on how I can reboot.

Do you have a wired or wireless keyboard? If you have a wireless one, using a wired one temporarily might help with this. Otherewise, it sounds like you have a hardware failure, possibly hard drive or logic board. In any case I would then recommend taking it in for a Diagnosis and service.

How do I abort the "Moving calendars to server account" process?

Running Mavericks. Calendars only update through iCloud, but I have a permanent "Moving calendars to server account message. Restarting Calendars does not abort the moving calendars process. Waht now?

Hey all, I had the same problem. Everyone seemed to have different solutions that worked for them--but not for me . Here's what actually fixed my problem.
1. Force quit iCal and Reminders.
2. On your computer, unlink Calendars and Reminders from iCloud:
> System Preferences > iCloud > Uncheck Calendars AND Reminders
(I did this because my Reminders uses my Calenders; I set deadlines for reminders, etc. Also, because my reminders weren't syncing with my iCloud as they should.)
3. It'll ask if you want to delete the calendar and reminder events from your computer. Say yes because you should already have the most up-to-date copy on your iCloud.
4. Open iCal. It should no longer display the "moving calendars to server account" message.
5. Add your iCloud account to iCal.
> Calendar > Add Account... > iCloud > Sign in with Apple ID and PW
6. Give it a minute to update. You should see all your iCloud calendar events with no error message.
7. Quit iCal. Open Reminders.
8. Add your iCloud account to Reminders.
> Reminders > Add Account... > iCloud > Sign in with Apple ID and PW
9. Test the two programs by adding test events and reminders to see if they show up on your iPhone and your Macbook.
It worked for me!
Hope this helps you!

Post safe boot ALL emails from third party URL hosting appeared

I host a half dozen websites on Hostgator. I design those websites using RapidWeaver from RealMac Software. Yosemite has disenabled several of my sites from opening, so I can't migrate to RWv6.0.1. I've been working with their HELP Team for last week, and they asked me to restart in Safe Mode (Safe Boot), which I did, although it doesn't seem to have helped with RW, yet, but we continue to slog to get there. Here's my immediate problem. Immediately following the Safe Boot, when attempting to go back to my "normal" email activity, my Mail app has now put in a new category of email that includes ALL the email addresses that I have set up for clients on Hostgator. I can see everything, and I have no interest or business seeing such. So, how do I remove all of those, except the three that are my own for use with specific client business? Thanks in advance for any assistance you all might be able to lend.

This was strange but has to do with how startup disk and nvram interact
http://forums.macrumors.com/showthread.php?t=1795765
I think your problems were solvable and not that the Sonnet card and 5,1 is not bootable, in fact the 5,1 is easier, there are more supported cards.
I have the 1,1 where the Sonnet Pro is recommended but for data only and are not bootable because of the 32-bit EFI firmware. NOT the 4,1 and 5,1. The 2008's are problem child and have a mix of PCIe 1.1 slots, first implementation of EFI64 that also has problems. Also the 4,1 has two PCIe 2.x slots 3 and 4 that share a controller but that simply limits bandwidth.
I would have left the TRIM support and NVRAM changes in Yosemite to a separate thread if you wanted to focus on the Sonnet Tempo Pro support in Mac Pro 2010-12 5,1s.
Also the make of SSD can vary and they also have their own firmware as do bootable controllers along with the EFI of the Mac, all of which have to work together. Meaning it might be that Samsung 840 va 840 EVO vs 840 Pro will all be slightly different but my experience is Samsungs work well (as do others like Crucial with the proper firmware - and there was/is an issue with the firmware of the Samsung 840 but not with booting).
The PCIe card gets seen and treated as external and therefore 'eject' but of course you can't when it is the system boot drive.
One thing I found last week and meant to mention: After installing or changing PCIe cards, RESET SMC made all the difference in the world with the long boot delay. Some PCIe cards will add a few seconds, system has to search the device tree which now shows another controller with multiple devices - and sometimes NVRAM and SMC are what I will call "dirty" and need to be rebuilt and reset.

Unable to conduct a safe boot ...

My inability to install an update to MS Office for Mac indicated a possible issue with my hard drive needing repair. I cannot figure out how to do a safe boot even after reading numerous discussion threads here. I fear I may have an even deeper problem. Here is the situation ...
I cannot safe boot using the Shift key during boot up. My computer goes through the motions and eventually turns off.
When I try to do a safe boot off of my Mac OS X Install Disk 1 (holding down the C key during boot up), it directs me into the install mode for OS X, thereby erasing prior versions on my hard drive. It does not allow me to proceed directly to a safe boot and then proceed with a Disk Utility Repair option.
If I try to safe boot holding down the Option key, it does give me the option of booting up using either my own hard drive, the Mac OS X Install Disk, or finding a Network drive. If I choose the Mac OS X Install Disk, I get dead ended in the same manner as indicated in the previous paragraph. If I choose the Network option, I do boot up, but not in safe mode.
I am not a techie and hope that I am just missing something obvious. Any help would be greatly appreciated.

Hi Soul Man, and a warm welcome to the forums!
Not that it matters that much, but for clarity, only the Shift key is Safe Boot...
"Try Disk Utility
1. Insert the Mac OS X Tiger Install disc that came with your computer, 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. (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. Click the disclosure triangle to the left of the hard drive icon to display the names of your hard disk volumes and partitions.
5. Select your Mac OS X volume.
6. 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.)
Do let us know if you need a better explanation or what the outcome of repairing the HD is.

Mountain Lion going into safe boot

Hi, I downloaded mountain lion and it started intstalling. When it restarted to install the upgrade, it starts in safe mode..i tried shutting down and restarting few times but every time it starts installing the updates and then goes into safe boot mode..
Note: yesterday I got a problem with my key board, there was a spill into my mbp keyboard and most of the keys are not working. Right now i am using my Bluetooth keyboard now.
Pls let me know how to fix this safe boot issue with the installation.

A problem with a keyboard will cause your Mac to startup in Safe Mode.
If you can, use a USB keyboard instead of Bluetooth.

TS4235 Is Safe-boot broken by FileVault 2?

OK. So, I would be performing a Safe Boot, if I am unable to get through the normal boot. Which tells me that I an unable to follow the "Turn Off FileVault 2" steps outlined. Am I missing something?

I believe the problem with Safe Boot and FileVault 2 was fixed in Mac OS X 10.7.4. I am able to perform a Safe Boot to start up in Safe Mode with FileVault enabled on a Mac running Mac OS X 10.7.4.
In Mac OS X 10.7 through 10.7.3 it appears that one either (a) could not perform a Safe Boot with FileVault enabled or (b) that no indication of Safe Boot was provided. I suspect (a) since a "Safe Boot" notification started appearing in the upper-right side of the Login Window when I perform a Safe Boot under Mac OS X 10.7.4.
I believe the AppleCare Knowledge Base article "OS X Lion: How to perform a Safe Boot if FileVault 2 is enabled" only applies to Mac OS X 10.7-10.7.3. I've sent feedback indicating that the article should be updated as it appears this problem was corrected in Mac OS X 10.7.4.
Unfortunately, no indication of this change was provided in the "About the Mac OS X 10.7.4 Update" document.

I don't think Mac OS X Lion is entering Safe Boot mode

Hi Everyone,
I always do a safe boot when troubleshooting since my first MacBook with Leopard and after installing Lion in a new MacBook Pro, I don't think I'm entering safe boot mode. I mean, I press the shift key at boot time like I've done countless times before but now I think my MacBook Pro is not booting safe.
Namely: I don't see the words "Safe Boot" on the login screen, it doesn't take longer and the pinwheel is not replaced by a progress bar when booting.
Can anyone please tell me what's going on?
Thanks in advance!

When I tried to run the Apple Hardware Test and couldn't start it with the "D" key, even though the "Alt" key and "Cmd+R" boot options did work, I started getting more suspicious.
I reset the PRAM and that fixed my issue.
For the record, the words "Safe Boot" on the login screen did not appear, but the progress bar instead of the pinwheel did.

Safe boot: what is this ?

hi friends,
I had a number of updates to do yesterday, so had my 13" macBook Pro running to download them and that worked all well. At the end of the updates it restarted but ever since I have the Grey Screen of Death.
Tried booting is safe mode, which seems to work as there is a bar coming under the Apple logo, but once the bar is filled after about 2 minutes the grey spinning cogwheel comes up indefinitely, leaving the screen grey. tried resetting the two abrrevaition (DVRAP or so and something else), but did not make a difference starting it up that way as it just keeps showing the spinning wheel on the grey screen.
Before I continue and reinstall from the Install DVD, would it be that the bar that is being filled in safe boot is a sign that in itself it is working? Did I give it not long enough or how long should a safe boot take?
Also, at what time time to push the SHIFT button at startup? Is it OK to hold the SHIFT button from the moment I push the power button or should I push it later?
Gratfeul for your help, thanx

Chimes, no video, no boot when video card installed. Cause?

Dual G5 2.0 (late '04?)
Used for 5 years, then system started suddenly powering off. Eventually wouldn't boot. Tried swapping out ATI X800XT vid card for a 9600 (both AGP) & it worked again for a couple days, then wouldn't boot again. Put it aside for a while, came back to it yesterday, and came to these conclusions:
1) with X800XT installed, the system (PSU) clicks once, then nothing. no chime, no lights, no fans.
2) with 9600 installed, it chimes, power light on & steady, fans start, I hear the HDD click once, then nothing. no video out. eventually the fans go into overdrive.
3) WITHOUT a video card, it chimes, light on, fans OK, and I hear the HDD running through what I assume to be a boot sequence.
4) I have reset the PMU and replaced the battery. Also tried CMD-CNTL-O-F. Nothing.
Thinking it might be the power supply? Where do I go from here to diagnose the cause?
If it's the logic board, I'll tear out the guts & sell on ebay. If it's the PSU, I've read about someone replacing it with a standard PC ATX supply (don't want to spend the $$ for a G5 PSU.)
Thanks for any suggestions!

OK, assuming you have file sharing enabled, when you bring the machine up without video card, can you connect to it from another computer on the same LAN?
The fact that either video card blocks the boot is suggestive of maybe a power supply problem, though in my experience an overload condition perceived by the power supply will result in a click from the supply and the machine powering down completely.
That was a situation I had some time ago before replacing the supply. What would happen was that in a non-safe boot, when the kexts for the Ultra6800 loaded, the current draw would increase and the supply would trip itself off. (Puzzling mystery solution revealed just now in formulating the reply. Thanks.)
That being said, the fact that safe boot doesn't help plus the other differential symptoms between the cards really does suggest a failing power supply. A new supply around the web is on the order of $200, but there are plenty of used ones on eBay for much less, occasionally even a new one goes at a bargain.
One thing you could do is blow the probably well-stocked dust supply out of the power supply. Better to remove and do that outside, but you can make something of a dent with the power supply in the enclosure. Just be sure to do it outside, because the dust that can come out will probably be pretty nasty. (Of this I have personal experience!) Of course, under what you have reported, this has a slim chance of actually helping.

Hello, what OSX version?
Could be many things, we should start with this...
"Try Disk Utility

2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu at 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.*

(Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive.)
If perchance you can't find your install Disc, at least try it from the Safe Boot part onward.
If 10.7.0 or later...
Bootup holding CMD+r, or the Option/alt key to boot from the Restore partition & use Disk Utility from there to Repair the Disk, then Repair Permissions.
If that doesn't help Reinstall the OS.
