Not booting in Safe Mode
Hi all,
I have problems with a G5 desktop machine running 10.4.11. Disk Utility came up with an error message "invalid sibling link".
Tried to boot G5 from Tiger install DVD. Did not boot from DVD. Tested drive with other DVD's, to make sure drive is OK.
Tried to boot in Safe Mode, but after restart the spinning gear won't come up, even after holding down the Shift key for > 10 minutes. Fans run like crazy. Startup stalls showing grey screen with Apple logo.
What can I do?
You could try booting in single user mode, then write in the
appropriate command (text) to restart normally. Or maybe
there is a command to have it run SafeBoot while in single
user. Seems to me there is a similar result available when
a command line is used; however I do not know this stuff.
boot in single user and restart 10.4 - google search
http://www.google.com/search?hl=en&q=bootin+single+user+and+restart10.4&btnG=Search
There are a few support documents and other information
in the above search result link.
There may be a way to get your computer's attention
by starting up and resetting PRAM on startup, by
holding Opt, command, R , P until the machine chimes
three times, then let go of these. Could also be some
other issues where the power management unit may
be corrupted and a reset of the PMU may be needed.
So many choices; but to find the right one, this time!
Good luck & happy computing!
PS: is your Discussions experience particularly slow today?

i have a macbook 2011 and its booting to the apple with a loading bar. it gets halfway and changes to a screen with the apple and a spinning circle. It spins untill it dies. will not boot to safe mode. Do not have orriginal osx disk either.... HELP
It happened after an update

I upgraded the ram and hdd a while back(RAM first with no issues, then hdd around 2 months later). The computer started freezing a few days after the hdd upgrade.
I reformatted the hdd and it worked fine for a few weeks then same freezing issue. Instead of wiping the drive again I repaired the disc and this had it fixed for about a month. I was booting in safe mode for a few days with no issue and went about uninstalling 3rd party apps. Then the Kernal panic issue started, When I inserted the OS cd the screen went blank and has not come back on after repeated boots.
Can we put this down to logic board and if so can it be repaired rather than replaced?
Thanksthanks for the reply,
just reinstalled the factory RAM and HDD. Same issue of blank screen. At the moment i have no way of connecting to external monitor.
The OS cd is still in drive and i can hear the drive spinning for a few seconds at the start but it stops after about 20 seconds. -
HT201262 Will not boot into safe mode
Hello,
My MacBook pro 2012 crashed last night. Could not force quite so closed it down. On restart it would get halfway then stop. I have japped p-ram (I know it is my called this anymore) but then loads halfway and the turns off. I booted into disk repair and it found a couple of problems so repaired successfully. On restart it still gets halfway then turns off.
From reading the apple support it seems other people have the same problem. All mention booting into safe mode. For the life of me I cannot get my machine to boot into safe mode!
I do exactly like the instructions say but it always just goes to the page where I choose whether to log in as me or a guest.
What am I doing wrong?!
I am on a MacBook pro running Yosemite.
Many thanks for any help.

Can not boot in safe mode or from install disk
Having major issues. MBP getting stuck at a blue screen after the gray apple screen. Tried pressing and holding shift key while starting for safe mode and still goes to blue screen. Tried holding c key and starting with sl install disk in drive and still goes to blue screen. Issue started with continous cycle back to login screen from my main user account and due to my stupidity of turning on automatic login from a admin test account (thinking I could trick it), I am now in this vicious cycle.
And no I don't have a bootable clone. I just updated to SL and like an lazy idiot didn't go ahead and make my bootable clone.
FYI I do have a timecapsule with a week old or so backup.
Any suggestions?having a time capsule with TM backups is certainly good. you can always restore your system from it in a pinch.
do you have a firmware password set perhaps? it would preclude booting in safe mode or from the dvd using "c". reboot and hold option at the chime. this should boot you into startup disk manager where you can choose to boot from the DVD.
if you do have a firmware password set it will ask you to enter the firmware password before letting you use the startup disk manager. -
Macbook will not boot in safe mode
I tried to install the new Maverick OS X software but it is telling me that the install failed because the disk Macintosh HD is damaged and can't be repaired. I tried to restart my mac in safe mood so I can back up my important documents but the gear just keeps spinning. Can someone please help me!!!
Which model MacBook Pro do you have? Have you tried booting into your Recovery partition (holding down the command and R keys whilst booting)? If your MBP supporst it, have you tried Internet recovery (holding down the command, option and R keys whilst booting)?
Call back,

Can someone please help me with a Macbook Pro booting question?
Recently, my mid 2010 MacBook Pro has started acting up when I am on Safari. Safari would unexpectedly crash multiple times in a row, then run fine for a while, then again, crash repeatedly. Not long after this began happening, an error message from my Prosoft Drive Genius 3 software, threw out a message that a serious error had occurred and I needed to repair the HD volume. Before I was able to run the software to repair the HD volume, the machine stopped working. I turned off the Macbook and when I tried to restart, it would not boot. I have since removed all external hardware from my machine and tried several times, unsuccessfully, to boot. I have also tried booting in safe mode when also does not work.
Any suggestions? Thanks for your help.Try SMC reset:
Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.
On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time. (four keys together)
Release all the keys and the power button at the same time.
Press the power button to turn on the computer. -
Windows Installer not installed properly, then boots to safe mode w/no backlight?
I have only used my laptop for about 2 weeks.
I tried to download an Adobe Reader update, and I got a message that said "Windows Installer was not installed correctly."
I retarted my computer, but it would only boot in safe mode.
I tried a System Restore, but I got a message that said "System Restore doesn't appear to be functioning properly."
I tried to do a virus scan (just in case), but my computer will not connect to the internet, so that's not working, either.
I tried to restart once more, but as soon as I went to put my password in, the backlight on the laptop would shut off, and then it would only boot in safe mode.
I put the laptop away for a little while because my life got very busy and I didn't have the time to deal with it. Today, when I turned the laptop on to try and troubleshoot, it booted normally, and successfully- no safe mode, backlight still on- and then it told me that System Restore had worked.
What gives?
Anyone have any ideas what happened / what I did to make this happen / how I can avoid it in the future / if the computer is actually going to function properly or if it needs to be sent back?
Thanks!Hello SuperNova and welcome to community,
When you restore the system earlier to back date it did not get complete and also Windows 7 has startup repair option which fixes the common startup bugs.
Best Regards,
Tanuj

Mac Pro won't boot up, not even in safe mode.
Problem: Mac Pro having severe lag issues. Added more ram, removed Kona3, etc., nothing. Tried repairing with disc warrior but unable to repair startup disc unless booted from disc warrior disc. Won't boot up from disc warrior disc so set startup disc to the disc warrior disc. Now comp won't boot up, not even from safe mode. Any suggestions?
Boot from your OS X install DVD.
You always need to have a 2nd backup you can boot from, or an emergency (only) boot drive.
Disk Warrior does not have 10.5.2+.
If you can't do anything, zap pram, see if that helps. Or pull your drives and boot from your DVD. Setup OS X on a FW drive.
And of course, always always have at least two backup sets of your system; and sets of your data - so one set at least is always off line.

Why won't my g4 desktop come on. I was trying to boot in safe mode and it would not go in safe mode. It won't come back on anymore. Can some tell me what to do.
Try Single User mode (Command+S while starting up).
Then, run fsck.
At the command-line prompt type:
/sbin/fsck -fy
Press Return. fsck will go through five "phases" and then return information about your disk's use and fragmentation. Once it finishes, it'll display this message if no issue is found:
** The volume (name_of_volume) appears to be OKIf fsck found issues and has altered, repaired, or fixed anything, it will display this message:
***** FILE SYSTEM WAS MODIFIED *****
Important: If this message appears, repeat the fsck command you typed in step 2 until fsck tells you that your volume appears to be OK (first-pass repairs may uncover additional issues, so this is a normal thing to do).
When fsck reports that your volume is OK, typerebootat the prompt and then press Return.
Your computer should start up normally and allow you to log in.

My Power Mac G5 will not fully boot without safe mode, it only comes to a blue screen where my cursor duplicates in to 2, (one is frozen, one can move by moving the mouse). What is my problem, and how do I fix it?
Great clue Lukas...
One way to test is to Safe Boot from the HD, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, Test for problem in Safe Mode...
PS. Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive
Reboot, test again.
If it only does it in Regular Boot, then it could be some hardware problem like Video card, (Quartz is turned off in Safe Mode), or Airport, or some USB or Firewire device, or 3rd party add-on, Check System Preferences>Accounts>Login Items window to see if it or something relevant is listed.
Check the System Preferences>Other Row, for 3rd party Pref Panes.
Also look in these if they exist, some are invisible...

HELP! iMac G5 hangs at blue screen, but boots in Safe Mode
Please can anyone guide me to recover my iMac G5 PowerMac 8,2 running OS X 10.4.11.
Problem; Mac hangs on start-up at blue screen after grey Apple screen. Mouse pointer eventually appears but that is all.
Actions taken so far without success:
1. Disconnected the printer and rebooted - no success.
2. Booted in Safe Mode - first time the screen was completely scrambled but with safe mode log on screen showing through.
2.1 Rebooted in Safe Mode OK This has not occurred again and I have entered Safe Mode twice more without problems. But worrying!
2.2 In Safe Mode I ran disk Utility and verified and repaired Permissions, mostly old EpsonPrinter files.
2.3 I also verified the Disk, which was reported OK.
2.4 I was able to save critical documents to USB............ Phew!
2.5 Reboot in Normal Mode - no success
3. Reset PRAM
3.1 Reboot in Normal Mode - no success
4. Reboot in Safe mode - works fine. NOTE: time and date appear to be correct and dont need resetting.
4.1 Run Disk Utility again and Verify Permissions - OK. Nothing needed fixing.
4.2 Run Disk Verify - Passed OK
4.3 Reboot in Normal Mode - no success. Hangs at blue screen with mouse pointer visible and working. Then pointer vanishes.
I would be most grateful for your help in moving this forwardGot to figure out which which of the things dropped when you boot in safe mode is causing the problem.

It's a MBP mid 2010. Last year it had some problems and an Apple authorised shop changed the HD and upgraded the OS from Snow Leopard to Lion. After that it seemed fine. Recently it started getting very slow and apps (e.g. Chrome, Flash) would crash. At some point it seemed stuck so I gave it a hard shutdown - bad idea. After that it would only boot in Safe Mode. I ran repar disk and repair permissions from the Disk Utility and it booted normally again but extremely slow. I upgraded to OS X 10.8.2, but didn't solve it. I tried booting with Command D to have a hardware diagnostic - it wouldn't boot and now it only boots in Safe Mode.
All data is backed and I have an external HD (but not an OS X Disc). Ready to anything. Help please!

Also you can perform #1 and #2 as these occur before Safe Mode, so you just reboot again with Shift key if you need to enter Safe Mode again.
At this point it sounds like your hard drive is dying or some sort of other hardware issue which I can only advise this.
Try to install OS X on a external drive and boot from it, if it's fine then you know your internal boot drive is dying.
Create a data recovery/undelete external boot drive
You can replace your internal drive yourself.
OtherWorld Computing is pretty good about providing drives and tool kits to perform that function yourself.

MacBook Pro (Mid 2010) will only boot in safe mode.
I've been unable to boot my MacBook Pro normally. It will boot in safe mode, and, until today, I was able to get a normal startup after resetting both PRAM and SMC. Running "Repair Disk" on the startup disk did not reveal any problems. I have also done a recovery boot to reinstall OS (10.9.1), which did not help either, though I did not wipe the hard disc first (I did back it up).
Had to take it to Apple back in January when the screen started acting funny, i.e. getting static-y and going blank for seconds at a time but then coming back. Their tests showed that there were no hardware problems, and the screen issue was eventually resolved by doing a PRAM reset. About 14 months ago, I had the logic board replaced.
Also, I'm not sure if this is related, but when I have been able to boot normally, if I quit Google Chrome, the machine will freeze completely.

Any ideas are much appreciated!First try doing a Software Update.
Then restart and see if that works.
If not then I would update Java.
Restart and see if that works.
If not then delete the following plist items.
[invalid] com.oracle.java.Helper-Tool.plist
[invalid] com.oracle.java.Java-Updater.plist
Should find these in:
/Macintosh HD/Library/LaunchAgents
/Macintosh HD/Library/LaunchDaemons
Now restart & see if that works.
If that doesn't work try deleting everything in:
/Macintosh HD/Library/StartupItems
Hope this helps.
