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.
View 2 RepliesOccasionally, this iMac starts, and it will say "safe boot" in the login screen, and I have not done anything to make it do that. I do not have a sticky shift key, as far as I can tell.

I was troubleshooting an issue my brother was having with his Macbook over downloading files, installed Firefox for him, ran Apple updates and while the updates were installing the computer froze. He restarted it, and on startup he got a circle with a slash through it. I've been googling and checking forums and I tried booting into safe mode (Shift at startup, I believe?), and putting in the OS X disc that came with it and booting from that (C at startup?) but I get nothing. It just goes from the Apple with the loading circle, to the picture of the slash circle. I'm not really sure on the specs of the computer or the OS version, as I'm rarely on it.
View 2 Replies View RelatedWe have an older model G5 Dual (no Intel Core) at the office that we tried to install CS3 on. I told them that first we would need to upgrade from 10.3.8 to 10.4.10, which they did, and then installed CS3. But they did it without running the disk utility repair permissions after the OS software installation, as I have routinely done with my Mac Mini at home, after the horror I experienced with the 10.4.9 upgrade. For a couple of days, the computer ran fine, but I noticed an increase in the fan spinning up yesterday afternoon, then quirky keyboard things -- like I'd select an item with point and click, and it would highlight everything else near it, I'd go to quit an application and it would ask if I wanted to quit all applications.
After backing up my current InDesign work files on a flash drive (but not the whole darn art folder), I rebooted and it came up in Safe Boot mode 6 times without holding any key down. Attempts to boot from disk have failed, even with holding down the "C" key. It's also not allowing us to type out full passwords at the log-in screen... you start typing and after you hit four digits, it clears, then only allows two digits. How we can:
1.) Force boot from disk, and,
2.) Hopefully fix with disk utility whatever wonkiness is occurring?

I've been trying to partition my drives and install Windows on my late 2012 imac. I last adjusted my partitions using disk utility and now receive the prohibitory sign on start-up and cannot boot up in safe mode; pram reset; type commands in single user mode. Running on Mavericks OS.

Alright I was going to load Windows on a partition thru Boot Camp. However I decided not to and then used the Boot Camp assistant to remove the Windows partition.
Ever since I got rid of the Windows partition, I've have to hold the OPTION key just to get my MBP to boot even though there is NO other operating system installed on the old partition. If I don't hold the OPTION key it won't boot, it just goes to a black screen.
I'm new to mac's and don't know what to do.
So I bought a "new" PowerMac G4. I have two already.
The guy said it was running os 9 but now it wouldn't boot. I figured it needed an OS and the guy was wrong. I try to boot it up...
flashing ? folder
So I go thru all hell trying to install os x and what not.
It won't boot to the install CD. I finally got it to boot from my other Powermac's HD with OS X on it, but I can't seem to install OS X on this other HD, but that's not really what I'm asking here...
When I startup the PM and hold Option, nothing happens with either HD installed!!! No boot menu comes up.
Also when I hold down C, nothing happens at least nothing different. It doesn't boot to the CD.
Why is this?
Sometimes it seems to boot to my HD OS X and sometimes it boots to the CD on it's own. I can't choose what I want it to boot to unless I start the OS X and select it from there.

Drive isn't showing up when booting mac book. How to fix this?
Info:

I have a MacBook 4,1 with Intel Core 2 Duo processor 4GB Ram. It is taking over 10 minutes to boot up past the gray apple screen when I turn it on. First I cleared the PRam (?) then I checked the disk using Disk Utility Verify, and it said the disk needed repairs. So I ran the disk repair and it said it was unable to fix the errors on the HD. Â
I did a little research and tried booting into the Single User mode, then running /sbin/fsck -fy. It said that it found errors but could not fix them. I ran it two more times as suggested and got the same result each time. I then tried rebooting and now instead of taking 10 minutes to boot up, it takes about 5 minutes on the gray apple screen and then just turns off. I started in Verbose mode to try to troubleshoot the error and it appears the last thing to come across the screen before power down is a message "Apple Yukon 2: RxRingSize <= 1024....etc".Â
I decided next I would run the Apple Hardware Tester. The test came back with an error code "4SNS/1/40000001:IG0C-0.265". I am very good at searching the web but I could not find any errors that had the IG0C or IGOC or any combination at the end, but plenty of 4SNS/1/40000000(1) errors with different endings. From what I can tell people are saying anything with 4SNS/1/4000000 is a logic board failure, but this computer was literally just booting this morning until I did the /sbin/fsck -fy.Â

I verified the hard disc on my mid 2010 3.06 ghz 10.7.3 iMac this morning to be greeted by a box telling me this disc was corrupt and that I needed to restart while holding cmd+r until the apple logo appears then to repair the disc.at this point I would like to say that I am posting this from said iMac and it boots up normally and runs fine.but,when I start it holding cmd and 'r' let go at the apple logo the cog starts turning below the apple for about 10/15 seconds then the apple is replaced with a circle with a line through it (the cog keeps on spinning below it) it seems like it would just sit like this for ever - after about 5 mins I held the power button, turned it off, turned it back on again and just left it to boot up normally - no problems. thought I would try it again - turned it off, held cmd and r exactly the same as before......Â

My best guess is the problem is not specifically hard-drive related since all the 'normal' fixes just won't work. The only way i've managed to keep the Macbook Pro on for longer than a minute is through target drive, where it seems to work just fine - i can access everything. To sum up everything:Â
1 - I tried resetting the PRAM
2 - I tried to go in to safe mode, it shut off before i could type the password
3 - I tried fsck -fy command from single user mode, sometimes i can get to actually typing it but mostly it shuts off before
4 - I tried to repair disk via target drive - success, no problems detected
5 - I reinstalled OS Mavericks.Â
The Macbook Pro previously had some problems with the power-button not working properly (a mac-cunning friend of mine had to open up the mac and start it by swiping to metal pins on a specific (battery/power?) part inside it.

My macbook (early 2008 model). Looks like my disk drive isn't working correctly; I put in a new hard drive. I went to reinstall Snow Leopard then upgrade to Lion. Ever since then my mac only seems to work in safe mode. I used my imac to load snow leopard (with firewire); and downloaded lion from app store. Is there a way to wipe clean and start over? There is nothing on the computer that I need. I keep all my important files on an external hard drive. My big concern is I don't know how to do it and second since I don't have a disk for lion will just going back to app store allow me to re-download or will I have to pay 30 bucks again.

As of yesterday my Mac book pro will not start up. It will not go past the gray screen with the apple and spinning timer indicator. When I try and start up holding shift to enter safe mode it will not start up either. I have tried turning It on and off many times. I am not sure what to do or what the problem might be. Running OS 10.7.
View 3 Replies View RelatedMY MBP is giving me the "NOT" sign on start-up. This comes after initially displaying the Apple logo. This MBP had a new logic board installed by Apple just two weeks ago -- and I know I can take it back but I'd like to fix this myself. I put in a different hard drive after getting the MBP back. It has worked fine for several days. Don't know if these points are relevant, but:
1. First thing I noticed today is that neither of the USB ports would read a flash drive. The port would, however, work mouse and keyboard.
2. The initial non-boot episode took place when I had external hard drives daisy-chained in via Firewire. But, again, this had worked previously, as recent as this morning.This may be significant:
3. The last tasks performed on the MBP were -- for the first time -- to edit video in FCE, make DVD in iDVD, burn IMG file.
4.I have connect this MBP as a target FW drive to another MBP and run "disk verify" and "disk repair" in Disk Utility. It says the drive and permissions are okay.
5. I have booted to a copy of Disk Warrior (latest version, version 4, I believe) and rebuilt directories and files along with verify/repair permissions (everything DW will do). And when re-starting, it still won't boot.
6. When I boot off Snow Leopard DVD and run Disk Utility¦"verify disk" says "the volume appears to be ok¦.when I "repair disk" it reports "Volume repair complete." and "Updating boot partitions for the volume as required."
7. I'm able to boot in SAFE MODE, but when I try to restart in normal mode, it won't boot (so nothing was automatically fixed)What can I do in safe mode to address my problem?

I've used the bootcamp assistant to create a 200 GB partition for Windows. I installled windows 7 x64 on this partition, everything is going well so far. I'm able to press the option key after installation and run windows and perform some updates (note, I couldn't install the required software IN windows from the snow leopard disk, let's hope this is not the source of my problem).
Everything went well so I booted back to OSX and I noticed that I needed some more partitions, so I've split my Macintosh HD further into a Media and a School partition. I didn't touch the windows partition though.
After experiencing (before) with hackintosh computers I know that i have to rewrite the boot configuration of the harddrive. Because now I'm not seeing the Windows HD anymore while holding the option key at startup and therefore unable to boot into Windows anymore. Even parallels can't discover the Windows partition.
I've tried repairing permissions, and nothing. I've tried to use the repair option on the Windows 7 disk which states it can't be done.
What can I do? Do I have to repartition it again in an different order (bootcamp states that it can only create a Windows partition if there's only 1 partition in the harddrive, so it's logical to repartition the drive after bootcamp created the Windows HD or even after the installation of Windows itself). Perhaps I need to rewrite the boot config of the mac, which I don't have a clue about.
Being 64 bit windows is not an issue, because it worked at first (before repartitioning)
