Osx won't boot

Hi there. I'm new here and after googling around I thought it'd be best to ask here. I attempted to use a Fedora Core 6 live cd on my mini. To have it boot up from the CD I used the Startup Utility to select it and rebooted. After ejecting the CD (holding down left mouse button) and rebooting OSX will no longer boot, all I get is a blinking cursor. I suspect it is looking to boot off of the cd/dvd drive. It should be noted that I am using a Logitech wireless keyboard/mouse combo ( I don't know if that is an issue or not.

Insert your OSX system DVD. Start up while holding down the C key.
Once booted off the DVD go to Apple/system preferences/start up disk.
After you click on the HD icon select your HD as the start up disk.
Reboot.

Mac OSx won't boot up after update to 10.6.7?

Mac OSx won't boot up after update to 10.6.7?

Hi Mike
This is called a kernel panic, similar to s 'blue screen of death' on Windows. When you say you reinstalled 3 times, do you mean the OS or the Update?
When does this kernel panic appear? You may have a hardware issue if it's happening on boot.

OSX won't boot completely

When my MBP boots it stays at the following state:
The mouse works, the keyboard works, i can change the volume and brightness.
But it won't continue to the desktop, it should auto-login.
Before this happend i've shutdown my MBP by holding the powerbutton for 5 seconds.
Because none of the applications responded and the menubar didn't respond.
I've tried removing preferences & caches of the user. plist files for the loginitems,desktop & windowserver.
I've tried repairing the disk, it was ok, I fixed te permissions.

Reinstalling Mavericks, Lion/Mountain Lion 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.
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. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU 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 DU and return to the main menu.
Reinstall Lion/Mountain Lion, Mavericks: Select Reinstall Lion/Mountain Lion, Mavericks 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.

HELP! OSX won't boot?

OSX 10.4
Macbook Intel 2.0Ghz
I am running boot camp w/ xp on a partition of the HD
I downloaded/installed all the updates that were available. Allowed the computer to restart itself. Now when i try to boot to OSX it shows a folder with a question mark on it. Then it boots to windows instead.
Please help, i have a paper to finish for school by tomorrow and the other 32 pages are on the Apple part of the HD.
Thanks,
Rob

Hi Rob,
first of all: WELCOME TO THE DISCUSSIONS!
Did you Repair permissions before and after the update?
Insert the install DVD and reboot while holding down the c-key. Once the installer has started and you selected your language, select "Disk Utility" from the MENU. Repair the hard disk and repair permissions. Quit disk utility and reboot. Does the problem persist?

OSX won't boot up

Hey all,
I'm hoping someone can help me with my MacBook Pro. My wife was running Power Point on it for a few hours yesterday and ever since then, I can't get it to boot in OSX. It just hangs on the grey screen and keeps spinning. I've tried the following:
Reset PRAM
Reset SMC
Ran Repair Disk (disk shows up okay)
Ran Repair Permissions (this always fails)
Tried to start in safe mode (doesn't work)
I did safe mode with a status and I get the following errors: Vnode_validate_compressed_file_type4 error: -1 and Disk0s2: I/O error.
I tried reinstalling Snow Leopard, but it fails
Not sure what else to do. I have Windows XP on here and that loads fine. The closest Apple Store is like 70 miles away and i would rather not make the trip. I can start it up as an external drive via FireWire and everything appears to be fine. Of course I haven't done a backup recently and I don't want to wipe it. Anyone have any ideas?
Thanks,
Jeff

Hi Jeff
I have fixed a similar problems in the past, most of them seem to happen when running Microsoft Office on a Mac. I have to agree with Linc, it is time to replace the hard drive, you can never trust it anymore. However, problems with bootloaders have the advantage, that if you don't have a recent backup, you can still easily get to your data on the hard disk for free.
You might have already solved your problem by now, but just in case there are others out there experiencing the problem.
First of all you need to start with the Laptop in the power down state. Hold the power button down until it goes silent.
Press and hold the 'alt' key and turn the power back on. Hold the 'alt' key down until you get the 'Macintosh HD' and a 'Recovery HD' icon. If you have an OS X installation disc in the optical drive, you will also have an icon for this as well, but it will not help you, so ignore it. Just as a side comment, the 'alt' key is often referred to as the 'option' key. There are many postings on this, but to those of you who make rude comments when somebody asks this question, not all keyboards are the same!
Getting back to more important things, select the 'Recovery HD' using the arrow keys and hit enter. The laptop will now boot from the recovery image.
When you get the application 'Mac OS X ....' then you have the choice to restore from the latest backup on the time capsule. The '...' will be different, depending on the standard language' You can change this in the dropdown menu, if you are more comfortable working in a different language to the one given.
Assuming you don't have a recent backup, then you need to go through the drop down menu items until you find one called 'Terminal'. Start the application and make the window bigger.
For the next step, I am going to assume two things. You have an external hard drive, which is bigger that the amount of data you want to recover connected to the usb port. You are not afraid to type in a few unix command. If you feel uncomfortable, then ask some IT colleagues for help.
First of all, you will need to use the 'cd' command. This enables you to change directory. Type in 'cd /Volumes' and hit enter.
Next you will need to see what's in this directory, so you will need to use the second important unix command, namely 'ls'. Type in 'ls' and hit enter.
What you get on the screen are different volumes. You will see the 'Macintosh HD' volume where your will find all your data and the external hard drive connected to the usb port. Obviously, this will show up depending on the label that you or the manufacturer gave it.
You now need to navigate to the directoy where all your files are stored. to do this type in 'cd Macintosh HD/Users' and press enter. One tip here, press the tab button and it will autofill the rest of the text for you, so just keep typing until the volume name is unique.
In the Users directory, you will need to do another directory listing. Type in 'ls' and you will get two folders, namely 'Shared' and the folder where all your data is stored. You can either stop here, or navigate into your personal directory, depending on how much you want to recover.
The next and final command is to copy the files across to the external hard drive, e.g.
cp -R -vp text1 /Volumes/text2
where text1 is the name of folder where your data is stored.
text2 is the label of the external hard drive.
The '-R' is important for copying all sub-folders and files. The '-v' is important to make it verbose. This will give you confidence that the computer is doing something, as copying 750 GBytes will take several hours.
When the computer has finished copying the files, you will get the '-bash-3.2#' and the cursor, or something similar.
That's it, now you can close the terminal and restore from the latest backup on your time capsule. When your computer is up and running again, you can copy as many of the files as you need across from the external hard drive using the trusted drag and drop.
Hope this helps.
Cheers

Changed MByte to GByte. Sorry, I started when computers were fitted with 1 KByte.

Windows and OSX won't boot after partitioning

Hi so I have a 2012 MacBook pro, it is running mountain lion and I also boot camped it and installed windows 7. I partitioned the hard drives correctly and it has been running great. Today I was on windows and used the disk manager to shrink my windows partition so that I could create another seperate 5gb partition for school. After I did this, my computer was running fine until I restarted it. When the windows logo appears while booting, it freezes and it flashes a blue screen and then shuts down. When I hold down the option key to boot into Mac OSX, the only option that comes up is windows, not even my recovery disk.
How do I fix this? I need to boot into these because all of my school things are on these drives. Please help

Never in my reply did I say I don't use Boot Camp or not to use boot camp. But I don't. And I don't have Windows installed in its own partition. I use a VM for Windows on my Mac for the few Windows programs I run on the Mac.
I started to read that reply but then didn't finish it as that poster was talking about Win 8 and AFAIK right now neither Boot Camp or the driver package supplied by Apple for Windows supports Win 8. Even though it isn't much different then Win 7.
It does create a Separate partition, as does Win 7, that is a hidden partition, just like Win 7 does, but it is different in some ways from Win 7. So that may of been the original problem that poster was having.
In any event I don't think that post will help the OP of this thread. But I may be wrong. Only time will tell.
The big reasons I don't use Boot Camp is I can't stand Dual Boot system and that I can't Re-Partition the BC partition without screwing the whole system up. Tried it, didn't care for it, then removed it and went VM.

Mac OSx won't boot up

After a minute of that loading circle under the apple symbol in the middle of the screen, the apple symbol turns into a no entry sign, which I've never seen before. I know there's a button to hold down when you switch the computer on that can take me to a different screen and I can run some repairs, but I forgot what it is, any enlightenment would be great

Hi Divus! and Welcome To Discussions!
Is this the No Entry Sign you are seeing?
What was the situation before this problem arose?
Did you make any changes to your system?
Exactly which model Mac do you have?
What OS are you running?
What size is your Hard Drive, and how much space is available?
How much RAM is installed, and is it original or added?

MacPro, OSX 10.7.4 Safari 5.1.7 won't boot keeps crashing. How do I install another version? It won't let me.

In my Applications folder, I have Safari 5.1.6. When I try the manual install of of 5.1.7 it won't let me because it says I have a "newer" version of Safari already installed! ???
I tried reinstalling OSX 10.7.4, but still have the same problem. You can't throw it out or replace it either, or restore from Time Machine.
Here's part of the crash report explaining why it won't boot...

B&W G3 won't boot OSX Panther

I have rev2 B&W G3/450, 640 mb RAM, 2 video cards (ATI Rage128 and ATY RV100) each connected to a Sony TFT display, and 2 scsi cards. The computer has the newest firmware. ATA drive has OS 9.2 which works fine. I want to be able use Panther on that computer. The problem: it won't boot into OSX Panther, be it a scsi drive or install CD. I have installed (commercial black CDs) OSX on a G4 and the system works fine on that computer. It fails when using same hard disk as startup on G3: the system starts booting, shows gray apple logo (on display connected to ATY RV100), then after a long pause it displays the "nogo" sign (crossed circle). When booting from CD, it just runs the circle forever. I tried OSX installer CD as well as DiskWarrior CD with the same result. IS there any trick to get it booting into OSX? Theoretically, it should work.

@Thomas: good shot -- the problem is scsi related but not as simple as card compatibility
@Ali: as I said, firmware is uptodate. Rev2 has NewWold ROM so KB Article you refer to does not apply.
I spent a few hours fiddling with hardware, starting by installing the card I used in G4 to install OSX. It worked just fine in G3, so I rebuilt original configuration step by step. To make the story short, I have 2 SCSI drives and 1 ATA drive. If both SCSI drives are on the same bus, the boot hangs. If I put them on two different buses, OSX boots fine. At first glance it looks like SCSI ID conflict but it ain't -- each drive has a unique ID. Also, G3 boots fine into OS9 with both drives on the same bus. The OSX boot hangs also if I put a SCSI scanner on a bus with a hard drive, but works fine if I put it on another bus. No such problems under OS9. So, it seems that each SCSI bus can handle only one physical device under OSX.

And I lost my OSX DVD is there any way to fix this? I just did a software update yesterday and have about 20GB left on my Hard drive. The last thing I did was try to install some plugin's for Pro Tools 8, but it wouldnt let me install so I restarted and now I'm screwed. Please Help!

You have to consider the possibility the hard drive may be dying. If your data isn't backed up, try one of the tools below:

Once you are sure your data is backed up, we can examine other possibilities. In the meantime call AppleCare for your original installation DVDs. You may need them.

Macbook Pro won't boot OSX after Yosemite upgrade 10.10.3

I downloaded the update to 10.10.3 this morning before driving my daughter to daycare. When I came back, my Macbook Pro had rebooted into Windows 7 (Boot Camp). I restarted it by telling it to reboot to OSX, but it boots Windows again. If I turn it off completely, and then turn it on again, there's no chime... just a black screen for about 30 seconds, followed by "Starting Windows". I'm about to reboot to try resetting NVRAM and SMC, but I don't know if that's going to work without the chime...
I really need OSX to get going, so any help appreciated.

If you don't already have a current backup, back up all data, then reinstall the OS.* You don't need to erase the startup volume, and you won't need the backup unless something goes wrong. If the system was upgraded from an older version of OS X, you may need the Apple ID and password you used.
There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
If you installed the Java runtime distributed by Apple and still need it, you'll have to reinstall it. The same goes for Xcode. All other data will be preserved.
*The linked support article refers to OS X 10.10 ("Yosemite"), but the procedure is the same for OS X 10.7 ("Lion") and later.

Mac won't boot after updating to OSX 10.6.4

I am on my 3rd Mac that won't boot after updating to OSX 10.6.4. One MacBook Pro and two iMacs. I fixed one but the last two are getting the better of me. HD is not fried. Have tried every keyboard shortcut on startup, Disk Warrior via. Target Disk, repairing permissions in single user mode. The machines will not boot off of a CD or DVD and it will not boot up in safe mode. Something in the startup files is preventing startup. I am suspecting Sophos antivirus. I tried to uninstall it and trash it but I think it's still blocking something. Any help would be appreciated.

Got it! Not sure if removing Sophos had anything to do with it but here's what I did.
1) boot dead machine in Target Disk Mode (iMac)
2) boot good machine off Snow Leopard disk (MacBook)
3) install OS to dead machine- I found this next part very curious. When the install was complete the MacBook restarted as the iMac.
4) ran software updates
5) shut down MacBook then shut down iMac
6) rebooted iMac- all was good
I actually did this twice because a co-worker had the exact same problem on her MacBook Pro. Got both fixed today.
Thanks everyone for your help!

IBook G4 suddenly won't boot past the "booting OSX" screen.

My iBook G4 suddenly died and now won't boot past the "Starting OSX" screen. The blue bar goes all the way across but never moves to the next screen. I have my original disks, containing OS 10.4.5. I am trying to boot from the disk, but just keep getting the Installer program. When I try to choose a startup disk, it still won't start. Any help or ideas? This is urgent.
BTW, I am a photographer and was workig in PhotoShop7 -- a program I use all day, every day.

Start from the install disc again and choose Disk Utility from the menu. Highlight the drive on the left and click Repair Disk. If it reports errors and repairs made, repeat the process until no errors are reported.

OSX Mavericks won't boot after changing user home folder

Hi guys,
I have a clean install of Mavericks on my macbook pro 17" and have two drives in. One is hdd (in place of superdrive) and the other is ssd where OSX is installed.
I have uset the following:
If you right-click on the User in the Users & Groups system preferences, choose "Advanced Options..."
You can then change the location of the home folder
to change location of my user home folder and set it up to be on the hdd but now OSX Mavericks won't boot. I get the progress bar on boot and it just freezes no matter how long I left it.
Can anyone help me out?
Thanks!

I managed to boot after dozen tries and restored the location of the home folder to where it was at the first place.
The thing is, on my second drive I have the whole user folder with data, settings and everything else in it and would really like to use it in the Mavericks.
I guess I could just copy it over the one in the Mavericks and it should be good?
Not sure, why this is the issue now since on previous OSX releases this home folder changing thing worked without problems :/
If anyone else have the solution for this problem please do feel free to let me know!
Thanks!
