Mac isn't starting up normal?
you must have removed the unix shell program /bin/sh or destroyed it or the directory that contained it. you need to re-install os x. or get the files back from backups. update: to re-install , you power down, insert the dvd (or cd), reboot while holding C. if that doesn't work you are far worse off than anyone imagined. the key is holding down the "C" key while rebooting to force the mac to use the CD (or dvd) SECOND UPDATE! disk warrrior won't recreate /bin/sh! you need to re-install os x!

My 15" MacBook Pro (2010) will not boot past a grey screen with Apple logo. There is no startup tone. Progress bar appears and disappears but the progress wheel keeps spinning for hours. Any suggestions?
Apart the possibility of a hard drive failure, that you can check by running Apple hardware test (by pressing D at boot-up), you can start your Mac in Recovery Mode by pressing down CMD and R at boot-up. After a grey screen with a keyboard and a mouse symbol, you'll access Disk Utility and you'll be allowed to restore your MacOs from a Time Machine backup, from the Recovery Partition or from DVD (if you have a bootable DVD or Snow Leopard DVD Install). Hope this will help.
How do you boot to a diffrent OS on a mac?
When I hold down alt all it gives me is a pic of my hard drive, saying the name of it. If I click the little circle thingy (Refresh?) It just makes my cursor turn into a little clock thing, then go back to what it was before, if I click the arrow on the right, it just goes to the message I was talking about. Oh, and if you have to be so pro to use a mac why do they say how easy it is? ^^
My Macbook Pro Won't Boot Up- Horizontal Lines all over screen!!!!!!!!!?
I purchased my macbook pro december of 2011 and unfortunately did not puchase apple care with it, and have been using it fine until about 1 month ago when it started to crash multiple times a day. After awhile it even started booting up with horizontal lines on the screen with the apple logo and that was usually the indicator that it wasn't going to boot into the login screen. It was on and off between being able to boot in or not for about 2 weeks. I even thought that it was because of the laptop fan I was using but after buying a new one we concluded that it was probably because of a hardware problem. Since late last week it has not been able to login, so its basically been sitting in my room "bricked". The worst thing is that I didn't even backup the hard drive yet! I have tryed everything! What I tryed include the following: Pressing the Shift button to go into safe mode(fail) Holding control option p and r(fail) Resetting the memory cards(fail) Control R(fail) Going to get it fixed would probably cost just to get it diagnosed, and since we don't have an apple store nearby, their are only apple authorised providers which aren't hardly has great. If you've had the same problem please tell me how you fixed yours!
How can I install Windows 7 on a Mac Pro without OS X or Bootcamp?
Do you mean you want only a single partition with Windows on it? You can do that, but you'll need to use Boot Camp to create that partition, and to create a flash drive with Windows drivers for the Mac hardware.You can then delete the Mac partition, resize the Windows partition to fill the disk, and install Windows. After Windows is installed, you'll need to install the drivers from the driver install disk that Boot Camp helped you create.If you then want to uninstall the Boot Camp control panel, you can.If you mean that you want to somehow get Window installed without ever booting up into OS X even once, then it's going to be a lot harder. You'll have to find some way to overcome Windows lack of support for booting in an EFI environment. And you'll be stuck with some generic drivers that can't support all the features of the hardware (like the multitouch trackpad).It might help to improve the quality of the answers you receive if you could explain why in the world you would want to do this?
My MacBook won't boot, but I get a flashing folder with a question mark—what does this mean?
What you are describing is the way the Macintosh BIOS tells the user there is no OS installation detected on the connected drives. It means that either your OS is uninstalled or corrupted… or more likely, your hard drive has crashed. (It could also be disconnected, but that is unlikely if you haven’t been working on the internals of the computers)If you do not have professional expertise with Macintosh hardware issues, you should consult someone who does to help with this issue; I’ve done this before myself, and there are plenty of opportunities to mess things up worse than they already are. If your data is still available, it needs to be recovered using a working Mac that can access and copy the data. (If the issue with the drive is the OS installation, your data should be fine… if the drive has failed entirely, your data may be gone and unrecoverable)If the issue is your OS installation, macOS can be reinstalled by using the Recovery Partition or, if that is also corrupt, by tethering your Mac to a working one using Target Disk Mode. If the issue is the hard drive itself, it will need to be replaced by an Apple Authorized Service Professional.
MacBook Pro - System bootstrapper has crashed?
Time Capsule would have been great. How did you manage to ignore it? Reinstall does not remove any files at all. Only Disk Utility can erase everything. All the old files are in a folder called "Previous Systems". You can drag files out of there to add to the new system, but don't move any files from the "System" directory. Stick to the Users files, Applications, and Library. Even then, be careful about the root Library. You are always better off reinstalling apps than trying to drag their bits and pieces to the new system directories. Do this before you start moving stuff... -- Use Software update to get the new system fully updated. -- Install anything you can easily do right away. -- Connect an ext. HDD that has Mac format and as much available space as the used data on the startup volume. -- Open Disk Utility. -- Select anything at left. -- Select the "Restore" tab. -- Drag the startup volume (original name "Macintosh HD") to the "Source" field. -- Drag the ext. HDD to the "Destination" field. -- Click "Restore. -- Wait... a long time. -- When it is done, quit Disk Utility. Now you have a perfect, bootable clone of the current system. Start remodeling the system as you wish based on the paragraph above "All the old files are..." Next vacation, turn off the computer, unplug the power adapter, and put it away.
Will a macbook pro (a1281) boot without a hard drive?
I am currently repairing a macbook pro which does not have a hard drive. When turned on, the fans spin up and then after a second stop. My question is whether macbooks boot to a bios or similar even if they dont have a hard drive installed?
