When you turn on your Mac, the first thing that it does (after the hardware tests) is to check for a startup disk with Mac OS 9 or X on it. If your system doesn’t find such a disk on your internal hard drive, it begins looking elsewhere — on a FireWire or Universal Serial Bus (USB) disk or on a CD or DVD.
Assuming you have backups of your important stuff, you can reinstall Mac OS X on your Mac. This is much simpler than reinstalling Windows — you don’t have to download any installation media. You can just boot into a special recovery mode, start the installation, and your Mac will download everything it needs from Apple. If your problem is that your Mac has frozen in the middle of a task, or an app has become unresponsive, it is possible to Force Quit it by right clicking/control clicking on its icon in the Dock. Fix your Mac with these simple troubleshooting tips. Got a Mac that's not behaving itself? Here are some simple things you should try before taking it to a Genius at your nearest Apple Store. If your Mac is suddenly suffering hardware or software issues, or is generally acting up you can run sysdiagnose in Mac OS X Terminal.Sysdiagnose compiles a number of advanced technical reports for expert Mac users to review and troubleshoot appropriately.
If your Mac can’t find your hard drive (or doesn’t find on it what it needs to boot OS X), you encounter a flashing-question-mark icon or the prohibitory sign.
If you encounter any of these warning icons, go through the following steps in the order listed, starting with Step 1. Then, if one doesn’t work, move on to the next.
Step 1: Run First Aid
In most cases, after you’ve booted successfully from the OS X CD, the first logical troubleshooting step is to use the First Aid option in the Disk Utility application.
Every drive has several strangely named components such as B-trees, extent files, catalog files, and other creatively named invisible files. They’re all involved in managing the data on your drives. Disk Utility’s First Aid feature checks all those files and repairs the damaged ones.
Here’s how to make First Aid do its thing:
1. Boot from your Mac OS X CD by inserting the CD and restarting your Mac while holding down the C key.
The OS X Installer appears on your screen.
2. Drivers compatible usb port mouse. Choose Installer –> Open Disk Utility to launch the Disk Utility application that’s on the CD.
3. When the Disk Utility window appears, click the First Aid tab to select that function of Disk Utility.
4. Click the icon for your boot hard drive at the left of the Disk Utility window.
Your boot drive is the one with OS X and your Home folder on it.
5. Click the Repair Disk button.
Your Mac whirs and hums for a few minutes, and the results window tells you what’s going on. Ultimately, First Aid tells you (you hope) that the drive has been repaired and is now okay. If so, go back to work.
6. Quit Disk Utility by choosing Disk Utility –> Quit Disk Utility or by pressing Command+Q.
7. Reboot without holding the C key down.
If First Aid finds damage that it can’t fix, a commercial disk-recovery tool may be able to repair the damage.
If everything checks out with First Aid, eject the CD and try to boot from your hard drive again.
Step 2: Safe Boot into Safe Mode
Booting your Mac in Safe Mode may help you resolve your startup issue by not loading non-essential (and non-OS X) software at boot time. You do it by holding down the Shift key during startup.
Keep holding down Shift until the Finder loads completely. If your Mac is set up so that you don’t have to log in, keep pressing the Shift key until the Finder loads completely. If you do log in to your Mac, type your password as usual, but before clicking the Log In button, press the Shift key again and hold it until the Finder loads completely.
You’ll know you held the Shift key long enough if your Startup Items don’t load (assuming that you have Startup Items; you can create them in the Accounts System Preference pane, although some programs create them for you).
Booting in Safe Mode does three things to help you with troubleshooting:
- It forces a directory check of the startup (boot) volume.
- It loads only required kernel extensions (some of the items in /System/Library/Extensions).
- It runs only Apple-installed startup items (some of the items in /Library/Startup Items and /System/Library/Startup items). Note that the startup items in the Library folders are different from the Startup Items in the Accounts System Preference pane.

Taken together, normally these changes can work around issues caused by software or directory damage on the startup volume.
Some features, such as DVD Player, do not work in Safe Mode. Use Safe Mode only if you need to troubleshoot a startup issue.
If your Mac boots in Safe Mode, you may be able to determine what is causing it — usually a damaged Preference file (in Home/Library/Preferences) or one of your Startup Items (in the Accounts System Preference pane).
Step 3: Zapping the PRAM
Sometimes your parameter RAM (PRAM) becomes scrambled and needs to be reset. PRAM is a small piece of memory that’s not erased or forgotten when you shut down; it keeps track of things such as printer selection, sound level, and monitor settings.
PRAM stores these settings:
- Time zone setting
- Startup volume choice
- Speaker volume
- Recent kernel panic information, if any
DVD region setting
To reset your PRAM, restart your Mac and press Command+Option+P+R until your Mac restarts itself. You may see the flashing question mark or spinning-disk cursor — then the icon disappears, and your Mac chimes again and restarts. Most power users believe you should zap it more than once. Now restart your Mac without holding down any keys.
Remember that your chosen startup disk, time zone, and sound volume are reset to their default values when you zap your PRAM. So after zapping, open the System Preferences application to reselect your usual boot disk and time zone and set the sound volume the way you like it.
Step 4: Reinstalling OS X
Reinstalling the system software last takes the longest and is the biggest hassle. If you’re still unsuccessful, you’ll have no choice but to consider Step 5.
Step 5: Take your Mac in for repair
If none of these suggestions work for you and you’re still seeing anything you shouldn’t when you start up your Mac, you have big trouble.
You may have any one of the following problems:
- Your hard drive is dead.
- You have some other type of hardware failure.
- All your startup disks and your system-software CDs are defective (unlikely).
The bottom line: If you still can’t start up normally after trying all the cures here, you almost certainly need to have your Mac serviced by a qualified technician.
If your Mac is suddenly suffering hardware or software issues, or is generally acting up you can run sysdiagnosein Mac OS X Terminal. Sysdiagnose compiles a number of advanced technical reports for expert Mac users to review and troubleshoot appropriately. Sysdiagnose will output the following information in a tar.gz file.
- Crash report
- Input/Output details
- Disk information
- Compiled system profiler report
- System logs (including kernel logs)
- Filesystem usage report
- Memory usage and processes details
- Powermetrics
In reality, Sysdiagnose is ran and performed by Mac OS X technical specialists including Apple store engineers (Genius Bar) and authorized Mac repair shops. The sysdiagnose report is run on Mac X systems as a last or first resort to solving and understanding complex technical hardware and software issues.
Get Started Running Sysdiagnose in Terminal
1. Open Terminal (Applications -> Utilities -> Terminal)
2. Type the following command in Terminal. Be prepared to wait about 2 to 5 minutes for Sysdiagnose to completely run.
You will receive the following warning prompt:
