Mac OSX: How To Get Peak Performance

Disk maintenance: You can launch Disk Utility, which can be found in the Utilities folder in the Applications folder on your hard drive, to perform checks on your hard drive and other forms of media (floppies, Zip disks, etc.). If you suspect your hard drive has a problem, you will need to boot the computer from the original installation CD that came with it and launch the copy of Disk Utility that is located in the Utilities folder of that disk. The computer should boot automatically from the installation CD if it is restarted with the disk in the drive, however, to force the computer to boot from the CD, simply hold down the C key on the keyboard until the Mac OS splash screen appears. Once you locate the Disk Utility icon, simply double-click on it and it will launch:

Notice to the left a list of mounted drives appears: in this picture, a hard drive and an iPod mounted as a hard drive. To the right there are a selection of 5 different tabs to choose from. The Information tab gives you basic information about the drive you have selected to the left (such as size, format, and both used and available space on the drive). The Erase tab is used for erasing or reformatting drives, whether they be floppies, hard drives, or CD-RW disks. The Partition tab allows you to reformat a drive into separate partitions, so that one drive can function as multiple separate drives. The RAID tab allows you to connect several hard drives together, so that they act as one large very fast hard drive. For our purposes, above you will notice that the First Aid tab is selected. Here, you can either Verify or Repair Disk Permissions, if you’ve been having trouble deleting files or getting error messages saying that “You do not have adequate permission.” This is a useful function to perform should your system begin behaving erratically. If you have booted from some other drive besides your normal System drive, or if you select another drive besides the System drive, you will also have the option to Verify or Repair the disk. A description of the progress for any of these scans will appear in the blank white window above the buttons, complete with an announcement at the end of whether the repair was successful or if the disk was found to not be in need of repair. Should Disk Utility be unable to repair the disk, it will say so. Then you should consider either investing in a commercial program such as Norton Disk Doctor or DiskWarrior to attempt to repair the disk. Should all else fail, navigate to the Erase tab of Disk Utility (after backing up the contents of the disk, of course) and reformat the drive by selecting it in the menu to the left and choosing Erase.

Should a program freeze: Due to improved memory handling in OS X, a frozen program should not affect the rest of your computer’s stability. If a program freezes or fails to respond simply hold down on the Command+Option+Escape keys simultaneously, and the following window will appear:
Simple select the program that is not responding (normally, a program that is not responding will appear in red in the list) and click the Force Quit button to force it to quit. Usually, you can immediately re-launch the program that had frozen and continue working without any further difficulties. Simply close the Force Quit Applications window by clicking the small button in the upper left corner of the window.

Mac OS9: How To Get Peak Performance

Disk maintenance: You can launch Disk First Aid, which can be found in the Utilities folder on your hard drive, to perform checks on your hard drive and other forms of media (floppies, Zip disks, etc.). If you suspect your hard drive has a problem, you will need to boot the computer from the original installation CD that came with it and launch the copy of Disk First Aid that is located in the Utilities folder of that disk. The computer should boot automatically from the installation CD if it is restarted with the disk in the drive, however, to force the computer to boot from the CD, simply hold down the C key on the keyboard until the Mac OS splash screen appears. This screen will look like the regular splash screen except there should be a repeated image of a CD in the background to let you know that you have started from the CD. Once the computer has booted from the CD follow these steps:
• Locate the Installation CD on the Desktop.
• Double click on the Installation CD, opening its window.
• Find the Utilities folder on the Installation CD. If it is not in the main window of the CD, then look for it within the Extras folder or possibly within the System folder. The location will vary depending upon the version of the installation disk.
• Once you find the Utilities folder, locate the Disk First Aid icon and launch the program by double-clicking on it.
• Once the program has launched, choose the disk that you wish to examine from the list on the left (if the disk doesn’t appear, try refreshing the list by selecting “rescan for disks” from the drop down menus) and then select either the Verify or Repair button. Verify simply checks the disk to make sure everything is OK. Repair both checks the disks and fixes any errors that it finds.
• As the computer scans, a small list of what it is doing will appear in the bottom window of Disk First Aid. When the computer finishes scanning the disk, it will
either say “no problems were found,” “problems were found and have been repaired,” or “Disk First Aid was unable to repair the disk.”
• Should Disk First Aid be unable to repair the disk, you can either invest in a commercial program such as Norton Disk Doctor to attempt to repair the disk, or backup the data on the disk (if possible), and either erase the disk completely, or if it is your harddrive, erase the disk and perform a clean reinstallation of the System Software.

Should a program freeze: Should a program freeze or become unresponsive, hold down the Apple/Command key + the Option Key + the Escape key simultaneously. A dialogue box should appear asking if you are sure you wish to Force the program to Quit. Sometimes you can select “Cancel” and this dialogue box will have been enough to unfreeze the program. If this doesn’t work, select “Force Quit” and wait for the program to close. Restart the computer. If attempting to Force Quit the program fails, you will have to force the computer to restart, either by locating the reset button on your computer or by holding down the power button for 10 seconds until the computer powers down. Restart the computer.

Should the computer freeze at Start Up: Should your Macintosh freeze at Start Up, you most likely have an extension conflict. In order to remedy this situation hold down the Shift key at start up. This will disable all your extensions. Once the computer starts, navigate to the Control Panels folder within your System folder and launch the Extension Manager. This control panel allows you to enable or disable different extensions to try to resolve extension conflicts. It is best to create a new Extension set within Extension Manager before installing new software, so that if there are any errors after installation, you can simply restart with the Shift key held down and choose this Extension set to undo the harm caused by the program.
