Apple 8 manual Troubleshooting

Troubleshooting

They may be rare, but every computer user inevitably experiences seemingly severe computer problems, at some point. These may be crashes where the mouse freezes, the screen locks up, or the display is plastered with error messages. Even mature, well- written operating systems cannot protect you completely from hardware conflicts, bugs, or other problems.

Experience has shown that such system problems are rarely caused by a defect in Apple programs or hardware products. All Apple hardware and software is rigorously tested by a diverse range of musicians and studio users, from a variety of fields and uses, who look for any faults or problems.

This doesn’t mean that the possibility of errors can be completely ruled out; problems can crop up periodically. This is not unexpected—as the various applications, operating system versions, and drivers—are all developed, and improved in parallel by unrelated programming teams. This can lead to occasional compatibility problems. Apple provides fixes in the form of software updates, as soon as such problems are identified. Apple is always grateful to users who report any problems.

If you suffer from system crashes or errors, you may find the tips in this chapter helpful, even if the problems are ultimately unrelated to Apple products. In most cases, these problems, once identified, can be rectified with a minimum of effort, although tracing the cause of such problems can be time consuming. You can overcome most of these problems without needing to consult an expert—this chapter will guide you on how to proceed. It is best to eliminate the classic causes of problems before you suspect a hardware defect, or another fault—especially before sending your machine in for repair, or your software for a refund. Take care, though: some of these suggestions may only cure the symptoms, and could therefore complicate the identification of the actual cause of the problem. Persistent problems will require the advice of an expert.

If you bought your computer and audio hardware at the same time, it is a good idea to test that the computer is functioning as expected—with just a mouse, keyboard, and display attached—before installing the audio interface and additional hardware (external hard disks, printers etc.). All new Macintosh computers ship with pre-installed software, which should allow you to test that everything is working correctly. Once you have switched everything off, you can proceed with the installation of any additional hard disks, modems, scanners, and so on, if applicable. Once done, check that everything is working as it should be. If so, you can unplug all cables from the back of the computer and begin the installation of your audio hardware.
