If Disaster Strikes

Your first priority should be to make a backup of your most important documents. Attempt to copy your files (lyrics, songs, tax records) to other hard, or removable drives, without launching their associated applications. You can skip this step for CD-ROMs, but be aware that even CDs require a little care when handling: neither side of the disk should be scratched. Once you have made backups of your files and programs, the chances of a true disaster are all but eliminated. Never skip making regular backups, even if everything is working perfectly—eventually, any hard disk may crash!

A system crash can be caused by:

ÂOperator error

ÂA software conflict (incompatibility between two programs, or a virus)

ÂA hardware configuration error

ÂOverloading the system’s resources

ÂFaulty cable connections (or missing termination)

ÂA hardware defect

Eliminate the first five causes before deciding to have your hardware repaired.

If the problem persists, make precise notes of the following:

ÂWhat you were doing at the time of the error (which program, which function, which applications were open).

ÂThe exact text of any error messages and/or error numbers (if applicable).

ÂThe version of the operating system, as well as that of the program in which the error occurred.

ÂThe Apple System Profiler, installed with Mac OS X, offers an in-depth component overview, which can be printed.

ÂWhich System Preferences (found in the Apple menu) are active.

Note: The Apple System Profiler can be used to print details of your entire system configuration, including the properties of all hardware.

Preferences and Parameter RAM

Many crashes can be avoided by taking one of the following measures (please exit the program first):

ÂMove or delete the preferences of the program that is crashing. The preferences files are found in your User folder ~/library/preferences. Drag the preference file to the desktop. Doing so will often require you to reset some of your program’s preferences.

“Zap” the Parameter-RAM (P-RAM). This contains clock time, date, and many system settings which are preserved when the computer is turned off. You can easily reset them. Hold the Command-Option P and R keys during a restart (immediately after hearing the start sound). Keep the keys held until you hear the Macintosh start sound three times.

8 specifications

The Apple iPhone 8, introduced in September 2017, marked a significant evolution in the company's smartphone lineup, bridging the design elements of the past with cutting-edge technology. The iPhone 8 brought several notable features and advancements that enhanced user experience and performance.

One of the most striking design elements of the iPhone 8 is its glass back, a departure from the aluminum unibody design of its predecessors. This transition not only provided a fresh aesthetic appeal but also enabled wireless charging, allowing users to power their devices conveniently without the need for cables. The iPhone 8 supports Qi wireless charging standards, making it compatible with a wide array of wireless charging pads.

Under the hood, the iPhone 8 is powered by Apple’s A11 Bionic chip, which features a six-core CPU. This powerful processor significantly improved the iPhone's speed and efficiency when compared to previous models. The A11 Bionic was designed for machine learning applications and includes a dedicated neural engine, allowing for better performance in tasks such as image recognition and augmented reality experiences.

The display of the iPhone 8 is a 4.7-inch Retina HD display, boasting True Tone technology, which adjusts the screen's white balance based on the ambient light. This feature not only enhances color accuracy but also improves comfort for users by reducing eye strain in various lighting conditions. With a resolution of 1334 x 750 pixels, the display delivers sharp and vibrant visuals.

Camera capabilities on the iPhone 8 also received significant upgrades. The rear 12-megapixel camera features optical image stabilization, providing clearer photos and smoother video recording, even in low light conditions. The introduction of new color filters and a larger sensor allowed for improved photo quality. The front-facing 7-megapixel camera supports 1080p HD video recording and features advanced portrait mode, offering users new ways to create professional-quality selfies.

Another important aspect of the iPhone 8 is its robust security features. The device continued to use Touch ID for biometric authentication, ensuring that users' data remained secure. Additionally, the iPhone 8 was water and dust resistant, rated IP67, which added an extra layer of durability.

In summary, the Apple iPhone 8 successfully combined innovative technology with timeless design. Its wireless charging, powerful A11 Bionic chip, enhanced camera features, and sturdy build quality made it a compelling choice for consumers looking to experience the best of Apple’s engineering prowess.
