Durability of a MacBook

Apple's MacBook line is well-known for its design; much like Apple's other products, the MacBook was designed with aesthetics in mind. However, it was also built to be rather sturdy, given the usual, fragile nature of laptops in general. Despite some issues, especially with older models, MacBooks are durable devices that can handle plenty of wear and use.

Scratching

The outer casing of MacBooks can be susceptible to scratching, especially if it's being moved around a lot. The aluminum-cased models are less prone to this. Any minor scratching isn't very visible unless being viewed under direct light, and a microfiber cloth can take care of many small scratches or abrasions.

Denting, Chipping and Cracking

If you ever drop your laptop, there's a chance the casing can become damaged. Again, aluminum models tend to be less susceptible to this type of damage, but where the white and black models may get chipped or cracked, the aluminum models may get dents. Older models experience more of the cracking, especially near the monitor, by the trackpad and on the corners farthest from the monitor.

Internal Components

Internally, the MacBook is built very well. All MacBook models come with Sudden Motion Sensor technology, which releases the hard drive heads if it detects any sudden movement, such as falling. This helps keeps your hard drive safe as well as preserve the data on it in case of any damage. One common problem with MacBooks is that they tend to run rather hot and the fans run loudly whenever they start rotating at full speed, which can be often.

Screen

Screens have always been one of the most delicate and sensitive parts to any laptop, and the MacBook is no exception. On older models, the plastic around the screen itself can sometimes start to peel away or crack. On new models that use the glass screen, this is not as much of an issue, but although sturdy, glass can still break if dropped. Any damage to the screen can result in internal damage, rendering the screen impossible to view, and they are costly to replace no matter what model you use. However, if you take care of your laptop, screen damage is unlikely, and most MacBooks can deal with slight jarring and jolting without breaking anything.
