A MacBook typically lasts 5–8 years depending on model, usage, and software needs. Higher-end models like the MacBook Pro last longer due to better cooling and components, while M1 and later MacBooks run cooler and more efficiently. Software support lasts about three years per macOS version, after which security updates and app compatibility decline. Performance can degrade over time due to full storage, background processes, and lack of upgrade options in newer models. Some users reset their systems periodically, while others upgrade when slowdowns become noticeable. Proper care and lighter use can extend a MacBook’s lifespan beyond the average range.
MacBooks are built to last several years, but how long they actually serve you well depends on usage, hardware quality, and how up-to-date you need to stay. Most people get around 5–7 years out of a MacBook before noticing slowdowns or compatibility issues, though some manage more with lighter use.

Build Quality Affects Longevity
Apple designs MacBooks to be durable, but not all models age the same. Higher-end models like the MacBook Pro tend to have better cooling systems and more robust components than the thinner, fanless MacBook Air models (especially pre-M1 ones).

- Older Intel-based MacBooks often suffer from thermal throttling under heavy load.
- M1 and later Apple Silicon MacBooks run cooler and more efficiently, which helps them stay usable longer.
- The build itself matters too—machined aluminum lasts better than plastic or flimsy metals.
If you're rough with your gear—frequent travel, coffee near the keyboard, screen twisting—it may not make it past four years without a repair or two.
Software Support Keeps Them Relevant
Even if the hardware holds up, eventually software becomes the limiting factor. Apple typically supports each macOS version for about three years. So, a MacBook that can't run the latest macOS is effectively outdated for many modern tasks.

- New apps often drop support for older OS versions after a few years.
- Security updates stop once a MacBook is no longer supported, which is a bigger deal than most realize.
- If you're not updating your OS regularly, you're missing performance improvements, features, and protection.
For example, a 2015 MacBook Pro maxed out at macOS Ventura, meaning it won’t officially support anything newer like Sonoma or Sequoia.
Performance Degradation Over Time
You might notice your MacBook slows down after a few years—not always due to hardware failure, but because of accumulated data, background processes, or heavier software demands.
- Startup disks filling up can cause sluggishness, especially on older models with less storage.
- Background apps and extensions pile on system resource use over time.
- Upgrading RAM or storage used to help, but with soldered-in components in recent models, you’re stuck with what you bought.
Some users reset their laptops every couple of years to keep things snappy, while others just upgrade sooner than expected when things start to lag.
In short, a MacBook usually lasts between 5–8 years depending on model, care, and how current you need to stay. It’s not overly complicated, but there are definitely factors that make some last longer than others.

For example, copying several GB of data to an external hard drive may take several hours. Then the Mac will not be doing any work during the process, and the screen will automatically turn off. Sometimes we even forget that the file copy has not been completed, but the MacBook "Screen" command has been turned off. Mac enters SleepMode, but will file transfers be interrupted? Entering SleepMode will not interrupt file transfer. If the user's MacBook or Mac is always connected to the power supply, and the Mac enters SleepMode, will file transfer be interrupted?
