Understanding Cache: The Good, the Bad, and the Ugly

Cache is a temporary storage area on your computer that holds frequently accessed data. It’s designed to speed up your computer by providing quick access to information, but it can also become a bottleneck. As your cache fills up with outdated or unnecessary data, it can lead to slower performance.
The good: Cache helps your computer run faster by storing frequently used data.
The bad: Over time, the cache can become cluttered with outdated information, slowing down your computer.
The ugly: A full cache can lead to app crashes, slow loading times, and overall sluggish performance.

• Slow performance: If your MacBook Air feels sluggish, emptying the cache might help.
• After installing new software: New software can sometimes create conflicts with existing cache data.
• After a system update: macOS updates can sometimes modify system files, leading to outdated cache data.
• If you’re experiencing app crashes: A full cache can sometimes cause apps to crash.
