Restarting a Mac is useful

Sometimes a Mac can be stuck because of a bug in a software. It’s often because of memory leaks from apps.
Restarting a Mac due to a memory leak from software is beneficial for several reasons:

  1. Reclaiming Memory:
    The most direct effect of restarting is to reclaim memory that has been lost to the leak. Memory leaks occur when a program fails to release memory it no longer needs. Over time, this can consume a significant portion of the system’s RAM, leading to slow performance and, in extreme cases, system instability.
  2. Resetting System State:
    Restarting a computer resets its state, including all running processes and services. This can resolve issues caused by software bugs or processes that have become unstable or are consuming excessive resources.
  3. Improving Performance:
    As the system’s memory gets clogged due to a leak, it can slow down not just the offending application but also other programs and the operating system itself. Restarting can often result in noticeable improvements in overall system performance.
  4. Preventing Data Loss:
    Continuous operation with a memory leak can lead to situations where the system or applications crash unexpectedly, potentially leading to data loss. Restarting pre-emptively after noticing a memory leak can prevent such scenarios.
  5. Troubleshooting:
    Restarting is a basic troubleshooting step. If the problem persists after a restart, it’s an indication that the issue might be more serious or inherent in the software, requiring further investigation or updates.

It’s important to note that while restarting can temporarily resolve the issue, it’s not a permanent solution to memory leaks. Ideally, the software causing the memory leak should be updated or fixed to prevent the problem from recurring.
