Apple’s APFSD Process Causing High CPU Usage on Macs

Recent reports from users indicate that the “apfsd” process on Apple computers is causing significant CPU usage, raising concerns among Mac users. This increase in processor activity was first noted after a software update to macOS 15.8, which many users found compatible with their hardware. The CPU usage appears to be abnormal, as indicated by one user’s observation of 226.2% CPU utilization attributed to the apfsd process, leading to overheating issues and observations of warm Mac cases.

Many users might not regularly monitor their Activity Monitor, but the recent spike in CPU activity has prompted this action among those affected. Prior to the update, users reported that the CPU usage typically remained near zero, suggesting that the behavior exhibited by “apfsd” may be linked directly to the recent software changes. This shift in performance has sparked discussions and inquiries on platforms such as MacRumors, where community members share their experiences and seek advice.

While the exact cause of the high CPU usage remains unclear, users are advised to report their experiences to Apple support, as such feedback can be crucial for resolving potential software issues. It highlights the need for ongoing communication between users and developers, especially in light of significant updates that can affect system performance. Apple has a history of addressing software-related anomalies and may respond to user feedback to ensure optimal performance of their devices.

As the situation develops, users are encouraged to monitor their CPU usage and reach out for assistance if the issue persists. The importance of maintaining system stability following updates cannot be overstated, particularly for professionals and others who rely heavily on their devices. Continued observation and reporting will be vital in understanding whether the post-update behavior represents a widespread problem or a localized issue affecting only a portion of users.
