Apple has expanded its High Power Mode to the MacBook Pro and Mac mini models featuring the new M4 Pro and M4 Max processors. The development of High Power Mode, which began with macOS Monterey on the 16-inch MacBook Pro with the M1 Max chip, enables users to boost their systems during demanding tasks such as video editing and 3D modeling.
Performance Boost with a Catch
High Power Mode, designed to improve performance by increasing the cooling system’s capability, results in fans running at higher speeds, which can cause more noticeable noise. The mode is ideal for scenarios where the Mac is plugged in, given its increased energy use.
According to Apple’s support documentation, High Power Mode can enhance performance during graphics-intensive tasks like 8K ProRes 4444 video color grading.
Introduced with macOS Monterey, High Power Mode first became available in the 16-inch MacBook Pro M1 Max. Early adopters noted improved performance but also increased fan activity. The feature expanded to models equipped with the M2 Max in 2023, illustrating Apple’s ongoing commitment to meeting the needs of professional users seeking consistent performance under heavy workloads.
Initial user feedback on High Power Mode with the M4 Pro and M4 Max has been varied but generally positive, highlighting both advantages and trade-offs. Early tests report that the mode delivers noticeable performance gains, particularly during tasks such as 8K video editing and real-time 3D rendering. The increased cooling capability and extended performance are evident during long editing sessions, making the mode a valuable tool for professionals.
These improvements come with the expected increase in fan activity, a familiar aspect for users who previously engaged with this mode on the M1 Max and M2 Max models.
Reviewers have noted that while the performance boost allows for smoother playback and faster export times, the fan noise becomes more prominent under heavier workloads. This marks a shift for users accustomed to the quieter operation that Apple Silicon typically offers. Some users point out that the overall responsiveness of applications that rely heavily on GPU and CPU resources has improved, with fewer slowdowns when multitasking between demanding software.
Despite the enhanced cooling and sustained performance, initial observations suggest that the power mode is most beneficial when the device is plugged in, as it significantly impacts battery life. Users who push their devices to the limit in High Power Mode while on battery power report a quicker drain, indicating that the feature is best suited for stationary, power-connected use.

Benchmarking Apple’s M4 Chips
Apple’s M4 series, released in October, marked a leap in processing capabilities. The M4 Max recorded a single-core score of 4,060 and a multi-core score of 26,675 in Geekbench 6, outperforming Intel’s Core Ultra 9 285K by 19% in single-core and 16% in multi-core tests.
The 16-core CPU and 40-core GPU configuration is particularly suited for high-intensity work like 3D rendering and video production. Meanwhile, the M4 Pro, which includes a 14-core CPU and 20-core GPU, remains an efficient option for professional workflows.
Thunderbolt 5 and Memory Enhancements
The inclusion of Thunderbolt 5 in the M4 MacBook Pro and Mac mini provides data transfer speeds of up to 120 Gbps, a notable jump from Thunderbolt 4. The feature is critical for users working with large files or connecting multiple high-resolution displays.
Backward compatibility ensures continued use of existing peripherals without sacrificing speed. The M4 Max’s support for up to 128GB of unified memory further benefits professionals who need robust multitasking and efficient data handling.
AI Tools and the Neural Engine
Both the M4 Pro and M4 Max include an updated 16-core Neural Engine that accelerates machine learning tasks, enhancing Apple’s suite of AI tools known as Apple Intelligence. The AI suite supports tasks like proofreading and summarizing, which are processed locally for privacy, while more complex operations utilize secure cloud computing. An upcoming update in December 2024 will further enhance Siri’s capabilities by integrating ChatGPT, enabling smoother cross-application workflows.
Mac Mini and Compact Power
The refreshed M4 Mac mini, launched alongside the updated MacBook Pro, packs powerful processing into a compact form, with prices starting at $599. The M4 Pro version of the Mac mini includes Thunderbolt 5 and a 14-core CPU with a 20-core GPU, offering a solution for demanding creative tasks without the footprint of a full workstation. This makes the Mac mini a versatile option for users needing robust performance in a small package.
The M4 series continues the iterative advancements seen in Apple’s Silicon roadmap. The original M1 series laid the groundwork with a focus on energy efficiency, while subsequent generations improved processing power and memory bandwidth. The M4 chips, leveraging second-generation 3nm architecture, maintain a balance of high performance and efficient energy use. The M4 Pro even surpasses the M2 Ultra in multi-core performance, showcasing Apple’s optimized chip design.
Apple’s transition from the M1 to the M4 series showcases steady improvements, including increased core counts and refined architectures. The M4 Pro and M4 Max build on the company’s legacy by offering enhanced performance with high energy efficiency.
