The wedge-shaped profile gracefully tapers from the rear to a slim edge profile up front.

Memory & Storage

Configurable options include:

• Unified memory of 16 GB or 24 GB, sufficient for multitasking, light creative work, or running VMs and apps simultaneously

• SSD storage offerings starting at 512 GB, scaling to 2 TB maximum. SSDs provide rapid read/write speeds, enabling quick project load times and smooth app responsiveness

Unified memory ensures efficient resource sharing between CPU, GPU, and the Neural Engine, optimizing overall system responsiveness.
