AWS launched M4 and M4 Pro Mac instances powered by Apple's latest M4 silicon, offering up to 20% better build performance compared to M2 instances. The M4 variant features a 10-core CPU with 24 GB unified memory, while the M4 Pro includes a 14-core CPU with 48 GB memory. Both provide 2 TB local storage and are designed for building, testing, and signing iOS and macOS applications with Xcode. The instances are available as dedicated hosts with per-second billing but require a 24-hour minimum allocation period. Currently available only in US regions (Northern Virginia and Ohio), they support macOS Sequoia 15.6 and newer, though they come at a higher price point than previous generations.
