Overview

• Internal macOS Tahoe code references an unreleased MacBook Pro equipped with an M5 Pro processor and Apple’s Centuari 5G modem (C1).
• Separate identifiers for a next-generation C2 modem (model C4020) appear in other code segments, fueling uncertainty over which chip will debut in Macs.
• Industry observers emphasize that these code-level trials do not confirm a consumer release of a 5G-capable MacBook Pro.
• The M5 Pro MacBook Pro’s launch window reportedly shifted from fall 2025 to early 2026 in line with broader development timelines.
• Apple plans to expand its in-house modem lineup across multiple devices to boost performance and reduce long-term reliance on Qualcomm.
