Apple’s decision to drop Rosetta 2 support in macOS 27 has sparked fierce debate among developers. It’s not just an emulator fading away. The move strips gigabytes of dormant Intel code from Apple Silicon systems, a direct consequence of five years pushing ARM chips. Hoshino Lina, a developer VTuber known for deep systems dives, laid it bare in a viral X thread on April 20, 2026. X post by Hoshino Lina . Rosetta 2 demands the entire macOS framework exist in dual Intel and ARM flavors. Kernel drivers aside, nearly everything runs as Intel code under emulation. Drop Intel hardware support first. Then, with macOS fully ARM-native, Rosetta crumbles. “Rosetta 2 requires almost the entire OS to have Intel support. That’s how it works,” Hoshino wrote. Your Apple Silicon Mac ships with a parallel Intel codebase. Gigabytes idle if Rosetta sits unused. Short-term pain. Developers must recompile. Users lose legacy apps overnight.…
