M1 Firmware Update: What's New in Version 2.03?

v2.04

Based on the average release cadence for M1 platform firmware, is likely 6–9 months away and may include:

• ✅ Backed up your data.
• ✅ Confirmed your device’s current firmware version.
• ✅ Downloaded v2.03 from an official source.
• ✅ Followed the correct installation method for your OS.
• ✅ Verified the update with a benchmark and sleep test.

• Solution: v2.03 may reset the security flags. Open Disk Utility → First Aid → Repair disk. If that fails, reboot into Recovery Mode (Apple Silicon: hold power button), open Terminal, and run diskutil resetFusion.
