[Bug]: Battery maximum capacity is always shown as 100% on macOS 27.0

[gsmtc01]

App Version

1.0.3

Device Model (iMac/MacBook/Mac mini/etc.)

MacBook Air

OS Version

macOS 27.0

Describe the bug

After updating from macOS 26 to macOS 27.0, RunCat Neo always displays the battery maximum capacity as 100%.

The MacBook Air has a relatively high battery cycle count, and the actual maximum capacity reported by macOS System Information is lower than 100%. Therefore, the value displayed by RunCat Neo does not match the system-reported value.

This issue started after the upgrade to macOS 27.0.

How to reproduce

1. Update macOS from version 26 to version 27.0.
2. Open RunCat Neo.
3. Check the Battery > Max Capacity displayed by the app.
4. Open System Information and navigate to Power > Health Information.
5. Compare the maximum capacity shown by RunCat Neo with the value reported by macOS.

Expected behavior

RunCat Neo should display the same battery max capacity value reported by macOS System Information instead of always displaying 100%.

Screenshots (optional)
