State: closed
Merged: No

Describe your changes

Bumps github.com/shoenig/go-m1cpu from v0.2.0 to v0.2.1 to fix a startup crash of netbird-ui on Apple M4/M5 hardware.

v0.2.0 crashes with SIGTRAP on M4/M5 Macs because IORegistryEntryCreateCFProperty returns NULL for voltage-states properties, and CFRelease(NULL) triggers a trap. v0.2.1 adds null checks before CFRelease, fixing the crash.
