Error Codes
Troubleshooting
View all →Common Failure Modes
Because everything (RAM, SSD) is soldered to the motherboard, single component failures require replacing the entire logic board. Screen damage from debris closed in the lid and battery degradation are the most common physical issues.
Maintenance
View all →Check Battery Health
Lithium-ion batteries degrade over time, affecting mobility. Monitoring health alerts you when a replacement is needed to prevent unexpected shutdowns.
Clean Keyboard and Screen
Oils from fingers degrade the keyboard coating and transfer to the screen when closed. Wiping down the laptop preserves its aesthetics and functionality.
Clear Storage Space
macOS requires significant free space for swap memory and system updates. Offload old files to external drives to keep the system responsive.
