About Model Identifiers
Model identifiers are unique codes that macOS uses to identify specific Mac hardware configurations. These identifiers are essential for:
- System Management: MDM and deployment tools use these to target specific hardware
- Compatibility Checks: Determining which macOS versions support specific models
- Asset Management: Tracking and inventorying Mac fleets
- Support Documentation: Finding model-specific troubleshooting guides
Understanding the Format
Identifier Structure
Model identifiers follow patterns like:
MacBookPro18,3- MacBook Pro with M1 Pro chipiMac21,1- 24-inch iMac with M1 chipMac15,12- MacBook Air with M3 chip
The numbers generally indicate:
- First number: Generation or major revision
- Second number: Specific configuration within that generation
Chip Architecture
- Apple Silicon (M1, M2, M3): Latest Mac models with ARM-based processors
- Intel: Previous generation Macs with x86 processors
