Original Display Check
Check repair history and replacement clues
Bottom lineOn macOS Tahoe 26 or later, open System Settings > General > About > Parts & Service: if the display is listed, it was replaced (display records are shown on M5 and newer Macs). On older Macs, check that True Tone and auto-brightness work and look for pry marks around the bezel; a missing True Tone option on a model that supports it usually means a non-genuine replacement screen.
Check Parts & Service (if available)
On Apple silicon Macs running macOS Tahoe 26 or later, go to Apple menu > System Settings > General > About > Parts & Service. This option appears only if a repair was detected — no option usually means no repair on record. Display history is currently shown only on the newest models (e.g. M5 MacBook Pro/Air)
Open System Report
Apple menu > System Settings > General > About > click “System Report…”
Review Built-In Display Details
In the sidebar choose Graphics/Displays and check the built-in display entry. Some Macs show vendor or panel details, but a display serial number may not appear
Check True Tone and Auto-Brightness
Open Control Center > Display or System Settings > Displays. True Tone and ambient light response should work normally if your model supports them
Inspect for Repair Signs
Check the bezel, lid alignment, and screw marks for signs that the display assembly was opened or replaced
Tip: Parts & Service labels parts as Genuine, Used, Unknown, or Unverified and is the strongest official evidence where available. On models before M5, display history is not shown — rely on True Tone, vendor info, and bezel condition.
