MacBook Display Cosmetic Grading
Explanation of iFixit cosmetic grading standards for MacBook display assemblies.
Functional Testing
- All used MacBook Pro display assemblies from 2016 or earlier models (as well as models A2141 and A1534), regardless of cosmetic condition, have been tested for full functionality.
- All used MacBook Air display assemblies from 2020 or earlier models, regardless of cosmetic condition, have been tested for full functionality.
- Used MacBook display assemblies are required to meet the same functional specifications as our new products. Those that do not meet this standard are rejected.
- Used MacBook display assemblies are classified as A-Stock, B-Stock, C-Stock, and Delaminated based solely upon cosmetic condition.
A-Stock
- A-Stock displays are in excellent condition, often with no cosmetic blemishes.
- One or two faint scratches on the glass surface – not visible when the display is on – are considered acceptable at this grade.
- Scratches (if any) will not be deep enough to be felt with a bare finger.
- Minor wear on the rubber bezel is acceptable.
B-Stock
Display assemblies will be classified as B-Stock if they have one or two of these cosmetic issues:
- Several faint scratches on the glass that do not interfere with visibility when the display is on.
- One or two deep scratches that do not exceed 10mm (2/5th of an inch) in length.
- Scratches or buffed areas on the metal casing that cannot be felt by a bare finger and do not exceed 25% coverage.
- Scratches or dents on any integrated plastic frame or rubber bezel.
- Refurbished metal casing with perceptibly changed texture.
Examples of B-Stock cosmetics
C-Stock
Display assemblies will be classified as C-Stock if they have one or two of these cosmetic issues:
- Several faint scratches on the glass that do not interfere with visibility when the display is on.
- Scratches, buffed areas, or small dents in the metal casing that does not exceed 25% coverage. Scratches can be significantly longer and deeper than B-stock.
- Scratches or dents on any integrated plastic frame or rubber bezel.
- Minor dents in the corners of the metal casing
Examples of C-Stock Cosmetics
Delaminated
The delaminated category only applies to certain models of MacBook Pro Retinas which include an “anti-reflective coating” on the glass surface that can begin to wear off with time. All delaminated display assemblies will share cosmetic grading with C-Stock assemblies, with the addition of delamination on the screen that does not interfere with visibility when the display is on. Please note: delamination will become worse if cleaning solutions are applied to the screen.
Examples of Acceptable Delamination
Examples of Unacceptable Delamination
Rejected
We reject any used displays that have:
- Any functional issue.
- Cracked glass.
- Damage that obscures or distorts the display.
- Liquid damage.
- Missing subcomponent(s).
- Damaged cables or connectors.
- Stripped screws (if applicable).
