Keyboard covers on MacBooks - blessing or curse? Many users apply silicone covers to protect their keyboard, but these can lead to overheating and even display damage. Here are the facts.
The Problem with Keyboard Covers
Why keyboard covers are problematic:
1. Heat Buildup
• MacBooks use the keyboard for heat dissipation
• Silicone covers block this cooling
• CPU and GPU run hotter
• Performance throttling occurs
2. Display Damage
• Added thickness when closing
• Pressure on the display
• Screen cracks possible
• Apple explicitly warns against this
3. Keyboard Problems
• Keys stick due to heat
• Moisture accumulates
• Dirt trapped under cover
• Butterfly keyboards especially vulnerable
Apple's Official Position
Apple explicitly advises against keyboard covers:
- Impairs cooling system
- Risk of display damage
- Tolerances are very tight
- May void warranty
Particularly at risk:
• MacBook Pro 2016-2019
• MacBook Air 2018-2020
• All models with Butterfly keyboard
Recognizing Overheating
Warning signs:
• Fans constantly running at maximum
• MacBook gets very hot
• Sudden performance drops
• kernel_task high CPU usage
• Unexplained crashes
Monitor temperature:
• iStat Menus
• Intel Power Gadget
• Macs Fan Control
• Activity Monitor (CPU usage)
Better Alternatives to Keyboard Covers
1. Regular Cleaning
• Use compressed air spray
• Microfiber cloth for surfaces
• Professional maintenance
• No liquids directly on keyboard
2. Careful Handling
• Don't eat at your MacBook
• Wash hands before use
• Keep drinks away
• Maintain clean workspace
3. AppleCare+
• Covers accidental damage
• Cheaper than display repair
• Professional service
• No DIY solutions needed
What to Do About Overheating?
Immediate measures:
1. Remove keyboard cover
2. Place MacBook on flat, hard surface
3. Quit resource-hungry apps
4. Perform SMC reset
5. Check ventilation slots
Long-term solutions:
• Professional cleaning
• Thermal paste renewal
• Fan cleaning
• Software optimization
• Use laptop stand

Frequently Asked Questions
Are thin keyboard covers safe for MacBooks?
No, even thin keyboard covers can cause problems. Apple's tolerances are extremely tight, and any additional thickness can damage the display when closing the lid. The covers also impair heat dissipation regardless of thickness.
How can I protect my keyboard from spills without a cover?
The best protection is prevention: keep liquids away from your MacBook, use a separate keyboard for risky environments, and consider AppleCare+ for accidental damage coverage. If a spill occurs, immediately power off and seek professional help.
My MacBook already overheats - will removing the keyboard cover help?
Yes, removing the keyboard cover will improve cooling, but if overheating persists, you may need professional cleaning, thermal paste replacement, or software optimization. Persistent overheating can indicate deeper issues requiring expert diagnosis.
