MacBook keyboard debris: follow Apple's compressed-air angles

Apple recommends a specific angled compressed-air technique for eligible MacBook keyboards with sticky or unresponsive keys: hold at about 75 degrees, keep the nozzle about 1.5 cm away and never invert the can.

If a MacBook key feels different or fails to respond, avoid prying off keycaps. Apple's guidance applies to MacBook (2015 and later) or MacBook Pro (2016 and later) with affected keys, while ordinary exterior wiping uses a soft lint-free cloth.

0 / 6 done

Confirm the Mac model and symptom. Do not assume that every laptop supports Apple's compressed-air procedure.
Shut down the Mac and unplug the power adapter and connected cables. Do not pry off keys or insert metal tools into gaps.
Gently wipe key surfaces with a soft, dry lint-free cloth; never spray cleaner directly on the keyboard.
For the eligible models, hold the Mac at about 75 degrees and sweep compressed air left-to-right with its straw around 1.5 cm from the keys.
Tilt the Mac onto its right side and repeat, then tilt onto its left side and repeat. Do not invert the compressed-air can.
If the key remains unresponsive or liquid was spilled, stop DIY attempts and arrange an Apple-authorized service assessment.
