"@type": "Question",

"name": "Can I use a hairdryer on a low setting to dry my MacBook?",

"acceptedAnswer": {

"@type": "Answer",

"text": "No. Even on a low setting, a hairdryer concentrates heat unevenly and can push moisture deeper into the chassis. Use the inverted-V gravity method and get it to a specialist within 4-6 hours."

}

},

{

"@type": "Question",

"name": "How long can I wait before bringing my MacBook in for repair?",

"acceptedAnswer": {

"@type": "Answer",

"text": "The ideal window is 4-6 hours. Corrosion begins within 12 hours in Johannesburg humidity. The 72-hour drying advice is a myth."

}

{

"@type": "Question",

"name": "Does putting my MacBook in rice actually work?",

"acceptedAnswer": {

"@type": "Answer",

"text": "No. Rice cannot absorb moisture from inside a sealed aluminium enclosure. It sheds starch dust that adds contamination."

}

},

{

"@type": "Question",

"name": "Will Apple cover water damage under warranty?",

"acceptedAnswer": {

"@type": "Answer",

"text": "No. Apple warranty and AppleCare+ do not cover liquid damage. Apple quotes R15,000-R54,000 for full board replacement. Independent component-level repair costs R1,800-R10,000."

}

{

"@type": "Question",

"name": "Is my data safe if my MacBook got wet?",

"acceptedAnswer": {

"@type": "Answer",

"text": "In most cases, yes. Modern MacBook SSDs store data in flash memory resilient to liquid. Data recovery is often possible under POPIA-compliant protocols."

}

},

{

"@type": "Question",

"name": "What should I do if I already powered on my MacBook after a spill?",

"acceptedAnswer": {

"@type": "Answer",

"text": "Turn it off immediately by holding the power button for 10 seconds. Then flip it inverted-V and bring it to a specialist as soon as possible."

}

},

{

"@type": "Question",

"name": "Does the type of liquid matter for MacBook damage?",

"acceptedAnswer": {

"@type": "Answer",

"text": "Significantly. Water has ~70% recovery rate, coffee ~50%, rooibos tea ~30%, and soft drinks ~20%. Saltwater adds R300-R800 to repairs."

}

{

"@type": "Question",

"name": "How much does MacBook water damage repair cost in South Africa?",
