The above technique is a myth . See [this video] . Trying to randomly unsolder and put back resistors or other components when you don’t know what the error is is another bad idea. The author should have tried to actually attempt to fix the logic board first. But before all that he should have inspected the board and use a voltmeter to see what the issue is. But even doing that he might need a replacement part.

Yes. How many do you want? Here, he said that Apple puts a chip to break MacBooks after 3 years.

The newest "vintage" Apple product in late 2018, is from 2011: [LINK]
