Apple has acknowledged that thermal throttling is a real issue caused by a software bug, and it's issuing a software update today that is designed to address it.

The company also apologized, writing: "We apologise to any customer who has experienced less than optimal performance on their new systems."

Apple claims that it discovered the problem after further testing in the wake of Lee's video, which showed results that Apple hasn't seen in its own testing.

Apple insists that the throttling was only exhibited under fairly specific, highly intense workloads, which is why the company didn't catch the bug before release. The bug affects every new generation of the MacBook Pro, including both the 13-inch and 15-inch sizes and all of the Intel processor configurations. It does not affect previous generations.

However if the issue is because of a design flaw which does not allow the Intel Chip to stay cool we might start seeing a few expensive Macbooks catching fire.  It will be like the old days all over again.
