Apple said that this flaw exists in some 13-inch Macbook Pro without Touch Bar, it is not a security issue.
Apple said in its official website that these affected products were produced between October 2016 and October 2017, but the company did not give the actual number of Macbook Pros affected.
Last December, Apple confirmed that a new feature launched by the company for the iPhone 6, iPhone 6s and iPhone SE may reduce the performance of mobile phones. Later, the company apologized for this and changed the battery replacement price of the affected models from 79. The dollar is lowered to 29 U.S. dollars.
