Apple has released a firmware update to fix a problem on the latest Macbook Pro data corruption issue.
The company said the 15-inch mid 2015 range Retina model is being affected, with data corruption occurring only in rare cases.
Apple is being urged by several Macbook owners to take action on stains that they claim are appearing on the retina screen of their laptops.
The affected users are starting to worry about the expensive service fees they should bear after the expiry of the protection plan or warranties of their Macbooks.
The 15-inch MacBook Pro has more than five million pixels with fourth-generation quad-core Intel Core i7 processor, features Iris Pro Graphics with 128MB of embedded memory.
Apple said the processors allow users make complex tasks quickly in professional apps such as Final Cut Pro X, due to speeds of up to 2.8GHz, 6MB of shared L3 cache, and turbo boost speeds of about 4.0GHz.
Earlier this year, Apple unveiled a MacBook Pro Repair Programme, which will feature free repairs of the malfunctioning systems, that include distorted video, no-video, or unexpected system restarts.
The affected MacBook Pro systems were sold between February 2011 and December 2013.
