In an update to its original MacBook Pro evaluation, Consumer Reports has recommended laptops running a macOS 10.12.3 beta as the battery life issue has been fixed.

Consumer Reports recommended MacBook Pro laptops after finishing retesting of the laptops following software update by Apple, the Cupertino-based manufacturer of the machines.

In the update, the publication said, "With the updated software, the three MacBook Pros in our labs all performed well, with one model running 18.75 hours on a charge. We tested each model multiple times using the new software, following the same protocol we apply to hundreds of laptops every year."

Apple said in a statement that the laptop series used by the consumer product testing agency were found suffering a software bug in the Safari browser, which caused battery irregularities.

Wild fluctuations in battery life of the new laptops, both with and without Touch Bar, were found during multiple tests. Battery runtimes vacillated from 16 hours in one test to less than four hours in another.

Apple worked closely with the testing agency to identify the issue. After finding that a software bug was causing the issue, the tech giant successfully fixed it.
