MacOS Sierra update fixes MacBook Pro graphics issue and ditches “battery time remaining” estimate



Apple today is rolling out an update to macOS Sierra that addresses several issues with MacBook Pro computers, including the graphics problems on late 2016 MacBook Pro computers. Plus, in response to reported battery life concerns on these devices, Apple will now remove the “time remaining” display from the menu bar pulldown on the Mac, noting it was an inaccurate representation of how much battery life is left.

Additionally, the update changes the setup and opt-out experience for using iCloud Desktop and Documents – a feature that alarmed users by removing files from their desktop, when iCloud syncing was turned on.

Battery Life Issues

The most visible consumer-facing feature change is the removal of the battery’s “time remaining” display.

Battery life complaints have plagued the 2016 MacBook Pro devices, with users taking to Apple’s support communities and internet forums like Reddit to discuss the matter. While users in some cases reported they were only getting battery life of 3 to 6 hours, many were relying on the estimated battery life figures shown when clicking on the battery icon in the menu bar.

This estimation is not all that accurate, which is why Apple is removing it. The change seems like the sort of thing that’s only meant to silence the pesky complaints, but in reality, it’s fair to say that there are discrepancies between the estimations and actual battery life.

This is due to a number of factors. Apple’s newer Intel CPUs have dynamic power states, which means they can respond to calls from the OS with variable speeds, effectively eating up more or less juice from moment to moment. This ability to switch between low and high performance on the fly happens at the system level rapidly, and ultimately helps these machines save battery life by only using the power needed.

However, this switching between performance modes also impacts the system’s ability to provide an accurate battery life estimate. When you click to view the battery life estimate, the computer responds based on what you’re doing at the time. So, for example, if you were launching a program or opening up a big file, the time remaining would be low.

Other issues that affect battery life, especially on new computers where things are just being set up, include iCloud photo syncing and Spotlight search’s indexing of files.

We understand that Apple has actually examined the battery life data from installed systems, and found that battery life is behaving as expected.

In other words, the implication here is that the faulty battery life estimations are largely responsible for the bad reports. But it’s unclear what proportion of consumers’ complaints were based on real-world tests that took place after the initial setup period where Spotlight search and other background tasks have been completed, versus how many were based on simply looking at the battery life indicator.

Graphics Problems 

Another significant fix in the new update addresses the graphics issues on MacBook Pro models. Some users were affected by “flickering, full-screen checkerboard patterns, screen tearing, and other visual artifacts,” MacRumors had reported earlier this month, describing the problem.
