Some 2015 13" MacBook Pro Users Complain About UI Lag [Mac Blog]
 

A limited but growing number of 2015 MacBook Pro users have turned to the MacRumors discussion forums with complaints about user interface lag on OS X Yosemite. The lag results in slow or choppy animations and graphics across multiple areas of OS X, including opening Mission Control or Launchpad, launching full-size applications, resizing ******* and scrolling through web pages.


A pair of threads related to the issue have received close to 200 replies and 20,000 views within the discussion forums, with some users that previously experienced UI lag offering advice on how to resolve the problem. One potential solution involves resetting the Mac's PRAM, while temporary workarounds listed include increasing contrast and reducing transparency under the Accessibility menu in System Preferences.

It is worth **ting that new Macs may experience slower performance after booting up for the first few times as the computer indexes. It is also recommended that affected users perform a clean installation of OS X Yosemite to ensure that the issues are **t the result of restoring from a backup. But the issues persist for some, with MacRumors forum member "cookies!" claiming that his 2015 MacBook Pro has "the most significant lag" of "any laptop on Yosemite" he's ever used.

"I k**w that Retina displays are taxing on GPUs, but the Intel 6000 ****** seems incapable of driving this display without extreme choppiness in Yosemite for a number of actions? Mission Control, switching between *******, opening new *******, etc," reads a post in the MacRumors forums. "This is the most significant lag I've experienced on any laptop on Yosemite. My old 2010 Macbook Pro 13" doesn't lag this bad on Yosemite."

While complaints of user interface lag have resurfaced following Apple's release of the 2015 MacBook Pro, similar issues have been reported in the Apple Support Communities, Reddit, Stack Exchange and MacRumors discussion forums by owners of 13" and 15" mid-2012 through mid-2014 Retina MacBook Pro models. The problems appear to be mainly limited to **tebooks running OS X Yosemite.http://rss.feedsportal.com/c/35070/f...1/sc/28/mf.gif
