 MacBook Pro 2018 Performance Throttling Issues Fixed in macOS 10.13.6 Supplemental Update 

HIGHLIGHTS

  • Apple has released a macOS update
  • The update fixes performance throttling on MacBook Pro 2018 models
  • It is 1.31GB in size

 Apple has released a macOS High Sierra 10.13.6 Supplemental Update for all compatible 

 Mac devices. The company says that the latest update is specifically designed to improve 

 the "stability and reliability" of the updated MacBook Pro models that debuted earlier this

month. It is reported that the update fixes the CPU throttling seen on Intel Core i9-powered 

 MacBook Pro 2018 laptops that was speculated to be caused by a thermal issue. Apple says 

 the CPU throtling was caused by a missing piece of firmware code that affected the thermal 

 management system. YouTuber Dave Lee had first demonstrated the flaw in a video that 

 showed how the video editing on the Core i9 model of the MacBook Pro 2018 was taking 

 more time to render content compared to the Core i7 variant of the 2017 MacBook Pro. The 

 CPU clock speed was found to have been throttled, findings that had been confirmed by 

 multiple publications.
"The macOS High Sierra 10.13.6 Supplemental Update improves the stability and reliability 

 of MacBook Pro with Touch Bar (2018) computers and is recommended for all users,"Apple 

 has said on its support page.
An Apple spokesperson in a statement to CNet has additionally confirmed that the 

 latest macOSupdate comes after extensive performance testing and adds a digital key to the 

 firmware to fix the thermal management system and ultimately enhance the performance of 

 the new MacBook Pro models. "Following extensive performance testing under numerous 

 workloads,we've identified that there is a missing digital key in the firmware that impacts the 

 thermal management system and could drive clok speeds down under heavy thermal loads 

 on the new MacBook Pro. A bug fix is included in today's macOS High Sierra 10.13.6 

 Supplement Update and is recommended," the spokesperson said, adding that customers 

 can expect the new 15-inch MacBook Pro to be up to 70 percent faster, and the 13-inch 

 MacBook Pro with Touch Bar to be up to 2x faster, as shown in the performance results on 

 Apple's website. The CPU throttling issue affects both new 15-inch and 13-inch MacBook 

 Pro 2018 models, CNet notes
As demonstrated by YouTuber Lee, while the Core i7-powered 2017 MacBook Pro model 

 had taken 35 minutes and 22 seconds to render a clip, the Core i9-backed 2018 MacBook 

 Pro had taken about 39 minutes and 37 seconds to render the same file. This was 

 apparently due to the thermal management bug that was restricting system performance on 

 the new models."This MacBook can't even maintain the base clock speed. Forgot about the 

 Turbo [Boost] and all that stuff, it can't even maintain the base clock of 2.9[GHz], which is 

 absurd," Lee had said in the video
Notably,Apple issued the latest macOS update less than two weeks after launching the new 

 MacBook Pro models. The security content of the new update is yet to be revealed on the 

 Apple support site.
