Software Update for 2018 MacBook Pro CPU Throttling Issue Released
Apple has released a bug fix software update for macOS High Sierra 10.13.6 aimed specifically at Mac users who own the latest 2018 model year MacBook Pro with the Touch Bar.
The update is labeled as “macOS High Sierra 10.13.6 Supplemental Update for MacBook Pro (2018)” and apparently aims to resolve a problem where the new MacBook Pro Touch Bar models were sometimes dramatically underperforming due to thermal issues with the processor, causing the CPU to throttle itself significantly. Installing the bug fix update should therefore resolve the performance issue.
