By the looks of it, Apple may be having a new Chargegate on its hands. Several customers have determined their MacBook Pro has a habit of maxing out the CPU and overheating while charging the use of the left side ports.

On the official help page, Apple states that you may charge your MacBook Pro the use of either one of the USB-C ports. However, it seems that there are a right way and a wrong manner to fee your high-priced device, in particular in case you don’t want to see any performance impact.

The problem was observed numerous months in the past by means of a StackExchange consumer that pronounced seeing unusual hobby in Activity Monitor. Specifically, he noticed unusually excessive CPU utilization for a system called kernel_task, which caused high temperatures and reduced overall system overall performance – not to mention the truth that it keeps those tiny fanatics spinning on what should otherwise be an especially quiet machine.

If that wasn’t enough, restarting the MacBook in question might not remedy the problem, with the kernel_task method popping up once more as soon as macOS boots up. According to Apple, one of the capabilities of kernel_task is to manipulate your MacBook’s CPU temperature with the aid of intentionally making much less of it available for apps which are the use of it too intensely.

In this case, a cautious investigation discovered that having a peripheral plugged into one of the left-hand ports at the same time as a charger is hooked up to the opposite will increase the temperature of the MacBook case. Sensors that display the Thunderbolt ports appeared to verify this to be the case even supposing the CPU temperature would not warrant the throttling.

Luckily, there’s a simple way to this, and it is to price your MacBook the use of handiest the right-hand aspect ports while the usage of the left-hand side ones for peripherals. Another Stackexchange person said that this strategy could make bigger to plugging video display units on a different aspect because the charging cable to hold things cool on both sides of the chassis.

At this point, two models seem to be affected: the 15-inch MacBook Pro 2017 and the 16-inch MacBook Pro 2019. Apple has yet to touch upon the issue, but at least we recognize the employer is working to extend the lifespan of MacBook batteries through the following macOS Catalina update. Hopefully, it’s going to also consist of a repair for the heat issues associated with charging it using the left aspect ports.
