With strangling Apple has his experiences. Only the iPhone with a bad battery, now the new MacBook Pro 2018 with i9. A software update is to disable the limitation on the Macbook Pro.
The Apple Patch is called High Sierra 10.13.6 Supplemental Update and is to lift the limitation of the i9 in the new MacBook Pro. Until now, the firmware has missed a key, without which the thermal management has not worked properly, which causes performance problems.
In fact, the i9 in the notebook will not be demoted after the update. With the fix Apple had responded to reports that the Intel Core i9 processor can not develop its full performance due to thermal issues in the current MacBook Pro. The loss due to processor limitation is now to eliminate the additional MacOS High Sierra 10.13.6 update, which is now distributed through the Mac App Store.
Various tests have revealed that the Intel Core i9 processor in the current MacBook Pro support offers almost no advantage over the previous year's model with the Core i7 processor. Among other things, the MacBook Pro has recently reached its Turbo Boost speed shortly after the start of a benchmark. During operation – whether it is a benchmark or a video editing program – the frequency of the CPU is constantly lower than the standard clock of 2.9 GHz
The user David Lee even documented his tests in a video. In this one, it also shows that a cooled in the new MacBook Pro fridge very well under load also longer in turbo mode stays or does not fall immediately below 2.9 GHz. Then speculated Lee, housing and active cooling are not able to derive the resulting waste heat. The AppleInsider blog has also not ruled out this possibility according to its own tests too.
Apple mentioned in the discussion with CNET however another cause of the unexpected performance limitation. "After many performance tests under various workloads, we discovered that it was missing a digital key in the firmware that could affect the thermal management system and lower the frequencies under a high thermal load on the new MacBook Pro ", said a spokesman.
