[Abstract] In the beta version of macOS Sierra released recently, the media discovered clues about the new MacBook Pro models. Tencent Digital (Shawn) Apple will basically upgrade its MacBook product line every year, even though the upgrade rate may not be large. In the latest release of macOS 10.12.4 beta, we saw some information on the next hardware upgrade of MacBook Pro. Technology blog Pike's Universum has discovered that the macOS Sierra beta contains three motherboard identifiers that are not currently part of any MacBook Pro model. Since these motherboards use the same processor management data as the 2016 MacBook Pro, it can be speculated that they should be prepared for the new upgrade of the series. The 2017 MacBook Pro is expected to use Intel’s faster, more efficient Kaby Lake processor. And more than a month ago, there has been news that this year's MacBook Pro will only usher in a slight increase in processing performance. The three new motherboard ids for macOS Sierra are: The Mac-B4831CEBD52A0C4C refers to two 13-inch non-Touch Bar versions of the MacBook Pro. The Kaby Lake processors they use support up to 3400MHz and 4000MHz respectively. The Mac-CAD6701F7CEA0921 should refer to three 13-inch Touch Bar models. They can support up to 3500MHz, 3700MHz and 4000MHz Turbo. The Mac-551B86E5744E2388 refers to three 15-inch Touch Bar models. Their highest Turbo frequency can reach 3800MHz, 3700MHz and 4100MHz respectively. Pike's Universum noted that after reviewing the performance preferences of the three motherboards, they concluded that they should not be prepared for desktop PCs such as the iMac and Mac Pro. In addition, they did not find any graphics data. After using these identifiers in comparison with Intel's current Kaby Lake processor family, this site lists the processor models that these upgraded models may use. 13-inch MacBook Pro (without Touch Bar) Intel Core i5-6360U 2.0 GHz (Maximum Turbo 3.1 GHz) and Iris Graphics 540 (15W) will be replaced with: Intel Core i5-7260U 2.2GHz (Max Turbo 3.4 GHz) and Iris Plus Graphics 640 (15W) Intel Core i7-6660U 2.4 GHz (Maximum Core 3.4 GHz) and Iris Graphics 540 (15W) will be replaced with: Intel Core i7-7660U 2.5 GHz (Max Turbo 4.0 GHz) and Iris Plus Graphics 640 (15W) 13-inch MacBook Pro (Touch Bar) The Intel Core i5-6267U 2.9 GHz (Maximum Core 3.3 GHz) and Iris Graphics 550 (28W) will be replaced with: Intel Core i5-7267U 3.1 GHz (Maximum Core 3.5 GHz) and Iris Plus Graphics 650 (28W) Intel Core i5-6287U 3.1 GHz (Maximum Core 3.5 GHz) and Iris Graphics 550 (28W) will be replaced with: Intel Core i5-7287U 3.3 GHz (Max Core 3.7 GHz) and Iris Plus Graphics 650 (28W) Intel Core i7-6567U 3.3 GHz (Maximum Turbo 3.6 GHz) and Iris Graphics 550 (28W) will be replaced with: Intel Core i7-7567U 3.5 GHz (Max Turbo 4.0 GHz) and Iris Plus Graphics 650 (28W) 15-inch MacBook Pro (Touch Bar) Intel Core i7-6700HQ 2.6 GHz (Maximum Core 3.5 GHz) and HD Graphics 530 (45W) will be replaced with: Intel Core i7-7700HQ 2.8 GHz (Maximum Core 3.8 GHz) and HD Graphics 630 (45W) Intel Core i7-6820HQ 2.7 GHz (Maximum Core 3.6 GHz) and HD Graphics 530 (45W) will be replaced with: Intel Core i7-7820HQ 2.9 GHz (Maximum Core 3.9 GHz) and HD Graphics 630 (45W) The Intel Core i7-6920HQ 2.9 GHz (Maximum Core 3.8 GHz) and HD Graphics 530 (45W) will be replaced with: Intel Core i7-7920HQ 3.1 GHz (Max Turbo 4.1 GHz) and HD Graphics 630 (45W) Apple introduced the first test version of macOS 10.12.4 to developers on January 24th, and will also release more test versions in the future. To be sure, it is unlikely that Apple will launch an upgraded version of the MacBook Pro before the release of this version, which will have to wait until the end of the month or early next month. Considering that MacBook Pro last upgraded less than 4 months ago, Apple should not release these new models immediately after the official release of macOS 10.12.4, but it is more likely to wait until June this year for WWDC. However, there are also news that the upgrade of the MacBook Pro will come later this year. KGI analyst Guo Mingqi said last month that the MacBook Pro equipped with Kaby Lake will be put into volume production in the third quarter of this year. He also mentioned that the "15-inch MacBook" will have 32GB RAM and will be put into mass production at the beginning of the fourth quarter. Source: MacRumors Wonderful video recommendations
