At the beginning of 2018, I bought a second-hand Lenovo ThinkPad 11e laptop for 799 yuan on the Xianyu app. This is an American version of an educational computer with a relatively new condition. According to the built-in hard disk record, the computer has only been used for 230+ hours. The appearance adopts a plastic structure with anti-collision bars, and the screws at the bottom are removed. Although the memory bars have been welded to the motherboard, hardware modules such as wireless network cards and hard disks can be replaced. The best thing is that some netizens released the black Apple Clover EFI boot package based on the MacOS High Sierra 10.13 system.
At that time, I successfully started the black apple according to the netizen’s black apple Clover EFI boot package, but because of my poor skills, the notebook touchpad could not be driven, the Fn key could not be used to adjust the screen brightness, and the system was running slightly stuck. Dayton and so on. Because there is a certain gap between the experience and the white apple, and I am unable to solve it, this black apple laptop is gradually eating ashes.
Recently, when I was sorting out old things, I found this idle laptop. Based on the principle of waste utilization, I have carried out certain software and hardware transformations on it, and successfully run the black apple macOS Catalina on the ThinkPad 11e.
Notebook configuration list:
CPU : Intel Core M 5Y10c (800 MHz main frequency, 2.00 GHz turbo frequency, 4M cache, TDP 4.5 W)
Memory : 4G DDR3L 1600 MHz SDRAM (dual channel memory onboard, not replaceable)
Graphics : Intel HD Graphics 5300
Screen : 11.6-inch LED backlight (resolution 1366×768)
Sound Card : Realtek ALC283
hard drive :
320 GB 7200 rpm(replaced with Crucial BX300 240G SSD)Wired network card : Realtek RTL8111GUS-CG
Wi-Fi :
Intel Dual Band Wireless-AC 7265– M.2 2230 interface (replaced with Apple’s original DW1820A/BCM94350ZAE, 802.11ac dual-band, support 2.4GHz/5GHz, 867Mbps)Bluetooth :
Bluetooth 4.0(replaced with Bluetooth 4.1)Others : USB 3.0 ×1/USB 2.0 ×1/HDMI ×1/LAN/headphone jack/four-in-one card reader (SD Card, MultiMediaCard, SDHC Card, SDXC Card)
The machine configuration is similar to the White Apple A1534 (12-inch MacBook released in 2015): there are three A1534 models, and the CPUs are M-5Y31, M-5Y70, and M-5Y71. Among them, this model is the closest to the M-5Y31 hardware architecture, the integrated graphics card model is the same, and the system can be adapted to the Big Sur 11.0 system at most.
According to the feedback from netizens, the MacOS Catalina 10.15.7 system is more smooth than the Big Sur 11.0 system and higher systems when using the older Intel platform black Apple computer. Based on the Clover EFI boot package of the High Sierra system, I replaced and simplified some files, and paid someone to modify the DSDT file, which perfectly realized 95% of the functions of the white apple. Lightweight tasks such as surfing the Internet, writing blogs, listening to songs, and playing online streaming media run smoothly.

With Apple’s announcement in mid-2020 that it will fully switch to Apple Silicon architecture chips, this move will make it impossible for hackers to use the latest version of macOS in a few years. Black apples, use and cherish!
