English:

I'm tried boot to MacOS Catalina (10.15.3) and Big Sur (11.5.2) with your EFI for an almost equal Acer Model (TravelMate P246-MG), and all is working booting installer, at least until charge the System Image; later launch a Kernel Panic.

Maybe, this video will be a guide for seek the problem: https://youtu.be/gAPsP93HXQQ

Finally, I describe some interesting data from my Laptop:

Originally was a Acer Aspire E5-471G (with Intel i5 5200U and a Nvidia GT820M), but, had problems with voltages and Intel SoC died; I changed the Motherboard (buyed on AliExpress), and I received a TravelMate P246-MG Motherboard model (with Intel i7 5500U and the same Nvidia graphic card), practically is the same laptop, but, seems that in BIOS memory access are different.

If do you need more info from laptop:

Acer "TravelMate P246-MG"
SoC: Intel i7 5500U 2.2Ghz
iGPU: Intel HD Graphics 5500.
RAM: 4x2GB 1600Mhz DDR3 (by Kingston and Hynix).
BIOS/Motherboard Model: ZQ0B/G (not ZQ0A/D as E5-471).
WLAN Card: Intel AC 3160.
Ethernet: Realtek 81xx Series (8111, exactly).

中国人:

我尝试使用 EFI 启动到 MacOS Catalina (10.15.3) 和 Big Sur (11.5.2) 以获得几乎相同的 Acer 型号 (TravelMate P246-MG)，并且所有启动安装程序都在工作，至少在系统充电之前图片;稍后启动内核恐慌。

也许，这个视频将成为寻找问题的指南：https://youtu.be/gAPsP93HXQQ

最后，我描述了一些来自我的笔记本电脑的有趣数据：

原本是 Acer Aspire E5-471G（搭配 Intel i5 5200U 和 Nvidia GT820M），但电压有问题，Intel SoC 死机；我更换了主板（在速卖通上购买），收到了 TravelMate P246-MG 主板型号（带有 Intel i7 5500U 和相同的 Nvidia 显卡），实际上是同一台笔记本电脑，但是，似乎在 BIOS 内存访问中有所不同。

如果您需要来自笔记本电脑的更多信息：

宏碁“TravelMate P246-MG”
SoC：英特尔 i7 5500U 2.2Ghz
iGPU：英特尔高清显卡 5500。
RAM：4x2GB 1600Mhz DDR3（金士顿和海力士）。
BIOS/主板型号：ZQ0B/G（不是 E5-471 的 ZQ0A/D）。
WLAN 卡：英特尔 AC 3160。
以太网：Realtek 81xx 系列（确切地说是 8111）。

I have been removed all Broadcom kexts, but at trying boot to OC again, the error is the same, ACPI properties are lost.

I was fixed the boot and installation using the Aspire E5-573G OC EFI for Catalina 15.x (modifying a little bit the config.plist and using some Dell SSDTs), and almost all is working, but I wanna fix the audio card and the "Fn Shortcuts".

Here's my modified EFI if you wanna check some details: https://github.com/sebasrock156/Acer-TravelMate-P246-MG-OpenCore
