1. 安装配置 mbpfan 风扇控制器: https://github.com/linux-on-mac/mbpfan
   mbpfan.service文件从github获取。

   sudo apt-get install mbpfan
   sudo cp mbpfan.service /etc/systemd/system/
   sudo systemctl enable mbpfan.service
   sudo systemctl daemon-reload
   sudo systemctl start mbpfan.service

2. “软件和更新”中启用附加驱动，使用专有驱动。

3. 安装最新的tlp电源管理。

   sudo apt install tlp
   sudo systemctl enable tlp.service
   sudo systemctl daemon-reload
   sudo systemctl start mbpfan.service
   sudo tlp start

macOS 10.14之后不支持交叉编译32位程序。退求其次，虚拟机装ubunut来解决问题。
ubunut 64系统，默认不带32相关头文件和库，需要

sudo apt-get install libc6-dev-i386
sudo apt-get install linux-libc-dev:i386

之后就能正确交叉编译了。

32位 luajit

D:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Auxiliary\Build\vcvars32.bat
msvcbuild.bat

64位 luajit

D:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Auxiliary\Build\vcvars64.bat
msvcbuild.bat gc64

源码修正

修改common/almalloc.cpp ，屏蔽下面的代码

//#define ALIGNED_ALLOC_AVAILABLE (__STDC_VERSION__ >= 201112L || __cplusplus >= 201703L)

aligned_alloc 在ios13支持，早期的iOS会crash
