-### Сборка на Apple silicon (M1, M2)
-
-Пакетный менеджер Homebrew, когда установлен на Apple silicon, [стал использовать другую домашнюю папку по умолчанию](https://github.com/Homebrew/brew/issues/9177), `/opt/homebrew` вместо `/usr/local`. В результате некоторые библиотеки перестали собираться автоматически.
-
-Касательно EMQX, сборка Erlang из исходного кода не найдёт библиотеку `unixodbc`, установленную с homebrew, без дополнительных действий:
-
-```bash
-brew install unixodbc kerl
-sudo ln -s $(realpath $(brew --prefix unixodbc)) /usr/local/odbc
-export CC="/usr/bin/gcc -I$(brew --prefix unixodbc)/include"
-export LDFLAGS="-L$(brew --prefix unixodbc)/lib"
-kerl build 24.3
-mkdir ~/.kerl/installations
-kerl install 24.3 ~/.kerl/installations/24.3
-. ~/.kerl/installations/24.3/activate
-```
-
-Дальше можно собирать emqx как обычно, с помощью `make`.

-### Building on Apple silicon (M1, M2)
-
-Homebrew on Apple silicon [changed default location of it's home directory](https://github.com/Homebrew/brew/issues/9177) from `/usr/local` to `/opt/homebrew` and as a result a few things broke in the process.
-
-Concerning EMQX, when you install `unixodbc` package (one of the dependencies) via Homebrew, and build Erlang/OTP  with [kerl](https://github.com/kerl/kerl), kerl will not be able to find `unixodbc`.
-
-Here is how to solve it:
-
-```bash
-brew install unixodbc kerl
-sudo ln -s $(realpath $(brew --prefix unixodbc)) /usr/local/odbc
-export CC="/usr/bin/gcc -I$(brew --prefix unixodbc)/include"
-export LDFLAGS="-L$(brew --prefix unixodbc)/lib"
-kerl build 24.3
-mkdir ~/.kerl/installations
-kerl install 24.3 ~/.kerl/installations/24.3
-. ~/.kerl/installations/24.3/activate
-```
-
-Then you can proceed with `make`.
