# How to build ClickHouse on Mac OS X
Build should work on Mac OS X 10.12. If you're using earlier version, you can try to build ClickHouse using Gentoo Prefix and clang sl in this instruction.
With appropriate changes, it should also work on any other Linux distribution.
## Install Homebrew
```bash
/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
```
## Install required compilers, tools, and libraries
```bash
brew install cmake ninja gcc icu4c mysql openssl unixodbc libtool gettext readline
```
## Checkout ClickHouse sources
To get the latest stable version:
```bash
git clone -b stable --recursive --depth=10 git@github.com:yandex/ClickHouse.git
# or: git clone -b stable --recursive --depth=10 https://github.com/yandex/ClickHouse.git
cd ClickHouse
```
For development, switch to the `master` branch.
For the latest release candidate, switch to the `testing` branch.
## Build ClickHouse
```bash
mkdir build
cd build
cmake .. -DCMAKE_CXX_COMPILER=`which g++-8` -DCMAKE_C_COMPILER=`which gcc-8`
ninja
cd ..
```
## Caveats
If you intend to run clickhouse-server, make sure to increase the system's maxfiles variable.

Note: you'll need to use sudo.

To do so, create the following file:
/Library/LaunchDaemons/limit.maxfiles.plist:
``` xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN"
"http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
<key>Label</key>
<string>limit.maxfiles</string>
<key>ProgramArguments</key>
<array>
<string>launchctl</string>
<string>limit</string>
<string>maxfiles</string>
<string>524288</string>
<string>524288</string>
</array>
<key>RunAtLoad</key>
<true/>
<key>ServiceIPC</key>
<false/>
</dict>
</plist>
```
Execute the following command:
``` bash
$ sudo chown root:wheel /Library/LaunchDaemons/limit.maxfiles.plist
```
Reboot.
To check if it's working, you can use `ulimit -n` command.
