brew install git automake cmake wget pkg-config gnu-tar ninja nasm meson

sudo xcode-select -s /Applications/Xcode.app/Contents/Developer

git clone --recursive https://github.com/telegramdesktop/tdesktop.git
./tdesktop/Telegram/build/prepare/mac.sh

Building the project

Go to BuildPath/tdesktop/Telegram and run (using your api_id and api_hash)

./configure.sh -D TDESKTOP_API_ID=YOUR_API_ID -D TDESKTOP_API_HASH=YOUR_API_HASH
