Installing the SWS Extension (for end users)

Make sure you download the correct architecture matching your REAPER version (32/64-bit, x86/ARM).

Linux

Extract the archive in your REAPER resource folder (Options > Show REAPER resource path in explorer/finder). That's ~/.config/REAPER for a non-portable install.

tar -xf sws-2.12.1.3-Linux-aarch64.tar.xz -C ~/.config/REAPER

macOS

Since the SWS Extension is not codesigned nor notarized, users of macOS Catalina or newer need to click on "Allow Anyway" in System Preferences > Security & Privacy after launching REAPER once for SWS to load when installed for the first time.

This can also be done manually by running this command from Terminal.app:

xattr -d com.apple.quarantine ~/Library/Application\ Support/REAPER/UserPlugins/reaper_sws_*.dylib  

Windows

Launch the SWS Extension installer and choose your REAPER install directory.
