Chiaki is a Free and Open Source Software Client for PlayStation 4 and PlayStation 5 Remote Play for Linux, FreeBSD, OpenBSD, Android, macOS, Windows, Nintendo Switch and potentially even more platforms.
This is a tiny fork of the Chiaki project. Its only improvement is support for the Touchpad button (i.e. deep-pressing on the touchpad on the PS4 controller). Previously, this was not supported, so one had to press "T" on the laptop keyboard to simulate a touchpad press. This was an inconvenience in games that used this button, such as Final Fantasy 7 Remake.
I've pre-built the Mac OSX binary and shared it on Google Drive.
You shouldn't trust pre-built binaries downloaded from a random source on the Internet. But since I found it fairly difficult to build Chiaki on OSX, I'm providing this binary for convenience.
