The PCBUSB-Library realizes an USB to CAN user-space driver under macOS for PCAN-USB interfaces from PEAK-System Technik, Darmstadt.
This Gist describes how to install the library.
First download the library either from the MacCAN homepage or from the GitHub repo.
If you encounter problems installing or using libPCBUSB.dylib on macOS Monterey (12.x) and/or Apple Silicon (M1 chip), this guide may help you isolate the problem.
To basically check whether the PCAN hardware runs on your Mac or is supported by the PCBUSB driver, you can try the PCBUSB-Utilities. The utilities can_test and can_moni are standalone programs that run in user space and do not require the PCBUSB dylib to be installed.
Download and unzip the artifact(s) from latest tag. Do not run the install.sh script. Instead, run the binaries directly in a terminal session. Type either can_test --help or can_moni --help to see all program options.
