For Windows we have Remote Desktop software which is already installed in the OS. For Mac we can use VNC Viewer to remote Raspberry Pi. Normally when we talk about PC remote, we need network either WiFi or LAN. For Raspberry Pi Zero/W/WH, we can use OTG USB as a local network to PC/Mac.
Previously, I have cover the same tutorial for Windows, you can refer to Getting Started with Raspberry Pi Zero W. Same concept applied to Mac, just different on the software. FYI, VNC Viewer also compatible with Windows, Linux, Android, iOS, and more. So, for Windows user, we advise to use VNC Viewer too.
