macOS Printing Service Restart
Print Spooler Fix
Print Spooler Fix is a minimal shell script that restarts the macOS CUPS printing daemon when printing is stuck or the spooler needs a quick service reset.
Installation
Using the Melding Software Mac installer
Copy and paste this command into Terminal to install the Melding Software Mac scripts.
After reopening Terminal, type MeldingSoftware anytime to load the list.
curl -fsSL https://raw.githubusercontent.com/MeldingSoftware/Scripts/main/Mac/install.sh | bash
Because this command downloads and immediately runs a shell installer, you can review install.sh in the GitHub repository before executing it. Individual scripts may also request permissions, administrator access, Keychain authorization, Full Disk Access, or other macOS approvals depending on what the selected tool needs.
