help I have no idea what I'm doing. I wanted a photo editing software on my MacBook Pro running big sir. I came across gimp and it suggested I install it using macports. I ran the macports installer without knowing I was supposed to install Xcode first and now I don't know what that would have done to my computer since as far as I know I don't have Xcode. I want a do over. How do I find and remove whatever the macports installer would have put on my customer?
You can uninstall MacPorts using their official instructions:
sudo port -fp uninstall installed sudo dscl . -delete /Users/macports sudo dscl . -delete /Groups/macports sudo rm -rf \ /opt/local \ /Applications/DarwinPorts \ /Applications/MacPorts \ /Library/LaunchDaemons/org.macports.* \ /Library/Receipts/DarwinPorts*.pkg \ /Library/Receipts/MacPorts*.pkg \ /Library/StartupItems/DarwinPortsStartup \ /Library/Tcl/darwinports1.0 \ /Library/Tcl/macports1.0 \ ~/.macports
Now MacPorts is removed, you can install Gimp without MacPorts using a regular installer from their website: from https://www.gimp.org/, choose Download, then Download Directly.
