Ioquake3 failed to launch (mac os sera 10.12.6)

The post above you says what to do.

  • Install Xcode.
  • Open Xcode, agree to license and then close it.
  • Download ioquake3 source code ZIP. Click the zip in Finder to unzip it.
  • Open Terminal app. Run cd Downloads/ioq3-master in Terminal to change to directory containing the ioquake3 source code.
  • Then, still in the Terminal, run ./make-macosx.sh x86_64. It will compile ioquake3. You can close the Terminal when it’s finished.

There should be an ioquake3 app in Downloads/ioq3-master/build/release-darwin-x86_64. Move the ioquake3 app to a folder containing baseq3.

For example:

/Applications/ioquake3/ioquake3.app
/Applications/ioquake3/baseq3/pak0.pk3
/Applications/ioquake3/baseq3/pak1.pk3
/Applications/ioquake3/baseq3/pak2.pk3
/Applications/ioquake3/baseq3/pak3.pk3
/Applications/ioquake3/baseq3/pak4.pk3
/Applications/ioquake3/baseq3/pak5.pk3
/Applications/ioquake3/baseq3/pak6.pk3
/Applications/ioquake3/baseq3/pak7.pk3
/Applications/ioquake3/baseq3/pak8.pk3
