I'm missing Processing toolbox in my QGIS 3.4 (Mac-version). I know the feature can be activated when going to the Plugins and clicking it on, but it's not there.

    Have you try to reinstall QGIS ? You can install QGIS with OSGeo4W installer or by the independant installer: qgis.org/fr/site/forusers/download.html Jan 15, 2020 at 8:50
  • In QGIS 3 the processing toolbox is in the main menu item "Processing" docs.qgis.org/3.4/en/docs/user_manual/introduction/… but I suppose that you are missing that as well.

    OH YES, I did reinstall it from here kyngchaos.com/software/qgis Thank you so much Vincent!!!!! The key was this: OS X security may block installation, as I’m not an “identified developer” (ie not paying Apple to develop software). There a simple way to force it to install – right-click the installer file and select Open, this will trigger an extra option in the security warning to install it anyways. Jan 15, 2020 at 9:30
  • Please write that as an answer.

  • I believe that the new macOS Qgis versions from the Qgis site are now signed.
