I am trying to change screensavers on OSX machines. However, due to the work from home setup, I am looking for a way to do this via Terminal. Do you have any tips on how to automate it? Thanks in advance.
Take a look at the following question: How to change the the screensaver using terminal (without using Preference Panel)?
Maybe one of the existing answers can help you to archive your goal.
But this require to manipulate plist-files which can cause unwanted side effects. So be careful.
