Any preferences which can be set within Geneious Prime can also be set from the geneious.properties ﬁle which can be found in the Geneious Prime installation directory. On MacOS this ﬁle is located in Geneious.app/Contents/Java (R9 and above), or Geneious.app/Contents/Resources/app (R8 and earlier).
Some examples are present in the ﬁle already- remove the hashes from the start of the lines and modify the values to use them. If you need to ﬁnd out how to set other preferences using this ﬁle, please use the Support button in the Geneious toolbar to request help.
It is also possible to turn oﬀ access to all external services by editing this ﬁle (this is not possible via the preferences inside Geneious). This includes access to NCBI, Uniprot, Geneious plugin download, submission of error reports, support requests and usage tracking.
