Hi all, one student of mine asked me for a help with installation TeXlive (from http://www.tug.org/mactex/mactex-download.html) on her MacBook Air 16 with macOS Catalina. Despite the fact that the site states "All install packages are developer-signed and notarized by Apple.", she got: "Cannot be opened because its from unidentified developer, MacOS cannot verify that this app is free from malware." What could it be? I have got no experience with MacOS, so I would like to ask for some hints how we can fix it. Thanks in advance. Best wishes, Tomáš
