MacOS+TeXlive: installation problems

MacOS+TeXlive: installation problems

[Tomas Hala]

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

The solution is rather simple, check here:

For the first run, you need to 'deliberately' run the application rather than just double-clicking it or choosing from the Launcher. (This is intended to prevent people casually running anything they download from the Internet without thinking.)

To deliberately run the app, go to the Applications folder, option-click (aka right click) the TeXLive app and choose Open" from the contextual menu that pops up. You should then get a warning dialog asking if you really want to run the app. Agree and the app will open and the Mac should then remember so that next time a simple double-click will be sufficient.
