I am doing dialectology, and I was trying to install QGIS 3.12 (and QGIS 3.10 before) to use it in my study. Every time I opened the software my Mac always showed this notification "QGIS3"QGIS 3.12 (QGIS3 QGIS3.10) can't be opened because Apple cannot check it for malicious software".
I also tried installing Python 3.8 hoping it would work, but it didn't and I received the same message above.
How can I install and use the software so that I can start learning the software?
