LyX start every time as a new application I use LyX and I installed last version 2.3.5.2 on macOS Catalina 10.15.7.
Whenever I launch the application the system shows a progress bar saying 'Verifico &quot;Lyx.app&quot;...' (this is Italian, in English it should read something like 'Verifying &quot;Lyx.app&quot;...' or 'Checking &quot;Lyx.app&quot;...').
After that a window pops-up saying '&quot;Lyx.app&quot; è un'applicazione scaricata da internet. Confermi di volerla aprire?' (that translated is '&quot;Lyx.app&quot; is an application downloaded from internet. Do you confirm you want to open it?'), and I answer &quot;yes&quot;.
This behavior is OK for the first run, but it repeats every time I launch the application, and seems more a problem of macOS than a problem of Lyx. Can someone help?
I finally realized that the folder /Applications/LyX.app/ didn't have write permissions not even for the proprietary user, differently from all other *.app folders in /Applications, so the execution of the command
chmod +w /Applications/LyX.app

solved the problem.
