I updated the wiki page for installing LuaMetaTeX on MacOS:
Thank you for the wiki. It explains the complicate processes well.
As I wrote in the last mail, I don’t have a problem of installation as before. At this time, I don’t need to change SIP and the options of Gatekeeper in Mac OSX Catalina. Since I downloaded “install.sh”, it is inexecutable at the first time. But it worked well after allowing its running in the preference>security tab once.
I don’t know why there is no problem at all as before. There may be some changes in the new beta. For test, I installed the new beta once more and confirmed that it is installed well and running well.
However, your description is very useful when “install.sh” needs a permission of execution again and again.
Thank you for your helpful advice again.
