I sure did misunderstand the Hardened Runtime. THANK you for your informative reply. I don't need this for an application of my own. I want all applications I am running through my bash shell to be able to see DYLD_* variables from the environment. (currently make gives me this problem). I believe make was installed by homebrew. And I guess other applications, like cmake may also behave similarly. But I guess it is too much of a hassle for me to codesign each and every executable that may need to read DYLD_* variables. The hassle being that on each upgrade of make I need to do the codesigns again for each executable. Unless I do : find /usr/local/bin -type f -exec codesign -d -vvv --entitlements - \{\} \; which is like the nuclear option really. I guess I need to disable globally this Hardened Runtime by disabling SIP (which I have refrained from doing over the last 7 years). Any other options? (Do I need to make a new post?) THANK YOU
