After MacOS upgrade to Big Sur and having made changes to 'netbeansjdkhome' into the netbeans.conf file, the application is opened and running but it is NOT possible to open any of my projects because the box with my project files under "Documents" shows empty content (and of course my files are present there). Nor is it possible to create a new project, here some log messages: cd /Users/bparis/Documents/Netbeans; JAVAHOME=/Library/Java/JavaVirtualMachines/jdk-15.0.1.jdk/Contents/Home "/Applications/NetBeans/Apache .... shell-init: error retrieving current directory: getcwd: cannot access parent directories: Operation not permitted pwd: error retrieving current directory: getcwd: cannot access parent directories: Operation not permitted pwd: error retrieving current directory: getcwd: cannot access parent directories: Operation not permitted chdir: error retrieving current directory: getcwd: cannot access parent directories: Operation not permitted chdir: error retrieving current directory: getcwd: cannot access parent directories: Operation not permitted Scanning for projects... Same issue with Apache NetBeans 11.2 and 12.2. So I suppose Netbeans is not allowed to access files on disk. I went into my "System > Preferences > Security and Privacy" to try to change that behavior but Netbeans is not being listed and I can't add it" ("+" button not activated). I can give Netbeans the permission "Full access" to disk but that does no change. Thanks for any help, Bernard
