Jon, About xattr under Monterey, enter the command: which xattr If the result is anything OTHER than /usr/bin/xattr then you somehow have a different version of the command on your system, possibly through something installed by homebrew if you use homebrew, otherwise baffling. Anyway, to get the result you want in Monterey, use the command /usr/bin/xattr -rc followed by a space, and drag the program into it. Ignore any error messages that say �No such file.� If that doesn�t work, then something is seriously wrong with your Monterey system. As for copying the clipboard, I�m afraid I either don�t know or don�t remember. Question to the list: what commands are used to copy to the Windows clipboard with DOSBox or vDosPlus under Windows? I think Carl�s ACOPY and APASTE are supposed to work in Windows, but they don�t in the Mac. If anyone has any insights, please let us know.
