I have a routine that opens a file. I believe it was working OK but now it's giving 'Macintosh HD:Users:aprildu:downloads:myfile.csv' could not be found. I did a bit googling and it seems to be caused by Apple sandbox requirement. What should I do to fix it? Have tried to save both the macro file and the file to be opened in a designated folder but it didn't seem to work. Many thanks!
