I have a new iMac and converted all my files from a MacBook. There are a number of docs I created on the Appleworks applications that I need to access. I am looking for a way to recover those files.
Yes, LibreOffice will open AppleWorks files (CWK extension).
See Supported file formats here: LibreOffice - Wikipedia
It will not save to that format. But it will enable you to open your files and then save them in the open document format used by LibreOffice.
