I finally got around to testing this on my two Mac-based Xy4 systems, one based on vDosPlus, the other on DOSBox-X. Both had AOT commented out in SETTINGS.DFL; When I uncommented that setting, and restarted each app, AUTOSAV1.TMP and AUTOSAV2.TMP were created as expected in the correct locations. I used the Find Any File utility to find filenames that started with �AUTOSAV� and ended with �.TMP�, searching within packages, and the files (created today) appeared. I don�t have any idea of why this isn�t working on your setup.
