To recover an emptied trash Mac, the most effective methods are: restoring with Time Machine in case it was set up before the deletion; verifying the availability of backups in the cloud (for instance iCloud) if you have been using it; or finally, utilizing reliable data recovery software to perform a thorough scan of your disk for lost files. In a situation where the files have only been recently deleted, and the storage space has not yet been overwritten, recovery software can be a viable option to get the lost photos, documents, videos, and other file formats back, even when the Trash has been ​‍​‌‍​‍‌​‍​‌‍​‍‌emptied.
