Folks, AES Crypt for Mac was updated so that it will operate on both Intel and ARM-based Macs. When AES Crypt 4 was released, the initial version was built only for Arm processors, but there was quite a bit of demand for Intel, too. The GUI version will run on either processor. The command-line version is built specifically for either ARM or Intel, so if you want to use the command-line version, be sure to download the appropriate version. Paul
