macOS Mail does not recognize Photoshop .psd file attachments
This is not a question; just an FYI... In the current macOS Monterey version 12.6.2, the Mail app does not recognize Photoshop .psd files sent as email attachments. Instead of the file name of the attachment displaying as xxxx.psd, a question mark icon appears in its place. When the attachment is clicked on, it does open correctly, however.
On the other hand, in the current iOS version 16.2, the Mail app DOES recognize Photoshop .psd files sent as email attachments, and displays them correctly as xxxx.psd.
So the macOS Mail app needs to be updated to recognize .psd files. I have submitted this bug to Apple Feedback.
