How to Clear a Chat Transcript in Messages for Mac OS X
Want to quickly delete a Messages conversation on Mac? The Mac Messages app maintains a transcript of conversations that have been carried out on the computer, thus when you open a message window to a particular sender, you’ll see the prior conversations, pictures, and other sent/received data in the same message thread. If you’d like to clear out these conversations transcripts and related media, you can quickly do that without having to clear all Messages app chat history logs from the entire application.








If you’ve ever hit “Send” on an iMessage or text message that you wish you could take back, or perhaps you’d just like to cancel a sent picture because it’s stuck on ‘Sending’ and taking forever to send the message due to a congested network connection, then you may find this iPhone “cancel send” trick to be handy.
