The Messages app on Mac OS X helps users to communicate with their family and friends. There are times when someone sends you a message, which is either sensitive or simply not to be saved on your Mac OS X. Regardless of the reason, you have the option to delete particular messages from the conversation thread.
An important thing to be kept in mind while deleting a message is that the effects are limited to your computer. The opposite party still has the message on his system.
Now, as you have got an idea of how things work, you can proceed to check instructions on deleting particular messages from the conversation thread.
How to Delete Particular Messages from Messages App in Mac OS X
Step #1. Launch the Messages app, either by searching for it in Spotlight or you can use Launchpad as well.
Step #2. Now inside any conversation, click on the message you wish to delete. In order to delete multiple messages, simply press Command+click on messages one by one to select them.
Step #3. You can either right-click any message and select “Delete” or simply hit the “Delete” key on the keyboard.
Step #4. When prompted, confirm the operation by clicking on “Delete” on the popup.
