Drag and drop the AVCHD file onto the desktop. You can do some of the later steps first then save onto the desktop/folder at the end but I anecdotally believe this to be quicker and it also means you can take your SD card out quicker.

2. Rename the AVCHD file

Rename the AVCHD file. The naming is probably unimportant to you unless you intend to keep individual files. Perhaps the date of recording might be useful. Otherwise a single letter does fine. 

3. Open up the folder then rename BDMV

Again, can be renamed anything you like.

4. Go to the “STREAM” folder and open the first video with QuickTime Player

It is important to drop the 2nd+ videos on the right side to make sure the combined videos work in the right order. 

6. Press done and export the video file

You can export the file in whichever setting you like. Then just rename and save the file as you would any other file on a Mac.

It will take time to export the video and potentially a minute or two to begin the exporting depending on your machine.

Then congratulations, you have combined an AVCHD video file.
