This worked to eventually select photos on my camera and send them to my Mac:
## Set up your Mac first:
1. Select or create the folder you want to share with your Lumix ZS30 camera.
2. In the Finder, open the Info window of that folder.
- Check the “Shared folder” box.
- Change everyone permissions to “Write only (Drop Box)”
3. Go to System Preferences… > Sharing
- Check the “File Sharing” box
- Make sure the computer name is not too long.
- Click the “Options…” button
- Check the “Share files and folders using SMB (Windows)” box
- Check the account for which you want to enable file sharing using SMB
- Click the “Done” button
4. Go to System Preferences… > Network
- The Wi-Fi service should already be selected.
- Check the “Show Wi-Fi status in menu bar” box
- Click the “Advanced…” button
- Select the “WINS” tab:
- The NetBIOS Name is the computer name as it should be written later on your camera
- The workgroup name should be WORKGROUP
5. Quit the System Preferences…
## On your Camera
Wi-Fi > New Connection > Send images Stored in the Camera > PC > Direct > Manual Connection
## On your Mac
- Select the camera SSID from your Wi-Fi menu.
- If necessary, enter the password displayed on your camera.
## On your camera
1. The “Connection successful” message should appear briefly.
2. When you see “Searching…”, click on the MENU/SET button.
3. Replace “Manual Input” with your computer NetBIOS name (see above).
4. Select the shared folder.
5. Enter your computer user account name and password.
6. Click on EXIT.
You should now see “WI-Fi connection completed”
The rest should be easy…
**EXTREMELY IMPORTANT (if you don't want to repeat all the above steps again):**
- Select Wi-Fi > History Connection
- Select your last connexion and register it to Favorite
Good luck!
