For converting VCF to CSV on Mac using Google Contacts, follow these steps:

1. Open your web browser and go to https://contacts.google.com/.
2. Sign in to your Gmail account using your credentials.
3. Click on "Create contact" located in the upper-right corner of the screen, and then select "Create multiple contacts" from the drop-down menu.
4. Click on "Import" to open the import contacts window.
5. Click on "Select file" and navigate to the location where your VCF file is stored. Select the VCF file you want to convert and click "Import."
6. Once the contacts are imported, go to the left sidebar and click on "Gmail Labels."
7. Select the group labeled "Imported on [the date]" to view the imported contacts.
8. Press and hold the "Ctrl" key on your keyboard and select all the contacts you want to convert to CSV.
9. Click on the three-dot icon located in the upper-right corner and select "Export" from the drop-down menu.
10. Choose either "Google CSV" or "Outlook CSV" as the target format for the exported file. Select the desired format and click "Export."
11. Save the exported CSV file to your desired location on your Mac.

After completing the conversion, you can return to Google Contacts and delete the imported contacts to avoid mixing them up with your existing contacts. It's worth noting that you should convert fewer than 3,000 contacts at a time to avoid encountering any issues during the conversion process.
