If you want to save iCloud emails into a local drive on macOS with attachments, you can either use manual methods or a more automated approach. On macOS, you can configure your iCloud account in Apple Mail and export mailboxes, but this method can be slow and may not handle large volumes efficiently. In real-world scenarios, users often look for a faster and more reliable solution. For example, SysInfo iCloud Backup Tool is commonly used because it simplifies the process. After signing in, you can choose the emails you want, ensure attachments are included, and save everything directly to your system. The tool keeps the original structure intact, making it easier to manage and access emails later.
