FTP From Mac: Connect, Transfer Files, and Stay Safe

Yes—you can use FTP from a Mac, but the built-in Finder does not provide a full FTP file-transfer client. For a reliable connection, use a dedicated client that supports FTP or, preferably, SFTP; you will need the server address and the login details supplied by its administrator.

FTP, SFTP, and FTPS: What’s the Difference?

FTP (File Transfer Protocol) is a long-established way to upload and download files between a computer and a server. A server may host a website, provide shared files, or belong to an organization. FTP is a protocol, not a particular app or a type of internet connection.

Three protocols are commonly confused:

FTP transfers files without encrypting the login credentials or data. Anyone able to observe the connection may be able to read them.
FTPS adds encryption using TLS. It is still FTP, with security negotiated as part of the connection.
SFTP transfers files over SSH. It is a separate protocol from FTP, even though its name includes “FTP.”

Use the protocol your server supports, and choose SFTP or FTPS when available. Do not assume that an FTP server will accept SFTP: the hostname, port, and account can be different.

What You Need Before Connecting

Ask the server administrator or hosting provider for the connection settings. “FTP details” alone may not be enough, since the client needs to know the protocol and where to connect.

Host: a domain name, such as files.example.com, or a server IP address.
Protocol: FTP, explicit or implicit FTPS, or SFTP. Follow the server’s instructions rather than guessing.
Port: often 21 for FTP or explicit FTPS and 22 for SFTP, but server settings can differ. Implicit FTPS commonly uses 990.
Username and password: some servers instead require an SSH key, or provide a special account or key file.
Remote folder: the starting directory, if the administrator specifies one.

A connection can fail even when the password is correct if the wrong protocol, port, host, or account type is selected. Store passwords only in a trusted client and follow your organization’s instructions for credentials and key files.

Connect From a Mac With a File-Transfer Client

A dedicated client gives you a server connection form and a view of local and remote files. The exact labels vary, but the process is generally similar:

Install a reputable file-transfer client from its official source. Check that it supports the protocol required by the server.
Open the client’s connection or site manager and create a new connection.
Enter the host, protocol, port, and username. Add the password or SSH key details only as required.
Connect. If the client displays a server host-key or certificate confirmation, verify it against information from the administrator when possible. Do not dismiss an unexpected warning without checking.
Browse to the correct remote directory. The client usually shows local files on one side and server files on the other.
Upload or download by selecting files and using the client’s transfer controls or drag-and-drop. Check the transfer queue and confirm that the operation completed.

Before uploading a large batch, transfer one test file and make sure it appears in the intended location. Be cautious when deleting or replacing remote files: a server folder may contain the live version of a site or shared work.

Can Finder Connect to an FTP Server?

Finder’s “Connect to Server” feature is often mentioned in older FTP instructions. In current macOS, Finder does not offer a full FTP client for browsing and transferring files. It can connect to some network file-sharing services, but that is not the same as general FTP support.

For ordinary FTP transfers, use a dedicated client. Finder can still be useful for managing files after they have been downloaded locally, and some third-party apps can integrate remote locations into file browsing. Their capabilities depend on the app and protocol; check that they support the server’s required connection type.

FTP vs. SFTP and Other Options

The right choice depends on what the server supports and what you need to do. For a one-time transfer, a web-based file manager or a shared cloud folder may be simpler if the service provides one. For repeated transfers, a client can save connection settings and make it easier to manage folders.

Choose SFTP when the server offers it and you need an encrypted file transfer over SSH.
Choose FTPS when the server specifically requires FTP with TLS encryption.
Use plain FTP only when required and when the data and connection are appropriate for an unencrypted protocol. Avoid sending sensitive information over it.
Consider a web interface or shared drive when you only need basic uploads and downloads and the service supports those options.

SFTP is not simply “FTP with security turned on.” It uses a different connection method, so an SFTP setting will not work against a server configured only for FTP or FTPS.

Common Connection Problems

If a connection fails, check the settings systematically before repeatedly changing the password:

Connection timed out: verify the hostname and port, check that the server is online, and ask whether your network or account must be allowed through a firewall.
Login rejected: confirm the username, password, and authentication method. Some servers require a key for SFTP and do not accept a password.
Protocol or handshake error: make sure the client is set to the server’s exact protocol, including the correct type of FTPS if applicable.
Login works but folders are missing: check the starting directory and account permissions. You may be restricted to a particular server folder.
Files appear to stall or listings fail: FTP can use separate control and data connections, and firewalls or network address translation can complicate the data connection. Ask the server administrator which transfer mode and settings to use.
Upload is denied: the account may not have write permission for that directory, or the server may impose file-type or storage restrictions.

When reporting a problem, provide the protocol, host, port, time of the attempt, and the client’s exact error message. Do not send a password in an email or support message.

Frequently Asked Questions

Does Mac have FTP built in?
Finder does not provide a full FTP client for general file transfers. Use a dedicated client that supports the protocol required by the server.

How do I FTP from a Mac?
Get the host, protocol, port, and account details, enter them in a compatible file-transfer client, connect, then transfer files between the local and remote views.

Is SFTP the same as FTP?
No. SFTP is a separate protocol that transfers files over SSH. FTP and FTPS use different connection methods, so the server and client must agree on the protocol.

Is FTP safe to use?
Plain FTP does not encrypt credentials or transferred files. Prefer SFTP or FTPS for an encrypted connection, and follow the server administrator’s guidance.

Why can I log in but not upload?
Your account may have read-only access or lack permission for the destination directory. Check the folder path and ask the administrator to confirm your access.
