Default FTP Client
Tells the OS which application to to use when opening FTP connections, for example when you click on a link like ftp://email@example.com. By default, this is set to the Finder.
Windows Open With
Determines which remote or local panes will appear in new Transmit windows. The default setting puts a local pane with your Home folder on the left and a blank Remote pane on the right. If you set either pane to use one of your saved Servers, check the box labeled Connect to Server on Startup to automatically open a connection to this server on launch.
File Editor Font
Specifies the typeface used when editing files in Transmit’s built-in editor.
Show Transmit Disk in Menu Bar
Check this box if you’d like to access Transmit Disks from your Mac’s menu bar.
Determines whether or not crash reports and anonymous usage data are sent to Panic. Read a clear, simple explanation of exactly what is sent – and why – on our website.
Transmit has built-in automatic software updates. Choose one of three options:
- Automatically download and install
- Updates will be downloaded in the background, as you work, as they become available. You will be prompted to relaunch Transmit when the update is ready to be installed.
- Just notify if there are updates
- Select this to be prompted when a new update is available. You will be able to choose whether to install it right away, be reminded later, or skip this particular update altogether.
- Don’t check for updates
- Transmit will not check for available updates. (Not recommended!) To install newly released updates with enhancements, bug fixes, and important security patches, you can manually download the latest version from our website.
Panic Sync is a free, secure, purpose-built way to sync your Servers, keys, and passwords.

Ask before deleting items
Check this box to be prompted before a local item is sent to the Trash, or a remote item is deleted forever.
Double Click Action
Determines what happens when you double-click on a file.
Keyboard Cowboys: You can hit Command+DownArrow to perform a double-click action on the selected item. (This works in the Finder, too!)
You can use this setting to associate external applications with a particular file type. Custom editors appear in the contextual menu when right-clicking on a file, and will be used when the Double Click Action is set to Edit in External Editor.
When An Item Already Exists…
Use these settings to tell Transmit what to do when transferring an item to a location where an item with that same name already exists. By default, Transmit will ask you what to do whenever these situations arise.
Replace means delete the item in the destination and replace it with the item being transferred.
Merge means the contents of the source and destination folders will be compared, existing items overwritten, new items uploaded, and items no longer existing in the source folder are left in place in the destination.
Resume will attempt to finish a partially-transferred file. This is not supported by every protocol or every server.
Be careful about replacing and merging folders. Replacing a folder might accidentally cause you to lose some data if you’re expecting the files in the two folders to be Merged.
Limit the total bandwidth used by uploading and downloading in Transmit.
If you have a relatively fast network connection (above 1 MB/sec), these setting can be unreliable, and should be avoided.
Transfer up to ___ files simultaneously
The number of items in the transfer queue that are actively transferring at any given time.
Need to limit the number of simultaneous connections to your server? Head to the Advanced Preferences.
- Use passive (PASV) mode for data transfers
- Check this box to use Passive mode by default for FTP transfers. Note that each of your saved Servers has a setting for this that will override this global setting.
- Play alert sound
- Select the sound that will play (if any) when Transmit needs to get your attention.
- Open files after downloading
- Enable this setting to automatically open files once they finish downloading.
- Remove activity Items
- Choose whether items in the transfer queue should be automatically removed when they successfully complete, or persist until you remove them manually.
FTP ASCII File Extensions
Items with these file extensions will be transferred using FTP’s ASCII mode. If an extension is not on this list, it will be transferred in Binary mode.
Custom Cloud Server Upload Headers
- When checked, the custom headers will be set when a file is uploaded. You can use the checkbox to quickly enable and disable the setting of specific headers without having to delete and recreate them.
- Your custom headers will be applied when uploading files with this file extension (for example,
.html). To apply custom headers to all uploads, select Default.
- The name of the header (for example,
- The value to set for this header (for example,
File Rules are applied to folder listings and Synchronize operations. Items matching a Rule’s conditions can be skipped in file transfers, hidden from file listings, or invisible items shown without showing all invisible items.
Click the button at the bottom of the File Rules panel to add a new rule. A checkbox to the left of a rule’s name indicates whether the rule is currently being applied to folder listings. To make a rule that is applied to Synchronize operations but not general file listings, leave this box un-checked.
Using the dropdown menu to the right of the rule’s name, choose what will happen to items matching the condition of this rule: Skip, Show, or Hide.
Add one or more conditions to define your rule.
Regex Nerds! File rules support regular expressions. To add a regex condition, choose the field to match against (Name, Path, Date, Size, Kind), then choose matches, and enter your regex in the text field.
By default, Transmit lets the server determine the permissions of files it uploads. If necessary – and if your server supports it – Transmit can be configured to explicitly set permissions by kind and protocol.
To enable explicit permissions setting, check the box next to a file extension. Default File and Default Folder apply to all files and all folders, respectively. Click the button below the panel to add a new kind of file to the list.
Click through each of the protocols to see what permissions will be set when uploading. Make changes as necessary.
Transmit supports SSH keys for SFTP connections. Keys in this list can be used to connect to your servers, and if Panic Sync is enabled, they will be synced to your other devices.
To add a key to the list, click the at the bottom of the panel. To add an existing key, choose Import. To create a new key, choose Generate.
If you need to connect to your server through a proxy, enter the connection details here. Otherwise, leave these settings untouched.
- Try to Keep Idle Connections Alive
- If enabled, Transmit will periodically send a simple command to prevent the connection from being closed.
Advanced Server Settings
FTP isn’t a strictly-defined standard, so not all FTP servers work the same way. Use these settings to apply special case settings to individual servers.
- Server List
- The server these settings will apply to. Default means all FTP servers. Click the button at the bottom of the list to add a new server.

- Use PRET command
- Use the PRE Transfer command
- Use TLS v1.2 encryption
