The installation process is divided into several clear steps. Please ensure your Mac is running macOS 10.13 or later. The following guide is based on version v18.00.0.66.
Click the download link on this page to get the dmg image file. The file size is about 120MB. After downloading, find the file in the “Downloads” folder.
Double-click the dmg file to mount the image. The system will pop up an installer window. Please read the “Readme.txt” file first for precautions.
In the installer window, you will see the “UltraEdit” icon and the “Applications” folder icon. Simply drag the UltraEdit icon to the “Applications” folder on the right.
The system will prompt for an administrator password. This is standard macOS security verification. After entering the password, the file will be automatically copied to the Applications directory.
Open “Launchpad”, find the UltraEdit icon and click it. On first launch, the system may prompt “from an unidentified developer”. Select “Open” to proceed.
After entering the main interface, the software will ask whether to import previous settings. It is recommended to choose “Default Settings”, which can be customized later. Installation is now complete.
If you encounter a “damaged” prompt, go to “System Preferences – Security & Privacy – General” and allow installation from any source. This is macOS’s Gatekeeper mechanism.
If it won’t start after dragging, try restarting your Mac. This rarely happens and is usually related to system cache.

Mastering some advanced techniques can double your coding efficiency. The following content comes from experienced developers.
Hold the Alt key and drag the mouse to select text. This allows you to select a rectangular area instead of continuous lines. This feature is particularly suitable for batch modifying CSV files or aligning code.
Practical Case: Suppose you have a log file with 1000 lines of data, each line starting with a timestamp. Using column mode, you can select all timestamps at once and then delete or replace them with one click.
In “Preferences – Code Snippets”, you can add commonly used code blocks. For example, type “fori” and press Tab to automatically expand into a complete for loop template.
Practical Case: Front-end developers can create HTML structure templates. Type “html5” to automatically generate DOCTYPE, head, body and other basic tags. This is 10 times faster than manual input.
In “File – Open – FTP”, enter the server address and credentials. UltraEdit will open remote files like local files. After saving, it automatically uploads without manual synchronization.
Practical Case: Operations personnel need to urgently modify configuration files in the production environment. Directly edit via FTP
