UltraEdit for Mac is an award-winning professional-grade text editor. With its clear interface layout and powerful project and workspace management features, it can easily handle complex software development projects. Despite its rich functionality, its highly customizable and elegant interface ensures intuitive access to core features, avoiding cumbersome and complicated operations. It is an efficient tool for developers and technical writers.
UltraEdit for Mac supports full theme customization. Users can choose built-in themes, download community-shared themes, or create their own themes entirely from scratch, making the editor truly match personal aesthetics and work habits for a highly personalized working environment.
It offers industry-leading and intuitive multi-cursor editing and multi-selection capabilities. After positioning the cursor or selecting text, you can copy, cut, paste, select, and delete just like regular editing, greatly improving efficiency in batch editing and code refactoring.
UltraEdit has a comprehensive and powerful search system that supports:
Access and edit files on remote servers through the built-in FTP browser or directly from the File View, enabling seamless management and synchronization of local and remote files. Convenient for website maintenance and server file editing.
In addition to regular horizontal editing, it offers a unique “Column Mode” that allows users to perform block editing vertically (along the Y-axis) anywhere in the document. This feature is especially useful for handling tabular data, aligning code, or batch modifying text columns.
The interface has been fully optimized for Retina and other ultra-high-definition (UHD/4K) displays, ensuring clear and detailed visual experiences on any high-resolution screen.
UltraEdit is designed for handling large files, capable of smoothly editing huge files (such as database files, log files, etc.) that cause other editors to crash. It is favored by professionals in data analysis and system management.
Available for Windows, Mac, and Linux, and compatible with a variety of mainstream and niche Linux distributions, ensuring users get a consistent and efficient editing experience across different operating systems.

The following screenshots show the main interface and core features of UltraEdit for Mac:

Main Interface: Clear layout, intuitive workspace management.

Multi-Cursor Editing: Edit multiple text locations simultaneously, boosting efficiency.

Theme Customization: Rich theme options to create a personalized working environment.

Column Mode Editing: Vertical selection and editing, handling column data with ease.
Step 1: After downloading, double-click the .dmg file to mount the disk image. The system will pop up an installer window containing the app icon and a shortcut to the Applications folder.
Step 2: Drag the UltraEdit icon to the Applications folder. This is the standard practice to ensure the app is installed in the system applications directory.
Step 3: On first launch, the system may prompt “Cannot verify developer.” Go to “System Preferences” > “Security & Privacy” > “General” and click “Open Anyway.”
Step 4: Enter the administrator password as prompted to complete authentication. The app will officially launch and enter the initial configuration interface.
Step 5: Select the interface theme and encoding preferences. For first-time users, it is recommended to choose the “Classic Dark Theme” to protect your eyesight, and keep the encoding format as the default UTF-8.
Step 6: Configure the workspace layout. Through the “Window” menu under “Workspace Layout,” select “Full-Featured Development” or “Lightweight Editing” mode.
Step 7: Set up the shortcut scheme. Go to “UltraEdit” > “Preferences” > “Key Mapping” to import or customize key combinations.
Step 8: Enable FTP/SFTP functionality. In the “File” menu, click “FTP Account Manager” to add the server address, port, username, and password.
Step 9: Test large file handling capability. Open a log file larger than 200MB and observe scrolling and search response speed to verify performance.
Step 10: After completing all settings, it is recommended to restart the app once to ensure the configuration takes full effect. At this point, installation and basic configuration are all complete.

Answer: This is because the macOS Gatekeeper security mechanism has blocked an unsigned application. Please go to “System Preferences” > “Security & Privacy” > “General” and click “Open Anyway.” If the option does not appear, try right-clicking the app icon and selecting “Open.”
Answer: Click the menu bar “Window” > “Workspace Layout” > “Reset to Default Layout.” This will restore all panel positions and visibility settings without affecting themes and shortcut configurations.
Answer: First, check whether the server address and port are correct. Then, in the “FTP Account Manager,” try changing the “Transfer Mode” from “Passive” to “Active,” or vice versa. If using SFTP, ensure the port is 22.
Answer: Press the Esc key to exit multi-cursor mode. Alternatively, left-click anywhere in the text, and the system will automatically cancel all extra cursors, keeping only the primary cursor.
Answer: UltraEdit supports importing .tmTheme files. Go to “Preferences” > “Themes” > “Import” and select your theme file. There are plenty of shared themes available for download on the community forum.
Answer: It is recommended to enable “Hardware Accelerated Scrolling” in “Preferences” > “Editor” > “Scrolling.” At the same time, turning off “Syntax Highlighting” and “Line Number Display” can significantly improve performance.
Answer: Configurations are stored in the com.ultraedit.plist file in the ~/Library/Preferences/ directory. Simply copy this file to complete the backup. After reinstalling the system, put it back in the original location to restore.
