UltraEdit for Mac is a widely acclaimed professional text editor with over four million advanced users worldwide. Renowned for its exceptional flexibility, powerful features, and high security, it is recognized as an industry-leading text editing solution.
UltraEdit offers a range of advanced features designed to enhance coding and text processing efficiency.
Through code-aware and context-aware technology, it provides dynamic auto-completion suggestions. It supports most modern programming languages, can display class members, function hints, and other information, and allows users to configure it in-depth or minimally according to personal preference. Most importantly, all features work out of the box without relying on risky third-party plugins or complex configuration adjustments.
UltraEdit boasts the industry’s most powerful and intuitive multi-cursor editing and multi-selection capabilities. Users can edit at multiple locations simultaneously and perform copy, cut, paste, select, and delete operations as if working with a single selection.
View the rendered output of HTML or Markdown while editing. Double-click an element in the preview to quickly jump to its corresponding definition in the source code. With code highlighting and compatibility support for GitHub Flavored Markdown (GFM), UltraEdit is the ideal editor for managing code repositories.
UltraEdit’s search capabilities go far beyond the ordinary. It supports regular expressions, cross-file search, and can easily handle large files up to 4GB. Its precise search capability makes locating what you need effortless.
When horizontal editing is insufficient, column mode allows users to intuitively edit any part of the document along the vertical (Y) axis. This feature is particularly useful for handling tabular data or specially formatted code files.
Whether quickly editing a single file on a server or uploading an entire codebase, UltraEdit’s integrated FTP, SSH, and Telnet features allow users to easily manage remote files and interact with servers within a single application.
The newly refactored menu system offers unprecedented customization freedom. Users can deeply customize the interface layout, choose the familiar “Ribbon” mode, or create a streamlined toolbar containing only frequently used tools, crafting a fully personalized editing environment.
Users can choose from built-in core themes or try a rich collection of community-contributed themes. Additionally, users can freely modify existing themes or create entirely new ones from scratch and share them with other users.
This update introduces several important features that further enhance the editor’s usability.
Automatically detects Git on first run and imports existing settings. In the “File View” under the “Locations” and “Projects” tabs, Git status of repository files is displayed via icon overlays.
Activate via “View » Toolbars/Windows » Toolbars » Git”. Provides shortcut buttons for add, commit, stash, push, pull, etc., and allows quick switching between the Git command line tool and branch manager windows.



Before starting the installation, ensure your Mac system version is not lower than macOS 10.13 (High Sierra). The entire installation process is intuitive and smooth, requiring only a few steps.
Download the UltraEdit for Mac v21.00.0.18 dmg installer from the link provided on this page. After downloading, double-click the dmg file to mount it on your desktop. You will see a window containing the application icon.
This is the most standard installation method on the Mac platform. Drag the “UltraEdit” icon in the window onto the adjacent “Applications” folder icon. The system will automatically begin the copying process.
After copying is complete, go to “Launchpad” or the “Applications” folder, find and double-click the UltraEdit icon. On first launch, the system may display a security prompt stating that the developer cannot be verified. This is macOS’s Gatekeeper mechanism.
At this point, you need to open “System Preferences” > “Security & Privacy” > “General” and click the “Open Anyway” button at the bottom of the page. Then launch UltraEdit again, and it will work normally.
After the first launch, the software will display an activation window. Follow the on-screen instructions, enter the activation code information we provide, and click the “Activate” button. After successful activation, it is recommended to restart the software to fully unlock all features. Then, you can adjust fonts, themes, and shortcuts in “UltraEdit” > “Preferences” according to your personal preference.
We have compiled several questions that users care about most, hoping to help you quickly resolve any doubts during use.
Answer: This is a macOS security mechanism. Please go to “System Preferences” > “Security & Privacy” > “General”, find the blocked software at the bottom of the page, and click “Open Anyway”. If the button is grayed out, first click the lock icon in the lower-left corner to unlock it.
Answer: Please ensure you have completely disconnected from the network and entered the activation code strictly in the format we provided (including hyphens). If it still doesn’t work, check whether you have properly closed any previous version of UltraEdit. If the problem persists, please contact our customer service for the latest activation code.
Answer: After closing UltraEdit, press Cmd + Shift + G in Finder, enter the path ~/Library/Preferences, find the file named “com.idmcomp.ultraedit.plist” and delete it. After restarting UltraEdit, all settings will be restored to default.
Answer: Column mode editing is a signature feature of UltraEdit. You can enable it via the menu bar “Edit” > “Column/Block” > “Column Mode”. A quicker way is to use the shortcut Cmd + Shift + B. Once enabled, you can vertically select text areas with the mouse.
Answer: First, check whether your network connection is normal. Second, confirm that the FTP server address, port, username, and password are correct. UltraEdit uses active mode by default. If the server requires passive mode, modify the connection settings in “File” > “FTP Account Manager”.
Answer: UltraEdit has built-in support for over 20 mainstream programming languages, including C/C++, Java, Python, PHP, JavaScript, HTML, CSS, SQL, etc. If your language is not in the list, you can manually add or import language files via “Advanced” > “Configuration” > “Editor” > “Syntax Highlighting”.
Answer: UltraEdit integrates powerful file comparison functionality. After opening two files, click “File” > “Compare Files” in the menu bar, or use the shortcut Cmd + Shift + C. UltraEdit will display the two files side by side and highlight differences in different colors, making it easy to merge or modify.
Answer: This is usually caused by having too many large files open or not restarting for a long time. It is recommended to regularly clear the recent files list in the “File” menu. Additionally, in “Preferences” > “Advanced”, you can adjust the memory cache size to optimize performance.
Mastering these shortcuts can significantly improve your efficiency in UltraEdit. The following table lists some of the most commonly used shortcut combinations.
| Shortcut | Function Description | Category |
|---|---|---|
| Cmd + Z | Undo the last operation | Edit |
| Cmd + Shift + Z | Redo the undone operation | Edit |
| Cmd + D | Duplicate the current line and paste below | Edit |
| Cmd + Shift + B | Toggle column mode (block selection) | Selection |
