Sublime Text 4.0 on Mac

Anyone who writes code, markup, or plain text on a Mac will find a place for Sublime Text 4. Build 4215 runs natively on both Intel and Apple Silicon machines, so it slots in neatly alongside your other tools without extra translation layers.

Editing code

Column selection and multiple cursors let you change several lines at once. Syntax checking runs as you type, and the command palette handles indentation, reformatting, and line joining without reaching for the mouse.

Markup and prose

Auto-save keeps your work safe, and the split-pane view shows up to four files side by side — handy when you’re tweaking CSS alongside HTML or referencing documentation while you write. Visual themes are easy to swap, and more are available from the package ecosystem.

Keeping your setup current

Installed packages update themselves from their repositories, so your editor stays in sync with the projects you work on. Sublime Text works on macOS, Windows, and Linux, making it a consistent companion across machines.

Customise defaults before opening a project

Before you open a project, it pays to customise a few defaults. Open Preferences > Settings from the menu and you’ll see two panes: the defaults on the left and your user overrides on the right. Start with these:

• font_size – the default is 10, which is small on modern displays. Try 12 or 14.
• translate_tabs_to_spaces – set to true if your team uses spaces. Sublime Text will convert every tab as you type.
• tab_size – most projects expect 2 or 4. Set it once and forget it.
• word_wrap – tick true for Markdown or prose; leave false for code.
• auto_save – I turn this on for anything I edit more than once. The on_focus_lost option saves when you switch windows.

These tweaks take effect immediately. No restart required.

Workflow: building and testing a Python script

Here’s a typical task from start to finish. You want to write a short Python script, run it, and fix any errors without leaving the editor.

1. Open a file. Create a new file (Cmd+N) and save it as hello.py. The syntax highlighting kicks in as soon as Sublime Text sees the .py extension.
2. Write your code. Autocomplete suggests keywords and variable names as you type. For a quick test, type print("hello"). The minimap on the right shows the file structure at a glance.
3. Switch to a build system. Open the Tools menu, pick Build System, and choose Python. Sublime Text already knows how to run a Python script through your system’s Python interpreter.
4. Run the script. Hit Cmd+B. The output appears in a panel at the bottom of the window. If there’s a syntax error, Sublime Text highlights the line so you can fix it straight away.
5. Edit and rerun. Change the code and press Cmd+B again. The build panel updates in place.

You never opened a terminal. The whole cycle stays inside the editor.

Universal binary for Intel and Apple Silicon Macs

Sublime Text 4 Build 4215 is a Universal 2 binary, so it runs on Intel and Apple Silicon Macs alike. The minimum macOS version is 10.13, and the latest build fixed a compatibility issue with 10.13 and 10.14, so older machines are still supported. The app itself is lightweight by design — no background services, no forced updates. Installed packages update themselves quietly when you launch the editor, and the package manager lets you add or remove them without restarting. You’ll find the editor responsive even with several panes open and a minimap visible. Everything stays in one window.
