MacVim r182

[ychin]

Updated to Vim 9.1.1887

This update is still built against macOS 15 Sequoia, and does not contain any specific fixes or improvements for macOS 26 Tahoe. That will come in a future update.

Announcements

Moving macOS 10.13 - 10.15 support to legacy release

Currently, MacVim binary releases are available in two versions: a normal version (macOS 10.13 or above), and a legacy version (macOS 10.9-10.12). Starting next release (r183), the normal version will require macOS 11 or above (due to Xcode 26 requirements), and macOS 10.13-10.15 users will need to use the legacy version instead. This will mostly be a transparent change, and the updater will automatically update to the right version. The legacy version should be almost identical to said users as they are using older versions of macOS that can't make use of newer OS features to begin with.

In the future we may remove support for macOS 10.9-10.12 but for now they are still supported.

Features

Better mouse support

• Scroll wheels should feel much better to use in MacVim. A small scroll is now guaranteed to scroll at least one line, and shift-scrolling (horizontal scroll) works correctly now. You can now also turn off macOS's scroll wheel acceleration to scroll a fixed amount of lines in the "Input" settings pane. Add better scroll wheel support and option to disable acceleration #1566
• Mouse buttons 4 and 5 can now be bound to <X1Mouse> and <X2Mouse> in Vim mappings (:h X1Mouse). Support extra side mouse buttons in MacVim (X1 and X2) #1534

New Vim Features

• Diff mode improvements

  • Vim diff can now highlight per-character or per-word differences within a line. Per-character highlighting is now used by default. See :h 'diffopt' under "inline". v9.1.1243

    

  • Diff anchors allow for more explicit controls over how and where the diff algorithm aligns text across files (:h diff-anchors). v9.1.1557

• Lots of auto-completion improvements. Some highlights below:
  • New option: autocomplete. Get completion suggestions as you type. See :h ins-autocompletion. v9.1.1590
  • Fuzzy matching now uses the fzf algorithm. v9.1.1627
  • Popup menu borders can now be styled (:h 'pumborder' / :h 'completepopup'). v9.1.1835 / v9.1.1856
  • Can now specify a custom completion source when using insert-mode completion (:h 'complete'). v9.1.1301
  • set completeopt+=nearest will sort completion items by proximity to the cursor. v9.1.1308
  • Command-line completion
    • Search commands like / and :g can be tab-completed now. v9.1.1490 v9.1.1526
    • Commands like :filetype and :highlight have better auto-completion. v9.1.1340 / v9.1.1138
• New vertical tab panel (:h tabpanel). v9.1.1391
• new bundled optional plugins (use packadd to enable them):
  • hlyank (:h package-hlyank): Briefly highlight region of last yank command
• new commands:
  • :uniq (:h :uniq): Remove duplicate adjacent lines v9.1.1477

General

• Sparkle (updater for MacVim) is now updated to 2.8.0. Sparkle 2.8.0 #1605

Security Fixes

• Fixed MacVim erroneously setting the get-task-allow entitlement, which could allow another user-installed application to inspect it (CVE-2025-8597) Remove get-task-allow entitlement from signed builds #1585

Fixes

• Fixed issue where macOS services (available in the "Services" menu) could not insert text when not in visual mode. Fix macOS services no longer able to insert texts in non-Visual modes #1571 r181 Ctrl key mappings no longer work like they did on r180 (r180 fresh install on new MBP) #1569
• Fixed issue where guifont did not accept PostScript names with underscores (e.g. "CascadiaMono-Regular_Light"). Allow underscores in guifont PostScript names #1600
• MacVim now uses the standard v:colornames variable for choosing highlight colors. Remove Colors.plist and fix CI #1568
• Vim syntax now understands MacVim-specific function showdefinition(). Add "showdefinition" to Vim syntax highlight #1601
