• OS: OS X 10.13.1
• Terminal: GUI

Repro Steps:

1. Ensure MacVim prefs are: Open Files from applications: (•) in a new window, (v) with a tab for each file
2. Open n > 10 files via R-click "open" (or via File > Open)

Expected behavior:

• Ideally: All n files open as tabs in a given OS WindowManager (NS) window owned by MacVim (and are easily accessible, perhaps via a scrollable/compressible list of tabs or Expose- see OS X's Terminal.app)
• Easier but not as-ideal: First 10 files open as tabs in a given OS WindowManager (NS) window owned by MacVim and remaining files are accessible by clicking the >> that normally appear at the top right of the tab list when incrementally exceeding the 10 tab limit via File > Tab Open...

Actual behavior:

• MacVim seems to process the files but only (the first?) 10 files (tabs) open and one needs to access the other n-10 files via the Buffers menu (which oddly lists all initially selected files, including those that weren't opened)

All files should already show up in the ">>" list. You are using a really old version of MacVim though. Can you update to latest first?

Otherwise there is an open PR that will make tabs better (#1120), but you wouldn't get that anyway if you don't update.

Closing issue for now unless this is reproduced on a recent build of MacVim.
