Description
Apple has introduced ARC (Automatic Reference Counting) a long time ago. However, MacVim still mostly uses manual reference counting, which actually introduces bugs like #1164. ARC will not solve everything but should help reduce this class of bugs, and even the lowest required macOS (10.9 at the moment) has long supported it.

Research direction
Start by surveying MacVim’s native macOS code to identify where manual reference counting is used, then read issue #1164 for the motivating bug. Done means migrating the applicable code to ARC while preserving existing behavior and checking for regressions across the application.
