All right Peter — let’s make this boringly reliable, the way infrastructure should be.

There are three sane ways to keep per-app light mode enforced on modern macOS. They differ mainly in how “enterprise” you want to get.

I’ll walk from simplest → most robust, with opinions included at no extra charge.

Option 1 — Login script (best balance of power vs simplicity)

git bisect is Git’s built-in “binary search” wizard for hunting down which exact commit introduced a bug.

Instead of you guessing and checking commits one-by-one like a caveman with a keyboard, git bisect repeatedly checks out a commit halfway between a known-good state and a known-bad state. You test that commit, tell Git “good” or “bad,” and it halves the search space again. In about log₂(N) steps, you land on the first bad commit.

When you use it • A bug exists now (bad) • You know a point in history where it didn’t exist (good) • You want the first commit that made it break

Typical workflow (manual testing)

petergi

# Try to show the contents of docs/ from the master branch.
# - git show works for files, but may fail for directories.
# - Suppress errors and limit output to 20 lines.
# - If that fails, fall back to listing files under docs/ instead.
# - Always show only the first 20 results to keep output predictable.
git show master:docs/ 2>/dev/null | head -20 \
  || git ls-tree -r master --name-only | grep '^docs/' | head -20
