Demonstrates crashing bug in [NSWorkspace recycleURLs:completionHandler:] when trashing over 500 files at once

	//
	// recycleURLs_crash_test
	//
	// Created by Thomas Tempelmann on 01Feb21.
	//
	// Purpose:
	// Demonstrates that using [NSWorkspace recycleURLs:] on > 600 files often leads to a crash on macOS 10.12 and 10.13.
	// In my testing (on 10.13.6), up to 500 items never crash, while it starts crashing sometimes with 650 items
	// and nearly every time when it's over 800. I also get spurious errors on the first recycle interation when
	// using 600 items. This could be a precursor to the crash, but not sure.

Demonstrates that `[[NSURL fileURLWithPath:path] path]` may return a different string than was passed

	// Created by Thomas Tempelmann on 6 Apr 21, updated 8 Apr 21.
	//
	// This code demonstrates a unicode normalization issue with reading file system paths on APFS
	// volumes in macOS.
	//
	// TL;DR – In short, NSURL.path return paths (probably) always in NFD form even if the on-disk
	// name is in NFC form, and even if you passed the on-disk path to NSURL to create it.
	// Other path accessors, such as the canonical path, as well as BSD/POSIX functions
	// will keep giving you the on-disk name.
	// As a result, the name you get from NSURLNameKey may not be identical to the URL's

tempelmann / Add shadow to window screenshow.applescript

Last active August 29, 2022 16:17

An Acorn (macOS) script to add a drop shadow to screenshots of shadow-less windows

	-- This script uses Acorn (tested with version 6.6.4)
	-- to add a light border around a window screenshot.
	--
	-- Screenshots (without the huge macOS shadows) are made by shift-cmd-4, then space bar,
	-- then option-click on window (see https://apple.stackexchange.com/a/120017/17533)
	--
	-- Before use, you need to create a Preset Filter for this, once:
	-- With an image opened, use from menu: Filter / Stylize / Drop Shadow…
	-- Set its options as you prefer (e.g. X/Y offset 0, Blur Radius 2, Opacity 80%),
	-- then save it by clicking the gear icon, choose "Save Filter Preset…" and
