TIL that Icon Composer uses Garbage Collection and thus can't run on Sierra. Dammit, I was still using that, mostly for quick scaling.

Version 1.4.1 does run on Sierra (whereas 1.4: PPC only, and 2.0: GC). But it only goes up to 128x128 icons, and scaling doesn't work.

If anybody wonders why I'm still hesitant about ARC, this is why. (See also: pref panes, where GC was first mandatory, and then illegal.)

@petermaurer And Automator actions. Broke compatibility there since the same file can’t be both at once. :(

@mjtsai @petermaurer Apple essentially went back to manual retain/release runtime* and got “GC” via smarter compiler. *mostly

@mjtsai @petermaurer FTR it took quite a while before I jumped on the ARC-train as well.

Loading seems to be taking a while.
