Eliot Miranda uploaded a new version of BytecodeSets to project VM Maker: http://source.squeak.org/VMMaker/BytecodeSets.spur-eem.58.mcz ==================== Summary ==================== Name: BytecodeSets.spur-eem.58 Author: eem Time: 1 September 2016, 11:33:26.908292 am UUID: 1124d09b-cde5-41a4-9c6d-4a610aa72ee2 Ancestors: BytecodeSets.spur-cb.57 Nuke obsolete class (NewsquekV3).

Branch: refs/heads/Cog Home: https://github.com/OpenSmalltalk/opensmalltalk-vm Commit: f2b5cf27f81e50c65537972a89ddee9e0aac39c2 https://github.com/OpenSmalltalk/opensmalltalk-vm/commit/f2b5cf27f81e50c655… Author: Fabio Niephaus <code(a)fniephaus.com> Date: 2016-09-01 (Thu, 01 Sep 2016) Changed paths: M platforms/iOS/vm/OSX/sqMacUnixExternalPrims.m Log Message: ----------- Fix bad path manipulation in macOS VM We should have been using `stringByAppendingPathComponent:`, not `stringByAppendingPathExtension`. This didn't matter until Sierra, where they improved/increased error checking. @bpollack #39
