Rogue Amoeba has released Fission 2.4 with a major update to address changes to how iTunes 12.7 deals with ringtones (see “iTunes 12.7 Giveth, but Mostly It Taketh Apps and Ringtones Away,” 15 September 2017). Because the Save as iPhone Ringtone option in previous versions of Fission can no longer pass custom tones to iTunes 12.7, Rogue Amoeba updated Fission’s ringtone saving capabilities (see this Rogue Amoeba blog post and step-by-step
guide for details). The app also improves compatibility with APFS and makes several fixes to avoid crashes when resampling audio.
Shortly after this release, Rogue Amoeba issued version 2.4.1 to fix a critical bug that could cause attempts to save split clips to fail. ($29 new from Rogue Amoeba with a 20 percent discount for TidBITS members, also available from Mac App Store, free update, 10.6 MB, release notes, 10.10+)
