Apple on Monday released a minor update for iTunes. iTunes 12.4.3 fixes a bug that could cause playlists edited on iOS devices not to appear properly in iTunes. Once iTunes is updated, the syncing function should once more work properly, and playlist changes should show up across all devices.
iTunes 12.4.3 is available for Mac users through the “Update” tab in the Mac App Store, via the “Check for Updates…” function in iTunes, or via download from the Apple website. Windows users can download the update via the Apple Software Update utility, or via download from the Apple website.
The recent iTunes updates have all been of the bug fixes variety. Two weeks ago, Apple offered up an iTunes 12.4.2 update, which fixed an issue that occurred when listening to a music track in Apple Music that was shorter than 60 seconds long.
