Just a little over a week after iOS 12.3 hit iPhones and iPads everywhere, Apple has released iOS 12.3.1—a minor update that fixes a couple bugs. Earlier this week, Apple also released a supplemental update for macOS 10.14.5 to fix issues with the T2 chip on some MacBook Pros, addressing a common user complaint.
The iOS update primarily focused on fixing some issues with the Messages app. More specifically, it addresses a bug that prevented the “report junk” option from appearing on applicable threads and another one that made unknown senders appear in your main inbox when they shouldn't. Additionally, it addresses an issue that affected VoLTE calls.
Apple's patch notes for iOS 12.3.1 are as follows:
iOS 12.3.1 includes bug fixes for your iPhone and iPad. This update:
- Fixes an issue that could prevent making or receiving VoLTE calls
- Fixes issues in Messages that could cause messages from unknown senders to appear in your conversation list even though Filter Unknown Senders is enabled
- Fixes an issue that could prevent the Report Junk link from appearing in Messages threads from unknown senders
As usual, the small release also includes some supplemental security updates, which are detailed on Apple's support website.
On the macOS side, Apple's support documentation is unhelpfully vague. It suggests the update focused on fixing an issue related to the T2 chip in newer MacBook Pro computers. A minority of members of various communities of MacBook Pro users have blamed the T2 chip for a few issues, most notably sound problems with certain pro audio devices. Music producers are among Apple's core audience for the laptops.
It's unclear which T2-related problems Apple has fixed here, but the update is available now, and it also has an accompanying list of security changes.
Apple is expected to reveal details about much bigger changes coming in iOS 13 and macOS 10.15 at its WWDC “special event” in San Jose on June 3.
