macOS 13.2.1

Juli Clover (release notes, security, full installer, IPSW):

Apple today released macOS Ventura 13.2.1, the a minor to the macOS Ventura operating system initially released in October.

Juli Clover:

According to Apple’s security notes for the updates, The software fixes a WebKit issue that could allow maliciously crafted web content to result in arbitrary code execution. Apple says that it is “aware of a report that this issue may have been actively exploited.”

Update (2023-02-21): Howard Oakley:

A small minority of users experienced something strange when they updated to macOS 13.2.1, or even 13.2. Instead of the updated macOS automatically returning them to the Finder and Desktop once the update was complete, it bounced the Mac into Recovery (or similar, if your Mac is managed) and asked for the password. This article explains what happened, and other accidents that can happen when updates don’t work right.

iOS 16.3.1 and iPadOS 16.3.1

Juli Clover (security):

According to Apple’s release notes, the iOS 16.3.1 update includes multiple bug fixes, addressing issues with iCloud and Siri requests for Find My, plus it adds more Crash Detection optimizations.

The iCloud settings fix may address an issue that could cause some people not to be able to toggle on automatic iCloud backups on the iPhone and the iPad, a problem that some users have been experiencing since the launch of iOS 16.3.

Crash Detection optimizations likely address ongoing issues with Crash Detection reported at ski resorts and amusement parks.

Yesterday, I somehow triggered Apple Watch’s fall detection for the first time. I was at a ski resort, but I didn’t fall, and it detected the “fall” while I was walking in a flat parking lot at a constant pace.

Formulas for Optical Adjustments

Marc Edwards:

Using the area works well for a circle, but, what about a donut? The hole in the middle reduces the total area. This also happens with stars and other shapes. Holes and concave segments should probably be ignored. A method to do this exists, and it’s typically called a convex hull. It’s like stretching a rubber band around the entire object. That’s probably a pretty good formula to work out visual weight that matches human perception. Here’s some more shapes, using the convex hull area to set the scale.

[…]

For triangles, the center of the bounding box often does not feel like the center of the triangle, and aligning by this method looks incorrect.

Triangles have many different types of centers, including centroid, incenter, circumcenter, and orthocenter. For equilateral triangles, those all coincide, so it doesn’t matter which is used. Aligning the triangle centroid to the center of the circle now looks right — the distance from the triangle points to the edge of the circle are consistent and it appears perfectly centered.

Something Only Apple Can Do

Dave Verwer:

I don’t think I’ve ever seen anything that sums up the balance of the pros and cons of life in the iOS App Store better than this Apple Developer News post from last week. It announces more flexibility to the billing grace period feature for subscriptions and subscription trials in your apps.

[…]

All that logic, all the edge cases, and all the implementation time. All done by Apple.

[…]

What if you wanted to change how your subscription billing works or add features like these for your app five years ago? What if you believe that the lack of this feature (or a hundred others) costs your business money, and if you were in control of your checkout and subscription logic, you would have changed it?

Android App Cloning

Ron Amadeo (via Peter Steinberger):

The feature leverages Android's multi-user system to have two copies of the same app but with different data, allowing you to log in to each with different accounts. Some apps support multiple accounts and some don't, but this feature would bring multiple account support to everything. It would also bring a great deal of consistency to having multiple accounts—every app could deal with multiple accounts in the same way, with one icon for account number one and a second icon for account number two.

This sounds great. iOS doesn’t even have real multi-user support.
