\n

With macOS 15.4, Apple is bringing Mail Categorization to the Mac. The Mail app features dedicated categories like transactions, updates, and promotions, with important emails organized into a primary section.<\/p>\n

Apple News+ subscribers now have access to an Apple News Food section with recipes, food articles, and more. There\u2019s a new Sketch style for Image Playground, Memory Movie support in the Photos app for custom slideshows, and new emoji characters.<\/p>\n<\/blockquote>\n

See also: Mr. Macintosh<\/a> and Howard Oakley<\/a>.<\/p>\n

Apple<\/a>:<\/p>\n

\n

FSKit<\/a> is now available, enabling delivery of user space file systems as Application Extensions. These file systems support integration with DiskArbitration.<\/p>\n

[\u2026]<\/p>\n

To enable the new HTTP loading mode, set usesClassicLoadingMode<\/code> to false on URLSessionConfiguration<\/code>. The new loading mode will become the default in a future release.<\/p>\n

[\u2026]<\/p>\n

Fixed: M4 Macs are unable to launch virtual machine, and attempts result in a system restart.<\/p>\n<\/blockquote>\n

Khaos Tian<\/a>:<\/p>\n

\n

FSKit on macOS 15.4 doesn\u2019t seem to work without manually writing some files to a place where we shouldn\u2019t\u2026 Did anyone at Apple tested this before shipping it \ud83e\udee0<\/p>\n

TIL they put this toggle under \u201cGeneral -> Login Items & Extensions -> File System Extensions\u201d\u2026 macOS settings is a mess \ud83d\ude1b<\/p>\n<\/blockquote>\n

Quinn<\/a>:<\/p>\n

\n

Historically the boundary was at the transport layer. When you enable the new loader, URLSession<\/code> uses Network framework\u2019s HTTP implementation.<\/p>\n<\/blockquote>\n

Jeff Johnson<\/a>:<\/p>\n

\n

Incidentally, before updating my Mac mini, I got an \u201cUpgrade to macOS Sequoia\u201d notification even though the Mac was already running Sequoia (15.3.2).<\/p>\n

[\u2026]<\/p>\n

After the updates, both my Mac mini and my iPad showed one of the most confusing \u201cwelcome\u201d screens that I\u2019ve ever seen. Indeed, they confused even me!<\/p>\n

[\u2026]<\/p>\n

The two options given were \u201cContinue\u201d and \u201cOnly Download Automatically\u201d. Which of those two did I want? Confused, I selected Continue.<\/p>\n

I turns out that I wanted neither<\/em>.<\/p>\n<\/blockquote>\n

It looks like a dark pattern to encourage people to auto-update.<\/p>\n

Rich Trouton<\/a>:<\/p>\n

\n

I have not found a way to suppress this screen using a defaults<\/a> command, but it is possible to suppress the Update Your Mac Automatically<\/strong> screen on macOS Sequoia using a configuration profile.<\/p>\n<\/blockquote>\n

Paul Haddad<\/a>:<\/p>\n

\n

Our long Apple Intelligence nightmare is over, I upgraded to 15.4 on two machines and neither turned that stuff back on! Still wasting several GB of storage, but it\u2019s progress.<\/p>\n<\/blockquote>\n

Marcin Krzyzanowski<\/a>:<\/p>\n

\n

The release of macOS 15.4 builds is different from that of RC2. YET my computer does not update.<\/p>\n<\/blockquote>\n

Rich Trouton<\/a>:<\/p>\n

\n

Apple has added new management options for Apple Intelligence as part of the release of macOS Sequoia 15.4.<\/p>\n<\/blockquote>\n

Marcin Krzyzanowski<\/a>:<\/p>\n

\n

PSA: don\u2019t upgrade macOS to 15.4 if you need to use Xcode 16.2 – the lldb debugger is crashing on start<\/a>.<\/p>\n<\/blockquote>\n
