macOS 13.4

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

There are several bug fixes in the update, with Apple addressing problems with Auto Unlock with Apple Watch, Bluetooth keyboards, Screen Time, and VoiceOver. The update also adds a Sports feed in the sidebar of the Apple News app, and it introduces the simplified beta installation method that was first introduced in iOS 16.4.

Nathaniel Strauss:

Starting in macOS 13.4, there is no longer a way for Mac admins to programmatically manage beta program enrollments. During the 13.4 beta cycle it was announced seedutil is deprecated, to be removed entirely in a future release, and the only path forward to enroll in beta programs being Apple IDs. Apple has taken away a long used utility relied upon by Mac admins and not given much back in return.

Jeff Johnson:

So, uh, Apple credited me (and others) with a security bug, but… they didn’t actually fix the bug.

The description of the bug seems wrongish too.

Significant version changes seen among bundled apps include[…]

Howard Oakley:

There are several factors that could be responsible for Ventura’s updates being so relatively small.


Apple has also been steadily improving the engineering of macOS updates since the heady days of Big Sur. The minimum size of a Big Sur update was 2.3 GB for Intel and 3.3 GB for Apple silicon, which has reduced in Ventura to 0.5 GB and 1.9 GB respectively. On some older Intel Macs, these new more compact updates do take longer to prepare, but are normally far more rapid on Apple silicon Macs.

Big Sur seems to have marked the high tide for macOS update size. With improved engineering, falling overhead from firmware updates, and RSRs, macOS updates should be even lighter in their burden.

Howard Oakley:

The best solution is to enable network diagnostic logging, but as of macOS Ventura 13.4 that has changed and become more inaccessible, as it requires that SIP is disabled.


Update (2023-05-30): Jeff Geerling:

Something’s seriously broken with monitor support in macOS Ventura 13.4

Now both computers I updated go into this endless monitor sleep/wake loop if I have the display off without sleep. […]

Happening on two different model LG 4K displays, one on MacBook Air M2, one on Mac Studio M1 Max.

If I put the Mac to sleep, the monitor powers off and stays off.

In both cases, this has never been an issue until updating to 13.4.

Update (2023-06-01): Dave Wood:

Holy. I updated to macOS 13.4 today, figuring it couldn’t get any worse than 13.2 that I was on. Boy was I wrong.

I use hot corners to put my displays to sleep. I just triggered the corner, and the machine rebooted.

This just happened to me this morning when I accidentally moved the mouse into the corner.

Update (2023-06-13): Dave Wood:

The machine has still spontaneously rebooted about 10 times since updating (a day ago), but, the displays have come back in the same, correct arrangement each time. Could that finally be fixed?


They’ve obviously done something on displays, because sometimes the screensaver only shows up on 2 of the 3 (no idea how that becomes a new bug, but whatever, I’ll take it).

Apple generated this bug in Ventura:

macOS 13 Ventura BREAKS Panasonic TV connection via HDMI

The big problem is that some Macs cannot be upgraded beyond Ventura.

How do you know some Macs can’t upgrade beyond Ventura (currently newest)? Any WWDC scoops for us?
