When it comes to OS updates, we at Macworld encourage users to install them as soon as possible. Updates sometimes bring nice new features, but the most important ones are bug fixes and security updates.

But many believe that there is a good argument for waiting, and with iOS 16.4, iPadOS 16.4, and macOS 13.3, Apple has proven that argument. These updates introduced a number of bugs that caused issues, none of which are minor. All of them contain bugs that can seriously impair your ability to use your devices.

Apple appears to be aware of the issues, and MacRumors reports that iOS 16.4.1 is in the works to fix iPhone bugs. The macOS Ventura 13.3.1 update has not been tested, but we assume it is also in development. In the meantime, these are some of the widespread bugs found in iOS 16.4 and macOS Ventura 13.3 that will hopefully be fixed in a point release, and if you haven’t updated yet, you should probably wait.

Known issues in iOS 16.4 and iPadOS 16.4

• weather app: The Weather app, which many of us rely on to set the tone for the day, has problems displaying the forecast. Earlier this week, the Weather app suffered a complete data transfer failure, and although service has been restored (according to the Apple System Status website), the app is still unstable.
• Battery discharge: There always seems to be a high-profile number of users who experience a reduction in battery life when an update is released. But the number of anecdotal accounts, such as those in the Apple support community, seems to be more common with iOS 16.4. YouTuber iAppleBytes has a video demo of a Geekbench battery test with iOS 16.4 that backs up the battery life claim.
• home application: The Home app used to control smart home devices received an update to its architecture, but Apple stumbled during its rollout. It was originally offered in iOS 16.2 but was withdrawn and later released in iOS 16.4. Now there are a number of complaints about the redesigned application, according to iMore.

macOS Ventura 13.3 known issues

• Universal management and handover: These iCloud connectivity dependent features stopped working for some users after installing 13.3. The workaround involves logging out of iCloud and then logging back in, but that can cause a whole bunch of headaches, especially if you’re using iCloud to sync your photo library.
• home directoryA: macOS 13.3 introduces an issue with user home directories stored on external drives. The workaround for this issue involves disabling System Integrity Protection, but this is not ideal. An email from Macworld reader Andy in the UK suggests that there are more issues with iCloud and SIP than meets the eye, and I tend to agree.
• a cursory glance: Although I didn’t have this issue, many users in the Apple support community are unable to get Quick Look to work on macOS 13.3. As someone who uses Quick Look all the time, this mistake will drive me crazy.
