macOS Sierra 10.12.3 update is now available

Apple has today made available the next update to macOS Sierra, version 10.12.3, from the App Store.

The fixes detailed include two for the new MacBook Pro models, which improves automatic graphics switching, and graphics issues when encoding Adobe Premiere Pro projects. Other issues addressed include searching of scanned PDF documents in Preview, compatibility of PDF documents which are exported with encryption enabled, and importing images from digital cameras into third-party apps.

Security fixes include updating PHP to version 5.6.28, improved memory management in Bluetooth, a memory corruption vulnerability in graphics drivers, a cross-site scripting issue in Help Viewer, two vulnerabilities in the kernel, and fixes for libarchive and Vim.

These are surprisingly few for an update which is just over 1 GB in size, so you should expect that there are many other unannounced improvements.

Here, on my iMac17,1, the update took just 12 minutes to install. The first phase threatened to take 22 minutes, but took less than ten. The computer went through two startup chimes, and after the second there was another timer indicating 14 minutes to complete; that in fact took much less than that. Eventually, the iMac returned to the screen which it had left when the install started, without any logging in or other procedures.

Most of the bundled apps – including App Store, Calendar, Contacts, iBooks, Mail, Maps, Messages, Photos, and Safari – have been updated, as has roughly a fifth of macOS. No doubt we’ll discover what has been fixed and changed as we use it.

Safari has been updated to version 10.0.3, which is also available for Yosemite and El Capitan. This addresses six vulnerabilities in WebKit to various forms of crafted content.

If you need an offline installer, the Combo update to 10.12.3 is available for download here, and the incremental update from 10.12.2 to 10.12.3 is available here.

Oh – and the long-standing Finder column width bug still hasn’t been fixed.
