Download updates only

By default, LockRattler both downloads and installs updates. There are occasions when you may prefer only to download updates for the time being, and decide whether to install them later. For example, a bug in MRT version 1.68 caused problems on many Macs. If you wish to be cautious, you could just download future updates to MRT then, after a couple of days, if the latest update appears to be problem-free, you could install it.

To disable automatic installation, select the Install Updates command in the LockRattler menu. It will then become unticked and show the words Download Updates . Select that again to turn automatic installation back on.

To remind you that updates are only being downloaded, when installation is disabled a ⚠️ warning triangle is displayed in LockRattler’s window, and buttons which normally read Install … are changed to read Download … instead.

Downloaded updates are saved in the /Library/Updates folder, which is automatically opened for you when downloading is complete. Apple’s documentation (from 2012) warns that those Installer packages “are not designed to be installed by double-clicking the packages in that directory: always use [softwareupdate] --install or the App Store to actually perform the install.” However, in Mojave and later that doesn’t appear necessary. Downloading can also result in spurious errors being reported when an update is in fact perfectly good.

Downloading is performed using the same commands for download and install, but with -d used instead of -i .
