Changes include frequent timechecks by timed, harder access to info about keychains, a couple of possible AppleScript bugs, and APFS snapshots.
High Sierra makes two significant changes to the unified log system, from Sierra. Here’s an evaluation of them.
How to identify which keychains are opened when your Mac starts up, and any problems when that happens.
A detailed examination of what happens during the first few minutes after starting your Mac up. Vital for anyone trying to diagnose problems in that period.
Styles let you see the log fields you want, with colour; filters are instant search tools; those and custom processes now have a Preferences sheet.
A post-mortem analysis on attempts to make my iMac dual-boot between Sierra and High Sierra. Can it be done in safety?
Changes made to preferences are now reflected immediately in all windows. Also ported to Swift 4.0 and built in Xcode 9.1.
Added to the bar chart are timestamps of the first and last log entries included, and there are other improvements too.
The odd behaviour of some apps, which quit on their own, but hang around as zombies, and the long battle trying to make sense of logs.
