High Sierra makes two significant changes to the unified log system, from Sierra. Here’s an evaluation of them.
Sierra
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.
Four versions of the same app to demonstrate different app states in Sierra and High Sierra, and how your apps can join the undead.
Added to the bar chart are timestamps of the first and last log entries included, and there are other improvements too.
Rising to the challenge of the unified log: how to work around lack of information, and a surfeit of information. More function and power.
Are you getting over-notified? Who’s in charge – you the user, or macOS? Getting control of notifications, both local and remote.
