When does an M1 Mac validate its Sealed System Volume? Who designed its display interface? How soon does Find My Mac launch? So many answers found in the log.
Time has changed in M1 Macs, with the Mach clock ticking every 41.67 nanoseconds. This affects all log entries too, and works differently in Rosetta.
Adds a new log view of background task scheduling and dispatch, greatly improves volume info, and fixes a rare crash.
The more you look at changes to Mach Absolute Time coming in Apple Silicon Macs, the more messy they become, largely because the docs are so incomplete.
How long does it take to write a Signpost to the unified log? Measuring this is essential if you’re going to use them to measure performance.
Makes it easy to write, harvest and analyse Signposts in the log to measure performance. Important fix for Apple Silicon too.
Since we switched to Intel Macs, Mach precision time has ticked away in nanoseconds. That’s won’t be true in Apple Silicon Macs, and could have strange results.
How you can write entries in the unified log which are informative, easily retrieved, and extremely simple.
Your Mac starts up after kernel panic, and shows mystifying details about that panic. Here’s how to get the most out of that information.
What’s the difference between a crash and a panic? How can you tell what’s likely to have caused a panic?
