At first I thought it was my mistake. Then it looked like a simple error in the interface. But this bug in Mojave’s signposts is more complex. Here’s a workaround.
A new version of Blowhole, the second alpha of RouteMap, and a complete tutorial toolkit to help you get started using log Signposts from Sierra to Mojave.
What do you want from a log browser? Which do you use for the unified log (Sierra and later), or have you given the log up as no longer useful?
Do you want to measure performance or get other info from your app or script? Using Signposts is ideal, and here’s the first glimpse of a new tool to harvest them.
