Capture in parallel
Give each predicate its own named stream. Start and stop streams independently while saved records remain available.

Log Viewer
Keep the signal. Keep the context.
When a problem crosses processes, one stream is rarely enough. Log Viewer brings multiple Unified Logging streams into a focused native workspace, with saved history you can return to.

01 / Why it exists
An investigation that stays readable.
Follow a subsystem, compare related streams, and narrow a long capture without losing the original record. Search and filtering are separate, so finding one message does not have to hide the context that explains it.
Find the relevant moment
Combine text conditions, exclusions, and time ranges. Find navigates saved history and preserves the surrounding records.
Inspect and share
Read complete messages in the inspector and export text or NDJSON with a manifest for further analysis.
02 / A closer look
A considered workspace.

03 / In practice
Make it part
of your day.
- 01
Choose a stream
Set a process or subsystem predicate for the issue you are investigating.
- 02
Narrow the history
Use shared filters and time ranges, then Find to move between matches.
- 03
Keep the evidence
Inspect full record fields and export the relevant history.
Saved captures
Captured records and stream definitions are kept locally. Logs can contain process names, paths, identifiers, and message text.
System privacy
The app shows the fields that macOS makes available. It cannot reveal private fields that the operating system has redacted.
Sharing
Exports contain captured data. Review and redact sensitive records before sending them to another person.
