Where Does macOS Store Panic and Crash Logs?
macOS files kernel panics and crash reports in DiagnosticReports, one file per incident with hardware details.
Last updated
Every Mac crash writes its autobiography. Kernel panics land as .panic files with backtraces and loaded extensions. App crashes land as .ips files with thread states. Both collect in DiagnosticReports.
The directory is the first stop for recurring instability. Timestamps group incidents, and identical signatures across weeks convict drivers or hardware. Console surfaces the same files prettily, but the folder allows copying and grepping.
Where macOS stores this, by platform
/Library/Logs/DiagnosticReports
Kernel panics are .panic files, app crashes .ips files. Copy recent ones for support tickets; clear old months to reclaim space.
Frequently asked questions
How do I read a panic report?
Open the newest .panic file and read the top lines naming the faulting extension or process. Recurring identical panics point at hardware or a driver; scattered ones suggest RAM or heat. Attach the file to support tickets.
Can I delete old crash reports?
Yes, .ips files accumulate per crash and nothing auto prunes aggressively. Keep recent ones for pattern matching and clear older months when disk space matters. Active investigations keep everything.
