How to read macOS crash reports
Understaing these reports can be difficult as they are usually big. Here is how you can decipther a crash report:
1. The first section of a crash report includes what process crashed. Something like this:
In this case, said process is WebKit (Safari).
2. The next section of a crash report includes date/time and operating system, like this:
3. The next section includes more crash details (The Exception), something like this:
There are four common exeption types, according to Apple:
EXC_BAD_ACCESS/KERN_INVALID_ADDRESS — This is caused by the thread accessing unmapped memory. It may be triggered by either a data access or an instruction fetch; the Thread State section describes how to tell the difference.
EXC_BAD_ACCESS/KERN_PROTECTION_FAILURE — This is caused by the thread trying to write to read-only memory. This is always caused by a data access.
EXC_BAD_INSTRUCTION — This is caused by the thread executing an illegal instruction.
EXC_ARITHMETIC/EXC_I386_DIV — This is caused by the thread doing an integer divide by zero on an Intel-based computer.
The next section includes backtrace information. There can be one or multiple threads. In reverse chronological order, each thread shows the series of events .
To understand this section, find the thread that crashed. You can easily find that, because the report will say something like this: Thread (thread number) Crashed. This section explains what lead to the crash.
Like this:
There are four columns here:
- The first one is the frame number (reverse chronological), like 0, 1, 2, 3….
- The second one is the name of the program or other process that performed the task. In this instance, com.apple.WebKit.
- The third column is the counter program address.
- The fourth column is the task.
From this example, we know that, for example, “com.apple.WebCore 0x00007fff3e26977a WebCore::HTMLMediaElement::mediaCanStart(WebCore::Document&) + 90” is responsible for the crash.
Now you know what caused the crash and series of events triggered the crash. This will help you idendify the problem and then address it appropriately.
If your problem is a third-party app, you may want to contact its developer. Tell them your problem and you may want to send a copy of this crash log. You can click the share icon in the Console app to send the report.
