ReportCrash process eating up to 90% CPU on startup

Hello,

for some days now something strange happens at every startup: a process called ReportCrash eats up loads of CPU and I cannot end it in Activity Monitor (every time I do, it pops up again).

  1. I read in other threads that the process is meant for the system to recover data whenever an app crashes. People suggested looking into the System log to see which app was crashing, and I found out that it was OneDrive, due to it not being compatible anymore with my old OS version (yeah, I know..).
  2. I removed OneDrive from the startup apps and then uninstalled it completely (it wasn't working anyway).
  3. The ReportCrash process keeps popping up on startups and eating loads of CPU, but now System log messages don't give me any clue of what the problem is. The messages that I get are the following:
    • (com.apple.ReportCrash): The DrainMessagesOnCrash key is not yet implemented. If you rely on this key, please file a bug.
    • (com.apple.ReportCrash.Self): The DrainMessagesOnCrash key is not yet implemented. If you rely on this key, please file a bug.
    • (com.apple.ReportCrash.Root[392]): Endpoint has been activated through legacy launch(3) APIs. Please switch to XPC or bootstrap_check_in(): com.apple.ReportCrash.DirectoryService - this then repeats over and over with different growing numbers after (com.apple.ReportCrash.Root[...]).


Anyone might have a clue on what's going on? Thanks for the help in advance.

Crashes can be difficult to identify the reason. Often RAM related, or incompatible application related, it is good to look at the current background applications to see what may be ailing the machine.

Etrecheck is a handy tool for people to do so.

If you give us your report, we can tell you if software that is installed is unnecessary, or if potentially hardware issue exists.

One thing you can do is run the Apple Hardware Test/Diagnostic utility.
