MacBook and iMac both crash & rebooted about owl HOT 3 OPEN

Hi,
thank you for your report. We discovered this issue as well (last week) and I put some focus on it to resolve it. I could track it down to the call to pcap_inject which is used to inject WiFi frames.
Unfortunately, this kernel panic is triggered by a potential bug in Apple's kernel implementation.

This error only occurs on Macs with a T2 chip (so the newer models). The MacBook Pro 15" 2019 I used to test it for example has such a chip and it results in the same crash.

I opened an issue here the-tcpdump-group/libpcap#922 and we discovered that we will now send a bug report to Apple as this cannot be fixed on our side at the moment.

Kind regards
Alex

Thank you for your reply.
After reading your post, I tried using your another program "OpenDrop" instead of this OWL, which apparently is not going to be working on my recent macs any time soon.
Surprisingly, this time, OpenDrop worked fine on both of my iMac (2019) and MacBook Pro 16" (2020)!
How is it possible that OpenDrop works while OWL does not?
I thought OpenDrop was built right upon your OWL.

Hi,

On macOS you have native support for Apple Wireless Direct Link (AWDL) and OpenDrop builds on top of AWDL as AirDrop does. OWL is an alternative implementation of AWDL and therefore only needed on Linux or on macOS, if more granular control over the AWDL network is needed.

OpenDrop for example is not able to make AWDL connections automatically. This has to be handled by the macOS system itself. OWL can do that and therefore can be more reliable for OpenDrop.
