Why MacBook Air has Segmentation fault:11 during 802.11 wifi frame packet capture?
Do you have any idea in this regard?
Perhaps Macbook user might experience install aircrack-NG on Macbook air. Do a research in forums, seems a lot of Macbook Air users has encountered similar problem. Details shown as below:
My Macbook Air OS: Darwin XXXXX-MacBook-Air.local 18.2.0 Darwin Kernel Version 18.2.0: Thu Dec 20 20:46:53 PST 2018; root:xnu-4903.241.1~1/RELEASE_X86_64 x86_64
Problem encountered:
$ sudo airport en0 sniff 1
Capturing 802.11 frames on en0.
Segmentation fault: 11
Airport directory:

Doubt:
See below tcpdump result on my macbook air. It is running fine without any problem. And therefore believing that vendor (apple) has might have some resstriction on driver. Do you think Apple will be resolved this issue in future?
Reference:
sudo tcpdump -i en0
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
