I updated one of my test boxes to 10.13.5 and it promptly crashed and would no longer allow me to login.
I subsequently booted into safe mode and removed Crowd Strike rebooted and got straight in.
No word yet from Crowd Strike re if they're supporting 10.13.5 yet.
Yes, when I brought this up to our InfoSec team they said we were running an older version of the agent, they're supposed to supply me with the latest version for deployment and had neglected to do so.
Words were had.
Please make sure you're using the latest sensor version - 4.6.6808 as it included a fix for the behavior you're seeing. There upcoming 4.7 version has an additional fix for behavior like you described. If you haven't already, please open a ticket with CrowdStrike. Your logs would be very helpful as we've only seen this a couple times.
Also CrowdStrike Falcon officially supports 10.13.5 and works with 10.13.6 beta 1.
