MacBook lid opened while away (possible bug?) I was recently trying out the command:
log show —style syslog | fgrep ”Wake”

I noticed that there were two EC.Lidopen events at a time when I had left the MacBook in my locked apartment. The two logs had simultaneous time stamps at 15.30:05, which strikes me as bug-like since a normal wake-up would just render one EC.Lidopen event... not two of them in the same second?

Powernap is disabled for battery mode, and the computer wasn't plugged in.
The computer was put in sleep-mode after I last used it, and had WiFi but not Bluetooth enabled. I have double-checked that other events are correct time-wise so that it’s not a time-setting issue. Is there a possibility that it might be due to a bug?

Here is the output:

Thanks for your help,

Using pmset -g log, I have found that EC.Lidopen occurred in conjunction with scheduled wake ups. And true, waking the computer by opening the lid does not render an 'EC.Lidopen' wake-up reason but rather a 'Host (0x01)'.

An EC.Lidopen event in my case is generated when the Mac goes to sleep either after closing the lid manually or after it wakes from Deep Idle due to maintenance and goes to sleep again. I think a lot of people who use the wake up reason to find if someones using their computer can be confused by this function...
