Catalina - odd wake behavior

GregP9999 · Nov 6, 2019

Posting this in case someone has run into similar behavior. Since upgrading to Catalina, I've run into an odd wake behavior. Feels like a Catalina bug since I never had this issue with Mojave, but I haven't run across any other reports of it.

When put to sleep following a restart, there's an initial wake timer set @ ~24hrs - might coincide with a 24hr DCHP lease renewal but that's unclear:

019-11-04 18:03:33 -0500 Wake Requests [*process=dasd request=Maintenance deltaSecs=86113 wakeAt=2019-11-05 17:58:46] [process=powerd request=UserWake deltaSecs=1781787 wakeAt=2019-11-25 09:00:00 info="com.apple.alarm.user-visible,416"]

When that timer expires, the system will wake up (even though Power Nap is disabled), run for a minute or two, then go back to sleep. It then sets a new timer:
2019-11-05 17:53:41 -0500 Wake Requests [*process=dasd request=Maintenance deltaSecs=19357 wakeAt=2019-11-05 23:16:18] [process=powerd request=UserWake deltaSecs=1695979 wakeAt=2019-11-25 09:00:00 info="com.apple.alarm.user-visible,416"]

It then gets weird, when it wakes @ 23:16, the timer durations become significantly shorter until eventually it's waking up every 3-5 minutes:
2019-11-05 23:20:27 -0500 Wake Requests [*process=dasd request=Maintenance deltaSecs=596 wakeAt=2019-11-05 23:30:23] [process=powerd request=UserWake deltaSecs=1676372 wakeAt=2019-11-25 09:00:00 info="com.apple.alarm.user-visible,416"]

2019-11-06 02:01:05 -0500 Wake Requests [*process=dasd request=Maintenance deltaSecs=230 wakeAt=2019-11-06 02:04:55] [process=powerd request=UserWake deltaSecs=1666735 wakeAt=2019-11-25 09:00:00 info="com.apple.alarm.user-visible,416"]

Based on kernel logs, this is what's triggering it - this log event always lines up with the wake time.

Anyone seen a similar signature?
Power Nap is off. I've had darkwake=0 set as a boot param since I set this system up, but I deleted the param to see if it made a difference - no change.

+1
restart hackintosh can delay night awake 24hrs，so I scheduled
restart at 00:00:00 everyday.

Not a bad solution. For now I've just shutting down every night.

any solution to this rather than shutting down or rebooting?

I have same problem on real iMac. I will try to kill dasd every 30 min via cron.
sudo env EDITOR=nano crontab -e
then
*/30 * * * * kill -15 $(/usr/local/bin/pidof dasd) > /dev/null

I've been either shutting down at night or ensuring that I get a restart in before the initial 24 hour maintenance activity trigger. I did a little bit of investigating trying to determine what the maintenance activity is or why it eventually gets into a very short restart cycle, but didn't have much success.

I thought I was the only one! I started seeing this on 10.15.1, although in my case it happens after about 40 hours (regardless of what has happened), and always ends in a hard freeze (not even a Kernel Panic). I suspect it's an Apple bug as it's so similar to real Mac issues. Interestingly, because I assume it's power management related, I looked through some pmset commands, and found that 'pmset -g powerstate' causes an almost instant panic. Before it crashes the list is completely full of USB devices (many more than I have). It looks like there's an infinite loop during enumeration causing a buffer overflow. I can't change much about my USB config, but if you have the same issue you might want to look there.

In the meantime, a daily restart is all that works for me (even killing dasd has no effect). It's hard to debug something like this when you only get one shot every two days (and it's always in the night).

My MacBookPro14,2 (2018, touchbar) has the exact same issue and I'm religiously trying to keep this laptop as close to default/stock as possible. It also has barely any software installed (VMware Fusion probably being the most "intrusive" package).

Does the darkwake=0 boot-arg actually do anything? Is there a way to verify? Because pmset logs containing DarkWake lines makes no sense if darkwake=0 actually disables DarkWake.

I can't believe how much effort is required to just make that damn laptop sleep..

Edit: Catalina.

I'm not convinced darkwake bootflags have any effect either. The closest documentation we have is https://www.tonymacx86.com/threads/darkwake-deciphered.236850/ and even then most flags are deprecated. Your pm log looks the same as mine. I think it's the kind of thing Apple wouldn't let you disable anyway. God knows why it can't do it all in one go.

Posting this in case someone has run into similar behavior. Since upgrading to Catalina, I've run into an odd wake behavior. Feels like a Catalina bug since I never had this issue with Mojave, but I haven't run across any other reports of it.

When put to sleep following a restart, there's an initial wake timer set @ ~24hrs - might coincide with a 24hr DCHP lease renewal but that's unclear:

So far, this appears to have been resolved with 10.15.2. dasd maintenance wakes no longer appear in the PM logs.
