Sleep prevented by mds

Hi there, I noticed that my system cannot sleep properly, so I run pmset.

Here are the results. The strange thing is that I got "sleep   0 (sleep prevented by mds)". What does it mean? Do you think that all other parameters are good to go?

Recently I managed to fix reboot on shutdown. Maybe its linked with that.

 

iMac:~ diego$ pmset -g

System-wide power settings:

Currently in use:

standby              1

Sleep On Power Button 1

womp                 0

autorestart          0

hibernatefile        /var/vm/sleepimage

powernap             0

networkoversleep     0

disksleep            10

sleep                0 (sleep prevented by mds)

autopoweroffdelay    28800

hibernatemode        0

autopoweroff         1

ttyskeepawake        1

displaysleep         0

tcpkeepalive         1

standbydelay         10800

 

Thanks!

I have the same behaviour. 

The computer doesn't sleep. Even when I click on sleep it doesn't do anything.

If I click three times on sleep, it seems that it works, but after a moment, the PC reboots.

 

I don't know if this has something to do with Aptio firmware (Is a Lenovo desk PC, Aptio V firmware).

I've seen updates for the BIOS, but I'm afraid of breaking things :unsure:

I've tested your configuration. I have no sensors in HWSensors (Obvious, you deleted the kexts from Clover). I have no sound (I need VoodooHDA).

But this time when I click on sleep, the Login page kicks off. If I do that three times (don't know what's happening here haha), the PC sleeps (it doesn't reboot). The computer can wake normally. 

I don't know what happens if the sleep time is longer. I have to test it.

Thanks!

I tried to boot without voodootscsync, but I cannot reach the desktop. It stays on the Apple logo. The system is working under it and if I do Ctrl + UP I can't get rid for a moment of the logo. It's strange, reintroducing the kext fixes the problem. I don't know how it's linked.

Update to Catalina worked nice.

 

Only two minor problems:

• iMac is a new device for Apple (copying Serialnumber and Boardserielnumber from old to new plsit doesnt seem to do the trick - is there a solution to this?)

• Standby after x minutes isn't working (mdsync blocks it) - manual standby works fine

 

All I changed in your config was the Serialnumbers and I added the parameter for 9700k.

 

Aside from that everything seems to work pretty nice.
