Hi all

I am having trouble getting my 27 inch late 2013 iMac (running 10.15.5, but was 
happening 10.15.4) to go to sleep.

I have tried the usual things like ejecting external drives, unplugging them 
and plugging them back in.

Zapping the PRAM.

I had this problem a year or two ago and the ejecting and reconnecting the 
drives did the trick but not this time.

Apple says something else to try is to “update the firmware” on the external 
drive.  I am not sure I have ever had any luck finding firmware for drives.  

I have looked at the processes preventing sleep and there are a number of them. 
 This list goes up and down but never seems to get to zero.

 useractivityd
 sharingd
 apfsd  
 hidd   
 cupsd  
 backupd-helper 
 backupd        4
 mds_stores

Does anyone have any thoughts?

Thanks

Adam
