Quite recently, my iMac makes a sound while sleeping (like a "breath"; the one it makes when you actually "awake" it) but nothing shows in the screen.
Seems like other users had the same problem, but after read them:
- Printer queue is empty
- Network access during sleep is disable
- I don't think Time Machine is the source of the issue (although I could be wrong).
I don't remember if I installed some software recently, so I don't have any clue what is causing this… Could anyone, please, give me a hint? (Please find an EtreCheck report below).
Thanks in advance!
