I do not know how specific this is to certain models (I suspect that many are not affected), nor whether this is confined to OS X 10.11.3. It does not appear possible to have the system sleep but not the drives. So if your Mac is affected by this and you want to prevent the disk(s) from being spun down, the only option is to set system sleep to Never. This is reflected in DriveDx’s Power Cycles Count for the hard drive within my iMac’s Fusion Drive, which is currently 766, and is incremented by 1 every time that I wake it from system sleep. However, when the main system goes to sleep, the internal hard drive within the iMac’s Fusion Drive is spun down at the same time. When operating under those settings, display and main system sleep function correctly. These were produced by MacPilot, and confirmed by inspection. To assess this further, I have produced custom power management settings which require a display sleep time of 30 min, main system sleep of 120 min, and hard disk sleep of 0, which equates to never. It is possible that this is because this particular model cannot separate them, because of design limitations or a bug in its power management. Most importantly, it does not separate display from main system sleep. On this iMac Retina 5K 27″ Late 2015 (running OS X 10.11.3), the Energy Saver pane differs from other models in inexplicable ways. However, as I have recorded elsewhere, El Capitan has more general problems in Energy Saver, which differs substantially between models. When this was set using the Energy Saver pane, I was surprised that whenever I woke it up, I could hear the internal hard drive spin up. I leave my iMac running all the time, and have set it to sleep the display and system, but not to sleep the hard drives. Total cost for the parts was around 50 dollars.I had suspected that there was a bug in power management on some (at least) models of Mac for some time. For Audio output, a volume-adjustable 3W PAM8403 amp and two Apple iMac G4 internal speakers are utilized for 44KHz stereo playback. I used a 4GB card, but any size could be used. Also required is an SDHC MicroSD card to store the Chime MP3 file. The updated method uses an MOL-AU5120 mp3 module from MDFly Electronics. This video of the old chime shows that the ISD1820 lacks the rich sound of the original Apple. The details of that method are found in this post. #Macpilot el capitan softwareKoingo Software says that MacPilot sports more than. MacPilot sports a lot of the same features Ive described in utilities elsewhere in this roundup, but adds a lot more too. Althought the solution worked, the sound quality simply wasn't that great due to the limitations of the module. OS X 10.11 El Capitan: TinkerTool 5, v5.7 macOS 10.12 Sierra: TinkerTool 6, v6.5 macOS 10.13 High Sierra: TinkerTool 6, v6.5 macOS 10.14 Mojave: TinkerTool, v7.4.2. It worked, but was only an 8KHz recording that was done over-the-air to the module from an iPad. Up until recently, I've used the Arduino ISD1820 sound recorder module to emulate the Apple Chime. There are other methods of doing this, I'm sure, but this was an inexpensive and versatile solution which produced excellent results. Its installed in three completed iMac G5 A1076 projects that I've done for myself and other family members over the last 2 months. I've recently worked out a simple solution for the Apple Startup Chime. Building a CustoMac Hackintosh: Buyer's Guide ![]()
