ggrpitt Posted April 15, 2017 Share Posted April 15, 2017 I just upgraded to 10.11.6 from my original 10.11.3 install and sleep/wake stopped working: the computer sleeps OK, but either reboots or fails to turn on the monitor when waking, requiring a reboot. Tried several darkwake flags (which worked under 10.11.3) but none fixed the issue. Tried the various USB flags in clover, but none fixed the issue. Removed all peripherals except for a DP monitor, keyboard and mouse, and the issue persists. Any suggestions? My system is a 9020, i7-4790, 16GB, HD4600 (no separate GPU). Samsung EVO 250 SSD (OS X), WD Velociraptor (Windows), Toshiba 2TB (data storage). Link to comment Share on other sites More sharing options...
ggrpitt Posted April 28, 2017 Author Share Posted April 28, 2017 Somehow the sleep issues were resolved after I installed a cheap PCI-E bluetooth/wifi board. My guess is that now the optiplex looks a lot more like the imac14,2 it is supposed to be according the the edited SMBIOS. Link to comment Share on other sites More sharing options...
//Zztony Posted January 5, 2018 Share Posted January 5, 2018 Hi, can I ask which PCI-E Bluetooth/WiFi card you bought and if you ever upgraded / installed High Sierra 10.13.2 with everything working OK re USB / Audio etc? Thanks//Zztony Link to comment Share on other sites More sharing options...
