tornado99 Posted August 5, 2015 Share Posted August 5, 2015 Hi, I have a Yosemite installation using the latest Clover. Sleep works fine (using darkwake=8). Waking with usb mouse/bluetooth keyboard turns the display on, the cursor in an open text document is flashing, but both the keyboard and mouse are frozen! Unplugging and replugging doesn't change it. Also, any usb drives attached have a dismount error. Can anyone help? Link to comment Share on other sites More sharing options...
WaldMeister Posted August 5, 2015 Share Posted August 5, 2015 Hi, Are you using a custom DSDT? And can you provide some hardware information about your system? Link to comment Share on other sites More sharing options...
tornado99 Posted August 5, 2015 Author Share Posted August 5, 2015 No custom DSDT. System is: Broadwell i7 5775c, Z97I Gaming Ack motherboard Link to comment Share on other sites More sharing options...
WaldMeister Posted August 5, 2015 Share Posted August 5, 2015 Found a possible solution on another board: Enter your UEFI BIOS Go to MIT-Advanced Frequency Settings > Advanced CPU Core Features > Internal CPU PLL Overvoltage Set this to Disabled otherwise you will lose all USB devices on wake Not all boards have this option, but my guess is it's bios related.

tornado99 Posted August 5, 2015 Author Share Posted August 5, 2015 Couldn't find that option, but found something called "Filter PLL", disabled that and OS-X wouldn't boot. The bios must "see" my USB devices as I can use them to wake up the computer, and turn the display on, but then they're frozen. Link to comment Share on other sites More sharing options...
