So recently my Late 2015 iMac has been 50/50 at best on whether it will wake once put into sleep. When in sleep if it fails to wake up the screen stays entirely black, not even attaching a wired keyboard etc will wake it up, holding down the power button on the back of the machine does nothing, only be literally pulling the plug can I get it to 'switch off' so I can turn it back on again.
ive reset the SMC, VMRAM and completely erased my hdd and reinstalled Catalina but still have the same issue, any help would be greatly appreciated!
