And indeed, I also know little or nothing about iMacs, and so BIOS may well be the wrong term, but there must be some sort of firmware for booting and handling low-level stuff. Nevertheless, should Macs not handle the low level stuff the way a PC BIOS does, then my bet is on some sort of hardware problem.On Sun, 20 Mar 2016 05:28:55 +0100 Jerome BENOIT <sphericaltriangle@rezozer.net> wrote:Hello Forum: On 20/03/16 04:42, Michael Milliman wrote:On 03/19/2016 09:40 PM, lina wrote:shutdown -h now doesn't work. it still reboot.This sounds like an issue with the hardware or BIOS not with the Debian OS, or with the Desktop environment. Though I have not had this problem, I have had several others related to shutdown/reboot/suspend/hibernate on various machines, but I know for a fact that all such problems have been with the hardware/BIOS, not the Debian software. I don't know enough about the iMac to offer anything more.Does recent iMac have a BIOS ?What do you mean by this? Of course Macs have *initialisation firmware* (about which I know nothing) but not necessarily MBR BIOS as seen on PCs.
