iMac sleeping "too much" since last update

[DarknessUK]

I have an old iMac - 27 inch late 2012, but it works fine for what I want it to do.

Last Sunday I got a Mojave update automatically and since then when my iMac goes to sleep, when I wake it it is not out of sleep, but it looks like it has rebooted - but it has not!

The login screen has my account and Guest account - normally it just shows my own account

When I pop in my password, the desktop loads as per a reboot, external devices (hard drives) appear one by one over the next second or two.

Any applications I left running start up again, they have not slept at all, in the sense they were just running in background, but start afresh.

Any thoughts?

A couple of things:

The App store updater sometimes proves to be troublesome. There are reports that it sometimes doesn't run the firmware update that many older Macs require.

Download and run the Combo Updater.

This was released, taken offline a couple days later and rereleased. Even if you did it before, try it again.

Thanks - thought this had sorted it after a couple of reboots - but been out / come back and looks like back to before.

Thanks for replying though!!
