Screen stuck on dimmest setting
Hello,
My iMac is currently stuck with a dim screen, and changing the brightness does nothing at all. I have tried resetting the SMC and PRAM, and the issue is very briefly fixed after a PRAM reset, however the screen dims about halfway through the boot cycle. Any idea why it may be doing this, and how I can resume full brightness?
Many thanks!

Thanks for your replies. As an update, I thought I'd try a few different combinations. I reset the PRAM and immediately booted into safe mode. To my amazement the screen has stayed at full brightness, even when I restart and boot normally. No idea why, Macs still continue to baffle me!
