Apple’s Worldwide Developers Conference to kick off June 10 at 10 a.m. PDT with Keynote address

The Keynote will be available to stream on apple.com, the Apple Developer app, the Apple TV app, and the Apple YouTube channel. On-demand playback will be available after the conclusion of the stream.

Looks like no one’s replied in a while. To start the conversation again, simply ask a new question.

Imac will not restart

Older iMac (2016?) was powered down and will not restart.

I tried the usual fix, safe mode, but it stalls and recovery into Disk 1st aid, but that failed

Can you run Apple diagnostics? https://support.apple.com/en-us/HT202731


If that doesn't run or show problems my next suggestion would be to reinstall MacOS. Preferably from a Time Machine backup I recommend everyone have, or alternatively from Internet Recovery.
