Hold down power button for 15 seconds.

If I that doesn’t work, unplug it. Wait 30 seconds. Restart.

If you have <8GB RAM, upgrade to 16 or more. https://eshop.macsales.com/shop/apple/memory/iMac (They have installation videos even a kid can follow.)

Meanwhile, run Disk Utility —> Disk First Aid on all drives. Let it repair what it can.

Reset PRAM — Cold boot your Mac WHILE you hold down Option + Command + P + R until it has restarted three times. Then let go.

If none of this helps, visit the Genius Bar at an Apple Store, or find an independent Mac repair shop with a great rating on Yelp!.

Press the Power Button until the system shuts down. You will be given a choice as to whether you want the apps you were running to open again. Where is the Power Button? When looking at the front of your iMac, put your finger on the left hand backside of your computer. The power button is located roughly 2-inches in from the far left hand side and 2-inches up from the bottom edge. When looking at an iMac from the rear, you’ll see the power button in the lower right hand corner

every once in a while the same happens to me. i force the shutdown using the power button method. starts up and works fine. i have 16 gb ram. the computer is a 2012, so there may be some other compatibility issue given the age of the computer. I dont have any issues with my Macbook pro,

I have noticed somewhat of an oddity. This has cropped up with the last three system upgrades (27" iMac mid- 2014 model). After downloading the upgrade and allowing it to install, the computer restarts as part of the installation process.

Then, off I go, merrily using the machine for various tasks. But EVERY time, I encounter problems - drives showing as containing zero files when they have LOTS of files, other various software oddities. and so on - and these things persist - until I click on the Apple menu and select "Restart."

Rebooting the machine eliminates the oddities. Don't know why this happens, but it does. May be an anomaly in my machine, may be left-over bits of the previous system still trying to come into play, whatever. But a restart seems to clear up the issues every time.

One wonders whether anyone else has encountered this.

I have also noticed then since upgrading to Mojave my computer seems to run slower especially when trying to upload photos,

I've also noted that, after upgrading MacOS to the newest version, after the computer restarts, Drive Genius reports one or more drives as having multiple damaged sectors. DG then recommends backup and replacement. (These are the ones that show no files, when files are actually present.)

But after a reboot, as mentioned above, the drive warnings disappear and all drives report as good and fully functional - and all files appear as before.

Like I said, one wonders whether anyone else has noticed such behavior.

I’ve run Mojave since December on my late 2013 iMac with zero issues. However, it is a virgin installation on a new 2 TB SSD. I migrated all my data from the old 5400 RPM hard drive, and installed the latest versions of my software.

I do this “virgin installation ritual” every three years, just because it cures all kinds of weirdness. This time I doubled RAM to 16 GB, and doubled startup drive space to 2 TB using a super-fast SSD. Boot time is 40 seconds, including login.
