2010 and 2011. They are both long gone, I hauled them off to the recycle service last year. My 2007 finally died this year, last OS was El Capitan and it never crashed, PS finally died so it's gone too. It was a great iMac.
I use Logic Pro a lot. I have nine years invested in that DAW. It's the best DAW I've ever used and I was fully prepared to pull the trigger on a new iMac Pro, but now that I know the same crashes are happening on it, I am convinced it's a system wide problem, ( I have no proof, just a gut feeling and two crashed iMacs) I've been 9 months downtime now for recording, so I'm a little upset(lol). When I read all your threads i pretty much knew I had to walk away from Apple. I've poured over every article and forum I can find. No fix on the horizon and cricket noises from Apple. The only way to reach Apple is buy a Dell. I hate Windows, but my son, who's way smarter than me, is running Ableton Live on Win10 and he says it's rock solid, so time for this old dog to learn new tricks. I used MSFT from 1983 to 2007, switched to MacOS, had a great run for nine years and now that run is over. If Deadmau5 can run Ableton on Win, so can I.... a lot of studios are going back to Windows 10 as well, so I know it's not just me having a problem. Apple doesn't care, I'm now convinced....
I hope you solve your problem, thanks for sharing your info, you saved me from a $5000 nightmare......
Is Deadmau5 your son?
