Wouldn’t you just pull the power cord at that point? If the device has become completely unmanageable such that it needs a power reset i’d be surprised if there’s much more harm that way than holding down the power button until it turns off.
I can’t remember where I watched it - but I saw some video a while ago now where (I think) the engineer was explaining that shutdown & power on does less of a cleanout than restart on Windows. Something to do with shutdown going through steps more similar to a sleep/suspend than restart. Made little sense to me but would be interesting to see if post restart or post power-on the computer was “fresher”
I wonder if power buttons are a Windows thing? I recently switched to Linux on my desktop and have a MacBook as well. On the MacBook i’m not sure if i’ve ever used the power button - it just goes to sleep & I wake it up.
And on Linux the suspend is so good I don’t power off at all, but on Windows I always did so needed the power button all the time.
I still have one of these, I bought it & set it up as a server 14 years ago so its been powered on the majority of its life, and still functions ok. I’ve slowly moved most stuff off it and now it kinda just exists as a computer to buy & download albums from iTunes on if I can’t get them on bandcamp etc.
If I didn’t need OSX for the iTunes part i’d have rebuilt it a long time ago with some more lightweight linux distribution but its doing a job and now i’m reminded of how old it is I kinda want to see if I can get it to 20 years.
i’m becoming a linux nerd and this power button thing would be fine for me bc ive discovered how good suspend is and never power off my desktop anymore anyway, just spend then bump the keyboard when i want it back.
