I have the Mac mini 1.4 and notice that often times it will get quite hot, like when I do several apps or browsers at one time. Becomes very erratic when doing functions, cursor is uncooperative. Have to restart
(after a cool down period). Is this normal for this machine, or signs of an issue? Otherwise, it is a great toy.

Blow the vents with compressed air. Also check what apps are running that's using a lot of the cpu.

Yes. More than likely one of the apps is too CPU extensive. Some video files can do that at times.

Note that "blowing" vents can overspeed your fan and potentially blow it up. I used to do this with PCs but I'd remove the cover and hold the fan with my finger. This might not be end user doable. (I'm an engineer and electronic hobbyist, I can do stuff that most people can't, but looking at my notebook I wouldn't want to see what's inside.

Depends if your iMac is old or new. If it's old then possibly dust cloggery. (Look, I invented a word! ) There is also a thing I'll call accumulated obsolescence. It goes like this and applies to most computers, tablets and phones:

They come out with a new, more powerful model. This allows software developers to write more demanding apps and programs. They keep doing that and the new apps and programs require more processing power. Eventually the upgraded software is just too much for the old computer. The CPU starts running hotter because it's running pedal to the metal all the time. That's the time when you have to upgrade your computer to a more powerful model that wasn't yet invented when you bought your old one.

And then the cycle repeats, more powerful computer, bigger apps, they clog your old computer, you have to get a new computer. Wash, rinse, repeat...

So IMO it's obsolescence or clogged ventilation, unless it's new, and I suspect it is not. If it's new, don't ask me!

The 1.4 turbos pretty high and is pretty underpowered otherwise. I have one that does basic duty. I replaced the HDD with a SSD but that is NOT for the faint of heart as you pretty much have to disassemble the whole thing.

You’re limited what you can do so gently blowing out any dust may help.

I gotta have SDD on my next laptop! I'm drooling!

SSD is cool in both meanings of the word.

You could always buy your SSD then take it to a computer guy to get it installed. Replacing the main drive in a laptop is difficult because you need all the drivers and system install media, but an expert could possibly copy the old HDD onto a new SSD and then do the mechanical swap. Should work.

The most I've done on my laptop is replace the keyboard several times. However I'm fairly experienced in working on computers; this is my first laptop. Desktops were sooooo easy. Not so with laptops.
