How come a Mac Mini with 4GB of RAM is MUCH MUCH faster than an iMac with 8GB of RAM!
When the rest of the specs are identical ...

@M1sf3t Nope, both almost have the same software installed, I tried clearing cache, disable startup items, even set background to black color, still iMac is a pain :\

@M1sf3t I am not sure tbh, mac mini is using HDMI while iMac as you know the built-in screen, would this make a difference?

@irene it could but I don't think it is heating up from the moment it is turned on, its like this all time

@M1sf3t lool I'd expect the same

@irene I need to check for cleaning, but I saw on iFixit how to remove the screen, I don't want to break anything that thing is not easy to dessemble

Do some proper testing. Open up Activity monitor. Measure the cpu and ram usage.

Look for unusual spikes and look for which programs are using more than they use on a concurrent machine and so on.

You need to troubleshoot the problem because "identical specs" doesn't say much. It might even be as simple as a difference between HDD and SSD. Or a different motherboard in one of computers which doesn't utilize your SSD fully.

@gitpush Which resolutions are you running? Are any of them scaled? :)

What I've learned from 3 years of mac using - scaling is a bitch. Native mac resolution is it's mom.

Why?

Well... Try plugging in a 4k monitor to a mac via thunderbolt/hdmi. It works perfect, no heating, no issues. Now try to scale it... Shit gets loose and everything is unresponsive. Pc constantly overheats.

Now... Plug in a non-scaled display to a scaled original display - and you'll have the same shit.

Even more.... I'm using a laptop... My collegue runs a 1440x768 resolution (native, non-scaled) and I run 1920x1200 (can't bare the smaller one, too big shit). You know what? His temperatures are lower, battery lasts longer....

@zemaitis @M1sf3t @irene @potata it turned out because of this: https://devrant.com/rants/2131945/...

@irene in other words Facebook, it is for watching files for changes so that it auto reload website/react native app ...etc.

I still don't know why it auto starts
