Recently, my bootcamp partition crashed. And then I start realising extremely slow performance on my macOS side to the point is as good as unusable.

Every click results in a spinning beach ball. At first I thought it was a storage issue, which is weird cause I have 30gb still on my mac partition. These are the stuffs are I did so far

- I deleted bootcamp partition, tried to merge it back to mac but it crashed
- Bootcamp is gone but it doesn't get merge back to macos
- I deleted alot of big files, now i have extra 300gb
- Problem still persists
- I tried checking my processes through terminal, nothing unusual.
- I tried reset PRAM too
- I tried removing all applications to launch on startup.
- Kill all unnecessary processes

And my internet connection is slow on this computer. All my other devices connected to wifi works fine. My phone (android), my macbook, even my extremely old iPad.
 
OP:
Start by telling us which Mac you have.
What year was it made?
What kind of drive is inside it?

If you have a spinning hard drive, its quite possible that your drive is failing. The issues list is what you normally see when a drive fails.

Make sure you have a backup of your data

As others have said it is likely a failing hard drive, but in case it is something else it would be helpful to know details of your setup.
 
Your next step should be to:
1. Boot to the recovery partition
2. Open Disk Utility
3. Run DU's "First Aid" option on the fusion drive.
What results do you get?

Run SMART Utility on it and see what it says. It has a free trial period. Disk Utility is useless for diagnosing drive issues.

Ahh i wish i saw ur message before i tried to reinstall macos. Currently my screen is stuck at a loading bar which shows full but not doing anything. Should i continue to wait?

How to know if it is still progressing? I search somewhere it says use Command L to see the logs but nothing happen, does this mean my computer has hang?
 
Do you happen to have an SSD, even a small one, around someplace?
I'd suggest trying to install a copy of the OS onto it.
Then use it to boot up the iMac.
See how it runs that way.

It's cmd V that shows the status messages.

I tried cmd V, it doesn't show anything, is it safe to assume my comp has totally fail to start up? Im not even sure if the macOS has successfully installed and that now my comp just fail to startup. (i went to sleep while the macos was reinstalling)

Good idea, totally forgotten about this. I guess i'll have to find one, doesn't have to be a ssd tho right?

Thanks guys, this is driving me crazy, and i got a hard deadline!
 
"Good idea, totally forgotten about this. I guess i'll have to find one, doesn't have to be a ssd tho right?"

It can be ANY kind of drive.
It can even be a USB flashdrive, so long as it's 16gb or greater in size.

The idea is to have an external drive (of some sort) that is FULLY BOOTABLE TO THE FINDER.
Once you have a tool such as this, diagnosing problems can become MUCH easier.
