iMac won’t boot and stuck on full progress bar

Question

iMac won’t boot and stuck on full progress bar

My iMac was running smoothly until today, where I’ve noticed that it kept freezing and most of my apps became unresponsive.

Ive rebooted, and everything was running smoothly for like a good 10 minutes, then it suddenly became slow and increasingly unresponsive.

i then tried to reboot to safe mode, but right after the progress bar was complete, the screen became black and was stuck like this for quite a while.

i then tried to reboot normally, and now it gets stuck at a full loading bar and won’t load.

specs:

27” iMac late 2013 model, 8gb memory, 1tb storage, Mac OS High Sierra

I had to get this Mac repaired twice before, don’t wanna have to go through that over again.

Anything I can do to resolve this issue?

Ok so quick update, I’ve gone to recovery mode, gone through first aid, then restarted on verbose mode, and now I’ve managed to login back to my computer, which was quite a relief.

However, it is still running pretty slow, and I’m running through first aid again, and says this following error:

”error: (iOS 0x4ff73) apfs_root: btn: dev_read_finish(2645383, 1): input/output error

fsroot tree is invalid.

the volume /dev/disk0s2 could not be verified completely.”

Storage system check exit code is 0.”

Any suggestions?

I did try with safe boot, but after the progress bar was full, there was just a black screen with the cursor. I waited for quite a while but nothing happened at all.

I also tried to reboot on recovery mode and checked all disks with first aid, but they all seemed fine apparently.

I don’t really have an external drive available, so I did try to reinstall the Mac OS on my internal drive, and it restarted but now the progress bar is nowhere near halfway and will probably be stuck like this for a while.

Yea, I’m gonna have to back up all my files on time machine, or with an external hard disk. Turns out i need to replace my HDD drive with a SSD drive, which might help the Mac last longer.

Thanks for the help!
