Bootcamp fked up during partition and macos disk utility disk utility simply sucks.

Now i have unaccessible 44gb space on this system. Also TIL, online help related to issues on Mac is terrible. Lol even stackexchange has no replies.

Apparently it seems i have to reinstall whole OS to recover it..

Or is there any other way?..

Why do you even buy from Apple?

Restart into single user mode. (Command+S keys). At the prompt type: /sbin/fsck -fy

When it’s done, you’ll see a message saying “** The volume [name] appears to be OK” if everything is fine.
If it found problems, you’ll see a “***** FILE SYSTEM WAS MODIFIED *****” message. This indicates the fsck command found and fixed problems. Apple recommends you run the fsck command again if it found and fixed problems.

When finished with all this type: reboot

See if it fixes shit, often better yhan disk first aid.

@helloworld did that. It said "appears to be ok". Didn't say anything about modified.

When i boot up, i still have that space unaccessible.

Okay I have no idea how to fix your issue but please for the love of everything holy you have a Mac just screenshot and text yourself the image don't take pictures with your phone

@Gatgeagent i bought into "macs don't hang" and most of all wanted a change. It was all bullshit. People who say Mac don't hang must be thinking girls don't fart / poop.

@HoloDreamer Macs are solid. I would back everything (exact copy) up to an external using something like superduper (http://shirt-pocket.com/SuperDuper/...). Re format hd then chuck it all back.

Boot with a Linux live dust to and do stuff with GParted!

@linuxxx distro* motherfucker I hate my smartphone keyboard sometimes...
