    Turn on -> Chime -> Loading Bar -> restart then Distorted chime -> some words like '' panic (cpu 0 caller 8xffffffff.......) Kernel trap at.... -> restart

    And this goes round and round, i tried Command + R but it doesn't react.

    Is there anyone who had this issue and found a solution?
    Thanks!

    It could be anything from a failed hard drive to a failed logic board or GPU to a software problem. You'll have to get it checked out and diagnosed you just haven't given enough information for anyone to diagnose it here.

    What kind of Mac?
    What year was it made?
    What is the OS you're using?

    You have a Kernel Panic. It could be hardware, it could be software. The following article has tons of useful info for you: https://support.apple.com/HT200553 You'll probably need to move past the first part of the article to find what's most useful for you, the section on "Troubleshooting a recurring kernel panic." They do need to update references to Mavericks in places - it's good for all versions subsequent to Mavericks as well.

    It's the very newest one,

    Took it to an apple store, even the genius wasn't sure what it was, might have been a failed hard d. Which is strange because i really didn't expect it to break down after only 4 months. I though that was how windows computers work, not the apple ones.

    It was the newest iMac with the highest configuration available online, that's why i was so panicked - i didn't expect it to break down this quick. It's at the apple store now, will see the results in few days but thanks!

    Thanks for the article! i did try all the steps when i still had the computer but it'd restart itself every 1 second after the Chime so i couldn't even get into the safe mode or the internet recovery.

    Any hard drive can fail at any time operating system has nothing to do with it. If it is only 4months old just get Apple to fix it it's free.
