    Hi guys,

    Is it dangerous to run my macbook pro at very high CPU for a few hours?

    I use a DJ application called Serato that needs to analyse my iTunes library first before I can use it. This process can take a long time if you have a large music library. I noticed that when I was analysing songs, Serato was using 180% CPU so I stopped it immediately. I contacted Serato and they said this was perfectly normal when analysing songs.

    Is this safe??? :confused:

    Yup, nothing to worry about. I sometimes encode videos for hours on end, no issues.

    Is that from Activity Monitor? I understand how 180% might seem startling, thinking that 100% is the maximum normal operating limit, but it's fine. If you want a number that makes more sense in this way, download MenuMeters and check the option to "show average for multiple processors as single display." This will give you an actual 0 to 100% reading averaged across cores.

    Lol, i transcode stuff on my MBP, and it runs up to 790% (8 virtual cores) under handbrake for half-hour at a time, just fine.


    The machine is made to be able to run like that, don't worry about it.

    my machine runs up to 800% since there are 8 virtual cores... it all depends on how many cores you have.

    if you're worried download SMC fan control then set your fans a little higher than they want to run when under load, it's also good for when you have the MBP on your lap so you don't roast you balls off

    It will burn it up... too bad, you'll have a broke computer due to pirated music libraries...

    OSX way of reporting CPU load is just ridiculous.

    I was making a joke! Try rendering some 3D... if that won't tax a box nothing will! But I'd be careful of pirated music, some music can have imbedded tags in it to make your CPU burn up...
