    I just got my MBP 2018 15 inch base spec model with 512 gb SSD upgrade.

    The day I got it I upgraded the OS to Mojave.
    since then, I kinda feel my MBP got slower..
    (even my Garage Band kind of lag when I'm trying to open some charts)

    I'm not sure if this is normal or is because of Mojave..

    When I make music with Garage band,
    even though I didn't use any crazy heavy instruments
    ( I only used a few stock instruments just to play around with it, with some few drum wavs )
    It produce some heat..

    is this normal ? if this machine can't even take a little work without getting all heated, how am I supposed to work on some more heavy project ?

    IIRC, Garageband utilises Metal, so that will kick the dGPU into action and be hotter as a result.

    It shouldn't be laggy though. I've only got a 2012 15" and that works okay with LPX. Heat doesn't necessarily mean overheating. The chassis is metal to disperse heat, so it might feel hotter to the touch but the internal components will still be within their thermal limits.

    I heard that any activity using the dGPU (even as simple as connecting an external monitor) will result in the machine running hot and fans kicking on. If I buy the 15", this will be something I have to get used to as I don't think it happens as much with the older generations. Not sure if its related to the 6-core 8th gen processor or the T2 Chip, but there's been quite a bit of issues with the 2018. Hopefully they can fix it as I am interested in purchasing one in the upcoming month.

    As noted, heat is not necessarily an issue. I use Garaband on my dual core and I don't find it hard on the CPU at all. I'm usually just using two tracks at a time.

    I would check Intel Power Gadget and the Activity Monitor to see how hard it's working and how warm it's getting.
