    Hi guys,
    My Macbook Air, particularly in the morning first thing, will randomly freeze, even when I know that there is lots of battery available. I will plug the adapter in, and hold the power key, and then it will come up with the low battery symbol. Is the battery indicator suspect under Mojave?

    I am not sure about the battery indicator, but since my upgrade to Mojave, a have been having a lot of unexplained shutdowns. Nothing orderly, the screen goes black, sometimes with a cursor remaining and sometimes not. Hard reset is required to restart.

    I have noticed the CPU temperature spikes as high as 200 degrees F at the drop of a hat, and can fall just as quickly. I suspect these crashes may be thermal shutdowns, unannounced, and unreported. When I unplugged all USB devices, things got better. Running a lot of software at once does drive the CPU temp up so there could be a problem with power control at the CPU. I hope this helps.

    Hi Douglas, thank you for the reply. In my case it seems to be related to the battery indicator. I turn it on and it says 35%, two seconds later it shuts down and then when I plug it and restart is show 0%.

    @Bishop200 and douglasgoodall: Can you tell us the Apple computer model/Year and if you did a clean install or upgrade?

    Macbook Air mid-2013. Upgraded rather than clean install.

    If it was a recent upgrade your might still be in the process of spotlight indexing. If not, I would backup the data and try a clean install and do not import any apps from your backup. See how the clean install goes. If the problem persists then, it may a hardware problem. If the problem disappears with a clear install, check the compatibility of any application before you import them back to your computer.

    What prior OSX did you have before upgrading to Mojava?

    Well, that's interesting. I assume you did an upgrade for HS; so why is Mojave shutting down? Maybe insufficient RAM?

    I haven't had the opportunity to do a clean install yet Madrich. It usually happens when not much is running when I close the lid.

    If after the clean install the problem persists I would take it to an Apple Store Genius to run Apple Service Diagnostics.
