![]() That way it only uses 'half power' at compile. One way I've used in the past for compiling with fewer cores is to run a VM of the same OS in Parallels & assign it only the number of 'real' cores your Mac has. Whether you are actually suffering an overheat shutdown or a power-starve shutdown is hard to tell from just that data. The issue is your Mac can't keep itself cool enough on battery power whilst maintaining 98% busy either the battery is weak, or there's insufficient airflow. The figures at the bottom are for the entire CPU, which definitely shows it's fully 98% busy.Ĭompiling always uses as many threads & cores as it can. 1000% therefore would imply 10 cores are fully utilised The 1000% figure, btw, is because in the top part of Activity Monitor, 100% is 'one core'. Please help me out with this as it's affecting my work and efficiency. I found a lot of questions on CPU spikes till 300 percent and their solutions were all directed towards checking for third party apps and hardware issues or optimising android studio. Factory reset Mac and reinstalled macOs CatalinaĬurrently my laptop has only two third party softwares - Chrome and Android Studio.Tried experimenting with increase in heap sizes.Tried building a basic Hello World project (CPU for java still spikes till 800%).Mac performs very normal on any other work be it browsing or video calls or streaming.(This is what make me confused since I am not quite sure if it was a shutdown actually, everythin points out to that because fans are paused, screen is turned off, touch bar & keyboard lights are turned off, the mac remains exactly as if it were shutdown but it is turned on suddenly after 1 minute to continue doing what it was doing before this happened, which is so weird) The Mac shutdowns for around 1 minute and then is turned on again and continue doing the task was doing previously. ![]() Strange thing is, if the mac is in charging mode, it doesn't shuts down while if it's not, it shuts down. ![]() As soon as I build a project, there comes a time when CPU usage for a java process spikes to more than 1000% (screenshot attached) and sometimes upto 1500%.Android Studio IDE works all good and normal while I code.It's been 2 weeks now and I have been trying to find the root cause of this.Ĭonfiguration: 16GB - 256GB - 15 inch Macbook Pro 2019, 2.4 GHz with 8-Core Intel Core i9 - macOS Catalina - Android Studio 4.1
