kernel_task using way too much cpu After installing big sur, i noticed my 2017 macbook pro would lag every few hours, during the lag i basically cannot do anything because it was so laggy, but one time managed to open activity monitor when it was lagging and i saw kernel_task was using 400% or higher cpu, ive already tried to restart my computer but it just comes back after few minutes, ive also tried reseting my smc and unplugging my cords but it still didnt work, how can I fix this? (sorry if my english is bad, english is not my native language)
also, my mac's model id is 14,2
Your mac may be overheating, try switching the charging ports.
