Problem: Computer is too slow Description: Kernel_task taking unto 300% of CPU
Q - No Time Machine backup - Time Machine backup not found.
A - Under this present setup, this indicates any Persona Data is expendable and can be replaced. A Time Machine Backup is very useful

Q - Battery: Health = Normal - Cycle count = 1094
A - Batteries are considered Consumable Products. Over time it will degrade to a point where it needs to be replaced. The usage is normal as the capacity will go up and down all the time and never stay always at 100%. Apple Batteries are rated for 1000 Full Battery Cycles and / or 80% Capacity before needing Evaluation or replacement.
Q - Kernel extensions present - This computer has kernel extensions that may not work in the future.
Q - EnergyDriver.kext - com.intel.driver.EnergyDriver (3.7.0 - SDK 10.14)
A - This one I am not sure of as it appears to some Third Party extension that was installed. The Operating System is developed by Apple for Apple Computers and should be left to the Operating System to manage such functions.
MacBook Air Model: MacBookAir6,2 1.4 GHz Intel Core i5 (i5-4260U) CPU: 2-core
4 GB RAM - Not upgradeable
A - Running this computer with 4 GB RAM is doable. Though the machine will struggle to swap into and out of the RAM for most functions. This will further, be an issue, if the machine is running more than a couple of Native Apple applications at the sometime. It will lead to extra stress on the OS and will be a contributing factor with the Kernel_ Task Issue

A - Personal Preference for web Browser but judging from the amount of CPU Usages MS Edge is a really Resource and Memory Hog and again a contributor Factor in the Main Issue this computer is experiencing
A - Alternative browsers are Available and my not be as CPU / Memory Hogs.
I have seen suggested by More Senior Contributors www.brave.com which is like Google Chrome but without the Overhead of Google
