Just installed Atom.
I have disabled and removed packages (emmet and pigments)
I create a new folder, with 1 file in it placed in the desktop. Once I start working immediately Atom slows down and the CPU usage for atom helper goes to 80% up to 100% sometimes.
Heres the weird thing. I can open another project that’s placed within applications/mamp/htdocs and even add a new file with the CPU usage staying around only 29% the most which are manageable
Also test restarting and using atom --safe ,and got the same results.
