I think you’d better use official binaries. It is simpler to have different installations. If works for me perfectly. JuliaPro is not really anything more than Atom+Julia
If JuliaPro is the same as usual official binaries: In the 2nd JuliaPro, Go to Packages > Julia > Settings and change "Julia Path" to point to the Julia binary. and point to the one which doesn’t use MKL.
