Hi,
I have made some tests (Julia 1.6.4) with a normal user account under Mac OS and Kaleido does not start,although it starts when the user is admin:
julia> using Plots
julia> plotlyjs()
Plots.┌ Warning: Kaleido is not available on this system. Julia will be unable to save images of any plots.
└ @ PlotlyJS ~/.julia/packages/PlotlyJS/4jzLr/src/kaleido.jl:65
PlotlyJSBackend┌ Warning: ErrorException("Could not start Kaleido process")
└ @ PlotlyJS ~/.julia/packages/PlotlyJS/4jzLr/src/kaleido.jl:66
Is is a known problem ?
S.
