Mosek.jl is not compiling in Julia 1.8 macOS ARM (M-series Processor). It is unable to load libmosek (~/.julia/packages/Mosek/3NJdY/deps/src/mosek/9.3/tools/platform/osx64x86/bin/libmosek64.9.3.dylib).

It is probably an issue with Apple Silicon M1 not supported by Mosek 9.3. Recently released Mosek 10 natively supports Apple Silicon M1.

Yes, you cannot use Mosek 9.3 on M1, and MosekTools.jl doesnt support Mosek 10 yet.
