[massimilianofurlan]

Julia Version 1.7.0 (2021-11-30) for ARM
2021 MacBook Pro (M1 Pro)

Running

using SharedArrays
arr = SharedArray{Tuple{Int64,Int64}}(2)

results in

System max size of single shmem segment(MB) : 4
System max size of all shmem segments(MB) : 16
Requested size(MB) : 0
Please ensure requested size is within system limits.
If not, increase system limits and try again.
ERROR: SystemError: shm_open() failed for /jl005263QYtt4T0wCXAsXvchp9kI: Permission denied

The same code works under Rosetta2
