Fix: Avoid potential delay in calc of RAM (darwin)

[aftaylor2]

The system_profiler command used to determine the total memory on darwin systems performs an "Activation Lock" check. This can produce a delay in returning total memory. I began experiencing delays of around 10 seconds.

Switching from system_profiler to sysctl to calculate total memory bypasses the "Activation Lock" check / timeout scenario.

Results of "time" command using system_profiler:

system_profiler SPHardwareDataType 0.17s user 0.23s system 3% cpu 10.165 total grep -a "Memory:" 0.00s user 0.00s system 0% cpu 10.164 total awk '{print $2 $3}' 0.00s user 0.00s system 0% cpu 10.163 total

Results of "time" command using sysctl:

sysctl -n hw.memsize 0.00s user 0.00s system 83% cpu 0.004 total awk '{print $0/1024/1024/1024 " GB"}' 0.00s user 0.00s system 86% cpu 0.004 total

I forgot to include the associated error message when experiencing the timeout:

2023-12-15 10:36:11.989 system_profiler[12578:260685] Timed out waiting for the Activation Lock Capable check

Awesome, I much prefer this solution anyways. Thank you for the find and the contribution!
