Platform Notes (Mac OS X)

Port Status

The Mac OS X port is a Tier 3 Port

Verified Releases

TBD

Testing Details

The macos-fixes branch will compile on macOS Monterey (12.6.8) on Intel, but the default shared memory size on this operating system is too small to accommodate the default FreeM shared memory segment size. Reducing the segment size results in the following error:

freem [FATAL]: memory allocation failure in job_init [errno 2 No such file or directory]

Port Challenges

Apple makes it extremely difficult to build traditional UNIX software, in the name of "security". Also, Apple silicon (M1 and descendants) cannot likely be supported with the current shared memory architecture.

We will most likely support only PowerPC and Intel Macs.
