Port Status
The Mac OS X port is a Tier 3 Port, though it can run with some significant headaches.
The main branch will compile on macOS Monterey (12.6.8) on Intel, and it can run if the kern.sysv.shmmax parameter is correct (see below). Launching new interpreters can be hit-or-miss, as there are shared memory issues on this platform. You may need to try starting a new process 10 times or more before one will launch successfully.
FreeM Lite works correctly on this platform, bugs in that release notwithstanding.
Verified Releases
Build Notes
In order to build FreeM on macOS, you will need to install the following:
- Apple XCode command-line tools
- Homebrew
Then, install the following with the brew package manager:
- automake
- autoconf
- gcc
- libtool
- texinfo
- texi2html
- git
Testing Details
We build the macOS port on the following hardware:
- MacBook Air (Early 2015) running macOS Monterey (12.6.8)
Required Kernel Tuning
You will need to set the kern.sysv.shmmax sysctl parameter to at least 6144000 (the value must be a multiple of the system page size; generally 4096).
To determine the current setting, see below:
$ sudo sysctl -a | grep shmmax kern.sysv.shmmax: 4194304
In the above example, the shmmax value is 4194304, and thus insufficient for proper FreeM operation.
See your macOS version below for instructions on modifying this value.
macOS Monterey
- Find the file
com.startup.sysctl.plistfile in thescriptssubdirectory of the FreeM distribution - Copy it to
/Library/LaunchDaemons - Change the ownership of
/Library/LaunchDaemons/com.startup.sysctl.plisttoroot:wheel - Run
sudo launchctl load /Library/LaunchDaemons/com.startup.sysctl.plist - Reboot
See the following example:
$ sudo cp scripts/com.startup.sysctl.plist /Library/LaunchDaemons/ $ sudo chown root:wheel /Library/LaunchDaemons/com.startup.sysctl.plist $ sudo launchctl load /Library/LaunchDaemons/com.startup.sysctl.plist
Starting the FreeM Daemon Automatically
Coming soon.
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.
