That available column in free output just comes from MemAvailable in /proc/meminfo. I don’t know of any other MacOS utility providing that available-memory estimate.įor the sake of comparison: On a Linux system, the same sort of information is provided in the available column in output from current versions of free: total used free shared buff/cache available Notice the Available row, which shows an estimate of how much memory is actually available for starting new applications, without swapping. The output it produces looks like this: MEMORY I think these days, psutil and its meminfo.py script provide the most helpful memory-usage details. Ideally, if you just want RAM then issue: $ hostinfo | grep memoryĭon't know if hostinfo exists on any previous OSes though. The good this about this command is that it comes preinstalled with the 10.9 installer too under /usr/bin, so it's very handy, Kernel configured for up to 4 processors.ĭefault processor set: 195 tasks, 961 threads, 4 processors Just use the command "hostinfo", here's the output from my mid 2012 MBAir running Mavericks (10.9.1): Mach kernel version:ĭarwin Kernel Version 13.0.0: Thu Sep 19 22:22: root:xnu-2422.1.72~6/RELEASE_X86_64
FREE PROGRAM FOR MEMORY MAC MAC OS X
If you've booted from a Mac OS X start up disk, then all the above solutions obviously won't work.
FREE PROGRAM FOR MEMORY MAC INSTALL
The above is way too much effort for my liking, and it assumes that you have a fully fledged install too.
(very slightly adjusted to match the tab sizing on StackExchange ) Here's an example of the output of the script on my system: % memReport.py
The script also counts up the "real memory" usage of all running processes for comparison (this won't match any specific value(s) from overall memory stats, because memory is a complex beast). Print('Real Mem Total (ps):\t%.3f MB' % ( rssTotal/1024/1024 ))Īs you can see, you can just call vm_stat from the command line, though it counts in 4kB pages, hence the script to convert to MB. Vm = subprocess.Popen(, stdout=subprocess.PIPE).communicate().decode() Ps = subprocess.Popen(, stdout=subprocess.PIPE).communicate().decode() If you want it on the command line, here is a Python script that I wrote (or perhaps modified from someone else's, I can't remember, it's quite old now) to show you the Wired, Active, Inactive and Free memory amounts: #!/usr/bin/python
As says, you can see this info in Activity Monitor.
