The only downside is that if you ever reset your NVRAM, you will need to run the nvram command again to turn performance mode back on. This is a much better way to increase your system limits because it increases all the interrelated limits in a consistent way, taking into account the capabilities of your specific computer. Most importantly, systemwide limits will also increase so that a single rogue user or program will not be able to crash the system through resource exhaustion. The new limits depend on how much memory you have and require you have at least 16 GiB of memory installed, but at a minimum, you will see your user limit on the number of processes you can run increase from 709 to 3,750 and many other limits are increased. This is officially supported by Apple, and changes the default configuration of your computer from an interactive computer you are going to use for email and web browsing to a server you are going to use to run a lot of non-interactive software. To do this on El Capitan (and later macOS versions until further notice), you do not need to create new files or mess with turning SIP on or off, all you need to do is $ sudo nvram boot-args='serverperfmode=1 $(nvram boot-args 2>/dev/null | cut -f 2-)' 'Server Performance Mode' or perfmode or serverperfmode).

If your computer is routinely bumping up against process limits and it is not due to some runaway program or malware, then instead of trying to override the defaults, you should switch to a different set of defaults known as 'Performance Mode' (a.k.a. So, what is the right way to fix 'Too many open files' or 'fork: resource temporarily unavailable' on OS X El Capitan? The other issue is that if 709 processes was not enough, 1000 processes is really unlikely to be enough either. I found similar suggestions regarding the maximum number of open files maxfiles and maxfilesperproc, which are even more dangerous, because a single process should get nowhere near being allowed to open the systemwide limit on the total number of open files. It is therefore very important that no user be allowed to create enough processes to fill up the process table, which is why on the Mac users are limited to 2/3 of the total number of processes. When the system hits the maximum number of processes, it generally crashes quickly and in a very bad way. What it means is that the entire system is still limited to a maximum of 1064 processes, but an individual user is allowed to create more than that. Which would be great, except $ sysctl kern.maxproc I did that and rebooted and now $ ulimit -u I was able to confirm this by running a shell as root: $ id -ru I was hitting the systemwide limit kern.maxprocperuid. And the error message did not start with -bash so it was not about ulimit either. OK, I could not run that command, which creates 3 processes, so I was probably at the process limit.

I tried this command, which prints out how many processes the user is running (actually 1 more than the number of processes) $ ps -xu $(id -ru) | wc -l $ ulimit -uħ09 is a lot of processes, but I was running a lot of servers on my Mac, so it seemed possible I was using that many. bash: fork: Resource temporarily unavailableįrom the fact that my system was not completely freezing or spewing errors all over the place, I expected that what was happening was that I had reached my limit on the number of processes I can run. I was seeing things like error: cannot spawn or unable to fork or -bash: fork: retry: Resource temporarily unavailable I ran into some problems on my Mac running OS X El Capitan 10.11.6 that appeared to be related to resource limits.
