Bug description

MAC 14.3.1 (23D60): Audacity Silicon is constantly crashing due to QSharedMemory::create: out of resources";
Alle version from SILICON / Intel are crashing only the good old: Only the version 2.4.2 works fine on newest Mac Sonoma.

The output from Terminal when starting any newer version is:

"SingleApplication: Unable to create block.
SingleApplication: 7 "QSharedMemory::create: out of resources"

==> AND NO: REBOOTING DOES NOT FIX THE ISSUE! It returns constantly.

The only hint i found, but is is catalina and not Sonoma and i have a fresh and new Sonoma machine right from the start is the following link:

Please fix the bug the quickest possible for all Mac user using SONOMA. Thx.

Steps to reproduce

Terminal:

./audacity.app/Contents/MacOS/Audacity

Expected behavior

App should start but instead:

"SingleApplication: Unable to create block.
SingleApplication: 7 "QSharedMemory::create: out of resources"

Actual behavior

A crashing audacity app from the newest version back to version 2.4.2: This is the only one running properly on Sonoma 14.3.1

Audacity Version

latest stable version (from audacityteam.org/download)

Operating system

Steps to reproduce
Terminal:

./BitBox.app/Contents/MacOS/Audacity

What is BitBox anyway? @vigilant4u

@dozzzzer a crypto wallet thingy which also has the same issue: BitBoxSwiss/bitbox-wallet-app#2562

@vigilant4u I'm strongly suspecting you have some program running on your system which is eating up all shared memory segments. Audacity requires just a single one to start, and if something else has eaten up all shared memory segments, it can't. Given that a restart doesn't fix it for you, it'll be a program that's automatically loading on startup for you.

Bitbox is another app with the same issue: They are already working on a fix, see here:

definitely not!

Shared memory is a separate concept to RAM. I believe the terminal command to list shared memory segments is ipcs -m, with the nattch column listing how many segments are attached to a shmid, and ipcs -m -p to show which creator process has made the segment, and ipcs -m -l listing the limits the system has. I believe macOS comes with a 32 segment limit by default, which is extremely easy to fill up by misbehaving programs which need to share large amounts of data between processes.

The Only way i got Audacity 3.4.2 Silicon app to run properly on Mac OS Sonoma 14.3.1 was writing an executable apple script to be executed on Login Items during the startup process as followed:

As there is definitely a shared memory bug on Sonoma 14.3.1 preventing to let your app start when the default values influencing the default shared memory settings

kern.sysv.shmmax
kern.sysv.shmall and
kern.sysv.shmseg

would stay as defined by apple, the only workaround is as followed:

open ScripEditor:

tell application "Terminal"

if not (exists window 1) then reopen
do script "sudo  sysctl  -w  kern.sysv.shmmax=104857600" in front window
delay 0.5 --pause for half a second
do script "roae3o7snapokatMZ" in front window

if not (exists window 1) then reopen
do script "sudo  sysctl  -w  kern.sysv.shmall=25600" in front window
delay 0.5 --pause for half a second

if not (exists window 1) then reopen
do script "sudo  sysctl  -w  kern.sysv.shmseg=4096" in front window
delay 0.5 --pause for half a second

if not (exists window 1) then reopen
do script "sysctl -n machdep.cpu.brand_string" in front window
delay 2 --pause for two seconds

if not (exists window 1) then reopen
do script "sysctl -a | grep shm" in front window
delay 8 --pause for eight seconds

quit

end tell

Hope this also works others.

PS:
I have no clue why it works on your side guys as i have used a fresh preinstalled Macbook Pro M3 with Sonoma.
I only installed the latest security update 14.3.1 from end of Jan 2024.
