Hi,
I have an installer package that runs a postinstall script. The script can take a long time to complete, as one thing it does is copy about 10-30 GB of files using the rsync tool.
We noticed on macOS 15 that the installer would fail almost exactly 10 minutes after it started. Looking in the /var/log/install.log, I see a message like this:
2025-07-01 12:54:32-07 Work-M1 package_script_service[21562]: PackageKit: Terminating PKInstallTask(pid:21573). Task has exceeded its 600 seconds of runtime.
This does not happen in my testing on macOS 12 (Monterey)
I have a few questions about this:
A) Is this documented, and which OS introduced this?
B) Is there a way a developer can extend or disable the time limit via a setting in the installer package. Or if not, is there a way end end user can disable it temporarily on their system?
Thanks, Andrew
You are correct that macOS 15 introduced a script timeout, with a default value of 10 minutes. I believe you can override this using BundleInstallScriptTimeout property, as documented in the pkgbuild man page man page.
Having said that, copying tens of gigabytes of data in an installer script is pretty extreme. Can you explain more about why you’re doing that? Is this data embedded in your installer package and you’re just copying it into place? Or are you getting this data from elsewhere?
Share and Enjoy
