How to get installer path from installer plugin
Is it possible to get the installer's path from installer plugin? For example, I have installer on ~/Documents/MyInstaller.pkg. I'd like to get the full path of the file, ie. /Users/MyName/Documents/MyInstaller.pkg (or even to /Users/MyName/Documents). NSString *path = [[NSBundle bundleForClass:[MyPlugin class]] bundlePath]; returns the path of where the plugin is located after it was loaded, which is in a temporary folder. NSURL *appBundleURL = [[NSBundle mainBundle] bundleURL]; returns /System/Library/CoreServices/Installer.app for the Installer.app's path. I tried examining the environment variables available to the plugin using: NSDictionary *env = [[NSProcessInfo processInfo] environment]; however there are nothing about the actual installer path. My goal is to check if there is a certain file exists in the same folder where the installer resides, and read the information from there. The information will be used in the plugin, before installation process starts (so a preflight script would be too late in this case). Any help would be appreciated.

softwareupdate change behavior in Big Sur
I have a daemon that can check for and install software updates using softwareupdate. Up to Catalina 10.15.6, the order is softwareupdate --list for each update { softwareupdate --download softwareupdate --install } if any update has Action == restart restart The above has worked so far, but starting with Big Sur beta 5, I was getting infinite loop of download, install, restart. After some trial & error, it appears that in Big Sur whenever Action is 'restart', the --install has to be paired with --restart. For example, updating from beta 6 to beta 7 would be softwareupdate --install "macOS Big Sur Beta 7-20A5374g" --restart This is not consistent with softwareupdate's man page, which has not been updated since 2012. Anyone else notice this change? I don't know if the pairing --install/--restart is intentional because of the new Update volume, or is a bug that will go away soon. I already files a bug regarding this, FB8700934.
