Beta 6.0b1: MSC progress bar present but no active progress during OS .app copy
poundbangbash opened this issue · comments
In testing the stage_os_install option and I noticed when the OS Install.app is being copied to /Applications from the DMG there is a progress bar shown in MSC, but there is no progress being shown in the bar. Activity monitor is showing 100s of MB/s being copied, but no indication in MSC of how long that should take. After the copy finished the progress bar showed progress during the next phase of the task.
This is not easily addressable. ditto only gives us file-by-file progress info (not bytes/kbytes copied). The majority of the copy time is copying one single large file -- the SharedSupport.dmg. (thus: little progress for a long time, then suddenly it's done)
Ideally, you make the item as unattended_install = True and the copy to /Applications happens in the background and the users don't have to worried about it.
BTW, this is the exact code that runs when Munki copies any items from a disk image. For years there was no real progress reporting at all -- just an indeterminate progress bar. The current implementation is still widely inaccurate, but the best we can do with the tools we have.
Closing as there's really nothing we can do about this.
