Rest of Mojave install app impossible to be removed from Trash - several attempt with no result
iMac late 2014 running BigSur.
My ssd is formatted as "container" one drive runs BigSur and the other runs Mojave.
All the information which follows are related the drive with BigSur, not the drive "partition" with Mojave.
I tried to run Mojave into Parallels under BigSur in order to remove the Mojave partition and later replace my old iMAC with a new M1 machine and still being able to have Mojave on it under Parallels.
Installed Parallels in the BigSur drive partition and downloaded Mojave. Mojave started under Parallel. Days later I found Installa OSX Mojave.app (italian version) in the Trash impossible to be emptied. Tried in several ways to remove it from the simplest to the more difficoult. Terminal sudo... etc.. Restart with Recovery and made SOS on the drive. Removed completely Mojave and Parallels. No result. I can move back Installa OSX Mojave.app to Desktop and the Trash is empty. Direkt delete of the file is not permitted. Is I try the track to move the file to an external drive I can only copy it because the original remains on the internal ssd of my Mac in its original position. I fell the install app may be damaged because it is only 5,4 GB. Opened the Installa OSX Mojave.app package and deleted part of it. Now the trash contains only Folder SharedSupport which contains InstallESD.dmg with is impossible to remove from trash.
The OS BigSur runs well in my iMac but I do not like to have something in the Trash which I am not able to remove.
Will a new BigSur install be the final solution ?
Thanks for any suggestion
