Thanks for your reply, Grant! The backstory...I'm working through updates to get a 2017 MacBook up to date. The first update, last night, was to move to High Sierra 10.13.6. Once that was completed, I found the macOSUpd10.13.2.pkg in Finder. Thought it was odd since it's not 10.13.6. I plan to update to Big Sur tonight. I'm a novice at this so I'm concerned about deleting anything unless I know it's not needed before I take the next step. Do I understand correctly that when I upgrade to Big Sur, the macOSUpd10.13.2.pkg I see in Finder under Devices will be removed? Thanks for your input!
