How do i remove macOS Install data

Hello mannanfromcherrybrook,

You should not delete this as I really don't know what will happen If you do as it is required, but if you must try using this terminal command I found on https://forums.macrumors.com/threads/cant-be-modified-or-deleted-because-it-is-r equired-by-osx.1196061/

hope this solves your issue,

That won't solve the issue.

The directory appears to be locked down by a process called System Integrity Protection. You can't delete the locked files even if using sudo from the terminal.

I don't have a solution yet, though I think the process will involve rebooting from a recovery disk and disabling SIP.

As to the reason why this may be necessary, there is a bad macOS installer image on my laptop. The Apple beta installer acquired through the App Store is not working, but at every startup or wake-from-sleep, the system is trying to boot from it, resulting in an endless cycle of failed starts.

My workaround is to hold the option key at ever start, and manually select the still-working HD boot. I'd like to remove the bad installer and start over, but can't find a way.

Are you referring to a beta that you were/are running?
