/system/installation/packages/osinstall.mpkg appears to be missing or damaged
Hello!
I bought my Macbook Pro 13’ last Wednesday and everything was fine.
However, today, I turned on my laptop, inserted my password, and the bar went to half the space and entered into the update page (sorry for my bad computational language), and it said “/system/installation/packages/osinstall.mpkg appears to be missing or damaged ” and that I should restart my computer.
After that, I restarted it, it did the same thing and appear the same message “/system/installation/packages/osinstall.mpkg appears to be missing or damaged. Quit the installer to restart your computer and try again”
Thank you for your time.
