I'm running 14.1 on my Late 2014 Mac Mini thanks to OCLP. Everything seems to be working just fine but when I go to update to 14.2.1 the updater says that the package failed validation during the 'preparing package' phase. I'm getting the same type of error when I download the latest installer (also 14.2.1) through OCLP to make a new boot key. Any ideas what could be causing the package to fail the checksum check?
