When I used this version
http://www.mediafire.com/file/oszlggdb22bg0i5/Olarila+Catalina.raw.zip/file
, the system wrote 5 or 6 commands and freeze.
in the previous version of Catalina (10.15.7). it was directly writing a set of commands, and then immediately the installation process would be completed without any problems, so I want the old version.
