i got an error ocsb no suitable signature security violation

ocb load image image failed

That is because Since 0.6.1 is AppleSecureBoot implemented. Add in your config.plist into Misc-Security string key named SecureBootModel with value Disabled.

or use GibMacOS method which is pure vanilla

Niresh Catalina is old for your system so you need to use Gib Mac Os method and make a installation drive using latest catalina version.I reccomond catalina 15.6 or later

I think yow have downloaded image that is for original mac or you did not unzip the compressed file containing the image or try using transmac. If it also doesnt work let me know. I will provide the link from where i downloaded.

Please give me the link as I have already messed up with niresh Catalina and Oralia and it took about 2 hrs to download the image.

I cannot share the link here give me your telegram or instagram   account link.
