Original Question:
Can someone give me some advice on this current install? I'm using "EFI for Catalina" from @Middleman and I can't seem to finish. The install gets to about 2 minutes left and then restarts.

It seems like you're experiencing some issues with the installation of Catalina using the "EFI for Catalina" method. Here are a few suggestions to troubleshoot the problem:
ReplyDelete1. Verify the integrity of the installation media: Ensure that the macOS Catalina installer or the EFI files you're using are not corrupted. You can try redownloading them or using a different source to eliminate the possibility of a corrupted file.
2. Check compatibility: Make sure that your hardware is compatible with macOS Catalina. Check the system requirements for Catalina and ensure that your Mac meets the necessary specifications.
3. Reset NVRAM: Resetting the NVRAM (non-volatile random-access memory) can sometimes resolve installation issues. To reset the NVRAM, restart your Mac and hold down the Command + Option + P + R keys until you hear the startup sound twice.
4. Try a different installation method: If the "EFI for Catalina" method is not working, you can explore alternative installation methods such as using a macOS Catalina bootable USB created with the official macOS Catalina installer.
5. Check for hardware issues: It's possible that there may be a hardware issue with your Samsung SSD. Try connecting the SSD to a different computer or using a different storage device to see if the problem persists.
6. Seek community support: Reach out to the community or forums where you obtained the "EFI for Catalina" method for installation. Other users may have encountered similar issues and could provide guidance or specific troubleshooting steps.
Remember to backup your important data before attempting any troubleshooting steps to avoid potential data loss. If the issue persists, it may be helpful to consult with a technical expert or seek assistance from Apple Support.
