Hello everyone. I own an older iMac 8,1 desktop. I am trying to install Catalina but running into problems. I am using dosdude1 patcher. Each time I reboot my system (after creating the bootable usb) I hold down the option key and boot from the usb which contains the OS X. It will run but stops halfway and a circle with a line through it comes up. I have to hard boot the system to return to El Capitan. I can't seem to get this to work. I have downloaded the OS X from the link in the patcher. Can someone tell me what I am doing wrong? I wanted to include my system setup info. I am running 8g of ram and a non ssd hd. I can boot into recovery and normal boot but not the efi boot.
