Installing Macos Catalina From Usb
Installing Macos Catalina On External Drive
I’m trying to install Catalina on an empty external 500gb SSD, formatted APFS. My Mac is also running Catalina. I went to the App Store and fetched a copy of the installer, which is now sitting in my Applications folder, all 8gb of it.
I start the installer, point it at my external SSD, and it starts chugging, looking all OK. The progress meter says 5 minutes. After around that time, with nothing unusual reported, the screen goes black and the restart sequence begins. But it restarts from my internal disk and the new installation is not complete.
Second attempt, I followed instructions to create a bootable USB installation disk on another USB drive, booted to it and started the installation from there. Same result.
Any suggestions?

Installing Macos Catalina On Virtualbox
Here’s how you can create it. Make sure the USB drive is at least 8GB in size, and nothing else is stored on it. Download the macOS Catalina installation file using this link. Turn off the Mac and then insert the bootable USB drive. Now turn the Mac back on while holding the Option key. It will take you to the boot menu where you can select. Target macOS release: Catalina 10.15.x Updates in the installation package - Opencore updated to the latest version 0.6.5. All the kext updated to their latest versions except voodooi2c which does not work correctly for me. Fixed numerous warnings and errors in config.plist - Fixed minor performance and CPU power usage bugs.
