When your Mac is ineligible to download Catalina
If your Intel Mac is from approximately 2011 or older (see post #2) you won't be able to download Catalina from the Mac App Store. Follow the instructions in this video to enable the download of Catalina directly from Apple on your older Intel Core 2 Duo or 1st/2nd gen. Core i based Mac. This can also be used on newer Macs if you are having trouble with the download via the Mac App Store. Also note that Mojave and High Sierra are available for download using this method.
Watch the complete video from beginning to end. After the download of Catalina you'll need to build the installer app and then move it to your Applications folder. Required for the use of Unibeast for Catalina later on in the process.
Step by Step:
- Download the gibMacOS Master folder
- Right click and open gibMacOS.command
- Let all the files download (may take 20 minutes or more)
- Right click and open BuildMacOSinstallapp.command
- Drag & Drop the InstallESDDmg.pkg file into the Terminal Window
- Press enter and let the build happen. Takes a minute
- Move Install macOS Catalina App (8.23 GB) into your Applications folder
- Run Unibeast for Catalina to make your installer
Before posting an issue or question with UniBeast please read the following: 1. UniBeast does NOT install anything on your hard drive, it CREATES a bootable USB stick. 2. UniBeast only works on English language systems and is not supported using any other language. 3. UniBeast is not...

Note: You can also use this method on your CustoMac to download and create the complete macOS install app. This is helpful when you try to download the full installer from the MAS and only get the small 19MB "stub" installer.
Your older Mac or Hackintosh must have at least an Intel Core 2 Duo processor and be able to run OS X Snow Leopard or a newer version of OS X to use Unibeast for Catalina or other versions of macOS. Lion for example, requires a 64 bit Intel processor to install that edition of Mac OS X. You should also download the newest Chrome or Firefox browser version that works on your older Mac. Old Safari versions won't pass the security requirements for most sites.
When you create your USB installer on an older Mac expect it to take anywhere from 30 to 60 minutes. Using USB 2.0 ports and mechanical drives can really slow down the creation process.
If you would like to buy, borrow or rent a used Mac mini to create your installer, the 2010 models are the best choice. They all have a Core 2 Duo CPU and at least 2GB of ram which is required for Lion through the Mojave version of macOS.
If you have a 2010 Mac mini or iMac still on Snow Leopard you can upgrade it to Yosemite for free. http://updates-http.cdn-apple.com/2...3ab5-4c92-bfe2-b725447a070d/InstallMacOSX.dmg
MacBook Pros from late 2008/09 or newer will also work well. You can upgrade them to El Capitan for free if you have one that is still on Snow Leopard. http://updates-http.cdn-apple.com/2...cf50-4516-9011-228c78eda3d2/InstallMacOSX.dmg
