How do I install Catalina on an old Mac?
To install macOS Catalina on an unsupported Mac, you can use OpenCore Legacy Patcher. Notably, this method is only a trick and isn't supported by Apple. Learn the risks and limits before you try it.

1. Download OpenCore Legacy Patcher from its official website.
2. Prepare a USB drive and erase it to Mac OS Extended (Journaled).
3. Use OpenCore Legacy Patcher to create the macOS Catalina bootable installer (there are on-screen instructions).
4. Use the bootable USB drive to boot the incompatible Mac.
5. When the Mac starts up, click OK on the prompt to install OpenCore Legacy Patcher. Then, you can run macOS Catalina.

How do I download macOS Catalina if I can't get it from the App Store?
If you can't download macOS Catalina from the Mac App Store, your Mac may not be compatible. You can use iBoysoft DiskGeeker for Mac to download the Catalina DMG and create a bootable installer.

Notably, downloading Catalina on an unsupported Mac doesn't make it compatible. iBoysoft DiskGeeker for Mac simply lets you download the DMG for storage or sharing; it doesn't bypass Apple's hardware compatibility requirements.
