I’ve been getting this error trying to build an installer all day. (See photo attached). I’ve tried this on every SATA disk and USB drive I have. This particular installer came from Mr. Macintosh InstallerAssistant.pkg archive, and I downloaded it over Ethernet directly from the router so I am quite certain it’s not corrupted from the download process. I had only slightly more luck from a wifi downloaded Installer that actually completed the process of making an installer and then failed with a “corrupt installer, please download again” type error in the installation process. Please note, I intend to do a clean install not an update from Catalina (hence why I’m running High Sierra at the moment. Any ideas? [link] [comments] |
