The from 07-23-2023 03:10 PM to the of ' Fusion 13 / macOS 12 : 'Unable to create the installation medium'' from 11-24-2022 in which the hdiutil command in Terminal is used (i have used this method successfully in the past so i am somewhat familiar w/how to use it): after issuing the sudo command, i received an error message of '/Applications/Install macOS Catalina.app does not appear to be a valid OS installer application.' even though the Install macOS Catalina.app file was just downloaded it from the App Store. macOS Catalina officially runs on all standard configuration Macs that supported Mojave. Wow, so i'm still having difficulty either getting or creating some complete version of the Catalina installer that will enable me to create a 10.15 Catalina VM, i have tried several of the approaches referenced in your reply but still so far am not having much luck & seem to keep running into roadblocks. Is there something that needs to be done differently w/10.15 since the installer.app files for 10.13 & 10.14 are 5-6 GB in size & installer.app files for macOS 11 (Big Sur) through 13 (Ventura) are all in the 11-12+ GB size range, yet 10.15 (Catalina) is the only installer.app file which is only 19.1 MB in size? What accounts for this huge size discrepancy & how is Catalina to be handled differently than the other versions when attempting to create a VM in Fusion 10? I'm having a problem trying to create a macOS 10.15 (Catalina) VM in Fusion Pro 10: if i try to use the drag & drop method, i cannot seem to 'drop' the Catalina installer file 'Install macOS Catalina.app' (only 19.1 MB in size & freshly downloaded from the Mac App store) into the designated space 'Install from disc or image'/'Drag your ISO file here to start installing' in the 'Select the Installation Method' window.Ĭan i use a different method such as 'Create a custom virtual machine'? If so, i need some assistance in setting up the installation as i am not familiar w/this method.Īdditional notes: i have been able to create VMs for macOS 10.13 (High Sierra) & 10.14 (Mojave) using the drag & drop method in Fusion 10 & macOS 10.15 (Catalina) is the only macOS version from 10.13 (High Sierra) thru 13 (Ventura) for which i have not been able to successfully create a VM in Fusion 10.
