How to run MOSIE on MacOS
MOSIE (Multi Operating System Image Editor)
If you don't already please install Python 3.8 from here - Python 3.8.2
Drag the MOSIE folder from the disk image to your Applications folder then download the MOSIE EXECUTOR (right click Save File As)
If your Mac says you don't have the right privileges to run the MOSIE Executor then you need to run the below command in your terminal…
chmod u+x /path/to/MOSIE Executor.command
The MOSIE Executor will run MOSIE inside the terminal and open up the program.
Some users may run into Mac's Gatekeeper stopping the app from running, if that's the case please run the below command in your terminal…
Open the Terminal app from the /Applications/Utilities/ folder and then enter the following command syntax:
sudo spctl --master-disable
Hit return and authenticate with an admin password
Relaunch System Preferences and go to “Security & Privacy” and the “General” tab
You will now see the “Anywhere” option under ‘Allow apps downloaded from:’ Gatekeeper options
You’ll now be able to open and launch apps from anywhere under macOS Catalina, Mojave, High Sierra, and Sierra.
