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 supported when running within a VM. Use your native OS X installation instead.

4. UniBeast will only write to an external drive with a partition of 32 GB or less. Larger drives will need to be partitioned.

5. Disable any antivirus software as it can interfere with UniBeast operation.

6. You must disable SIP when running UniBeast on a host running Catalina. Failure to do so will result in a failure to install Clover on the destination drive.

7. UniBeast does not support running from or copying to Case-sensitive file systems.

8. Installation of Clover will always fail if booted in Safe Mode.

9. Failure to write errors are either a bad destination drive or host system USB issues. macOS Catalina requires a 16GB or larger USB drive. macOS Mojave requires a 8GB or larger USB drive.

10. It typically takes between 15-30 minutes to complete copying and creating the USB. The time is all based on system and USB type and speed.

11. UniBeast will detect and only work with a valid purchased copy of macOS install application in /Applications.

12. UniBeast will erase the destination disk as part of the creation process. Make sure you have backed up any files on the destination before running.

13. If you choose UEFI Boot Mode install, the USB stick MUST be formatted as GPT.

14. If you choose Legacy Boot Mode install, the USB stick can be formatted as MBR or GPT. If it's MBR then Clover will be installed to the root of the destination drive. If it's GPT, Clover will be installed on the EFI partition.

15. UniBeast will log to ~/Library/Logs/UniBeast.log which is accessible via the Console application. Any failures or errors will be logged during the appropriate phase.

16. Clover installation logs are written to /var/log/install.log which is accessible via the Console application. Any Clover installation failure logs are written there.

17. UniBeast is a signed installer. Make sure "System Preferences - > Security & Privacy -> General -> Allow applications downloaded from" is checked for "Mac App Store and identified developers" or "Anywhere"

18. If your "Install macOS" is less then 5 GB, then it's the partial installer and will not work with UniBeast. See for a solution.

19. Most UniBeast failures are due to it not finding your valid purchased copy of "Install macOS (version).app" in /Applications, or the application is incomplete or corrupted.

Your copy of the install application can get corrupted if you copy it off to another folder and/or volume. It could also get corrupted if you have multiple copies of the application and then update it from the Mac App Store. When you update the application the Mac App Store download function is smart and can detect if the original is no longer in /Applications and update it in the new location or it will only update part of it in the new location and create the rest in /Applications, thus creating a spilt update.

To fix this issue you need to delete all copies of "Install macOS (version).app" from all mounted volumes and empty the Trash. Then download it again to ensure that you are downloading a clean complete copy from the Mac App Store.

20. If none of these solve your problem then follow the instructions in
