Downgrade mac os mojave how to#

Any comment on this part of the task? Is there something better?Дў.

It is somewhat like RehabMan's procedure for High Sierra, but I'm not sure it will work.

Downgrade mac os mojave how to#

I have a web page that describes how to install Mojave 10.14.4 and change the 'ConvertToAPFS' in 'macOS install data' from True to False to use HFS+, but the procedure is for an actual Mac. But I realize this 'project' may not work, and I have questions.ДЎ. This flash drive, with an EFI folder copied from my Big Sur computer (OpenCore 0.7.5), does boot Big Sur with no problems. For starters I have created a Mojave installer USB flash drive, using the 'createinstallmedia' method shown for Big Sur with appropriate file name changes.

I would also like to use HFS+ on that installation instead of the 'standard' APFS. Thanks for reading sorry if this is boring.ДЇor several reasons, I would like to downgrade MacOS on my computer at left from Big Sur 11.6.1 to Mojave 10.14.x. If I have to do that, I would probably have to change my SMBIOS from iMac19,1 to iMac18,3, as on my other computers. If I cannot use HFS+ on Mojave, I will try the same thing with High Sierra instead of Mojave, and use RehabMan's method of installing the HFS+ file system, which I know works (I have two computers using HFS+ on High Sierra). In general, is there any chance of this working? I'm pretty sure I can do this by using a standard installation (APFS) but don't want that. That sounds right for what I want, but can version 10.14.6 still run HFS+? ДЈ. My 'Install macOS Mojave.app' is version 14.6.06. The earliest MacOS that is supposed to work with an iMac19,1 is 10.14.6. Any comment on this part of the task? Is there something better? Дў.
