How Do I Remove Mojave and Reinstall Mountain Lion?

I can’t use my 32 bit apps. in Mojave, so I want to remove Mojave and install Mountain lion. I can’t find it on my backup so I need a disk or other help.

    First, jumping back from Mojave to Mountain Lion is a huge step. That’s 6 versions back, from 10.14 to 10.8. Back to 2012. If your Mac originally came with Mountain Lion, then you can do a Internet Recovery and re-install Mountain Lion. But I’m sure you’ll lose a lot of functionality and many apps will stop working as they require something newer.

    But if your problem is 32-bit apps, then you should know that Mojave fully supports 32-bit apps. It is Catalina that will drop support for those old apps. With Mojave you just get a warning the first time you run them.

    Also, it probably isn’t a good strategy to hold everything back just to run some old unsupported and abandoned apps. See

    Or you could simply install virtualisation software and install high Sierra and use your 32-bit apps along side Mojave. I used parallels to get around this problem. As a lot of my software (I use for work is not 64bit) This solves the problem for me.
