Monterey on external SSD

[mvismara]

Hi everybody!

My name is Marco, I'm from Italy and I'm new here.

I have a perfectly working Hackintosh built by myself two years ago running Mojave, and I would like to stick to this stable OSX for the moment.

I would like to know wether is it possible to install another OSX (Monterey?) on an external SSD.

I searched the internet only to find tutorial on how to build an installer but that's not what I'm after, I would like to have an installed parallel OSX to use as an alternative of the main OSX.

I hope I've been clear.
Thank you!
Marco

May work, if your usb ports are setup correctly

best to use internal though

How can I tell whether are the USB ports correctly setup?
They seem to work fine...

Any idea on how to install the OSX on the SDD?

Thank you

Important Update: June 2023 From Big Sur 11.3 on the built-in OpenCore XhciPortLimit quirk no-longer worked as described. This became a known "bug", though in reality it was Apple changing their internal code, making a simple "peek and poke" to keep it operating, a difficult task. However, with...

yes it will work.....
if you can either boot via the main motherboard or the "option" key..

the way to install it is plug the drive into the computer, format & partition it
Then go to the installer & when it asks to select drive, chose the external one.

now...... the trick here is to ensure that you use a USB port that is always on full the whole boot process.
Test using a KB & an external hub+ your device.

I have MacOS Sierra 10.12.6 / MacOS High Sierra 10.13.6 installed on one disk, and MacOS Mojave 10.14.6 / MacOS Catalina 10.15.7 installed on another disk (both internal) and I am able to boot from any of them. So it should be possible to install another MacOS version as an alternative to the main MacOS if you want. I agree that it is best to use internal disks, though.

I have not tried MacOS Big Sur or Monterey, although I have no reason to suspect otherwise. I believe you should be able to use the OpenCore bootloader to "multiboot" between MacOS Mojave and a newer version.

I'm dual booting Big Sur 11.6.5 and Monterey 12.3.1, internally. I could boot Big Sur via USB but it's slower.
