Mojave (via OC) on a MBP 2020 >

[Geitekaas]

Hello dear people,

my wife’s MBP seems to be reaching the point of replacement. It’s a 2011 version.
I would like to buy a 2020 or later (no M processor) but still want to use Mojave for several reasons.

So I thought to use Open Core (I did my MP 4.1 upgrade and then some 6 other MP’s from friends) and then install Mojave on either a portion of the HD or on a mini stick. Same for Windows 11.

Is this possible? It comes with Catalina, right? So can I wipe Catalina away? Or do I keep a small partition?

So to be clear: OC on a MBP using either partitions or USB-sticks and use Mojave, an os lower than originally installed (Catalina) and Windows (I have a full licensed version)
I do hope so but I will anxiously be waiting for an answer!

thank you all.

Unfortunately, Mojave will not work on any 2020 MacBook Pro, because it didn't ship with Mojave. To get it, you'll have to get a Mac that shipped with Mojave, or that is otherwise compatible (i.e. an older Mac that shipped with something OLDER than Mojave).

Even with Open Core? I can install any OS on my MP.

Macs are flakey with these things, you need to be sure that your hardware will have drivers because unless the hardware existed during Mojave's lifetime it will not. So that means you may have working Wifi but no sound and GPU acceleration, or sound but no Wifi. You can install it I'm sure, perhaps using an older Mac to complete the install, but it likely will not be 100% functional unfortunately.

Darn. But thank you. I hadn’t looked at it that way. I suppose that a 2020 MBP has newer hardware than a 2019. Indeed it has. And takes more memory.
But I really wanted Mojave. I’ll wait in hope that someone here has a 2020 and tried it out. Otherwise it’s to much risk. Thanks again.

Is there any reason you wouldn't consider a 2019 MBP instead? I don't remember too much about what changed between those years. Definitely I understand the desire for Mojave, it's a great OS and I lament the lack of 32-bit app support on newer versions for Intel Macs.

Aside from the 16", which will not run Mojave, all of the other 2019 MBP models have the faulty butterfly keyboard.

Interesting, I thought that the 2019 revision of the butterfly keys had mostly eliminated the issues, but I suppose that's why they abandoned them wholesale in the end.

It’s true. And besides that, the possibility of having 32 Gb of ram. The max in a 2019 is 16. And you can’t upgrade so I’ll have to be lucky with a refurbished one anyway. The graphics card should be a bit better also. I don’t care about the processor.
She uses it for writing and translating jobs. I use it for Photography (Lightroom) and some old 32 bit game once in a while😎. It’s for when we are on the road.
I also thought, I could be wrong, that that changing F keys row is better?
Well, in any case, some major advantages for the 2020, except for the fact that I want Mojave.

In any case, Opencore won't help with trying to get Mojave to run on the 2020.

You can run Mojave on a 2019/2020, but the only way is contained in a VM, via Parallels (VMware might work as well but I haven’t tried that). But this means you are using the resources to run 2 OS’S at the same time. …though there’s so much horsepower in those machines (provided you fix the thermal throttling prob with the cooling mod) that both do run just fine for those 32bit tasks that only Mojave performs. I thought I’d use it all the time, but aside from syncing iTunes to a trillion iPods that Apple forgot still exist, and QT7s nondestructive editing, + a few pricey & excellent apps that never made it to 64bit era, I only occasionally boot into it on the newer machine. Instead I just grabbed a period-correct 2015 MBP to run Mojave natively for a few hundred clams, dropped a 4tb ssd in & just use that for all the extended OS X functionality that new macs can’t do.

It should be noted, if you do want to try the VM route, Parallels is a famously terrible company as far as the business side & pricing goes. They pulled a bait and switch by selling everyone a full featured 2019 version, and then later issued an update that restricted our RAM to 8GB and told everyone to buy a separate pricey subscription version if we wanted to utilize more memory. That was the last time I paid them a dime, as they obliterated any ethical arguments about the acquisition & use of those previous, unsupported versions of software by any means. Or you could probably just try VMWare.
