Need some answers with Mojave in a VM and Catalina as a slave.

[vemac575]

So I just got my maxed out, 4tb 16" Macbook pro... What a dream, right? NO! I'm living a ****ing nightmare! Catalina is a curse for musicians who use a lot of plugins.

SO, I need to run Mojave through parallels, which I am going to do, but I need some answers before I waste my time.

1. How realistic is it to use most of the resources to run the VM, only using the stock OS as a slave to do so? Example: I primarily use Mojave to produce and compose, with 95% of all RAM, CPU, and even 3.5TB of the 4TB drive, only using the stock OS (Catalina) to host it.

2. Will coherence mode be more reasonable?

3. Considering question number one, will it be fast enough? Will it be just as fast running Mojave in VM as, with the resources allocated, as if it were running without a VM, with those same resources?




Thanks for any and all help. This is such a pain in the ass.

I've never heard of anyone running a DAW successfully through a VM.

Bad problems with Catalina and Logic Pro X on a 16" MBP are documented in this forum…going back to January, I think. I don't know if it applies to any other DAW…since you didn't say which one you're using. Those guys would probably tell you to return the 16" if you still can!

I'm using LPX. Sux. Can you please refer me to these posts with some links?

I can't take it back because I need the 64RAM but I need something portable. I'm screwed I guess.

This is the main one:

Glitchy/Thumping audio in Catalina system audio (Not the video popping Pause/Play issue)

Yes incredibly annoying. Can’t believe they have left this and no fix yet!

I'm in Mojave so I've never seen the issues in person.

You're not going to be able to get audio apps to work successfully in a Mac VM. The performance just isn't there.
Coherence mode won't help with performance either.

There will also be no graphics acceleration inside a VM so macOS will run extremely poorly.

I continue to be surprised how well macOS runs in a VM. I frequently use High Sierra VM using VMware Fusion.
