Willing to try another operating system or would like to test new software, VirtualBox is the perfect option to walk with.

While Windows can be installed on both Mac and Windows, in a virtual machine and without, even dual boot. With macOS, it isn’t like that. A macOS can be natively installed on Mac but with a little trick, it’s possible to do on Windows. With that, there are always some problems around. These problems can appear likely as Apple restricts installing macOS on Windows. The more restrictions on installing macOS on non-Apple hardware the more problems. But these aren’t permanent and can be solved with the solutions we’ll discuss.

Differences between CPUs and the differences between what and where the error appears is important. Similar to these, the reasons and solutions are completely different from each other. Some of the problems are hardware acceleration that appears in different forms and sometimes with different names. This error comes up particularly due to another virtualization program particularly Hyper-v installed.
There are also other ones that we’ll dive into the solution such as booting and installating problems, mouse and keyboard problems, low screen resolution, speed and much more. In this post, we’ll take a look at some of the most common and rare ones and how to fix macOS Catalina problems and errors on VirtualBox.

As I said, thanks a lot anyway.

Virtualbox Crashes Mac Catalina Island
- Several things may be modified.
I’m on an AMD CPU and GPU, and ive had to modify several thing. First, when tweaking VirtualMachine via CMD, ive added following line:
VBoxManage modifyvm “name your mac os” –cpu-profile “Intel Core i7-6700K”
Then, i switched the Network Adapter from Intel ProMT100 Dekstop,
and under System>Acceleration i deactived NestedPaging.
Without these Steps, my VM wouldnt boot. I was stuck on several things,
- freezed at “Start xxHibernate” got fixed by the Adapter setting
- freezed at “Start RandomSeed” got fixed by tuning in the –cpu-profile.
- freezed at “End RandomSeed” got fixed by NestedPaging.
