I want to run Windows 10x64 Professional as guest on a Mac OS Mojave host. Well, it does run, but the performance is very low and Virtualbox rises to 200% and more CPU usage in Mac OS activity monitor, although the guest is idle. According to the guests windows task manager cpu load is low. I searched the forum and tried various steps from other posts I found here. But first the exact specs of the host machine.
Host:
What I tried/did already:Model Name: MacBook Pro
Model Identifier: MacBookPro14,2
Processor Name: Intel Core i5
Processor Speed: 3,3 GHz
Number of Processors: 1
Total Number of Cores: 2
L2 Cache (per Core): 256 KB
L3 Cache: 4 MB
Memory: 16 GB
OS: Mac OS Mojave (10.14.4)
- enabled 2D/3D acceleration
- made sure that guest does not use up all CPU cores (according to system info I only have 1 processor with 2 cores, so I set Virtualbox to only use 1 core
- made sure that Virtualbox not uses up all RAM, I set it to 3072MB of my 16GB total
- installed the VirtualBox Guest Additions
- installed the VirtualBox Guest Additions Expansion Pack
- set video memory to 256MB
I have attached a logfile which covers the following:
- startup VM
- login into guest OS
- wait for the host CPU usage rises to more than 100%
- shutdown the guest OS
Any help is highly appreciated. I'm new to the virtualization game and don't really understand all the possible settings yet, so I might have made a mistake with one or more of them.
Another issue with the guest is, that I have weird graphical glitches, like windows are not drawn completely, with huge black or white areas where normal windows content should be, but I will make a separate post for this.
Cheers
