![]() To increase the performance of the virtual disk, enable Host I/O Cache on Controller: SATA. For better memory management between the host and guest machine, click the Acceleration tab and tick the Nested Paging feature in the Hardware Virtualization option. Such problems differ from host to computer, so you may need to do some practice and error depending on your PC’s specifications.īy activating the virtualization feature on the virtual computer, you can set up faster and increase system performance. In that case, try turning off the virtualization feature. Suppose you encounter constant errors or loops while setting up the Mac system in VirtualBox. In addition, if you will use virtualization software on the guest machine, enable the Nested VT-x/AMD-V feature. Otherwise, you may encounter a Load_init_program error during installation.

If your host RAM has a capacity of 16 GB, assign a RAM size of 4 GB or 8 GB in the Memory Size window. Obviously, don't click on any suspicious links in the reviews, and have a nice day/night.You should allocate RAM size and virtual processor to the virtual machine according to the hardware performance of your host computer. ![]() I notice a handful of people that come here spamming viruses and porn ads, and I feel like I'm partially responsible for reviews like that. It is version 12.6.06, and 12.6.03 was used to circumvent an error preventing me from creating the file.
