Firewall Throughput |
This
is raw throughput, the measurement of traffic flowing through the firewall
without necessarily being subjected to antivirus scans, content filtering,
intrusion prevention, data loss checks and similar steps. The figure can also
vary by protocol and packet size. Some vendors may cite 1500 Byte TCP whilst
others 64 Byte UDP |

Remark |
When compare between different vendor on performance, it need to confirm they are using the same assumption to provide the figure (e.g. Vendor A will enable all features when testing throughput but Vendor B will disable all features) |

MacOS VM on Virtualbox on Lububutu – Upgrade MacOS
A few notes from another users and forum:
1. Updates – this image is 10.13 and the latest is 10.13.6, but the update install never finishes after a reboot and it just tries to install the update, reboots, etc. Here is the fix:
1.a Install the update but shutdown instead of reboot. It will update a few things and then shut down, turning the VM off.
1.b Start the VM again, but as soon as the screen turns black, start to hammer the F12 key. Make sure your keyboard is grabbed by the VM. If you managed to hit F12 at the right time, the VirtualBox EFI should pop up. If the VM starts up normally, go back to step 3.a (yes, you have to download and reinstall the update again)
1.c Now use your arrow keys to select “Boot Manager” and hit Return, then launch the “EFI Internal Shell” from there.
Inside the shell, type the following commands:
Shell> fs1:
FS1:\> cd “macOS Install Data”
FS1:\macOS Install Data\> cd “Locked Files”
FS1:\macOS Install Data\Locked Files\> cd “Boot Files”
FS1:\macOS Install Data\Locked Files\Boot Files\> boot.efi
Essentially, Apple moved the update boot.efi and Virtualbox is running the regular boot.efi and the update doesn’t finish.
If you get “Installing High Sierra” and then a progress bar that takes about 50 minutes, you are golden. Anything else and something is messed. I successfully got the latest xCode running on the latest High Sierra in virtualbox.
Until Virtualbox fixes where it looks for the boot.efi, you will have to do this for every update.
If you success upgrade, you will found the OS version become 10.13.6
