10.13
It's not even alpha. I really hope Apple fixes 10.13, because if this thing stands as is, you'd better stick with what you have, whatever that may be. This thing is slower than an OSX client running inside a VM. In fact I thought I was running in a VM and I was scared to press Cmd-Q. RAM hungry, CPU thirsty, GPU molasses. Just playing an HTML5 audio-only stream in Safari hits 50% of the CPU. Yikes.
For the VirtualBox installation, there is a small difference for first time users of either 10.13 or VirtualBox, and that's a new policy from Apple, which requires that even known developers must be given a stamp of approval before they can install a kernel extension for the 1st time. Expect complains...
VirtualBox
There is a cosmetic issue where the "Details|Snapshots" tabs seem as being disabled all the time.
Removing a CD from the icon of a VM "freezes" the whole thing for 3-5 seconds.
I've seen the weirdest bug ever in several VMs with 3D acceleration enabled (Win7, Win10, Ubuntu12.04). You open a VM, wait until it loads. Then you decide to move the window. The frame of the window moves, the VM stays behind!
For example, I started a Win10 VM on the top right, and then I moved the VM window on the bottom left. The black part is the "container" of the VM that I moved (identified in MissionControl as "Windows 10"). The red part is the desktop of the VM (identified in MissionControl as "VirtualBox VM"). That one decided it didn't want to move, it really liked the starting position:
(BTW, on the bottom, in the Dock, the 2nd icon is the CPU and the 3rd icon is the RAM of a barely used system!)
The biggest problem with this bug, is that it throws in disarray the whole OSX window system. If you start a VM and switch to another space before the 3D accel. kicks in, all crazy things happen. Mission Control gets completely out of control.
Anyway, this is not meant to be a big post or a specific one, only a test of whether VirtualBox can install/run on OSX 10.13b. It does.
Allow me to reboot back to normalcy, I don't think I'm going to be booting again in 10.13 for quite some time...
