First off, apologies if I've inadvertently duplicated some information already in another post; I tried searching but couldn't find anything which mentioned this:

If you're going to upgrade Lion to Mountain Lion, make sure you also update the VM guest Settings so that OS X 10.8 is selected under Options -> General.

Until this morning I had a working copy of Lion running inside VMware Workstation 8 on a Windows 7 host. Then I bought Mountain Lion and tried to install it. The installer did something for a few minutes and then tried to reboot the guest. After that point, the guest would no longer boot; it would constantly drop into the EFI shell after a minute or so.

I tried installing VMware 9 (and the 1.1.0 unlocker again), but that wasn't enough. I tried using Lion Disk Maker - http://blog.gete.net...n-diskmaker-us/ - on my real Mac (early-2007 Mini with a C2D upgrade) to create a couple of USB sticks, one with Lion and the other with Mountain Lion. The Lion USB stick would boot inside the VM but then gave a bland "there has been an error installing Lion - please try again" message or words to that effect (I can't remember the exact text), but the Mountain Lion USB stick wouldn't boot inside the VM at all.

Then I had - I think - a brainwave. I powered off the VM guest and went into the VM's settings. On the Options tab, under General, is a control to select the type and version of the guest OS. I changed it from 10.7 to 10.8.

Once I made that change, the VM guest booted successfully into the expected installer. As I write this, it's installing OS X with "About 16 minutes" remaining. Once the installation is finished, I'll see if I've got any further headaches with drivers, kexts and the like before the guest runs stably.

On the face of it, OS X 10.8.1 appears to have installed successfully. Sound is working without any further fiddling (I don't know if that's because I upgraded from Lion with working sound, or whether a fresh install would also be fine) and all my previous settings and applications appear - so far - to have been preserved.

So far, so good...

Hi,
One thing I noticed is that LaunchPad is not working anymore: so slow that it is completely unusable.
Can you confirm you have the same issue?

Also, I'm curious about your audio settings.

Thks,

Sorry for the slow response; I only just saw your reply.

I don't normally use LaunchPad, as it's a gimmick to appease those weaned on touchscreens. However, I've just tried using it and can confirm that it runs abysmally slowly on my setup as well.

As for audio settings, what would you like to know?
