To reinstall your Mac's OS without an installation disc you need to firstly make sure that you keep your Mac turned on during the whole procedure, and that your Mac is connected to the internet.

In this article we will show you how to reinstall Mac OS without disc. If you find any problems with the SMC fix, kindly direct your enquiries/complaints to me zer010gic has kindly integrated our 'fix' into the published ISO on my behalf.MacOS includes a recovery partition that allows you to easily erase all data on your Mac and reinstall your OS without an installation disc. Hope this helps explain the state of things! Let me know if you have any more questions. I haven't had the chance to look into the VMDirectPath I/O issue I've seen the discussion but have not yet had the time to investigate. Using iovDisableIR=TRUE should provide a good workaround until we can properly address that issue too. The boot PSOD is under investigation and will most likely also be addressed in due course. If you are planning on using this in a production environment, you should take whatever steps you feel necessary to satisfy yourself that this engineering fix meets your needs before deployment, and you should understand that VMware support will not necessarily be able to help with issues arising from this specific patch. We'll still need to address the issue fully in an update/patch release in due course, timeframe unknown, but this should keep you going in the meantime. Although the Macmini6,2 isn't on the Hardware Compatibility List, we want it to be usable, so in the absence of any reasonable workaround for the SMC issue, we've produced a very minimal and very unofficial engineering 'fix' to get things working.

That seems to be fixed now: whenever I press the Alt key at the powerup chime, I get the Apple 'boot menu', even with our KVM switch in between. PS2: on the earlies models we had the problem, that the Alt key wasn't recognized after powering on, when there is an USB hub between the keyboard and the Mac (a KVM switch for example). PS1: I was unable to boot the ESXi setup from USB key! Since other USB keys (OsX setup for example) didn't work either, I suspect that there's some EFI boot problem from the new USB3 ports. It is the regular MacMini with an i7 4C 2.3GHz and one 1TB SATA drive ( with no extras), not the MacMini Server. I tried instalkling 5.0 and 5.0 U1 also, but with the same result. I bought one of the new MacMinis, which were presented yesteraday, plugged two 8GiB DD3-1600 modules in (OsX reported 16GiB of memory, as the models before) and tried to install ESXi 5.1 Build 799733.
