Update: 2018-OCT-01 – This post applies to VMware Fusion version 8.x and older. Updates were made in VMware Fusion 10 to make it easier to create a UEFI-enabled VM from the GUI.
Let’s say you want to build a new VMware Fusion virtual machine using the newer UEFI firmware instead of the traditional BIOS. How is that done in VMware Fusion? Unlike VMware Workstation and ESXi, there’s no GUI-based option to choose EFI over BIOS (at least as of this writing). So, I decided to put this post together to walk you through the process. I should also point out that this needs to be done before an operating system is installed to the VM.
In this blog post, we’ll take a look at how to setup and install a brand-new virtual machine using VMware Fusion. For this post, I’ll be installing a fresh copy of Microsoft Windows to use as an example, but these same steps should apply to just about any operating system. Let’s get started!

If you’ve been following the news, there was a recent phishing scam going around that was involving a number of Google Docs users. (If you’re not familiar with this story, check out this post by US-CERT). Fortunately, I didn’t receive that phishing attempt message myself.
However, there now seems to be a similar phishing attempt going around, but this time it involves Dropbox. A number of sites have stories on the Google Docs scheme, but as of this writing, I haven’t seen very much involving this particular Dropbox scheme. In the email I received, there were a couple of giveaways that stood out to me:
I wasn’t expecting any sort of shared document from the sender. Even though she’s in my contact list and is someone I do communicate with, it wasn’t something we had previously discussed.
This one is probably the most obvious, but the From: and To: email addresses were the same. Even though I received the email, MY email address wasn’t listed in the To: field.
It was sent to the wrong email address. Although this email address was once associated with Dropbox at one time, it isn’t any more. If this was legit, it would’ve gone to another email address.
If I hovered over (not clicked) the “Secured Document” link, I could clearly see that it wasn’t going to a Dropbox URL.
At this point, it was pretty obvious to me that this was an attempted phishing email, but I even reached out to the “sender” of this email to see if she had sent it. Her response back made it clear that she hadn’t sent this out.
Here’s a screenshot of what the email looks like. Remember to stay vigilant and question emails like this, especially when it’s not something you were expecting to receive!
Now, I know I said this blog was going to focus mostly on virtualization and all, but every once in a while, you stumble across a tech-related issue and a fix or workaround that’s just worth sharing. This, in my opinion, is one of those times.
Occasionally, my Mac would wake itself up from sleep mode every now and again. At first, it didn’t seem like much of an issue, but I recently noticed that it seemed to be recurring at regular intervals, almost on a schedule of sorts. So, I took to the web to see if I could figure out the issue and here’s what I found:
Check the logs using Terminal
Open a new Terminal window (found in /Applications/Utilities) and run one of the following commands (based on your OS version):
For Mac OS 10.12 “Sierra”:
log show | grep -i "wake reason"
For Mac OS 10.11 “El Capitan” or earlier:
syslog | grep -i "wake reason"
I ran the terminal commands on my system, and in the screenshot below, the logs showed that a “Wake from sleep” instance was occurring almost every two hours!
What do these “Wake Reason” codes mean?
Ok, so my system is waking from sleep on a regular basis due to a RTC code, but what does that actually mean? Well, I found a blog post over at www.osxdaily.com that explains the codes in more detail:
OHC: Open Host Controller (usually a USB or Firewire device). If you see OHC1 or OHC2 it is probably an external USB keyboard or mouse that has woken up the machine.
EHC: Enhanced Host Controller is another USB interface, but can also be wireless devices and bluetooth since they are also on the USB bus of a Mac.
USB: a USB device woke the machine up
LID0: this is literally the lid of your MacBook portable, when you open the lid the machine wakes up from sleep
PWRB: Power Button, which is the physical power button on your Mac
RTC: Real Time Clock Alarm, is generally from wake-on-demand services like when you schedule sleep and wake on a Mac via the Energy Saver preference pane. It can also be from a launched setting, user applications, backups, and other scheduled events.
As you can see from my Terminal screenshot, I had a RTC code kicking off every two hours. Because of the RTC codes, I decided to check my settings in the Energy Saver system preferences. I also had a few UHC and EHC codes mixed in there, which was probably me (or someone in my family) clicking the mouse or keyboard to wake the system from sleep.
See if “Wake for network access” is set
Open System Preferences > Energy Saver
Uncheck: Wake for network access
See if a Schedule is set
While still in the System Preferences > Energy Saver window, click Schedule…
Ensure that Startup or wake is unchecked (unless, of course, you actually want your system to startup or sleep at a specific time).
As it turns out, my particular situation was indeed the result of “Wake for network access” being checked in the Energy Saver preference pane. After unchecking this setting, my system is no longer waking from sleep every two hours! Hopefully this post helps you to resolve your Mac’s “Wake from Sleep” woes. As always, thanks for stopping by!
Hello everyone! Earlier today, I was looking for a way to list the RDM disks that are currently attached and in use by VMs within a specific cluster. See, we’re in the process of decommissioning an old SAN array, and I needed to verify that specific LUNs and RDMs were no longer in use. I came across this post over on the VMware Communities portal, but needed made a minor tweak, as I only wanted to search a specific cluster. By the way… HUGE thanks to user LucD for posting the original script! After running this script, I was then able to search the output to ensure that the LUN WWNs I needed to decommission weren’t in the list.
Hello, everyone! I’m launching this new web site as a way to share technology-related information and experiences that others might find useful. My goal is to focus mainly on virtualization, but I hope to include other consumer-level tech content as well. For those of you that know me already, I’ve talked about all these various ideas I’ve had for a while now. Starting this web site is the first step in turning some of these ideas in to action. Let’s see how this goes!
