Virtualbox 6.1 Mac Host & Windows 10 Guest USB Passthrough Problem

I’ve used Windows hosts on a Mac in virtual box for years, but the other day I had to set one up quickly on a spare machine to make an installer USB for a Windows 10 PC. I won’t go into the VM setup process, as that’s pretty well documented, but the USB problems I had were much harder to track down.


Install the Extension Pack on the host (Not guest additions in the guest, although you should do that anyway)

USB Passthrough

It’s common for a VM guest to need access to one of the host USB devices. In this case a USB stick.

I had everything setup as normal, used a filter to select the USB stick I wanted to pass into the VM, the Windows VM could see the USB appear in Device Manager but it had a dreaded “unable to start device” ??


For some bizarre reason, the default virtual USB hub is just USB 1.1. After installing the extension pack, I could select USB 2.0 or 3.0 and voila, the USB stick mounted as normal (and I could proceed to create the install USB).

I’m not sure if I already have this installed in my usual VMs and that’s why I’ve never had the problem, or if something is different about this setup, but it totally fixed my problem.

Data Recovery in Portsmouth

If you search for Data Recovery in my city of Portsmouth, you’ll be forgiven for thinking there are a whole bunch of companies based here, all competing to recover your files.

Portsmouth Data Recovery Search Results

In reality, there is an ad for a national mail-order service based in Wales, and a local IT Support / PC repair shop, all competing for the relatively niche business of data recovery.

I’m not saying there’s anything wrong with those other services, but they might not be what you’d expect. For example, none of the testimonials on datarecoveryportsmouth are recent, or even for data recovery. They seem to be reviews of an IT Support company. (a laptop battery and Smart TV are nothing to do with data recovery!)

Data Recovery Portsmouth Reviews

These type of results are not unique to data recovery services. If you ever search for any local service, chances are the one you want could be way down near the bottom of the results.

In the interest of transparency, I work at one of these companies, but that’s why I noticed these odd search results.

If you need data recovery in Portsmouth, consider DataQuest. We’re actually based in Portsmouth, and we’ve been recovering data since 1998. It’s our core service, we have great success rates, and all of our reviews are for data recovery!

Skylake 2016 Hackintosh

I’ve been waiting what feels like forever for Skylake systems to make the tonymac buyers guide. They finally seemed pretty stable, especially as more genuine Macs made the update to Skylake. I wanted a kind of middle-of-the-road setup to replace a 2006 white iMac I’ve been using from new. Being stuck on 10.7 was starting to cause me trouble, and the 3GB maximum RAM was a nightmare!

I bought most of the parts from the buyer’s guide links. The case I liked was temporarily out of stock here in the UK, so I tried the CIT Barricade instead. It’s a decent small tower, maybe even smaller than it looks online.


I’m happy to report that the system is now updated to macOS Sierra 10.12.2 & running well with sleep, audio, Wifi & ethernet all working. I’ve noticed a minor hassle that headphone sensing won’t work after a reboot, but I’ve not bothered tracking that down yet but it looks like CodecCommander should sort that out. There were a few snags along the way, which were unexpected after my last successful build. My previous hackintosh was a GA-Z77N-WIFI based system running Mavericks and needed very little modification to reach 100% functionality.

Sleep / Wake & System Definition

Sleep / wake is still causing problems when using the integrated Intel HD530 GPU, so I bought the cheapest NVIDIA GPU on the list. I’m usually happy enough with the built-in GPU, so don’t need anything fancy. Sleep / wake is much more important as this is a home system that won’t just be used by me. This was the first cause of trouble for me. After changing the system definition from default iMac14,2 to iMac17,1 for native Skylake power management & chipset support, I lost output to my screen. I used the USB installer to reboot and change the system definition back while I searched for a solution. The root cause seems to be something to do with the hacky way Apple runs Retina iMacs that disables output from the second GPU if two are installed. Fortunately there is a patch that prevents this behaviour, however-patching is needed after software updates. I’ve yet to try an alternative patch that looks like it may install into the Clover config and therefore survive updates.

CPU / Cooler

With the GPU problem solved I was able to switch to iMac 17,1 and get native Skylake CPU power management etc. This sorted sleep / wake, and also got the CPU power management running correctly, as noted by the fan getting loads quieter. A quick note about the cooler (fan) options for these new CPUs. They are pretty limited at the moment, especially in my space-limited case. Despite the awful reviews for noise, I decided to try the stock cooler that came with the CPU. It is every bit as bad as everyone says it is. I’ve not even checked the temperatures as the noise from it is already unbearable. I’m just about to replace it with a Gelid Siberian cooler instead. 

Gelid cooler is now installed & way quieter than the stock intel fan. It uses push-pin installation so there was no need to remove the motherboard. This improvement has now made the hackintosh quieter than the old iMac it has replaced.


Next problem was ALC892 audio. Both ALC892 & 100 series audio need to be checked in Multibeast for working audio. Not a big deal, but easy to overlook. Still yet to resolve headphone sensing after sleep, see note above.


Although my front panel USB ports worked from the start, I didn’t think to check the ones on the back. I realised the block of 4 USB 3.0 ports didn’t work. I checked “raise max port limit” and “USBInjectAll.kext” in Multibeast. This fixed the rear USB ports, but caused a new problem. A few seconds after sleeping, the machine would wake itself back up again. Also instead of shutting down, the machine would reboot. Removing the USBInjectAll.kext fixed this problem. I guess I only needed the Raise max port option.


Ethernet problems next. During the initial Multibeast setup I chose the IntelMausiEthernet 2.2.0 driver as suggested in the forum. The ethernet board showed up in system profile, but I wasn’t within range of a wired connection. When I later went to use ethernet for the first time, the port would cycle between cable unplugged and replugged. Removing 2.2.0 and replacing it with IntelMausiEthernet 2.1.0 got things working normally.

WiFi / Airport

Keen for not just solid WiFi, but also Handoff, Continuity & Airdrop, I read that the best way forward is a genuine Apple Airport card +PCIe adapter. Fortunately some sellers on Amazon have combined these into a single package, complete with external antennas. This was a simple as the physical installation. The card showed up as a native Airport card without any need for configuration or anything. The Bluetooth chip needs a USB connection, and a clever cable was provided to run this from the spare front-panel USB header on the motherboard.


Had I known about all of these niggles, I would have probably still built the system anyway. I’m putting this guide out, so anyone using similar kit can jump right in, without too much head scratching.

Below are the parts I used. I’ve not linked them as I strongly suggest you instead use the tonymac buyers guide (link at the top) for current recommendations, and also to use his amazon referral links which support his site & continued work getting this stuff together.

Ikea ÄPPLARÖ 3 Seater Garden Sofa Hack

My girlfriend and I spent some time recently looking for some garden furniture. After what felt like months of searching, we eventually found what we wanted in Ikea. Note that they sell this on the website with beige or dark coloured cushions, but we found the nice mid-grey cushion below by going in-store. 

ÄPPLARÖ / HÅLLÖ 3-seat sofa

It’s a modular system that lets you configure the number of seats, add corner sections etc. We chose to just get two corner pieces and a middle piece to create a sofa. With the cushions on it looks great, but there was a thought niggling me when I started putting it together. They only actually make one corner section, which you can spin round and use for both ends. the problem with this can be seen below.

If you don’t see it right away I’m very jealous of you. But the way there are two seats with slats facing east / west and then one facing north / south just really hurts my eyes. Sure you can’t see it with the cushions on, but I’m going to be seeing this a lot with just the bare wood showing. [insert joke about the British weather]

Luckily I noticed this problem before I built the last section and realised that by removing 12 screws, I could swap the two sections underneath, and keep the whole thing looking nice & uniform.

I was honestly a little surprised that there was no mention of this anywhere, and maybe most people would just live with it the way it came. But if you’re like me and need things to be just right luckily there is a simple answer in this case.

Just swap over the two pieces of wood circled below. Make sure you get them facing out the correct way to allow the arm / backrest to screw in correctly.

Suppose I’d better add that you do all this stuff at your own risk etc, and this probably will void any warranty you might have. Basically it’s not my fault if you balls it up!

A New Header For My Data Recovery Website

As usual, when I was writing some new content for my work website, I thought I’d also add a bit of colour with a new header. It gives me a break from writing, and also helps quickly show the relevance of a page. Some of my favourite headers are actually quite obscure, so I’ve been replacing them with something a bit clearer.

For example, I wrote a blog post about migrating data to a Mac from a backup, and made a header with migrating geese. It’s a bit obscure, but migrating geese are something local to us here in Portsmouth, and also they add some interest to an otherwise text-heavy site.

So when I updated the Portsmouth Data Recovery page, I wanted to make sure it also had a header that would do it justice, without being too obscure. I went for a night skyline, with a few local landmarks, and a prominent star & crescent design.

I’m really happy with the way it turned out, and it’s given me the motivation to make a few more for other pages.

The other notable thing about these header images is they are SVG (Scalable Vector Graphics) files. They look great on modern high-resolution screens like the 5K iMac, iPhones, iPads, and any other decent screen. They also work at any size without looking rough or blurry, so I don’t need to serve different images to mobile & desktop browsers.

I’ll leave you with another of my favourites…

The Problem is Not Ad-Block it’s Ads

I’ve seen a fair bit of discussion again recently against ad blockers. Even some new services to help advertisers avoid the blocks.

Scale: Intrusiveness of Ads
Scale: Intrusiveness of Ads

It may surprise tech nerds that people outside our field have no idea that ads help fund the free content we consume online. The vast majority of Facebook and YouTube users never stop to consider who pays the hosting fees for those heaps of family photos and cat videos. To these users, ads are just another unpredictable barrier to their stuff. This is especially true when ads are the pop-up, pop-under or pop-between-paragraph type of affair. They disrupt your session and demand your attention. I understand the need for ads to get seen but it’s a bad experience. It doesn’t take a huge leap from there to understand why ad-blockers are so appealing. They easily remove these annoyances at source. Pages load fast, text stops jumping up and down the page, the web works like it did in the good ole’ days. That advert for a new car you were researching stops following you around the web. It’s a massive win for users.

But here’s the thing. Small indie publishers are way down on the annoying ads scale. It’s predominantly large news sites, or blog networks that have the worst of these ads. Squeezing every last penny from their page-views, they poison the web for everyone.

Compare this ad on

Marco Ad

With the ads on engadget:

Engadget Ads

The discreet and relevant advertising on Marco’s site doesn’t alienate users & offends nobody. The Deck has taken this approach, and nobody would ever bother to block deck ads. Why would they? They are relevant to the sites they appear on, and don’t interrupt the experience for anyone. I assume they have a lower CTR than other ad-networks, but they respect the readers and don’t dance all over the page for attention. I expect the quality of leads from these ads is far better than AdSense for example.

Here’s the problem. Ad-block doesn’t just get rid of the awful flash ads that clutter news sites but also blocks unobtrusive ads like the deck. See the example below of the Marco & engadget pages below when using adblock. The engadget page is much improved showing the articles you came for right at the top! On the other hand, Marco’s site is hardly changed at all.

Engadget No Ads

Marco No Ad

Users will happily run ad-block and get their internets back, but the small sites lose out. They never hosted up video ads for cars or holidays, but they lose their small revenue stream thanks to the ham-fisted & heavy handed big networks. You can’t put the blame on users here. They have a tough enough time navigating the evils of the web. Blocking ads just reduces their hassle a little bit.

Update 22-6-2015

On Friday after I posted this article I later saw that John Gruber had basically said the same thing as me in one succinct paragraph. Smart guy.

Better Business Cards

When I ran out of business cards recently, I didn’t just want to get more cold white cards printed. I wanted something that I’d actually want to give out to people. Something a bit fun, but still useful.

Better Business Cards
Better Business Cards

After hearing about through photographer friends, I decided to give them a try. After using a bunch of other printers in the past I immediately liked how simple their online system was. But it was a killer feature that made me choose them for this project. They call it printfinity, and it allows you to choose as many different designs for the reverse of your card as you like. This is great for artists to show off their designs, like a small pocket portfolio, but how could it be useful for me? I work in data recovery so a bunch of photos of hard drives would hardly be appealing.

After trying a few ideas, I came up with the idea of making a range of battle cards. On one side is contact details like a normal business card, but on the other side is one of ten different battle cards. Each card has a simple hard drive graphic and then a series of stats that can be used to battle with. The hard drives are chosen to be vague representations of infamous hard drives, so true geeks may be able to identify some of them.

So now, when we send out a package we slip in a battle card. If it hangs around on a faraway desk for a while instead of getting chucked straight in a drawer, then maybe it’s a good idea. At least, that’s the plan.

Old Vintage Eddie Merckx Racer Bottom Bracket Replacement

Eddie Merckx Racer
Eddie Merckx Racer

There’s not much info about these old bikes, so I thought this was worth a quick post.

The bike in question is an Eddie Merckx “Tour De France. ” Not sure how old, but it has friction shifters, 10 gears and is made of solid old steel.

After suffering with a wobbly bottom bracket (ooh er…), my mate John decided to replace the BB and solve the problem for good. We had heard that you can swap out the old bearings and races with a modern sealed unit and enjoy years of maintenance free cycling.

After a bit of searching, we found a Shimano BB with 68mm diameter, 127mm spindle length that we thought could do the job. It worked a treat, but there were a few things worth noting.

  • One side is reverse threaded so you turn it clockwise to undo it.
  • Be really careful with the threads as they could easily be trashed if you don’t line things up and screw carefully.
  • You will probably need a Shimano tool to tighten the new BB into place. It looks like a normal socket, but with deep ridges on the outside.
  • You may also need a “hub puller” tool to get the pedals off the spindles.

I will follow up soon with some photos of the hub puller and Shimano tool. Also maybe some links and model numbers. 🙂

Twenty Fourteen Single Post Page Secondary Menu Disappears

After ironing out some issues with my Twenty Fourteen Child Theme, I found another one. This one is not really a bug, as it is quite deliberate, but it was still a problem for my needs. When viewing a single post page, the secondary menu in the left sidebar is not visible. The menu is visible on other pages, and on the overall blog page. Again, I’m not sure why this was chosen behaviour, but there is a float left and negative margin that pushes the menu off the edge of the screen.

On line 3596 I changed the following:

#secondary {
 background-color: transparent;
 border: 0;
 clear: none;
 float: left;
 margin: 0 0 0 -100%;
 min-height: 100vh;
 width: 122px;


#secondary {
 background-color: transparent;
 border: 0;
 clear: none;
 min-height: 100vh;
 width: 122px;

So far, this seems to have reinstated the menu, but I’ve yet to test this much yet. There is a chance it may cause trouble under certain conditions. I will see if it causes issues on a full-width page, and check the other media queries for knock-on issues.

Twentyfourteen Sidebar Bug

After updating to WordPress 3.8 I was keen to give the new Twenty Fourteen theme a try. I’ve been using a modified twenty eleven theme forever so thought a change would do me good! Within an hour I had changed the default green accent colour to match our company blue, made sure our contact-form plugins still worked, and got everything looking perfect on my testing site. My pointer hovered over the Publish button, but I decided to give it a quick check on the iPad. Just in case.

It looked great. The responsive layout was beautifully readable, and everything looked fresh and new. There was a slight, but game-stopping problem though.

The Content Sidebar Became Unclickable!

Some of the media queries that control the responsive layout had clashed and caused widgets within the content-sidebar to become unclickable at certain viewport sizes. In my case this was the contact form we have on every page, so losing the ability to fill the form is pretty bad news! I checked on the desktop version of Safari and found the same problem if I reduced the window to approximate iPad size. I couldn’t replicate the problem in Firefox at all.

For reference I was able to find the culprit. Two lines of CSS.

On line 3186 I changed width:100%; to width:66.66666666%;

On line 3192 I changed margin-right: 33.33333333%; to width:100%;

This fixed the unclickable problem, but caused a bit of overlap elsewhere with another media query so:

On line 3578 I changed:

margin-left: -29.04761904%;
width: 29.04761904%;


margin-left: -25%;
width: 25%;

Remember that changing the live-version of the theme is a bad idea, as the changes can get overwritten by theme updates. I changed it in my child-theme instead.

I’m pretty sure this breaks a bunch of conventions that were used in the development of the theme (I hated changing the specific -29.04761904% to a generic -25%) , but it works for now, and that’s what matters. I couldn’t find the correct place to post theme-related bugs to WordPress, so have posted it here for posterity. I will probably have a look at fixing this more cleanly soon, as I suspect there is a quicker fix that I’m not seeing. Especially as this doesn’t seem a problem on Firefox. z-index maybe?
