Netgear Smart Switch GS716T v3: Firmware update to V6.3.1.39

Trusty old switch still supported with this July update, Release notes and download link.

How to get the Image to the switch? Go to Maintenance > Download > HTTP File Download and select the image file. Click Apply in the lower right corner and wait until the process finished.

Note: I had to shrink the image filename a bit as the switch didn’t like the length.

Then you can choose to reboot from that image next time

Don’t forget to click on Apply in the lower right corner.

The final step is to reboot the switch which activates the new firmware image.

Big Sur – fix for issue with second display

After updating to macOS® Big Sur I had the issue that when attaching the MacBook Pro® to a docking station, the application windows moved to undesired positions.

The fix which helped me is to create a colour profile for the displays.

Go to System Preferences > Display > Colour and add a new colour profile by clicking through the Calibrate… dialogue.

After new profiles were added for all the displays my issues were fixed.

Tested with macOS® Big Sur 11.0 / 11.1

macOS® / MacBook Pro® is a trademark of Apple Inc.

Raid-10 on an Icy Box IB-3740-C31 – 4-bay USB-C case

Just got an Icy Box IB-3740-C31. Packaging was thankfully good as it was not delivered in a brown box around it.

Adding 4 SSD drives was a bit of a fiddling, but once the two screws per drive were attached and the sliders were in the case it was fine.

Starting up, all 4 SSDs were directly detected by my MacBook Pro.

Noise level is not super silent but ok, maybe I switch the fan later on.

Setting up a RAID-10 with Apple Disk Utility

In Disk Utility, go to File > RAID Assistant…

Who would know that once you have 4 drives you can’t just create a RAID5 with the disk utility? The only obvious options are RAID0, RAID1 and JBOD.

But there is a trick here if you want to use the RAID Assistant. Just create a RAID-10 out of 2 RAID-1 combined by a RAID-0.

First, we create a RAID-1 with 2 disks:

For my use case I used the largest block size and named the first RAID-1 raid1_1.

Then I did the same steps again with the second two disks, named it raid1_2.

Now as you have 2 RAID-1s, it makes sense to combine them to a RAID-0 – set the same block size and works fine. Named it raid10 (finally).


  • If you have 4 drives you get 50% of the capacity (e.g. 4x 1TB -> 2TB to use)
  • up to 2 drives can fail here and it would still work (1 on each RAID-1)
  • better fault tolerance than a JBOD
  • fast(mirrored & striped) compared to JBOD, single drives
  • a lot cheaper than a NAS
  • faster than a NAS with up to 10 Gbit/s via USB3.1 (Gen2, UASP)


  • a software raid on top of another software raid, not sure yet if you can move it between macs?
  • RAID-5 would give you 75% of the capacity (e.g. 4x 1TB -> 3TB to use), but only one drive can fail there
  • Only attached to one computer compared to a NAS – but possibly more speed


The Icy Box seems to work fine so far, and it feels quite fast (no scientific test/speed runs here) to copy large files around – it’s definitely a lot faster and responsive than the NAS in the same room. Looking forward to video editing on it.

Would have loved to go with a RAID-5 but for now I can always use the provided system tools.

Lightroom Classic CC 7.3: Here are the Fujifilm Presets

After updating to the current Adobe Photoshop Lightroom version, I did not find the famous Fujifilm presets like Velvia, Classic Chrome etc. anymore. As Adobe changed and extended their own Presets, I was eager to find the Fujifilm ones – and found them.

Let’s quickly look at where they are now in three easy steps.

First, go to the Develop module. On the right pane, open the Basic tab:
Second, you will find the Profile option, default is Adobe Color. Here you click on Adobe Color and a small menu opens:Third, click on the Browse option and then you found it again. Now open the Camera Matching tab and you will find the specific Fujifilm color profiles:

Best regards and have fun with the settings.

Apple Wireless Keyboard

Hups, didn’t know that – my old wireless keyboard is updatable for some years and I missed that? Not really, as it happened already automagically. Here you can check which device you have: How to identify.

My firmware version of the 2011 wireless keyboard is already up-to-date: Firmware Version: 0x0050

Mixing Fujifilm X-T2 with Minolta MC and MD lenses via mount adapter

Fujifilm offers a Leica M mount adapter for the X-Mount cameras including the X-T2. As I am currently not in possession of a M mount lens this might be a bit impractical. However, the idea is quite a good one and a short web search brought me to K&F Concept who offer a vast amount of different adapters to camera systems. I opted for the Minolta MD/MC to Fujifilm X mount adapter to use my available lenses. Benefit of using the Minolta lenses: as the adapters make the lenses only manually usable the Canon lenses without manual aperture ring would not work in a practical way (change setting on Canon camera, move it to Fujifilm camera) and also the benefit of the lightweight system would be absurdly dispensed with.

The test subjects

I have three Minolta lenses, which all fit perfectly on the adapter. Now to a sample picture per lens. Please note that the first sample picture has one of the famous settings by Fujifilm applied, Classic Chrome.

  • Minolta MC ROKKOR-PF 58/1.4
    • excellent bokeh
    • focusing takes some time
    • looking forward to portrait work (87mm equivalent to full frame)

  • Minolta MC W.ROKKOR-SG 28/3.5
    • focus ring easy to use
    • fast to focus
    • not so fast regarding aperture, but sharp and for the sunshine
    • almost a default lens (42mm equivalent to full frame)

  • Minolta MD TELE ROKKOR 200/2.8
    • long focusing time
    • steady hand required
    • quite a tele (300mm equivalent to full frame)

Color Profile: Camera Calibration section in Lr

Adding a Color Profile after shooting with RAW is still possible via Lightroom in Develop mode, Camera Calibration section on the right hand side:

Alternatively you can use the Fujifilm RAW Studio which does the job with the camera processor.


So far I am extremely pleased with the K&F Concept adapter and the Minolta lenses on the Fujifilm X-T2. It is quite some joy to use the old Minolta lenses and the results are very good indeed. Combined with the Fujifilm Color Profiles, this is just wow. The adapter is solid, no wobbling, no nothing and just works as expected. With the Minolta lenses the camera is also not front-heavy, they fit in size quite well (maybe except the 200/2.8). Despite that the 58/1.4 is of course quite a fast one and the 200/2.8 is like a good tele but requires a bit setup time – probably tripod mandatory.

Fujifilm X-T2

Thoughts, then actions. Quite pleased with the Fujifilm X-T2 so far.

Here are my initial comparisons to the old Canon 5D Mark II:


Amazingly easy to use and crisp results – such an advantage. Autofocus is extremely helpful.


Really useful, sufficient for many pictures especially fast street photography.


By far less time to shoot than the Canon. Maybe because there is always a display on (auto-turn off after 2mins selected)? Also the battery has less capacity (1200mAh vs. 1800mAh in the LP-E6).


Initially I thought the lens was not recognized correctly, however the correction profile is already included in the RAW-File – nice:

So I don’t have to manually click on EnableProfile Corrections.

The Tether Shoot Plugin for Fujifilm cameras costs 29$.

Otherwise tethering does not work with Lightroom:

RAW Studio

Tried the new Fujifilm RAW Studio, it has a nice feature: the camera converts RAW to jpg while attached via USB, so computer does not calculate and it’s quite fast. Despite that I saw nothing of interest to me. So if you are planning to mass-convert images, go for it.


I updated the provided firmware to current versions:

Body Version 2.11 to 3.00
Lens (18-55 Kit) Version 3.21 to 3.22
Download from Fujifilm, for the update  just put the files on a formatted SD Card and hold DISP/BACK button while starting the camera.

Reactivate old RasPi

As my first Raspberry Pi catched some dust I found a new project involving it.
Researching current procedures regarding backup old image and add new image to the SD Card, here it is:


  • Putting the SD Card in my reader in my Mac
  • Utilities > Disk Utility
  • File > New Image from boot
  • Choose as type CD/DVD image and save it

New Image

The really cool and minimalistic tool Etcher is suggested by the RasPi homepage.
I chose the current Raspbian 9 to be put on the SD Card by Etcher.

Etcher in use

Once the copy/install process was finished I opened a terminal session, navigated to /Volumes/boot and used touch ssh.

This will enable ssh on the RasPi, directly enabling it to be contacted by a terminal session instead of putting a usb keyboard on it.

  • User: pi
  • Password: raspberry

Any changes can be done with sudo rasps-config – especially password and network name of system

Now the old RasPi can be used again, this time without extra ac plug but on the new Bestek Steckdosenturm.
