*** UPDATED ON 26 NOV 2019 ***

As time goes by and as social sites becomes more and more pervasive in our life, I’ve decided to make fewer posts on my own blogs but keeping them relevant (at least to me).

This new one is about my recent home network improvement:

  • Vodafone Fiber Link (with Vodafone Station Revolution)
  • Firewall replacement from my old glorious Stonesoft hardware+PFSense with a brand new shining Mikrotik RouterBoard RB2011UiAS

I needed to build VPN access from outer space to my own network, mainly using my two preferred tools: iOS device and OS X on my Mac.

It took me a while to find the right combination of configurations, given the constraints of what I was aiming to. Which was this (naturally IP info has been sanitized 😎 ):

The main reason of almost every post on this blog is the same.

Need to do something, dig the Net, take a while to find stuff so I think to make a note on my… virtual hints book 😉

This time the need was to move a Windows 8.1 virtual machine from VMware Fusion for OS X 10.9.4 to VirtualBox on Linux.

The best option is to export and import the VM in OVA (Open Virtual Appliance) format, but there is no GUI option to export in Fusion. It took me a while to understand that Fusion comes with OVF Tool included, as a command line, and located in the default path “/Applications/VMware OVF Tool

A working example of a command line is:

./ovftool --acceptAllEulas /Users/marco/Documents/Virtual\ Machines.localized/Windows\ 8.1\ x64.vmwarevm/Windows\ 8.1\ x64.vmx /Users/marco/Desktop/Win81.ova

The green part of the command above refers to specific names I gave to the VM in Fusion and to the OVA file.

–acceptAllEulas is an option to make the command less interactive.

apple-bananaQuickly sharing with you all what happened to a good friend of mine, hoping that similar cases will find the solution he applied useful.

It’s out of doubt that OS X has much less issues than its “colleague OSes”, and when it does  the issues are often caused by 3rd party apps…

However there are some considerations which should remain valid, like the one saying that a decent operating system should never allow a 3rd party app to block its basic operations.
And I think and hope that Apple will strengthen OS X over time against these odd situations.

Back to my friend running Mavericks 10.9.2, here’s what he wrote on Facebook:
I rebooted my Mac to clear a small problem. Came up fine. Logged in. It did not go to the expected desktop, but to a *second* login screen. That one won’t accept any password I can think of. Cleared NVRAM, booted to diagnostics, booted to recovery and checked all disk permissions and issues. Everything checks out. Still no love.

Time went by, and some hours later a comforting comment appeared on the post…
It’s all fixed. Seems the latest Dropbox was the culprit. Recovery was pretty straightforward, and I’m right back to my desktop, all settings, data, preferences, etc. intact.

1. Boot Mac with Command-Option-P-R to clear NVRAM.

2. Boot Mac with Command-R to enter Recovery mode; run Disk Utility. Repair Permissions/Repair Disk

3. Reboot with D, run hardware diagnostics

4. Reboot with T, connected via Thunderbolt to iMac and make another backup copy of all personal data; and then

5. Reboot with Command-R again and do a Reinstall OS X. (It’s non-destructive.)

One last reboot to clean it all up, login and get back to work. Right where I left off.

I think sharing these bits is useful, do you agree? Please use comments to let me know your opinions and to add precious knowledge and experience to help apples and bananas to stay always on different trees 😉
