Oh yes of course, thanks

Didn’t mean to reply directly. I had a look, several actually, but found no clear answers so attempted to provide levity.

Good to know and @Velocio thanks.

It's not irreversible but get a friend to set the admin password to something you don't know and use that account to set dummy IP addresses for all the interfaces.

@William.
^ this seems the most sensible way to do it. A bad IP address for the gateway should stop it knowing how to get online, and an admin password you don’t know will stop you fixing it.

After leaving my bike outside (under a cover though!) my chain is rusty. I used to buy KMC510hx’s but can’t find any online for quick delivery (or in my Lbs). Has anyone got any other chain recommendations that are similar?

Is there an irreversible and permanent way of removing all internet capabilities from a macbook? It's a 2012 ish white one

Do you still need the macbook to function otherwise? 😁

Seriously though... are you a systems engineer? If yes, then no. If no, then yes.

I can basically break any ability for it to do anything even if you connected it to any network. The macbook would no longer be able to receive any updates or interact even with the local network, but presumably you're good with all of this and are OK using USB sticks to move files on and off it.

The phrase you want to be Googling is "air gap"... and air gapped machines are physically incapable of connecting to any network. In security this is the standard for working with malware and viruses of a certain class to observe them.

Here's the kind of thing we're talking about: https://tech.firstlook.media/air-gapping-part-one

And basically you take your Macbook to a repair shop and ask them to remove the network card and accept the risk of doing so (may kill the machine if the engineer is an idiot).

Afterwards you have a Macbook that can do everything except communicate with anything else.

Oh, and if you're wondering whether air gapping always makes security work easy... nope. Sometimes malware communicates via the microphone and speaker! Or by ambient light sensors. But it pushes the class of malware firmly into state actor territory. Additionally there's always the Stuxnet "let's load a USB file with the virus" method, etc, or "let's infect the BIOS or something low level and then infect USB devices which carry it elsewhere" and so on.

Air gapping isn't perfect from a security perspective. Clean devices, working in clean rooms, and investigating the virus from first principles is the way to go here.

https://www.decathlon.co.uk/p/1-speed-bike-chain/_/R-p-257 is a galvanised KMC chain in a Decathlon box, in stock in many branches. It's holding up well on my RollerFort, where everything else is terminally corroded, so mere rain isn't going to be any challenge.

If anyone fancies a wiki dive, check out TEMPEST hardening, which is the NATO standard for computational equipment to resist penetration. Phreaking is a particularly good example of the ingenuity of people who steal other people’s info for a living, on behalf of a government.

Nice, cheers!

Thanks, good to have this explained. I basically use the machine as an image database for reference, and occasionally typing out poems. I connect to my printer via USB, and obviously have another machine for network access, which I can remove from the studio.

Yeah, don't want to break it completely obvs. But the permanence of this solution sounds good in terms of head space; no physical possibility of going online removes the obsessive niggle. I have a local repair shop but not 100% confident they are incapable of being idiots. Would you like to help me out for a forum donation?

If you just want to make it difficult for yourself to reinstate network access, simply getting an admin account which is obscure to you to disable the network interfaces in the BIOS set up would do.

Sounds like you could just uninstall your wireless driver to get the result you are after, as long as you have no physical Lan connection.

You need to do step 10 here to disconnect the antennas:

Taking the card out is quite involved on this machine.

Cut the wires if you want to permanently ruin/perfect it.

How the fuck do I find somewhere that is showing the TDF tomorrow in Yorkshire? I want to cycle somewhere, have a pint and watch the final stage, then toddle home. Why is this such a tricky thing to try and do?!

Where in Yorkshire? It’s a big place (God made it that way).

Best value/quality bike tool kit?

What size? Lifeline has a decent quality decent priced entry level kit.

I’m in Leeds, but happy to ride somewhere that’ll have it on/be a worthwhile place to watch it.

The plastic crank bolt on my Ultegra cranks was being a dick to get in so I bought this to replace it. Fitted it, easy peasy, jobs a good'un.....but wont that big hole just let water in? Am I over thinking it...allowing water into the crank spindle? Cant be good, surely.

The MTB ones have a helpful hole the other side for it to all fall out of.
