Both plastic laptops and aluminium macbooks are vulnerable to data and graphic leakage, and to scanners. Computer shielding is required to defeat it, but you have to be a bit savvy on how to install it. There is nothing on the internet telling us how to do it. You have to glean your info from certain films that promote it, and from internet contacts. I have been tweeting about it for some time now.

Have a metalworking company make a stainless steel box for you with an open front, measuring 31 inches wide by 23.5 inches high by 23.5 inches deep, and provide a piece of thin plywood to fit inside. Have narrow hooded air slits in the back behind where the laptop is, and a bolt hole in one lower corner. The box would be 1 mm thick.
Also have a backing plate made that is 4 feet wide by 3 feet high by 1 mm thick. It would have large screw holes around it or only three at the top at the left, middle, and right. And a bolt hole in the lower corner.
Put the box on the desk with the open side toward you. Put the backing plate on the wall behind the chair. And pull the desk as close as you can toward you while still allowing the chair to swivel.
Find a company that sells 4.0 (not 0.4) mm solid copper wire and bolt it to the metal. So you've got two wires long enough to go to an earth rod or water pipe somewhere in your abode. This wire has to be solid, not filament or woven or strands. Bolt the other ends to the earth rod or water pipe. There is an earth rod in or under the electric cupboard, and you can put the two ends directly into the ground bar, in particular if it is exposed. If it is not, ask an electrician to do it. Alternatively, bolt it with an earth strap to the cold water pipe that is under the kitchen sink. Or there is a cold water pipe in the electric or gas boiler which might be on show.
This will have connected your shielding to ground earth, and it should create enough push of free ions from the ground to contain your laptops electromagnetic radiation within it, thus preventing data and graphic leakage, and ideally preventing scanners from scanning it.
If for some reason none of your earth rods or pipes work or are not giving a strong enough push, a dedicated steel ground rod can be bought from various companies that you have to bang into wet ground with a sledgehammer. They are also called spikes and they have a bolt on the top. Use a deep scanning metal detector on the ground first to ensure that there are no gas pipes or electric wires in the ground. This earth rod would be about 3 to 4 foot long.
On another note, one can also earth themself. See this website for info:

You might be right, but using computer shielding is best done offline. I suppose you can have the internet connection wire or dongle wire (with usb extension) either inside or outside of the box so as to have an online shielded laptop. But if it is inside the dongle might not work properly.
It depends on what you are writing or drawing on the laptop. If it is just simple little stories, then shielding is not that important. Even doing homework or visiting websites is not that important if anyone can see what your're doing. They will soon get bored with it. But if you're writing a film script or novel, or a report of some kind perhaps identifying people and what they have done etc, like if you're an investigative writer or journalist, then shielding is a must.
I have an offline aluminium macbook in a shielding box with back plate. I am testing it and so far the feedback is positive. There has only been one instance where someone used a common term that I had typed, and I can't condemn them for that. It might be a coincidence or we're on the same wavelength. And also I have a plastic unshielded internet laptop which I only do internet work on, and write and print normal enquiry letters. I am editing twelve main screenplays and I don't want anyone to see what I am doing, so I am doing it on the Macbook.

In the past I have had quite a lot of plagiarism by the media, and quoting of my words and therefore ideas by the news media.
It would be nice if one could just use their laptop without a shielding box, and some people have their room or office shielded instead, but this has to be done for them by professional shielding companies. It involves having enough steel-backed pictures and furniture in the room to turn it into a faraday cage. But the steel is not on show. So one never knows if a room or entire house or apartment is shielded or not, unless you ask the laptop user directly.
