Could probably reuse some of

Removed decimal point for memory numbers to only two digits, as it doesn't seem necessary to show them all. (Virtual machine Memory 1024 MB in MacBookPro 2012)

Yes, memory should be rounded to 1-2 decimal points.

Although I'm not sure why it works fine with the system under 1024MB ... XDD

Probably because you have a GPU with dedicated memory while on the system above the graphics memory is "stolen" from the main RAM.

I remembered about it. I wanted to test if I could execute hello under 512MB. First install it under 2GB ram. After installation, replace the memory with 512BM and start executing. Although it can be executed, the network is slightly slower, so I replaced it with 1GB ram it's smoother.

FreeBSD userland info can be removed as it is the same version as FreeBSD kernel.

...until you start updating the system

Why not update the version number of the kernel?

Ask that the FreeBSD developers ;-)

Otherwise, add the graphics card model.

It's already there if it's detected by initgfx:

Then we should start translating it on Weblate.
