MacOS, Disk Utility, encryption

In the past few days I updated MacOS to current, and bought another external backup disk, a Seagate such as I have used before. These two events have no obvious significant causal relation, but jointly they muddle the causality of an unpleasant surprise:

I go to Disk Utility to format the new disk, intending to make it "Mac OS Extended (Journaled, Encrypted)" like the others. (I rotate at least three backup disks, keeping one elsewhere.) I find that encryption is not on the menu – though it seems that I could reformat an already encrypted volume to "APFS (Encrypted)".

Disk Utility also does not allow me to partition the new disk.

Is there something strange about the disk, or has Apple turned against encryption, or what? —Tamfang (talk) 03:29, 17 September 2021 (UTC)

Download wikipedia database in txt format

Hello, esteemed wikipedia team.

I would like to clarify some things related to loading the database in different languages. I have already read many articles about wikipedia dumps, but they are all offered in XML and SQL format, while I need pure text. On top of that, the final unpacked versions weigh over a terabyte. My question is: can I find a source where I can download all wiki-articles in plain txt, so that the final size does not exceed 100GB per language? Thanks infinitely in advance for the answer. 79.170.111.146 (talk) 05:37, 17 September 2021 (UTC)

For English, French, German and Portuguese you can download separate dumps, which do not exceed 20 GB. See meta:Data dump torrents.  --Lambiam 09:23, 17 September 2021 (UTC)

Why? (macOS Mojave)  --Lambiam 09:52, 17 September 2021 (UTC)

It is most likely System Integrity Protection, very similar to SELinux. You have to either turn off SIP or specifically enable full drive access to the terminal. 97.82.165.112 (talk) 13:44, 17 September 2021 (UTC)

Thanks, that must be it. I think it is a bit silly root is not even allowed to see the names of the files in the folder, even though I can access and open them without problem using the Finder.  --Lambiam 09:51, 18 September 2021 (UTC)
