The main reason: “to change the name, double-click, then type a new name”
I needed this to specify A0 size, in inches, which was hard to find exact dimensions with more than 1 decimal digit, but luckily- unlike ISO 216 – Wikipedia:
[WayBack] The A4 paper size | dimensions, usage & alternatives: DIN A4 measures 210 × 297 millimeters or 8.27 × 11.69 inches. In PostScript, its dimensions are rounded off to 595 × 842 points. Folded twice, an A4 sheet fits in a C6 size envelope (114 × 162 mm).
[WayBack] The A6 paper size | dimensions, usage & alternatives: DIN A6 measures 105 × 148 millimeters or 4.13 × 5.83 inches. In PostScript, its dimensions are rounded off to 298 × 420 points. The matching envelope format is C6 (114 × 162 mm).
If you want to create a document that has a unique size, such as an envelope or card, first see if the paper size appears in the Paper Size pop-up menu. If not, you can create your own custom paper size. Custom paper sizes aren’t available for some printers or for all apps.
Note: The following options might not be available for your printer or app. If these instructions differ from what you see onscreen, refer to the documentation that came with the app you’re using.
Choose File > Print. If you see a Show Details button, click it to show all available options.
Click the Paper Size pop-up menu, then choose Manage Custom Sizes.
Click the Add button to add a new paper size, then specify the paper size you want.
To create a new paper size based on an existing size, select a paper size in the list, then click Duplicate.
To print to a custom paper size, choose it from the Paper Size pop-up menu in the Print dialog (choose File > Print). To set a document size to a custom paper size, choose it from the Paper Size pop-up menu in the Page Setup dialog (choose File > Page Setup).
Tip: If a document is printing with incorrect margins or clipped text, try this: click the Non-Printable Area pop-up menu, choose User Defined, then enter zero for the nonprintable margins. In some cases this allows the document margins to print as expected.
You could go the homebrew way, but that means your system will have two Python installations usually causing a nightmare of path dependency orders. In addition, homebrew puts you on the wrong foot, so:
DO NOT DO THIS!
# brew install pip
Error: No available formula with the name "pip"
Homebrew provides pip via: `brew install python`. However you will then
have two Pythons installed on your Mac, so alternatively you can install
pip via the instructions at:
https://pip.readthedocs.io/en/stable/installing/
I thought it would never happen, but there is now finally an official upgrade mechanism for Homebrew Cask (see [WayBack] Issue 3396 for the implementation)! To use it, simply run this command:
brew cask upgrade
However this will not update casks that do not have versioning information (version :latest) or applications that have a built-in upgrade mechanism (auto_updates true). To reinstall these casks (and consequently upgrade them if upgrades are available), run the upgrade command with the --greedy flag like this:

Schritt 3: tmfs mount
Ein Time Machine Backup enthält doofe Hardlinks auf Verzeichnisse. Das kann Linux so nicht, und man muß das noch einmal mit tmfs fusemounten. Seufz.
# apt-get install tmfs
# mkdir -p /tmfs/tm_kk
# tmfs /hfs/tm_kk /tmfs/tm_kk
# ls -l /tmfs/tm_kk/KK/Latest/
total 0
drwxr-xr-x 1 root root 30 Oct 21 14:26 ‘Macintosh HD’
So your time machine data is on a Linux disk that you export from Linux to MacOS? (as otherwise, I don’t understand what /export/tm_kk/KK.sparsebundle is for)
Kristian Köhntopp:
Yes, I am running netatalk, SMB and NFS on an Ubuntu 18.04.
Jeroen Wiert Pluimers:
+Kristian Köhntopp Thanks. What do you envision as steps to restore a complete time machine?
Kristian Köhntopp:
We will see. I do not see that as normally necessary. Mostly I do not want to lose the work on my laptop, and am just to lazy to restrict the backup to that. In general, it should be possible to create this as a writeable setup so that I get the data back. I will probably never recreate a full runnable mac setup from this emergency offsite backup.
# sudo fsck_hfs -dylS /dev/disk3s1** /dev/rdisk3s1 (NO WRITE)

The italic part is the bad block scanning. The normal part the hfs scanning, which will continue even after finding bad blocks.
If bad blocks are found, output looks more like on the right. If it looks like that, basically you know a disk is toast.
It can be slow, as I did not specify a cache, so it defaults to 32 Kibibyte. You can increase that by adding for instance -c 512m for 512 Mebibyte cache, just read the short help or man page below.
to add a new paper size, then specify the paper size you want.
Luckily,
