• I am trying to upgrade an older iMac (2008) from OS 10.6.8 to El Capitan for a disabled client who really needs to use a Mac instead of a PC!
  • EveryMac says it can handle El Capitan if I upgrade RAM. It has 4GB now.
  • I have an Installer file from my own Mac (always keep them when I upgrade). I made a bootable flash installer that mounts and seems to have the proper files, but it won't show up on either Mac on restart holding option key; nor in the Startup Disk list. So, I figured writing to the flash drive must have failed.
  • I partitioned an external hard drive and redid this:

    'sudo /Applications/Install OS X El Capitan.app/Contents/Resources/createinstallmedia --volume /Volumes/MyVolume --applicationpath /Applications/Install OS X El Capitan.app'

  • It seems to work (again) in Finder AND it shows up as a boot option on restart (holding option key), but when I select Install OS X I get an error that the installer cannot be verified. I can't get it to work.
  • So, I figured my installer must have gone bad, even though I successfully upgraded my own Mac with it, and have since upgraded mine to Sierra.
  • Using the App Store I can get to El Capitan, but it will not allow me to download it on my Mac because the system is too new, and I don't want to download it to the old Mac because I want to use an external drive to do a clean install; not an upgrade on the old one.
  • Any advice?

Extract Files

Extract the Ink/Stitch archive into this folder.

Addtitional Steps for Catalina / Big Sur

Newer macOS versions will complain about Ink/Stitch if it is downloaded through your browser. You will receive an error message like this: 'xxxx' cannot be opened, because the developer cannot be verified.

To avoid this error message open your Terminal App. Click on the small magnifying glass icon in your menu bar at the top right corner (or press Command (⌘)+Space). Search for Terminal and open the application.

In the Terminal enter the following command:

Replace ~/Library/Application Support/org.inkscape.Inkscape/config/inkscape/extensions/ if your Inkscape extension folder path has an other location (verify through Inkscape > Preferences > System).

Run Ink/Stitch

Restart Inkscape.

You will then find Ink/Stitch under Extensions > Ink/Stitch.

Full

Upgrade

Delete the old extension files first. Go to the extension directory and remove each inkstitch* file and folder.

ValueError: Null geometry supports no operations

Ink/Stitch on macOS could raise the following error message: [...] ValueError: Null geometry supports no operations.

This error is caused by an incompatibality of the shapely speedups library, which is inlcuded in the Ink/Stitch files.In order to bring Ink/Stitch back to work delete the library as follows:

  • Open the folder of your Ink/Stitch installation (usually this is: ~/Library/Application Support/org.inkscape.Inkscape/config/inkscape/extensions/)
  • Open as well your Ink/Stitch subfolder if you have one
  • Press Ctrl while you click on the inkstitch application file and select Show Package Contents

  • Go into the Folder Contents > MacOS and delete the folder named shapely

I installed Ink/Stitch in my native language, but the dialogue windows are displayed in English

Incomplete Translation

It is possible, that not all strings have been translated. This is indicated by some strings of text beeing in English and others in your native language.If you like to complete the translation, have a look at our description for translators.

Language Settings

We have to distinguish between the Extension menu in Inkscape and the dialogue windows.The selection of the ZIP file causes only the Extension menu to be in a certain language.The dialgoue windows are build differently. They will use the language of your operating system.If Ink/Stitch is uncertain, which language to support, it will fallback on English.You can tell Inkscape explicitly to use your native language as follows:
