El Capitan Cannot Be Verified

Downloaded the El Capitan installer from the webpage, and used the createinstallmedia command to make a bootable USB drive. Everything seems to proceed normally, until 'This copy of OS X El Capitan can't be verified. It may have been corrupted or tampered with during downloading.' Anybody know how to resolve this?

One of the major changes in the macOS Sierra Public Beta isn’t an obvious one, and you may not encounter it until you try to install an app that you didn’t buy from the App Store.

In the Sierra Public Beta, Apple has changed the settings for running downloaded apps. If you really need to run that app and can’t figure out how, it can be frustrating. The settings are found in the General tab of the Security & Privacy system preference.

Note: This article was written for people using the Sierra Public Beta. When Apple released the final version of Sierra, it reverted the settings back to the way it works in El Capitan.

First, how it works in El Capitan

To understand the changes, let’s look at what was offered before Sierra. Previously (or currently, if you’re not running Sierra), in El Capitan. the setting looked like this.

“Allow apps downloaded from” has three settings:

• Mac App Store: The Mac will only run apps downloaded from the Mac App Store.
• Mac App Store and identified developers: When you try to open a new app and it’s not on the list of identified developers that’s saved within the operating system, the Mac tells you it can’t open it. To open the app, you have to go to System Preferences > Security & Privacy, and click the Open Anyway button that appears in the General tab.
• Anywhere: You’ll see a notification that says the new app you want to open was downloaded from the internet, and you need to confirm that you want to open it.

The change in the macOS Sierra Public Beta

The major change is that Apple removed the Anywhere setting. If you had this setting selected in El Capitan and you’ve upgraded to the Sierra beta, you won’t be able to open downloaded apps like you’re used to.

If you want to open an app that you didn’t buy in the Mac App Store and instead downloaded it from a developer on the internet, there are two way for opening the app.

The quick way to open an unidentified, downloaded app in the Sierra beta

1. After you download the app and move it to your Applications folder, right-click on it and select Open.
2. After you select Open, you will see a warning that’s similar to the one below. Click OK to open the app.Sierra adds the developer to its internal list of identified developers so you can open other apps from the same developer.

The long way to open an unidentified, downloaded app in the Sierra beta

1. After you download the app and move it to your Applications folder, launch it. You will see a warning like this one:Click OK. This does not open the app. It simply returns you to the Finder.
2. Go to Apple menu > System Preferences, and then click on the Security & Privacy icon.
3. Under the General tab, look in the setting for “Allow apps downloaded from” and you should see that the app you tried to open was noticed by the operating system. Click the Open Anyway button to open that new app.Sierra will then note the developer and add it to its internal list of identified developers. If you download a different app from the same developer, Sierra will look for the developer on the list and if it sees the developer, the new app will open.

Requirements

• Inkscape Version 1.0.2 or higher

That’s it! All python libraries and external dependencies are bundled (using the excellent pyinstaller), so you shouldn’t need to set anything else up.

Installation

Download

Download the release archive.

Latest release:Ink/Stitch v2.0.0 (2021-05-03)

The LOCALE selected affects the menus shown inside Inkscape. Ink/Stitch dialogs are in the lanugage of your OS (if that language is supported).

Extract Files

Go to Edit > Preferences > System and check where your User Extensions folder is.

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.

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

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:
