1. The exact message is one of those that appears in the link I posted: “This copy of the Install OS X El Capitan application can’t be verified. It may have been corrupted or tampered with during downloading”.
2. Here is a simple solution to fixing the error message while trying to download your Apple Operating System to Macbook Pro Air via USB drive. If this doesn't.
3. Apr 01, 2016 “This copy of the Install OS X Mavericks application can’t be verified. It may have been corrupted or tampered with during downloading” The reason why this insane message is happening is because as of February 2016, the security certificates that validate these Mac OS X installs seems to have expired.

If you are trying to install a fresh copy of Mac OS X 10.11 El Captain after downloading it from the App Store and you are using a bootable USB drive, you may receive an error message right before the install kicks off.

This copy of the Install OS X El Captain application can’t be verified. It may have been corrupted or tampered with during downloading.

El Capitan Cannot Be Verified Full

This error message indicates the MPKG mechanism for checking the application installer checksum (used for proving the install files are valid and from Apple) files failed. It basically means Mac OS X will not proceed installing a copy of El Captain because it can’t prove its authenticity – even if the installation is ok. You can still push forward and install Mac OS X El Captain. Follow the steps below.

Everyone Says: Check the System Time on Mac

Apparently, the system time on your Mac may be off causing the El Captain installer to think your system date is way off. This happens if your onboard motherboard battery is toasted. Check the date to ensure it’s right – follow these steps.

1. Cancel out to the installation (If you are still on your bootable image of El Captain). Go to Utilities -> Terminal.

2. Type date. If your date is correct, then proceed to the next section below. If it’s not correct, continue with these steps.

3. Set the current date and time. In Terminal, type the following command in this format shown in example below date MONTH(02)-DATE(28)-TIME(01:51pm)-YEAR(15)

Hit enter to apply the new date. It will display. Now, attempt to install El Captain. If it still fails with the same error message, proceed to next steps below.

Force Install El Captain Terminal Command

If your confident the install you just downloaded from the App Store is valid, just use Terminal to force install it. You can do this while still booted from your USB Drive or media. Follow the steps below.

1. Type the following command into Terminal, replacing with your Volume names.

2. The install should kick off and you’ll see in Terminal “installer: OS Install started”. Wait for it to complete then reboot.

If all else fails, let us know. You may actually have a corrupt copy of El Captain in the end – maybe you disconnected your USB Jump drive incorrectly causing the files to become corrupt. Try re-downloading El Captain and re-copying it to your media.

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:

• Go to Edit > Preferences > Interface (Ctrl + Shift + P)
• Set your language
• Restart Inkscape
