After installing Sierra, I can't add Pinterest's "Pin It" button to Safari, or use right click to get the "Pin It" option in the right-click menu.
I go to Pinterest Help>Pinterest Basics>Add Pinterest Browser Button - select Safari, go to Browser Button page, download the file, try to install, and get an error message: Safari can’t install this extension. An error occurred while installing the extension “Pin It Button”.
Mac mini, iOS 10.0.2
What OS and Safari version are you using?
If the problem is still there, try booting into the Safe Mode using your normal account. Disconnect all peripherals except those needed for the test. Shut down the computer and then power it back up after waiting 10 seconds. Immediately after hearing the startup chime, hold down the shift key and continue to hold it until the gray Apple icon and a progress bar appear. The boot up is significantly slower than normal. This will reset some caches, forces a directory check, and disables all startup and login items, among other things. When you reboot normally, the initial reboot may be slower than normal. If the system operates normally, there may be 3rd party applications which are causing a problem. Try deleting/disabling the third party applications after a restart by using the application un-installer or by using the developer’s uninstall instructions. For each disable/delete, you will need to restart if you don't do them all at once.
Thanks - will try that. (MacOS Sierra 10.12 and Safari 10.0)
Issue resolved (without going through the process described above by Eric Root) - another train of thought lead me to this page, https://safari-extensions.apple.com - I scrolled down to "Pin It Button" (with the Pinterest icon), clicked on Install Now - and it worked!
Thanks for this quick fix ^^!!
thank you. i had the problem too and this fixed it quickly and easily. Back to pinning...
