Q: Safari 9 - I cannot install extensions

Hi,

 

since the update to Safari 9 and OSX 10.11 I cannot install extension from the extension gallery in Safari anymore. I click on an extension and the extension window opens but there is no button that says "install now" or anything like that. I have attached a screenshot showing the extension page. Is anyone else having the same problem?

    I can verify this. I've done this before and it worked, but not this time.

     

    To further isolate the problem, I logged in as a Guest User, opened Safari 9 and discovered the Install Button is displaying in the Safari Extensions Gallery. I was able to download extensions successfully. This obviously means the problem is connected to my User ID when I log in. Can you do the same thing when you log in as a different user? If so... chime in. Does anyone know how a User account is connected to the Safari Extensions Gallery and how the rules work for displaying the Install Now button/link?

    This solved my problem:

     

    I had to remove everything from ~/Library/Keychains. Lost all my passwords but I had them stored in iCloud keychain. A few, I had to enter again.

    I was able to fix it by deleting all of the .plist files relevant for Safari - that may be another option in the future if anyone is a bit twitchy about deleting their whole Keychain. The one thing to remember to do in that case would be to export bookmarks.

    I had this same issue and spent a few hours with AppleCare to no avail, so it was eventually submitted to the engineers further troubleshooting. It's been a minute since then but just now I figured it out. Here's what worked for me: After updating to El Capitan, I reinstalled Avast, a third-party internet malware program that provides three levels or "shields" of security, one of them being "Web Shield." I disabled Web Shield protection and restarted Safari and voila, "Install Now" suddenly reappears! I re-enabled the web shield and now it's all good.

     

    Hope this works for you guys as well.

    I have the OTHER version of the problem... -_-

     

    I can install from the store / Safari Ext. page but I CAN'T install from .safariextz files (and so I can't use 90% of the interesting ones...) When I clic a file, it opens the dialog box where I should clic the "yeah yeah I trust this ext.", I do it. Box close. Nothing happened. Ext not in the panel, not copied in the folder.

     

    Tried to wipe keychain, etc. nothing worked. And this is on a CLEAN installation... -_- (I Have a cloned HD with the old installation btw)

    Any idea welcome.

    and on my iMac (updated from Yosemite).

    Just a quick question : do you use little snitch or another firewall or maybe an anti-virus ? I managed to find only that possibility after countless reinstallation / new users to track the problem... I need to run more test (and lose more time...) to be sure but if you don't that means something else is at play. I'm pretty sure now that's a  problem with the keychain though...

    No, I don't use anti-virus, firewall, etc.

    I haven't imported passwords in the clean installation, so maybe the keychain is the problem, but I don't know...

    Thx for the answer. It may be a very weird OS X bug, but I'm trying to check if we can avoid it anyway...

    I submitted a bug report to Apple. The good news is that they have acknowledged the bug. The bad news is that it's a duplicate of another bug (22952398) so they closed my report and I have no visibility on progress other than the fact that it is still open.

     

    I was hoping that the 10.11.1 release might fix this, but alas not.

     

    Hopefully Apple will fix this soon, but in the meantime downloading extensions from another Mac or outside of Apple's extension gallery and installing by double clicking on the extension seems to work.

    I don't know how to fill that report but could you report one with the OTHER bug : some of us can ONLY install extension from the store but not from files / 3rd parties.

     

    27/10/2015 18:55:11,000 kernel[0]: Sandbox: com.apple.WebKit(486) deny(1) file-read-data /Applications/Safari.app

    27/10/2015 18:55:11,000 kernel[0]: Sandbox: com.apple.WebKit(486) deny(1) file-read-data /Applications/Safari.app/Contents

     

    I get tons of those sandbox / deny errors - even with SIP deactivated and permission "fixed" (obviously, something is very wrong with them). And it's from a clean install (tried 3 times... -_-)

     

    Thanks :/

    Posted this a little farther up-thread, wondering if it might help you:

    I was able to fix it by deleting all of the .plist files relevant for Safari - that may be another option in the future if anyone is a bit twitchy about deleting their whole Keychain. The one thing to remember to do in that case would be to export bookmarks.

     

    For reference, I deleted these files, and the entire Extensions folder:

     

    users/[yourusername]/Library//Preferences/com.apple.Safari.Extensions.plist

    users/[yourusername]/Library/Preferences/com.apple.Safari.plist

    users/[yourusername]/Library/Safari/Extensions

     

    You may want to try deleting com.apple.Safari.Extensions.plist and /Library/Safari/Extensions first, see if that fixes it, and if not, delete the com.apple.Safari.plist last (if retaining your general Safari preferences is important to you).

     

    If ~/Library/ doesn't show for you, it's because Finder is set to hide system files. To show them, you have two ways, depending on whether you're comfortable using Terminal commands or not.

     

    How to show/hide system files using terminal

     

    How to show/hide system files using TinkerTool, a Mac app

    >> When you run TinkerTool, you'll want to select the Finder option at the top navigation bar, and click "Show hidden and system files," then click Relaunch Finder at the bottom. You'll be able to find the above folders and files after that.

     

    Let me know if that helps. It did the trick for me, and doesn't require messing with Keychain (which is more of a pain, in my opinion).

    Tried this on my side; no luck at all.   SOOO sad. :/

     

    Btw

    I have the same lines on a fresh account that CAN install the extensions AND output this errors anyway. Crazy. I guess I'll wait for a fix, can't lose more time over this.

    I'm wondering - are there extensions you'd like the actual .safariextz files to save and install manually that way? I can copy & send the files to you, if you'd like?
