I\'m unable to install almost any of the Paw extensions. Unfortunately several of the ones that won\'t install are the ones I really want! :)
I\'ve tried almost all
It's now fixed in Paw 2.2.5, which is ready now on the website, or in a couple of days on the Mac App Store.
It seems to be a "problem" with El Capitan. According to this question, iOS 9 and OSX 10.11 require TLSv1.2 SSL for all hosts you plan to request data from unless you specify exception domains in your app's Info.plist file.
I tried to manually edit Info.plist and add
<key>NSAppTransportSecurity</key>
<dict>
<!--Connect to anything (this is probably BAD)-->
<key>NSAllowsArbitraryLoads</key>
<true/>
</dict>
But, after that, I just could not start Paw anymore and got the following line on console
07/10/15 00:39:15,398 com.apple.xpc.launchd[1]: (com.luckymarmot.Paw.103392[905]) Service exited due to signal: Illegal instruction: 4
