Hello Alfred's Baby Daddy,
I'm running Alfred v2 on a late 2011 MacBook Pro, running on Yosemite (10.10.5). I have used Alfred for years without a hitch, and I love this app. In fact, I had no idea just how much I use and rely on this app until it broke for me. However, my problem began when I updated to the latest version of Alfred, v2.7.2 (407).
Upon my first reboot after installing the latest version of Alfred, and every startup since, my shortcut to pull up the Alfred search window no longer works. I use Apple key+SPACE to invoke Alfred, but this does not work anymore. This is regardless of focus, i.e. when I click out of my current program to the desktop and try the shortcut, nothing happens. When I do the same thing within an app, same thing: nothing happens.
Before today, I've been limping along by opening up the Alfred preferences and then quitting same--without making any changes to preferences--and then trying the shortcut again. Amazingly, it would work once more. I've done this 10-15 times, and while a hassle, I put up with it. Today even this move will not work.
I have tried setting the shortcut to a different combination, saving the preferences, and rebooting--same problem with no change. My next thing to try will be an uninstall and reinstall (I hope I don't lose my PowerPack license in the process!). Before I do so, I checked this forum and found no similar complaint. So, I decided to open this report.
