OSX Mavericks on a 2011 MBP.
Lightroom hangs while trying to export to LRTimelapse.
Maybe a few photos will export, maybe none.
On further investigation, I try to update Lightroom via Creative Cloud, which then disappears from the screen. ie, crashes, and is not visible in the toolbar.
Tried downloading CC again from the Adobe site but upon trying to install it tells me I have CC already running on the system.
Cue much faffing about while Activity Monitor tells me there's no CC running.
Going round in circles here, worked fine until recently.
Rebooted the laptop, which ran CC automatically.
Updated Lightroom from CC first, it now works again as expected.
Thankfully this worked as trying to update via the Help menu from Lightroom was getting me nowhere!
