updated to macOS Sierra 10.12.2, Lightroom 6.x freezes upon start

[kurkista]

Hi,

today (Dec 21st 2016) I updated my iMac to macOS Sierra v.10.12.2. After that Lightroom 6 (latest version) freezes upon start. Sometimes it does start up, but presents itself with the spinning rainbow wheel, causing the whole computer to slow down, writing this line takes ages as each letter comes with an estimated 2 sec delay.

I have checked forums and blogs but cannot find anything related to my encountered problem.

Has anyone a fix? Downgrading macOS Sierra? I'd rather have something more elegant and less time consuming.

Thank you!

After updating MacOS it is sometimes necessary to trash the prefs. Start by quitting Lightroom. Launch Finder and on the menu bar click “Go” whilst holding down the Optn(Alt) key and choose Library. Open the Preferences folder and trash the two plist files relating to LR6 (see image below)

Then re-launch Lightroom.

N.B. Apple hides the user Library until the Alt key is depressed.

Thank you 99jon,

it sees seems to have done the trick. For some reason in my Preferences list there was only one line: the com.adobe.Lightroom6.plist.

Cheers!
