Lightroom 2015.14 won´t start

[bekafi]

Hello everybody

First some tech information:

Mac Pro Trashcan running OS X 10.9.5  (updating the os is not an option)

Lightroom 2015.14

Everything worked fine for several years. Today I tried using Lightroom for the first time in 2018 and it crashes all the time I launch it with the well-known error message that it was unexpectedly shut down. I tried a few times and got the message that my preview-cache was unreadable so I deleted it, but that didn´t help at all. According to Adobes Compatibility Chart my version of Lightroom should run under OS X 10.9.5.

Any help would be appreciated

Hi Benjamin

Are you using the stand-alone version or the CC version?

If you can launch Lightroom, from the menu go to:

Help >> System Info

You should see something like this for example:

Lightroom Classic version: 7.1 [ 1234567 ]

License: Creative Cloud

Please reply with the following information

Version

[Build number]

License type.

Version: 2015.14

Build number 1149743

I have the whole CC

But I guess I found my mistake, I thought version 2015.14 was earlier than 2015.6.  Interesting though that I was able to install a version that is not compatible with my OS directly from my CC App.

In the CC Apps tab click the pull down menu next to Open or Install, to see older versions. Or go to the link below:

Download Photoshop Lightroom

Your version of Lightroom will not run under OS X 10.9.5 (nor will Lightroom version 7.1)

You have to downgrade your Lightroom to 6.6.1, or upgrade your operating system to 10.11 or later.

How do I do that downgrade of lightroom? The CC Application doesn´t show me any possibility to do that.

You really want to roll back to Lightroom 6.6.1
