Having Lightroom EXPORT Issues MAC USERS OS X Yosemite 1010.5 – LR 6.0 is stable for exporting. LR 6.2 FAILS to export in some instances. i.e., 2000 or large jpg exports. Roll back your LR to a previous version (6.0) and you can get back to your work of exporting files. ATTN: Engineering I'm here to help if needed to relook at problems with EXPORT on systems such as mine. I'm going to wait a while before I UPDATE L.R.
