hi..
Upgraded to Mountain Lion , Upgraded calibre and nothing is working...
OSX build is ....126A129 iMac is Intel i5 2011 with 12 gig of Memory ...
Calibre is latest down load..
When I say nothing happens, basically interface starts but no library can be selected..
Have a Mac Book Pro still on Snow Leopard and all is well using new release of calibre..
Any advise ??
