I have a Mac laptop running Yosemite and Lightroom 5. It is under 12 months old, and has 16GB of RAM. Its hard drive has 6.01GB free out of 120.12GB. The last time I shut down was earlier today. I have never run a cleanup program.
I had created two catalogs, but deleted one which was a practice one. I will have to look into the size question. I searched "lrcat" under documents and the files in the attached photo popped up. How do I determine size?
Thanks for your help!
