I have recently upgraded to an iMac and transferred my LR catalog from my old PC. Everything transferred properly except for the entire catalog was all under a folder called 'Volumes'. After research on this site, I hid that folder and reopened LR and the folders were all in the correct designated areas and including the external drives, but now LR is taking forever to open. Sometimes 30+ minutes. It is kind of ridiculous. Any suggestions or help would be greatly appreciated! Thank you!
