Lightroom catalogue parent folder permissions issue

Hi guys,

Im having an issue with not only my 2011 Macbook Pro that crashed thanks to the infamous faulty Radeon graphics card but also with the task of opening my backed-up Lightroom catalogue from Time machine on a new Mac.

I have 8 years of edits in this folder that I can no longer access on a different machine. Any help with this would be hugely appreciated.

The message I get reads as follows,

The Lightroom catalog cannot be used because the parent folder “/Volumes/Time Machine Backups/Backups.backupdb/Macintosh/2014-09-25-102018/Macintosh HD/Users/jules/Documents/Backups/2014-09-19 1324” does not allow files to be created within it.

Thanks in advance for your help.

Jules
