Using LR 6.x, the LR catalog and corresponding images are stored on an external disk. Opening the same LR catalog on two different macs shows different picture counts. Can't figure why. Any ideas?

Check to see if there are collapsed stacks,

Exactly. I try to not use stacks for this reason—I am always confused when I have stacks.

Just to be clear—for many data that you keep about a file, if you "write metadata" then the two catalogs should be in synch as long as you haven't created any conflicts (check metadata status in browse mode). But some data, like stacks, collections, and "Pick/Normal/Reject", are not written to the files, so can be different in every catalog.

The OP says he/she opens the catalog from the external disk so ít's the same one. When there are collapsed stacks in situation 1 this will be the case also in situation 2 i think.

However, i don't have an explanation for this..

Yes, but both computers will store their own local version of the Lightroom preferences file. That is where any differences could come from.

Now fixed. Not sure what exactly fixed it. On the mac where the count was lower, I LR sync'ed the whole disk folder, and then outside of LR, on the internal mac HDD deleted all Lightroom files or folders on both macs (just in case). When I then mounted the external disk to the other mac, the picture count was the same., showing the lesser same amount of both. The only thing, on the mac where it originally showed a greater count, in the LR cat, I lost a few catalogued pictures that I worked on a few days ago, and had to re-import them.  Probably those pictures that made difference in count originally. Both macs has LR are at level 6.12. 

thanks.
