The Lightroom catalog cannot be opened because it is too new to be used by this version
Hi there,
I have been using Lightroom Classic on my iMac 2015 model for almost 9 years, and I have one catalog that has everything on it.
I use an external drive that has both my catalogs and photos, and run Lightroom through that.
Recently I took the hard drive to work, and used it to run Lightroom on a 2022 model Macbook Pro to finish off some freelance work during my lunch break.
Back at home today, I tried to open my reglular catalog, but I got this message:
The Lightroom catalog named “my catalog" cannot be opened because it is too new to be used by this version of Lightroom. Would you like to select a different catalog?
With my iMac being old, I am unable to update to the latest version of Lightroom, which my work MacBook Pro uses, and I am guessing its updated the catalog to that.
My questions are:
• Is there anyway to roll back the catalog so I can use it on my older iMac?
• If not, is there a way to salavge the catalog so I can use it on my older mac?
There is around 2 years of missing edited images from the last catalog I have before that, so if I can save it I would be so happy.
Any advice will be greatly appriecated!
