Lightroom 5 cannot be registered on a new Mac

Hello, I have been meaning to purchase a new computer for a few years now, as my 2012 iMac 27" just wasn't able to process most functions any longer and certainly not Lightroom 5. I was able to download and install Lightroom 5 onto my new Mac Mini, but when i submitted my serial number to register the product, Adobe rejects it. The application still seems to "function" but I have come to realize it's no longer supported. I wanted to simply migrate my Lightroom catelog from my old iMac to my new Mac Mini and start catching up on the last few years of photos. 

 

I'm a hobbyist and mostly just have family photos and sightseeing. I'm not a professional. I just want to be able to use the software I purchased. If i MUST subscribe, I can...but $240/yr for a hobby seems....steep. 

 

Seeking any help or assistance from the community on the best way to move foward here. 

 

Summary:

 

1. Old 2012 iMac 27" with LR5 that has thousands of photos.

2. Brand new powerful Mac Mini that can handle those photos, and import my newer ones

3. Purchased and loved Lightroom 5 years ago, would love to keep using it.

4. Not opposed to the subscription model, but the price is steep - is this really my only option as someone that has purchased Lightroom software and should still "own" it?

 

Thanks!

I'm not a Mac user, but Lightroom 5 isn't compatible with the new MacOS versions. I'm surprised you were able to install Lightroom at all.  Newer MacOS versions are working only with 64bit applications and the LR installer is a 32bit application and this cann't be run on the newer MacOS.

No chance. If you like to use Lightroom in the future the only way is to buy a subscription.
