"Fatal Error" after updating iMac

In 2023, I purchased MakeMKV permanently (for my iMac) for ripping blurays. This week, I made major updates to my iMac. Now, when I try to open MakeMKV, I get a message saying "Fatal Error."

What is going on? What should I do? Thanks.

What updates did you do? And what version of MakeMKV are you running?

MacOS 15.4 introduced changes that caused MakeMKV to crash. MakeMKV 1.18.1 & later adapted to the changes.

Thank you!

I purchased MakeMKV (permanently) back in 2023. If I want MakeMKV 1.18.1 now, do I need to pay for it all over again?

So long as you have the key that was sent to you, you can put it in on any computer you own, be it a Mac, PC, or Linux box.

I do still have the key! Definitely!

So, where exactly do I get MakeMKV 1.18.1 for an iMac?

Old versions are all available at https://makemkv.com/download/old/ , so version 1.18.1 would be https://makemkv.com/download/old/makemk ... .1_osx.dmg for MacOS.
