Thank you for replying.

the app is : https://www.myheritage.com/family-tree-builder

once downloaded, verified it cannot be opened . Msg says it encountered a problem and needs to shut down.

i tried multiple times, deleting and reinstalling the app without success. Before the update I had it on my Mac and it worked fine.

 If in doubt I would refer to the developers website:

Support/Help/FAQ/known issues/compatibility /updates...

Contact a third party vendor
