How to cure converging verticals in Apple Photos?

If you have an iPhone or iPad as well, use the perspective correction tool on your mobile device. This is easily done, if you are syncing the devices with iCloud Photos. Photos for iOS is currently ahead of Photos for Mac and offers some tools, that are not yet available on the Mac.

On my Mac I am using DxO Perspective to correct the perspective distortion of buildings. It is easy to use.

I don't think you do, except by using it as a manager that sends the image to an editor with those features...
