To me this is the biggest difference between Safari and IE/Edge. Microsoft provided free VMs that you could download with all supported versions of IE and Edge.

To me this is the biggest difference between Safari and IE/Edge. Microsoft provided free VMs that you could download with all supported versions of IE and Edge. So you could test sites and investigate bug reports. With Safari you can't debug an issue without expensive Apple hardware. I was happy to keep my sites compatible with IE and Edge (maybe not constant testing but some manual testing after big changes). However no way I was going to do that work for Apple when they didn't help out at all. (The Edge VMs don't appear available anymore but since Edge is cross-platform and free it should be easy enough to install it in your own VM or on your workstation.)
