This would be great information IF I knew WHICH "existing software" was the issue. I can not tell just from the developer name. How do I find which application is giving this error?
iMac 27″ 5K, macOS 10.15
Does it mention Legacy extensions?
No need to worry, but to see them, just don't upgrade to 10.16 if the developers don't have updates...
About this Mac>System Report>Software>Extensions, click on Obtained from Header, all that aren't Apple are Legacy.
Or does it mention 64 bit apps?
FWIW, it's not an "error", it's a notification of things to come. More info will be forthcoming in the following months.
(Sorry, I clicked on the link in the error message and thought it would include it! And once I click on the link, the error message disappears so I can't refer back to it!)
After I updated the last 2 times I got a message that some application on my computer was using something that would no longer be available after some future date or update. But it does not give me the name of the application, just the name of the developer. I have no idea how to figure out which application that is. I may not even use it anymore and I would like to delete it so the message goes away. Or, if I do need it, I need to know which one it is!
Which error?
This would be a great question if I knew which error. "This error" is hard to troubleshoot.
The problem is the Apple error does NOT tell me which application it is. So I don't know if I even need the application or not.
