I got a message that Apple iOS will no longer support certain legacy systems - but they didn't tell me which ones so how do I know?
iMac 27″, macOS 10.14
You should always wait a few iterations of a new OS to get the bugs worked out, that's likely a year from now!
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.
How do I know what "legacy" systems I have?
