Guess that means I need to either find my email with the activation code or get it from eSellerate before that date so I can keep things running smoothly on my MacPro1,1, which I still use for MIDI and some emulators (since emulators like Atari800MacX are broken in 10.12 and later due to SDL 1.x no longer functioning).
Edit: Actually, I may have one of the older Kagi registrations and not eSellerate. How should I properly go about making sure I have the necessary files backed up or getting my actual username/code to copy and store?
Edit 2: Found my ooooooold email with the EE2 code. That's getting backed up ASAP. BTW, why is Mojave required for the newest releases now instead of 10.11.6? I know 10.11's Metal drivers were insanely buggy, to say the least, but I'm fairly certain Apple hasn't forced XCode minimum target beyond 10.11.6 yet. I know they will bump it up to 10.12 as the minimum soonish, due to the Metal driver bugs in 10.11 that I noted, but I can't see why Mojave is the minimum required, so I'm curious to learn why.
Oh, and eSellerate's email database appears to have been purged, at least for anyone that wasn't a recent purchaser. The eSellerate portal on the Digital River site appear to be for admin/company users only. The eSellerate store nets a 403 - Forbidden Access error. So it may already be too late for users that aren't packrats like me that didn't keep their registration email or lost it somehow.
