Although I had no problems or complaints with Seattle Avionics, I decided to try the new Airmate product.
The Airmate store seemed overloaded yesterday when I tried to purchase the US product. I was finally able to get through later last night and made the purchase. It took overnight to get the acknowledgment email. Also this morning I received an email from Airmate (Laurent) asking for my SkyView serial number and N-Number. Another email followed shortly with an account using the N-number and included a password. I downloaded their Mac Data Manager and am using it as we speak to download the data. It is not fast, but maybe that is because of the initial high demand after Dynon's announcement. Note that it offers its own (Airmate) USA aviation & obstacle database. Not sure if I will load that one or stick with Dynon's own database. The other files reside on the USB stick, just like Seattle Avionics files did.

UPDATE: The downloading of the USA VFR Sectionals seemed to have stalled, so I closed the Data Manager Program and restarted it. Luckily it started downloading where it left off. Then the downloading of the USA/Mexico IFR Low Charts also seemed to stall, so I closed the program again, restarted it, and the download picked up where it had left off. After the downloads were complete (and it's not obvious when that happens), you have to click the "Program USB stick" to have the program unpack the files and save them to the USB drive.
My initial observation is that Airmate is not much, if any, faster than I have experienced with the Seattle Avionics Data Program Manager on my iMac running Parallels with Windows 10 or 11 (in fact it's still unpacking and writing the data to the USB drive after the downloads completed). You can't get around the fact that there are a lot of data files to download, unpack, and write to the USB drive.
