My mini's been prompting me about the new OS X upgrade to Mavericks. I finally got around to checking with Elgato to see if EyeTV had any known problems with it. Only issue they've found is with a multi-monitor setup, something I don't have to worry about for my TV. So I went ahead with the upgrade.
The download took almost an hour, so I made sure to copy the installer before running it. I did this as the installer will delete itself after it finishes, presumably to free up the 5.31 GB of space it takes, and I didn't want to have to download it again when I get around to upgrading my MacBook Pro. I'm holding off on that as I've less than a week to go to finish Stay Frosty 2 and I don't wish to risk any problems with my development setup at this time. I had a situation after one OS X upgrade where Parallels wasn't happy - and Parallels is critical for Stay Frosty 2 as I use a Linux VM for the ARM compiler that's used for Harmony/Melody development.
The upgrade didn't have any issues, though I did have a minor panic when it rebooted and switched to 1080p (which my TV doesn't support) and I couldn't remote into it from my MacBook Pro. I dug out my extra monitor and plugged it in and discovered it was still installing the update, which is why the screen sharing service wasn't active yet.
Once it was done my settings were restored and the mini correctly switched back to 1080i when I plugged it into the TV. I watched a few recordings and everything seems to be fine.
