I took the plunge the minute version 6 appeared to hit yesterday morning 10/27. I called and got my upgrade (purchased 33 days ago) and had the Silver library. I was feeling bold and decided to also upgrade to Platinum.
Background: Macbook Air 2011, 1.8 GHz Intel Core i7 4GB Ram and 256 SSD HD.
OSX 10.10 Yosemite... So a decent machine ready to handle the next update.
It took me downloading the final v5 update... applied it, restarted then got version 6 within another 1-2 downloads and an hour or so. That was yesterday around noon (when the homepage was having problems).
Since then, it's been downloading the library to Logos... and it's driving me crazy. I've restarted about a dozen times... applying new titles, synchronizing... downloading... repeat.
Last night, I left my machine on - preventing HD from going to sleep trying to get a final 4GB updated. This morning I got to 2GB... then around 11am today, I am under 1GB (700MB) and it's still cranking.
What is really bad is that my fans have been humming along for no real reason. The Indexing is over 150% CPU and energy, forget about it. Drains my battery in an hour or so. BAD.

I was told by support it may be the Apple wifi issue from Mavericks days... I don't buy it. If that's the case, then Logos should have split up the download packages for Mac users... OR looked at a better method to categorize the library updates as I am sure they have a ton of people doing what I did with v6.
Oh, and I've also had to kill the LogosCEF process a half dozen times as it goes unresponsive. Strange.
SO I am running the logging tool now to show that something is wrong. I suspect no one tested my corner case - upgrade to 64bit, new version, new library... and if they did, they obviously didn't optimize download servers / instances in the cloud. Because this is pathetic. There really needs to be a better install / upgrade path.
Any suggestions?
Thanks!
Dave
