Good to hear many of you are using Mavericks succesfully. I did an upgrade install 2 weeks ago. No go - many crashes. The did a fresh install on a 4 TB Hitachi drive and went through nightmarish gyrations getting it to work on my 2009 3.32 Quad Xenon with 32 GB Ram Mac Tower. Ultimately, I did a fresh system install over the original fresh install and that seemed to fix the problem.
There's a lot to like about Mavericks - the finder improvements, of course, and several other things. I've had to buy a lot of software I hadn't planned on, but I'm using Photoshop CC now and it's very cool. I do have Photoshops CS3, CS4, and CS5 extended installed as well, and they work fine, happy to say (long story why I need each of those PS's).
Lightroom 5 is great.
The one thing I miss the most is an older program called iView Media Pro (pre- Redmond and Phase one) which was an awesome program that I can hardly live without.
I do have VMWare Fusion and I run a few Windows programs on that, but I'm going to install Snow Leopard Server on Fusion so I can run any programs that are Legacy or anything else that runs on Rosetta.
If anyone is aware of any software that equals iView Media Pro, that is current, please let me know.
Printers synced up immediately with the exception of the little Cannon Pro-100 - it was tricky getting it to work - thank goodness for the internet and people who post solutions.
Our HP Z3200ps 44" hit the ground running - never lost any profiles, etc. It was a dream.
Have not tried to use the Epson 4800 Pro yet - will wait on that for awhile.
All in all, now that I have several backup copies, all my eSata devices are working well (upgrades on Caldigit), etc., I'm fairly pleased with it.
Admittedly, I cringe every time I see the circle going round and round on the grey apple boot up screen, but now that I know that an "install-over" works perfectly, I guess it's time to relax, but easier said than done.
The most important thing - my Gretag i1 no longer works with Mavericks. So just got an i1 Display Pro and it is a dream to use, even with the secondary monitor workaround.
I'm more happy with Mavericks every day....
