First, be aware that installing PostgreSQL on a Lion system will add a new postgres user. That user needs to be left intact. If you attempt to remove the postgres user, it will prevent PostgreSQL from working. Also note that you should install Resolve as a user with Admin privileges.
Below is the standard info we send to folks with database issues after an initial Resolve installation. If this doesn’t help, please contact us at davincihelp (at) blackmagic-design.com so we can go into more detail on the issue.
When you install Resolve, the PostgreSQL database application is also installed, and this is what Resolve uses to store project data. Sometimes, PostgreSQL does not install properly, and then you see the database could not connect message.
Look in your Mac Applications folder, and see if you have a PostgreSQL 8.4 folder there. If you do, open the folder and run the Stop Server app. It will likely give you an error message, but that’s OK. Now run the Start Server app. It will either start the server, or give you an error message. If it DOES start the server, then launch Resolve, and see if its happy now. If you see a guest and admin user login icon, then everything is good. If you get an error message when you run Start Server, grab a screen shot and send it to us.
If you don’t have a PostgreSQL 8.4 folder in your Mac Applications folder, then open a Finder window and select the /Library folder. In there, you should see a PostgreSQL folder. Using Finder, rename the PostgreSQL folder to PostgreSQL.bad and then reinstall the Resolve dmg file. You do not need to do an uninstall first, just install Resolve again. After your system restarts, look again in your Mac Applications folder. If you now have a PostgreSQL 8.4 folder in the Applications folder, things are probably good. If you don’t have a PostgreSQL 8.4 folder in the Mac Applications folder, let us know, and we’ll send you a more comprehensive fix for getting PostgreSQL installed. Otherwise, continue below.
Launch Resolve, and see if it has a guest and admin user now. If so, you are good to go. If not, follow the process above to manually run the Start Server app (run Stop Server first). If that’s happy, and launching Resolve still does not show the guest and admin user login icons, then open the Database Manager on the Resolve login page, and see if there is a database listed. If there is, highlight it, and click Select. If that works, it should close the window, and you should see a guest and admin user login icon. If clicking Select does not work, it may tell you the database is not compatible. If so, click Upgrade. After that’s done, then highlight the database in the list, and then click Select. If you don’t have a database in the list at all or you can’t make a database that is listed work, click Create. Take all the defaults shown except the Label and DB Name. Use something like resolve in both those areas. It can be any name you want, but the DB Name must be lower case, and not contain spaces or special characters. Once it’s created, highlight the database in the list, then click Select. Now you should have a guest and admin user.

If you use 2 Q4000 cards, the one used as the GUI card will not provide any GPU processing.

I suspect that if you remove one of the 4000 cards and move the GT120 into that slot, you will have better performance.

It’s very important that the GPU AND GUI cards are in x16 PCIe slots. Your problem is likely because you have the GUI card in Slot 4, which is a x4 slot.
To answer the next question, no, you can’t put multiple GPU cards in the Mac chassis. You must use a PCIe expansion chassis if you wish to have multiple GPU cards.

Nothing to do with Red support. The OSX 10.7.4 update created an issue with the Resolve openCL GPU handling that we use with AMD/ATI GPU cards/chipsets. 8.2.1 beta 3 has a fix for the issue.
If you were running OSX 10.7.3, then Resolve 8.2 would have worked OK for you.

Are you using the 8.2.1 beta 3 version of Resolve Lite? That’s what you HAVE to use if you’ve done the OSX 10.7.4 update and have an ATI card.

Do you see the clips OK on the Browse page, in the Browse page viewer? What type of system are you on? What type of graphics card(s)/chipset does your system have? How much VRAM does the graphics card(s)/chipset have?

As per the Resolve Windows Config guide, the Quadro 600 is the lowest end GUI card we recommend.

I did this test. This was not a test of rendering ability or speed. This was simply a test to see how much having 2G of VRAM on the GPU card over 1G of VRAM would help, as far as getting the “Error running GPU algorithms. GPU memory might be exhausted” error message.
As noted, it helps a lot.
Regarding the GTX580 cards, yes, we recommend using the 3G cards over the standard 1.5G cards, since these are the 2 standard available sizes.
But you would not normally put a GTX580 card inside a MacPro chassis. You more likely will have a GTX285 or Quadro 4000 card. The Quadro 4000 is preferred, since it has 2GB of VRAM stock, making it a much better choice than the standard 1G GTX285 for high resolution timeline grading or rendering, even though the GTX285 has better performance. Now that a 2G GTX285 is available, that might be a better choice for people, if they are in the process of deciding what GPU card to get when putting together a Resolve on Mac system. For Lite users, who can’t use timeline resolutions higher than 1920×1080, this is not much of an issue.
I realize that with the new NVIDIA 270.00.00 driver under Lion, you have a wider choice of GPU cards you can use, but the Mac 2G GTX285 will work in Snow Leopard or Lion with the standard Apple NVIDIA driver.

There was an issue with applying corrections from a Mem or Still in Unmix mode. It has been fixed in the 8.2.1 software, available on the web site.
