I have previously calibrated this, but you need to know the right brightness.

If you are doing prepress, then you want it at 80-120 and the room should be dark.

Make sure to select no, otherwise you can't see the calibration menus. Now it asks whether you want a black background.

So first plug in the Spyder3 to your Mac and it should detect it and download some software. So when you get the first screen, it will ask you about downloading. First of all, there are no real instructions for this as it's a pro tool.Installation is easy with brew install displaycal which is great!.So here are notes on how to make an old Spyder3 work with Displa圜al: Well, with all this pandemic isolation time on me, I've been fixing the house and thought I'd give it one last try before trashing the Spyder3 and getting a new calibrator (more on that below). There is an open source project called Displa圜al which dispenses with the proprietary software, but for the last year, every time I've tried to use it with the Spyder3, it has crashed. So my monitors have not been calibrated for a long time. This is the Spyder3 and about three years ago, DataColor discontinued support for it. There are newer ones out there, but for a device that I literally use once a year, it seems sad to have to buy a new one. Ok I know this sounds little strange for an electronic gizmo, but I've had for 10 years, the same color calibrator.
