Final Cut Pro X (10.0.3) and ColorSync

Posted by on March 11, 2012 | Comments Off on Final Cut Pro X (10.0.3) and ColorSync

I’m doing a lot of work in Final Cut Pro X at the moment, and got off to a terrible start when every clip I tried to preview / play caused the application to lock up, while leaving me in control of the rest of my machine. Innumerable “Force Quit”s later, I spotted a post on Apple’s discussion boards indicating that this is to do with using a non-calibrated ColorSync display profile. It looks like Apple have re-introduced a bug that they claimed to have gotten rid of in version 10.0.1.

A screenshot of the displays section of System Preferences


If you are unable to play or preview media in Final Cut Pro X check that you’re using the correct profile for your display in the Color section of the Displays area of your System Preferences. There is some guesswork involved here, as you can see in the screenshot of my own Colors section – the “SyncMaster Calibrated” profile doesn’t work, for example, and there are 6 undifferentiated “Display” options. I went with the one at the top of the list, though examining the Colorsync Profiles themselves, there do seem to be differences between them…

Digital Watchdog DW Mac ACS preferences

Posted by on September 15, 2011 | Comments Off on Digital Watchdog DW Mac ACS preferences

A client using Digital Watchdog‘s VMAX system for video-monitoring of his home has recently been having troubles getting his settings to “stick” in the Mac client app. We eventually found the file in the user’s Document’s folder, named “dwacssite.lst”. Deleting this file, or altering it’s permissions to allow read / write access should restore control to you.

If you own a compatible Digital Watchdog DVR box, you can download the Mac ACS app from their website. They also provide a free iOS client.

NVidia GeForce 7300 GT Issues

Posted by on December 24, 2010 | Comments Off on NVidia GeForce 7300 GT Issues

Pierre Igot tracks an apparent issue with 7300GT video cards in Mac Pros here, here and here.

Although his problems seem to be gone now, he mentions “channel exceptions” in the system log, garbled display, and intermittent freezing, resolved only by a restart. Trouble began with 10.5.6 update. Card was reseated and dust removed, and software updates applied. Notes that NVidia seem to be working on a replacement driver for Mac OS X, available here.

Similar issues (intermittent hang, often on startup, video distortion / line on screen in WIndows & OSX after startup) with own recent client resolved by:

• Unplugging portable external hard drive from powered USB hub, also attached to several other high power devices.
• Rolled back recently failed install of driver updates in Windows Vista, under BootCamp.

Safari 5.0 speed issues, and potential resolution

Posted by on July 6, 2010 | Comments Off on Safari 5.0 speed issues, and potential resolution

Since updating to Safari 5.0, I’ve noticed that it seems to hang frequently, partway through loading new pages, but before blanking the window or displaying any of the new information. Sometimes it will work its own way through the slowdown, but more often I find myself forced to click back and then forward again, or hitting refresh multiple times, in an attempt to force the page to load.

According to a piece on today, the problem is “anecdotally” traceable to Safari being a little overzealous in its attempts to anticipate our every need, and dispatching what many ISPs’ servers deem to be an excessive number of DNS requests in preparation for the user’s next click. The solution, as seems to be the vogue at the moment, is to direct your computer to make use of the free, and incredibly useful, OpenDNS service.

To use the OpenDNS servers instead of the ones provided by your local router:

Open up “System Preferences” from the Apple menu
Select “Network”
Select your active network interface. This would be the one at the top of the list on the left, with a green light next to it – usually AirPort or Ethernet…
Click on “Advanced options…”
Click on “DNS”
Click the “+” button at the bottom left of the DNS pane, and then type into the text box.
Click the “+” button again, and type into the second box.
Click “OK”
Click “Apply”

et… voilá! Safari 5, with all the speed I had come to expect: no need to try to downgrade to version 4!
