I have an older Intel iMac at home, which is mainly used for browsing, chatting and movie viewing. Watching DVDs from different regions, I was forced to switch the region a couple of times, but alwas was careful to keep the last switch to make sure it ended up in my own region. But when I wanted to make the final switch, I was met with an unexplainalbe error code. I tried everything, but the issue couldn’t be fixed – even the local Mac store said there was no fix, and the guarantee wouldn’t cover either. So I left it that way for maybe a year and a half.
For some reason I gave it a new try recently. To my surprise I succeeded. I finally found a firmware patch for the MATSHITA DVD-R UJ-857D Drive. Now my drive is region-free.
DISCLAIMER: If you choose to follow any of the following instructions, it will be at your own risk. You DVD drive may break.
The patch was found here:
Only problem, the patch would not run on Leopard, only Tiger.
From an Italian web site (thanks Google Translate) I learned how to fool the system into thinking it’s version 10.4. Here’s how:
Open Terminal and type:
sudo nano /System/Library/CoreServices/SystemVersion.plist
Change the version numbers to 10.4.9 and exit by hitting ctrl-x and then y for yes to save.
You can now run the patch.
Remember to change back the version number before you restart the computer, or you it get’s really complicated to change it back.
There’s a application called Region X, which can be used to make changes to the region or even make the drive region free.
