A month or so ago, after the most recent OS X update (10.8.2), we’ve bumped into a problem that causes certain Macs to restart when intensively using Pixelmator. Sometimes, the app would stop responding without restarting a computer, or just cause some graphical glitches.
We did everything to find the root cause of the problem. We’ve researched a vast amount of information about OS X internals. We’ve torn down our Macs. We even reached out to Apple. Finally, the picture was clear: It’s an issue with NVIDIA GeForce graphics card drivers.*
Although the issue isn’t with Pixelmator, we didn’t give up. We’ve searched for various workarounds, and then, we checked with you to see if any of them helped (thanks so much for being so patient and for taking the time to test those workarounds). But in the end, nothing worked.
Good thing, though—the guys at Apple are very helpful, and as soon as we hear about a solution, we’ll let you know about it that very moment.
To prove our commitment to you and to brighten up the holiday spirit, we are soon to release a Pixelmator 2.1.4 update that comes with tons of quality improvements.
* The following Macs with NVIDIA GeForce graphics cards are currently affected: GT 120, GT 320M, GT 330M, 9400M, and GT 9600.
