It seems like sandbox apps are having some issues with OS X Mountain Lion 10.8.3, others instead solved them with this latest update Apple's operating system.
Problems in the previous version of the OS X 10.8.2 operating system were mostly reproduced in the form of unexpected restarts of the application, even sometimes of the Macs or system crashes quite annoying for the user while using this cool app.
Well, it seems that this type of Pixelmator bugs reported by some users of the application, will no longer be reproduced. Mountain Lion 10.8.3 update released last week solve these kinds of problems with the image editor according to its developers.
We read in the official blog of the application:
Since Apple released this update for Mac computers, we've done a lot of testing to try and reproduce the issue that some users previously reported to us on our support page. These problems, which were basically reproduced on Macs with Nvidia graphics cards installed, seem to have come to an end with this OS update.
Far from hiding the problem reported by their users on some Macs, the application developers faced the problem and recognized that it existed, but they could not solve the problem on their own and many emails were exchanged to try to solve the problem.
Therefore, the Pixelmator team appreciates the work of Apple and Nvidia for putting up with the emails exchanged with the two companies and solving the problem in subsequent versions, as it has been.
We remember that this application called by many as 'photoshop's little sister' We will find it in the Mac App Store and it is one of those applications that we recommend for those like me, who do not master the art of Photoshop and want to retouch their images without spending so much money on the application and that in return offers some possibilities less than the Adobe program.
