The first complaints related to the new iMacs began to appear in the discussion forums on the Apple website, restricted so far to the 27-inch model. Some different topics are covered by users, but most of them cover the area where the manufacturer has made the most changes in this generation of the desktop: performance.

Two problems have to do with the latest version of Adobe Flash Player: several users report that playing content from the Safari plugin displays poor results including extremely slow video and distorted audio. In addition, the plugin's CPU consumption reaches much higher values than normal, something that can be checked from the Activity Monitor (Activity Monitor) of Mac OS X.
In the midst of several attempts to solve these problems, from restarting the machine to reinstalling the operating system, none of them were successful, offering only temporary results. However, there are other shortcomings in addition to these being reported, including builds corrupted Snow Leopard pre-installed, anomalies with permissions and even strange behavior of hard drives.
Fortunately, not all machines are experiencing problems: the MacNN informs that one of the users of his discussion forum managed to replace the defective machine with a new one, and now everything works perfectly. Other sites that received 27-inch iMac units for testing also didn't notice anything strange, within what has been discovered so far.
