Despite hype from Apple, Mac OS X 10.5 Leopard appears to be somewhat rough around the edges. Earlier this week, we quoted a report by a security researcher who said the new Mac operating system's built-in firewall was a mess, improperly blocking traffic and causing compatibility headaches with applications like Skype.
eWeek now reports that Leopard also suffers from a serious bug related to file copy operations. The bug occurs when the connection is accidentally severed as users attempt to move files to or from removable devices or network drives—say someone trips on the cable or the network disconnects. Instead of simply canceling the transfer, Leopard causes the file that was being moved to disappear from the source device, even though the move operation was incomplete. Considering most Macs lack additional hard drive bays and therefore require users to plug in external drives for extra capacity, the bug is potentially quite damaging. A video of the issue in action can be viewed on this blog.
According to another eWeek report, the firewall and file moving operations aren't the only problematic areas in Leopard. The report also mentions Wi-Fi problems and incompatibilities with Adobe software including InDesign, Photoshop, and Illustrator.
