Parallels Desktop has been updated to version 9.0.24237 with some fixes for issues related to the upcoming OS X Yosemite. The release fixes a crash that occurred when starting up Parallels Desktop 9 when running Yosemite, and it squashes a bug related to dragging and dropping files between Macs with Yosemite and virtual machines. It also removes a black screen that appeared on startup when running Mavericks 10.9.3 and 10.9.4 virtual machines, resolves an issue with Parallels Desktop 9 failing to update, and ensures that network connectivity remains after resuming a virtual machine.

Fun Way to Send Attachments in Mail
If you're working in a file that you want to attach to a message in Apple Mail, you can transfer the file to Mail easily: From the title bar of the file's window, drag the little proxy icon to Mail's icon on the Dock. Your Mac will make Mail the active application and open a new outgoing message, with the file attached.
(If your icon won't drag, the file probably isn't saved.)
