Apple are finishing off work on their next update for Mac OS X Lion, 10.7.4, and developers will soon be able to get their hands on it for testing, AppleInsider reports. The release will at first be restricted to several developers, but by the end of the week, it should be out for all devs to download.
This update will also likely be one of the last before the summer move to 10.8 Mountain Lion. The last update, 10.7.3, was released in early February and provided support for new languages and WiFi connectivity fixes among other things.
