What I'm curious about is why your tests even failed for the other options. A 5 MB download occurs upon initial use of Core5 A classroom of 25 students consumes 150MB of bandwidth per 30-min session (equivalent of needing 51% of a T1). Bandwidth: A typical student consumes 1MB of bandwidth perĥ-min block.Persistent Internet connection (required).1024x768 screen resolution (recommended).So far, the only alternative solutions we have thought of are to get a different type of laptop(hard to do) or to use the Google Chrome 70 web browser (official) stable version for 32-bit within Ubuntu Linux ĭo you have any suggestions on other possible solutions? Google has not released official versions of Chrome to the public yet. Lexia was unable to load, similar to with the Ubuntu laptops. We tried installing Chromium OS, which is basically the open source version of Chrome OS. What we have are some old Macbooks that run Mac 10.7, dual-installed with Ubuntu. It basically requires Windows 7 and up, Mac OS 10.9 and up, and Chrome OS. Lexia Core5's requirements are shown here. Would like some advice on getting Lexia Core5 Reading® working on old Macbooks for students at a school.
