When you startup your macbook, the cursor is invisible or it does not appear on the screen. I recently updated my macbook pro to El Capitan 10.11.4 and this problem started to appear. I combed through the system logs and the only thing that stood out to me was May 16 08:00:12 localhost com.apple.xpc.launchd[1]: assertion failed: 15E65: launchd + 180050 [527954A7-A0F1-305E-B26A-7E632B2CA0FB]: 0x1 but that did not seem to relate to anything specific.

Here is how you can clean a macbook pro screen There was a little bit of confusion for people trying to figure out how to clean a retina screen. I recently visited an apple store and the apple employee told me not to use any alcohol based cleaners or any glass cleaners like windex. I asked if they had any cleaners in the store, and he showed me one they carried.
