This will allow the app to check every ten seconds, if the selected threshold above is still available. Then tick the box below, so both boxes are ticked. For the first one, set the threshold level to the maximum (which is 2457mb). Open it and go to the preferences of 'Memory Clean'. Set everything to low in the graphic settings, exept the 3d resolution, which you set to 720p.(Maybe you can experiment setting it to 1080p.) Then download the app 'Memory Clean'* from the App Store (free).
Freezed for me as well, but now I found a solution.
