hi hoping someone out there can help me, i have autocad 2014 for my macbook pro retina, its a 16GB ram and 2.3 Ghz i7 processor. After copy and pasting drawings my files have become too large and therefore the files stutter and end up crashing the whole program resulting in me loosing my previous work. i found this software online 'AutoCAD® DGN Hotfix' to resolve the problem however it looks as the it only works for windows.
Any suggestions ???
