how to fix preview crashing (spinning wheel) when editing a pdf
im using macOS High Sierra and anytime i open a large PDF with annotations (for example a textbook containing highlights or annotations), preview begins to lag immediately and within a few clicks preview freezes (spinning wheel comes on). Sometimes this can take many minutes to unfreeze, but usually it remains unresponsive and i have to force quit preview.... this is not a productive way to work. im assuming this can be fixed?
thanks
