This may or may not be important, but I recently discovered a trick for making straight lines on a Mac computer that you may already know about.
Anyways, this is the trick:
1)You hold the 'control' key near the bottom left.
2)You use the mouse to make a dot where you want the line to start.(A box will appear and that has controls like "zoom in/out,print,quality,settings,ect." but you don't need to do anything to the box. Just ignore it.)
3)You make another dot where you want the line to end but you hold the mouse down.
4)Release the mouse and as soon as you release it, then quickly let go of the control key.
If it worked, you should have a straight line!!
I hope that helps with other mac users who are asking for help with straight lines! :)
