[OS X TeX] Applescript to help update the Engines folder after a TeXShop update

[Nathan Paxton]

	Ramon,

	When I run this script, I get the following error: error "find: -exec: no terminating \";\" or \"+\"" number 1 for the line:
set command to "find ~/Library/TeXShop/Engines -name '*.engine' -type f -exec md5sum {} // ;"


	How can I fix the script?

Thanks in advance for your help. 

Best,
-Nathan
