I installed this Update on 3/18/2010 and have had nothing but problems. (Cant access large files on Share drives/corrupted file errors, unable to execute exe files) I had to restore my mac to a 4 day old backup to recover my VM image. I dont understand how a patch like this be released. it is more than obvious to me that no testing was done done on it and I cant see how a company that values there customers have not issued a fix or patch to fix this issue. I guess I will be going to VMWare soon. Sad.
