Parallels put out an update that killed preexisting functionality relied on by many users without notice trying to get them to subscribe to the PRO edition.
They claim users should have known...
"We apologize for any inconvenience. On some Mac computers, several features of Parallels Desktop for Mac Pro Edition were available for use by Standard Edition users. The issue was fixed in the latest update (12.1.0) and as a result, you may have lost this functionality. The difference in the amount of memory and vCPU quantity that can be assigned to a virtual machine in different Parallels Desktop for Mac editions is documented in the Parallels Desktop User's Guide (http://download.parallels.com/desktop/v12/docs/en_US/Paralle... Desktop User's Guide.pdf): page 100 and 127 respectively."
Page 100 and 127? Really? This limitation has not been put on any previous version Parallels and was not enforced on the current version until the most recent update. It was not on any front page comparisons of their products I have ever seen. Suddenly with the update it just doesn't work anymore. Parallel's doesn't seem to care one bit for its longtime faithful users. Sad!
