Ugh... I just upgraded to El Capitan, rebooted and tried to fire up my Fusion 7 VMs to make sure everything was ok. I can see the Bootcamp partition from Finder, but when I try to start it in Fusion I get an "Operation not permitted. Cannot create the disk '/users/.../Boot Camp.vmdk' or one of the snapshot disks it depends on. Module Disk power on failed."
I tried this VMWare KB article without luck: http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1003483
Basically close Fusion and delete the Book Camp VM directory, then re-import it from the Boot Camp partition. (like you would have done the first time you created a Boot Camp VM)
Anyone else having this problem? I can't boot into my Windows development VM now. Nice.
Update I re-enabled the boot recovery partition in OSX then tried rebooting into it so I can attempt disable "System Integrity Protection". There is no "Security Configuration" setting under the Utilities menu. It's completely gone. I have no clue how to disable this feature and use Fusion 7 with Boot camp.
What a mess. Why would Apple enable so many major security features that would break a number of the largest and most popular applications on its platform? I can't upgrade to VMWare Fusion 8 Pro without paying $120 USD. Great timing.
