It's not just CUDA, any installation that uses Installer.
well first step is to find out why your Kernel cache not building. If it's just the Cuda drivers, then it could be due to smbios since that installer is targeted at specific MacPro models only
I also tried to install Microsoft Keyboard drivers, Logitech Mouse Driver, iTunes... all of them failed.
I can only install apps whose install is via drag and drop.
As far as I can remember, no custom kexts. No rollback.
Do you use custom kexts such as rollbacks?
I can see the message, but it didn't work.
Seems to be a GateKeeper issue.
Type the following in terminal:sudo spctl --master-disable sudo spctl --status
If the second command returns:
You should be able to install.
PS.: I forgot to mention that I installed using MBR partiton table, because I had some problems booting Windows 7 using GPT.
Could it be the source of the problem?
