Q: Upgrading to 64 bit

64-bit Logic does not require the Mac kernel to be running at 64 bit to have full access to the 64-bit OS.

Under "Get Info" for the Logic app you have Logic running in 64-bits, correct?

If you are already using Logic in 64-bit mode try this:

Using "get info" set Logic to open in 32 bit, Let it validate all the plugins, close Logic, set it back to opening in 64-bit.

I doubt if there is or will be any EFI updates for older machines.

Yeah, judging from your first post I thought you had probably tried it... odd that Waves requires the 64-bit Kernel, I wonder if it has to do with their copy protection?

How did you upgrade your Waves 32 bit plugins to 64 bit?

I need to do this so that I can use my Waves plugins in Maschine Studio 2.0 while in 64 bit mode.

Thanks

See my reply to your other thread.... on the same subject..
