OK so about APFS, I have installed the latest DP6, ran Disk Sensei to get trim kext in place, then ran Trimforce. Right now i have the latest build, the latest firmware, and trim on my samsung SSD.
However, it will not let me convert my SSD to apfs. I have tried via an install usb, via recovery, and via disk utility in the actual os. None of them give me the option to convert.
Any ideas that can help me?
No idea on this matter yet. If that's Apple's artificial limitation, better not to do a "force conversion" at this moment. It's just a beta, not worth to find any complicated work around may become useless on next update. Also, may be the APFS can work on cMP, but only on a newly formatted partition. May be it can't boot after a manual conversion, who knows? Especially we have the 2nd firmware upgrade, IMO, that's a indication that Apple is trying to fix something.
