Some MAC Issues and solutions (M2Max Studio)

[danryan28]

I had a MAC Mini 2015 and my OWC/LG external drive crapped out. So, what to do? Let's upgrade to a Mac Studio with M2 Max chips and new drives!! I do 3D Resin printing, so it's not just for movie ripping!!

The new Setup:
Mac Studio
Chip: Apple M2 Max
Total Number of Cores: 12 (8 performance and 4 efficiency)
Memory: 32 GB

OWC Mercury Pro with WH16NS40 drive

New MACOS security says that the MakeMKV package is not from trusted source.
Error Message: "MAKEMKV" cannot be opened because the developer cannot be verified. macOS cannot verify that this app is free from malware.
Fix:
MACOS Pre Sonoma
Open System Preferences -> Security & Privacy -> General
Click the <Open Anyway> "button next to MakeMKV in the list in the bottom half of the window

MACOS 14.x
Open System Preferences -> Security & Privacy
Click the <Open Anyway> "button next to MakeMKV (You have to scoll to the bottom!)

Second issue: "MakeMKV would like access to files on a removable volume" for EVERY disk!!
Fix (Note: It looks like this is required every time you upgrade MakeMKV. Also, this requires that apple XCODE Apple developer tools be installed from the app store. I also have the CLI tools installed, but not sure if that is required or not. If someone could let me know I will update the post):
1. Quit MakeMKV
2. Open System Settings - Privacy and Security - Files and Folders and look for makemkv (but with a black terminal icon), and delete it!
3. open terminal and run:
codesign --force --deep --sign - /Applications/MakeMKV.app
Verify that MakeMKV is not showing up and has the correct icon in Files and Folders.

Third issue: When ripping a LONG/Multiple title Bluray, the drive gives an error:
makemkv Error 'OS error - (ipc/send) invalid destination port' occurred while reading '/BDMV/STREAM/00068.m2ts' at offset '0'

What did I try:
1. I tried different power supplies for the enclosure
2. I tried the new drive and old enclosure
3. I tried plugging the power supply into my UPS
4. I tried plugging the USB3 cable into a Anker USB-C Dock plugged into the Mac Studio

What finally fixed it:
I flashed the drive with the 1.2 MK firmware from this site.
Information about flashing the drives can be found here:

I would like to note that before I flashed the drive I was getting 7.4x (31M/s) speeds, and now I'm getting a max of 6.4x (about 28M/s speeds. But the errors are gone!

FYI, using codesign to get rid of the permissions dialog only works if you have a paid Apple Developer account ($99/year). Without that you just get a "no identity found" error.

No, that’s not true…I do not have a paid account. I do have the Developer tools installed from the app store.
