+# MacOS Tahoe 26.1 Users - Attention:
+Changes to USB support in Tahoe version 26.x cause sdrtrunk to fail to launch.  Do the following to install the latest libusb and create a symbolic link and then use the nightly build which includes an updated usb4java native library for Tahoe with ARM processor.  There may still be issue(s) with MacOS accessing your USB SDR tuners.
+
+```
+brew install libusb --HEAD
+cd /opt
+sudo mkdir local
+cd local
+sudo mkdir lib
+```
+Next, find where brew installed the libusb library, for example: ```/opt/homebrew/Cellar/libusb/HEAD-9ceaa52/lib/libusb-1.0.0.dylib```    Note: the folder "HEAD-9ceaa52" is the version stamp for HEAD when you installed from it.
+
+Finally, create a symbolic link from the installed library to the place where usb4java is expecting to find libusb (/opt/local/lib/libusb-1.0.0.dylib)
+
+```
+sudo ln -s /opt/homebrew/Cellar/libusb/HEAD-9ceaa52/lib/libusb-1.0.0.dylib /opt/local/lib/libusb-1.0.0.dylib

-Note: the api headers in the 3.11 folder are equivalent to the 3.08 headers.  The only
-difference from the 3.07 headers is the addition of the boolean 'valid' flag to DeviceT structure.
-
-1. Download JDK19 compatible build of jextract JDK: https://jdk.java.net/jextract/
-2. If generating on windows platform, modify the sdrplay_api.h to remove the windows
-   pieces of the file.  Specifically:
-2a. Comment out these lines but leave the *HANDLE typedef:
-
-//#if defined(_M_X64) || defined(_M_IX86) || defined(_M_ARM64)
-//#include "windows.h"
-//#elif defined (__GNUC__)

-
-2b. Remove the '_SDRPLAY_DLL_QUALIFIER' from in front of the method declarations
-
-2c. Change the 3.11 version string to 3.08 either in the header file, or in the generated java class
-
-3. Open command prompt to the root source code where the generated files should be placed:
-..\SDRtrunk\sdrplay-api\src\main\java
-
-4. Generate the code:
-c:\Users\Denny\Downloads\jdk-19-ea2-panama\bin\jextract "C:\Users\Denny\git\sdrtrunk\sdrplay-api\api\v3_11\sdrplay_api.h" -l libsdrplay_api --source
-
-5. Do this for all versions of the API.
