I recently did a fresh install of Anaconda3 and SMAK on a M1 Mac. While my previous installation of Anaconda and SMAK proceeded exactly as described on the installation webpage, this time I came across some hurdles. 1. While I believe that I had installed my previous Anaconda3 for all users, the "/opt/anaconda3" direcoty was in my "User/opt/anaconda3" directory as described in the installation instructions on sams-xrays. Yet this new installation installed in "/opt/anaconda3". i.e. directly on the Macintosh HD, not in the user directory. I may be mistaken about my previous install, but it is worth noting that maybe something changed with the installation defaults. Anyway, this meant that my shortcut no longer worked and I had to edit for the new directory. 2. The command for creating the smakenv "conda create -n smakenv python==3.10" created the environment in the "osx-arm64" architecture. i.e. the Apple Silicon architecture. The previous architecture is "osx-64". Not a problem unless you want to install the additional segmentation and image registration modules. When running the "conda install lap -c conda-forge" I got an error: "Packages Not Found Error: The following packages are not available from current channels: -lap ......" This is because this "lap" package does not have a version that works for osx-arm64. Solution: When you create the smakenv, use "conda create --platform osx-64 -n smakenv python==3.10". This creates the smakenv in the architecture that allows you to install the lap package.

Hi - another error for installation has been reported. We should get this in the installer in release 3.10, but until then, a new version of PyMCA was released using numpy 2.0, which breaks SMAK. Once there is a more uniform use of numpy 2.0 across all dependencies, SMAK will upgrade to numpy2.0 as well, but for now, we have to stick to the old version. If you run into a numpy error in pyMCA when running smak, please downgrade pyMCA for now: “pip install pymca5==5.8.2” PyMCA 5.8.2 will definitely work, and maybe up to 5.9.0.... Cheers!

Ok, for the Mac people out there, you can follow these steps... (1) Open "Automator" on your Mac (2) Create a new application, you can call it anything you like (I called mine RunSMAK) (3) Crate a new step from "Run AppleScript" (4) Your AppleScript should contain: on run tell application "Terminal" activate do script "cd /YOUR_DIRECTORY_TO_SMAK/; python smak.py" end tell end run (5) See the install instructions for how to located your directory, but it will probably be something like: /Users/yourUsername/anaconda3/envs/smakenv/lib/python3.10/site-packages/smak. (6) Save this application, and then you can drag it to your desktop and/or applications folder!
