to LAStools - efficient tools for LiDAR processing

I have installed and pointed to the folder with the Lastools, but every command I try I get the could not find command message.

Then looking in that folder, it is mostly EXE files?

Will this work on a Mac?

cheers,

If you search for "lastools mac" the first result wil be an article about how to use wine with lastools.

The difficulty is that Wine is not supported on the current versions of MacOS, nor is it likely to be support on the newer M1 based Macs.

Have you given a though at trying virtual machines/desktop on azure or aws? It has the downside that you need an internet connection but it’s a nice way to ‘run’ exe from a Mac. Setup takes about 10 minutes.

The question was about how to run lastools on a MacOS. Your answer is “here’s a way to buy and run Windows”.

Building the open source subset of lastools is pretty easy. I just downloaded and unzipped the LAStools.zip file on my mac (runs macOS 10.15.7 Catalina). Then:

The basic functions seems to work fine. Obviously, running the other tools that are compiled for Windows only is not possible (other than via a windows VM which would be really overkill). Then again, building the whole set of tools for macOS does not look like an impossible task. The interesting exercise is to now build the open source tools for an M1 mac (I did this on a Intel-X64 mac).

Hi Albert, Hi Martin,

I can confirm that if works on MacBook Pro M1 laptop. Just compiled it and run the same test as Albert.

Same warnings and same test results.

Have a nice one.

Antoine.

That’s great to know.

It would be nice doing some performance benchmarking on a M1. I think it should perform nicely. Probably better than an X64.

It worked for me too. Thanks for sharing
