Unfortunately for you, none of the boxes are MAC friendly.

Maybe check out this thread on another forum: Here is a link that might be useful: Design Software discussion

You don't need a design program for that. All you need is MS Paint or similar graphics program and you can edit a photo any way you like. I don't use it myself but several of the regulars here do so I'll let them provide the details :-) You may need to get a little creative when superimposing the graphic of your tree selection on the photo. Not positive but I don't believe Paint comes with any clipart type symbols or graphics. But then most LD programs have only very generic plant graphics as well.

SketchUp for sure. You can get a 31 day trial for free. Download the pro version. Autocad yes. I'm not sure I'd suggest Autocad. I use it because I have it. These days you don't "have" anything in the software world; you rent it. There have been other recommendations in Houzz forums for residential design software. Do a search or maybe someone will chime in here.
