I'm installing AutoCAD LT Mac 2024 on a second (new) MacBook Pro which also has my Dropbox synced to the local hard drive. It is a fresh install on this new machine with existing license. When I use File > Open (in AutoCAD LT) and navigate to the local Dropbox .dwg file and click 'Open,' I get the error message 'Drawing file is not valid.' BUT, if I navigate to the same file in my MacOS Finder and double-click on it, it opens as normal. It's incredibly frustrating and makes LT almost unusable. A few notes:
- I used the same exact setup on my old MacBook Pro for years through AutoCAD LT Mac versions 2020 thru 2024. (It's just this new install that I'm having problems with on the new MacBook Pro.
- I can open the same .dwg files in a different directory if copied (Desktop, from a flash drive, etc.) with File > Open as expected.
- If I open the file through the Finder (as described above) and re-open AutoCAD Lt Mac 2024, I can open the file through the recent screen at boot-up.
- Attached are screenshots showing the errors (1=open via file > open, 2=error message, 3=open same file from finder and double-click, which opens the file as expected)
Any thoughts?
