Hi All,

I had AutoCAD LT Mac 2013 installed on a Mac Pro using Mavericks.  I updated to yosemite and everything was working fine.  I recently installed a new SSD and migrated my applications to the new SSD.  That broke ACAD LT 2013 from starting anymore.

I see that there is now a service pac 3 for yosemity compatibilty BUT since ACAD broke I tried to re-install and had to remove ACAD LT 2013 to try that so I removed it.  Now Yosemite keeps stopping the installation and I get an error message saying that operating system not supported, you need OS 10.6.4  at a minimum.

How are we who have had ACAD uninstalled supposed to apply the patch if we cannot install a fresh copy of ACAD 2013?????  We own that program, I hae afull license, and are out 1,200 bucks due to Yosemite incompatibility for a fresh installation to apply the new service pac.

AutoDesk, do you have a solution to this problem to keep your customers up and operating??  I am a sole proprietor and cannot afford to upgrade to ACAD LT 2015 at this point and I cannot work without AutoCAD.

I have installed Draftsight 2015 temporarily to keep my present projects going but I need my purchased copy of ACAD LT 2013 to work using the provided update for Yosemite compatibility.

Any help is greatly appreciated.
