Now, when I try to reinstall it and error message pops up saying my computer needs to run iOS 10.6.4 or later, even though my OS is Yosemite 10.10.4. Any suggestions?</P> Thu, 16 Jul 2015 17:12:10 GMT https://forums.autodesk.com/t5/autocad-for-mac-forum/version-error/m-p/5723465#M16232 sdgtn 2015-07-16T17:12:10Z https://forums.autodesk.com/t5/autocad-for-mac-forum/version-error/m-p/5723471#M16233 Welcome to Autodesk Forums!<BR /><BR />Hi,<BR /><BR />If you talk about AutoCAD 2013 for Mac, you need to download new installer with all Service Packs integrated in it from here:<BR /><BR /><A href="http://knowledge.autodesk.com/support/autocad-for-mac/downloads/caas/downloads/content/autocad-2013-for-mac-full-version.html" target="_blank">http://knowledge.autodesk.com/support/autocad-for-mac/downloads/caas/downloads/content/autocad-2013-for-mac-full-version.html</A><BR /><BR />With this installer you will be able to install AC 2013 on Yosemite.<BR /> Thu, 16 Jul 2015 17:16:54 GMT https://forums.autodesk.com/t5/autocad-for-mac-forum/version-error/m-p/5723471#M16233 maxim_k 2015-07-16T17:16:54Z
