I have AutoCAD LT for iMac for a month. Since the begging AutoCAD doesn't open fully when tried for a first time everymorning. It always required  FORCING TO QUITE cause AutoCAD crashes and than when I try to open Application again it works. Happens everytime.

Also, when I finally open AutoCAD second time, it gives me a message that Upgrade is available. I click to download it and it has 3 MB. By finishing 99% of download it stops and never completes. So I cannot do update at all. 

Can you please check this, cause I bought AutoCAD online to ensure I have fully uptodate version , always running on my iMac and now it seems to be a little anoying

regards
