It happened, that when I upgraded to Lion, for some reason Preview stopped working. This was new to me - usually I don’t expect such behavior under Mac OS. Seems that lots of people had this, especially the ones that have upgraded MBP with SDD and having HDD at the place of Optical Drive. In this case you make SymLinks in your home directory pointing to HHD for Downloads (for Photos, Music, Movies or anything that you can afford to play from slow media and takes more space, which is expensive on SSD).
Today I have tried to connect to my company’s VPN. Few days ago I have already upgraded my Snow Leopard with Mac OSX Lion. When trying to start RSA SecurID to obtain my token, the application responded with: “Error loading the application. Contact your administrator.”
When trying to search for solution, I found this post in Apple support forums:
There some guy from RSA says that they know about the issue and are working to fix it for next version, which will be available in September.
