Downloaded Lion and it installed fine but now realize most of the apps I use everyday are not compatible. Anyone know how to uninstall or go back to 10.6.8? Nothing posted on Apple support. I tried restoring my last Time Machine backup before the upgrade ... no good. Tried installing Snow Leopard from my disc ... wouldn't accept. Tried switching startup disc to Snow Leopard CD and restarting ... no good. I have a new iMac with wireless keyboard and mouse. That seems to create a problem of holding down a key while I restart. Any suggestions?
