I recently installed Lion (Mac OS X 10.7.3) on my early 2008 MacBook. I know many of the color changing options in Mail and iCal have been taken away (probably due to app syncing or Cocoa issues). I can live with this as long as the result is legible.
In Mail, the list of Mailboxes is listed in a light blue color, with black letters which turn a transparent white or silver when selected - difficult to read. My work-around has been to list my more frequently used Mailboxes in the toolbar, but I have too many Mailboxes to put them all up there. Any suggestions?
In iCal, I can live with all of the ugly artificial leather stuff, but my main issue is the definition between dates and days in each view (Day, Week, or Month) is so light it is almost invisible. Only when an entry is made is the data legible but the times and dates above and below are not. Again, any suggestions? Do I need to upgrade my laptop to get a higher resolution?
