I work on a Mac. And the best I've tried up till now is Font Explorer X Pro. It's excellent!
After so many nervous breakdown, my definitive software is Fontagent Pro :
Let him manage your fonts and the life become so nice
I use BitStream Font Navigator, it comes with the Corel Suite, but it keeps uninstalling the fonts and other kinds of bugs.
Ill give a try on the some of these you recomend.
Use Extensis products you will not be disappointed. They are professional products and very stable.
In particular the auto activation feature is very practical when you have several fonts in the same file.
Font Explorer X Pro 3.1. It's excellent!
i use corel bitstream font navigator
I'm using Font Explorer X on Mac and am pretty satisfied with it.
I would also recommend FontExplorer X Pro by Linotype. I use this as work after having giving up on Suitcase Fusion. I found Suitcase Fusion to give poor performance - crashing, not auto-activating etc.
I have had no problems at all with FontExplorer. I am still using Suitcase Fusion at home but it doesn't have to work as hard or juggle as many fonts.
i think font expert 2011 and font explorer are good!
I think Suitcase Fusion 4 is better! It has mac&win versions, and Adobe plugins.
I'm a suitcase user and have been for some time now, but after reading the replys I think I may also have a little look at Font Explorer Pro for Mac.
