Yeah.. I used LiteIcon too.. It'll give you a warning about being not being compatible, but it seemed to work fine. Just be aware, this is a beta release, so any future update may write over any new icons you add because they still seem to be tweaking them. I lost custom icons between DP2 and DP3.. they seemed to stick with DP4 (or public beta)..
Thanks for the offer, appreciated. But i managed to find the originals in the 10.9.4 core.
If anyone else needs the original maverick system icons they are here.
Ive organised them into folders to make it easier for people.
The best option to replace the icons post candybar seems to be the lighter weight app called LiteIcon
If anyone does decide to use them just give us a thumbs up! cheers
