Mac FTB Issues after new Mac OS update?

[XeviousH]

I just updated to 10.8.3 from 10.8.2 on my macbook pro 15" retina. I used to have trouble running ftb on my mac pre 10.8.3 but I resolved that issue. After googling around, I learned you have to disable java 7 and enable java 6 which i did, but you also have to put -XX:MaxPermSize=128M in the java parameters. FTB worked because of this and all was good until I updated to mac os 10.8.3. Alongside the up date was a mac smc 11 update or something like that. I'm pretty sure these updates messed up ftb. (I played ftb 15 minutes before updating and it was fine) Could someone please let me know how to fix it? When I launch feed the beast after the update, it just laggggs like crazy. I cant even move, but the game doesnt crash or anything. It just lags like crazy. Help me please i wanna play ftb.

BTW. this is happening on a server. I dont really play ssp much

Check out my post http://forum.feed-the-beast.com/threads/mac-osx-crash-after-short-time-solved-mindcrack-pack.16326/

Use this in your additional Java Parameters

-Xms256m -XX:PermSize=128M -XX:MaxPermSize=256m

That solved it for me

Thank you so much! FTB works now. I normally play on a pc though but I sometimes use my mac to check up on stuff.
