Sounds good - 2010 MacBook Pro, so probably not up to it.  Misconception about "lite" coin I guess.

LTC are worth about 1% of BTC, but that means there are fewer people mining them. So, relatively modest resources might net a complete LTC or two per month. At $3.51 per coin (at this moment), that might pay for electricity and wear and tear on your GPU, or it might not. The more efficient your GPU, the more chance of it being profitable.

If you want a side gamble that LTC will rise in value, then whether or not it's profitable now might be less important. As Bitbacco said, however, scrypt mining is hard on your system. It also doesn't seem to like Nvidia GPUs.

I keep adding features as I can, and that would be a good one so it's on the list now! I probably won't charge for it, I like keeping it open source, I did think about doing some themes for it and charging for those as an optional extra but right now the list of useful features is too long for me to be focusing that much on the appearance!

It hadn't come to mind yet, to tell the truth I run the fabulous panda p2pool node on Linux because it makes a better server - I don't think I will make a GUI for p2pool mainly because it's written in Python which makes it a bit of a PITA and I have no use for it personally whereas I use MacMiner 24/7. If there was a lot of demand for it I might consider it because it would be good for p2pool.

Hmmm, I thought one of the release notes said that the miners would automatically restart when you restarted the app. I'm not seeing that though...

My mac mini is set to automatically reboot once per week (headless server that runs a lot of apps... some of which have leaks or get stuck), and has all my relevant apps set to start automatically after the restart. But MacMiner just launches and shows the BFG Miner window in a stopped state, rather than the FPGA Miner in a 'running' state.

My wife turned on her hairdryer this morning and it popped the circuit breaker that my my BFL Asic was on.  Now, macminer won't work!  I installed windows on a separate partition and I know it's not the miner because it works fine on bfgminer on the windows side.  I tried to update and now it comes up with an error and then the indeed window every few seconds..

The release notes said MacMiner restarts bfgminer if bfgminer quits unexpectedly, but the feature to start automatically when MacMiner is opened hasn't been built in yet

TR4L I'm guessing the device may have changed name, have you set -S all or the specific device? If the latter try

cddev/
ls -l cu.*

unsure about the fury devices yet, support is built in to bfgminer but not sure about usb drivers, please do let me know what you find when it turns up!

I have tried reinstalling and all of the above and it still says this:
dyld: Library not loaded:Applications/MacMiner.app/Contents/Resources/bfgminer/lib/libblkmaker-0.1.0.dylib
  Referenced from:Users/TR4L/Downloads/MacMiner.app/Contents/Resources/bfgminer/lib/libblkmaker_jansson-0.1.0.dylib
  Reason: image not found

So... adding '-S opencl:auto' to the "Manual flags" section of MacMiner certainly seems to resolve this and gets the GPU involved, but... bfgminer is still using all available CPU (100%). Seems the -t switch sets the number of CPU threads to run, and NOT having the CPU run at 100% results in a higher Mh average (likely because the CPU's not waiting to then process what the GPU has sent it). So I'm running with the following in "Miner Settings > Manual flags":

-S opencl:auto -t 0

I did try it with -t 1 and, again, average Mh was quite a bit lower.
