Re: [ANN] Bither - simple&secure Bitcoin wallet.(iOS v1.3.2 + Apple Watch)
Trying to generate the vanity address on MacBookPro9,2 fails when trying to use integrated Intel HD 4000 GPU. Works fine with CPU, it's just very slow when it comes to more than four character long addresses 
I'm one of Bither's developers. I can't generate vanity address with the integrated GPU on my Macbook either. After some digging, it turns out that there are some bugs in Apple's OpenCL driver. Unless Apple fixes this problem, we won't be able to use our integrated GPU for OpenCL computation. We'll continue digging into this. Thank you for trying our wallet.
