Made the "Poor Performace" paragraph bulleted for the steps to take instead of having one piece of text.

If you encounter errors when trying to start the Web UI with `./webui.sh`, try deleting the `repositories` and `venv` folders from your `stable-diffusion-webui` folder and then update web UI with `git pull` before running `./webui.sh` again.
### Poor Performance:
Currently GPU acceleration on macOS uses a _lot_ of memory. If performance is poor (if it takes more than a minute to generate a 512x512 image with 20 steps with any sampler) first try starting with the `--opt-split-attention-v1` command line option (i.e. `./webui.sh --opt-split-attention-v1`) and see if that helps. If that doesn't make much difference, then open the Activity Monitor application located in /Applications/Utilities and check the memory pressure graph under the Memory tab. If memory pressure is being displayed in red when an image is generated, close the web UI process and then add the `--medvram` command line option (i.e. `./webui.sh --opt-split-attention-v1 --medvram`). If performance is still poor and memory pressure still red with that option, then instead try `--lowvram` (i.e. `./webui.sh --opt-split-attention-v1 --lowvram`). If it still takes more than a few minutes to generate a 512x512 image with 20 steps with with any sampler, then you may need to turn off GPU acceleration. Open `webui-user.sh` in Xcode and change `#export COMMANDLINE_ARGS=""` to `export COMMANDLINE_ARGS="--skip-torch-cuda-test --no-half --use-cpu all"`.
