# Troubleshooting
## The graph points look broken/strange
It's possible that your graphs won't look great out of the box due to the reliance on braille fonts.
One example of this is seeing a bunch of missing font characters, caused when the terminal isn't configured properly to render braille fonts.

</figure>
Another example is when braille is rendered as a block of dots, with the non-coloured dots also appearing. This may look strange for some users, and it is also caused by misconfiguration or missing fonts.

</figure>
In either case, you may need to install a specific font and configure your terminal to use it. For example, installing [UBraille](https://yudit.org/download/fonts/UBraille/)
and ensuring your terminal uses it should work.
Another alternative is to use the `--dot_marker` option to render graph charts using dots instead of the braille characters, which generally seems better supported out of the box,
at the expense of looking less intricate:

## Why can't I see all my processes/process usage on macOS?
You may have to run the program with elevated privileges - for example:
```bash
sudo btm
```
_Please note that you should be certain that you trust any software you grant root privileges._
There are measures taken to try to maximize the amount of information obtained without elevated privileges, but there may still be some limitations.
## My configuration file isn't working
If your configuration files aren't working, here are a few things to try:
### Check the formatting
It may be handy to refer to the automatically generated config files or the [sample configuration files](https://github.com/ClementTsang/bottom/tree/master/sample_configs).
The config files also follow the [TOML](https://toml.io/en/) format.
Also make sure your config options are under the right table - for example, to set your temperature type, you must set it under the `[flags]` table:
```toml
[flags]
temperature_type = "f"
```
Meanwhile, if you want to set a custom color scheme, it would be under the `[colors]` table:
```toml
[colors]
table_header_color="LightBlue"
```
### Check the configuration file location
Make sure bottom is reading the right configuration file. By default, bottom looks for config files at these locations:
| OS | Default Config Location |
| ------- | -------------------------------------------------------------------------------------------------------------------------------------- |
| macOS | `$HOME/Library/Application Support/bottom/bottom.toml`<br/> `~/.config/bottom/bottom.toml` <br/> `$XDG_CONFIG_HOME/bottom/bottom.toml` |
| Linux | `~/.config/bottom/bottom.toml` <br/> `$XDG_CONFIG_HOME/bottom/bottom.toml` |
| Windows | `C:\Users\<USER>\AppData\Roaming\bottom\bottom.toml` |
If you want to use a config file in another location, use the `--config` or `-C` flags along with the path to the configuration file, like so:
```bash
btm -C path_to_config
```
## My installation through snap has some widgets that are blank/show no data
Make sure bottom is given the correct permissions. [Snapcraft](https://snapcraft.io/docs/interface-management) explains how to do so.
