MacOS syscall, fs_event, syslogd discovering

## Syscalls
```
sudo syscallbypid.d
```

## FS Usage
```
sudo fs_usage
```

## Syslog view
```
/usr/bin/log show --last 10s --style compact
```

## Syslog filtering
```
/usr/bin/log show --last 10s --style compact --predicate 'messageType == error'
```

## Setup syslogd level threshold
1. `sudo nano /etc/asl.conf`
2. Change `notice` to `error` - `? [<= Level error] file system.log`

Before:
```
# Rules for /var/log/system.log
> system.log mode=0640 format=bsd rotate=seq compress file_max=5M all_max=50M
? [= Sender kernel] file system.log
? [<= Level notice] file system.log
? [= Facility auth] [<= Level info] file system.log
? [= Facility authpriv] [<= Level info] file system.log
```

After:
```
# Rules for /var/log/system.log
> system.log mode=0640 format=bsd rotate=seq compress file_max=5M all_max=50M
? [= Sender kernel] file system.log
? [<= Level error] file system.log
? [= Facility auth] [<= Level info] file system.log
? [= Facility authpriv] [<= Level info] file system.log
```

## See error IP details
```
